Jandy® Pro Series Nicheless Underwater LED Light Operating Instructions 4.1 Light Synchronization NOTE This section only applies to the color (RGBW) lights. All fixtures must be tied into the same transformer, circuit or switch for synchronization to occur. 1. Turn the light ON. If the light has been off for 7 seconds or longer, the light will turn on at the last color selected. 2. To synchronize multiple lights to the same color mode, you.will need to reset to the beginning of the color mode sequence. With the lights ON, turn them OFF for five (5) seconds, then turn ON again. All of the lights will reset to the Alpine White color mode. If all of the lights are not in the Alpine White color mode, they have not been synchronized, repeat step 2. Nicheless Underwater LED Lights I Owner's Manual Page 11 4.2 Operating the Light 3. To change the color mode, turn the light OFF for one 1-3 seconds. Continue turning OFF and ON until the desired light color mode is reached. See Table I for the color mode sequence. Example: If you followed step 3 and are now on Sky Blue and want the lights to be Violet, then the lights must be turned off and on 7 seven times to bring you to Violet. Sequence Order Color Modes 1 Alpine White 2 Sky Blue 3 Cobalt Blue 4 Caribbean Blue 5 Spring Green 6 Emerald Green 7 Emerald Rose 8 Magenta 9 Violet 10 Slow Color Splash 11 Fast Color Splash 12 America the Beautiful 13 Fat Tuesday 14 Disco Tech Table 1. Color Mode Sequence 4. The lights have memory. If the lights are off for 7 seconds or more, the next time the lights are turned on, they will return to the last color mode they were on prior to being turned off (Step 1 listed above). This function allows you to keep your lights returning to your favorite color mode every time the lights are turned back on. NOTE To synchronize colors on multiple Jandy® Pro Series Nicheless Underwater LED Light systems wired to separate switches, perform the above actions on all of their switches simultaneously. All Jandy Pro Series Nicheless Underwater LED Lights will synchronize automatically if activated by the same switch. No other accessories are required. Page 12 Nlcheless Underwater LED Lights I Owner's Manual Section 5. Designer Lens Options The Designer Lenses offer a unique set of options for the LED Series of lights. Each one has the ability to create unique lighting effects within the pool's interior. See the list below to learn more about the designer lens options. 7 `K HALF DOME - This escutcheon adds over the existing lens to allow you to direct 1/2 the light in a direction you want. Downwards -to light a pools interior without light shining upwards. Upwards to light a water feature or sideways to put light where it might be needed but no where else HALO LENS - This lens allows for gentle lighting in an area but knocks down the center beam. This allows for installation on walls, etc. where there might be an opposite wall, etc. where you want to eliminate generating a "hot" spot. Great general lighting but softly. SPOT LENS - Just the opposite of the Halo. Concentrates the light and reduces the output at wider beam angles in order to produce a spot -light effect. Great for illuminating that special feature. CATS EYE - This lens reduces the light to just a "slice" of light that is broad but thin. An incredible effect for illuminating but without spilling light all over. DIAMOND - WOW want to really create something special? The Diamond lens creates incredible points of light throughout the interior. The points will be different the farther away from the light they are. Put the LED colored light on DISCO TECH MODE AND WATCH THE FUN BEGIN!

Poolguard Pool Alarms have been tested and comply to the ASTM Standard Specifications for Residential Pool Alarms ASTM F 2208, in a 16' x 32' pool. POOLGUARD alarms can be used in pools up to 20' x 40' or 800- square feet. FIGURE 2 Pools 800 Square Feet and Smaller. (Cont. on next page) PLACEMENT IN rrOUR POOL (Continued) POOLGUARD automatically compensates for variations in pool levels within the unit's operating range. The unit utilizes a sensing throat which projects into the water and is designed to operate in most pools with an in -wall skimmer. The sensing throat cannot be less than 2.5 inches, (See Figure 3), and not more than 5.5 inches into the water, POOLGUARD recommends that the sensing throat be approximately 4 inches in the water POOLGUARD can be used with SOLAR BLANKETS on the pool. POOLGUARD can also be used in spas. 12 3/4" 14 1/2" SENSINGTHROAT CANNOT BE LESSTHAN 2.51'IN THE WATER, POOLGUARD RECOMMENDSTHAT THE SENSING THROAT BE APPROXIMATELY 4" IN - THE WATER IMPORTANT I3 1/2" SUPPORT BLOCK FIGURE 3 POOLGUARD may not function properly if your pools water level is not maintained within the required levels of your alarm. Also, the unit may not operate effectively while certain types of automatic pool cleaners are in operation. Some irregular shaped decks may not provide a level foundation for the unit by the pool's edge. This minor problem can be overcome by appropriately supporting the unit, (See Figure 3). STABILIZING YOUR POOL ALARM The Alarm Stabilizing Pin (ASP) is factory installed onto your pool alarm. Tools needed to install your alarm are: One 5/16" masonry drill bit that can be found at your local hardware store, a drill, a pencil, a tape measure or yard stick. 1. Position your pool alarm so that the sensing throat is in the water and the ASP is touching the deck, (leave a small space no more than 3/8" between the sensing throat and the top edge of your deck or coping), (See Figure 4). 2. Mark with a pencil the spot where you wish to drill the hole for the ASP. 3. With the 5/16" masonry drill bit, drill a hole 2 1/4" inches deep, as straight as possible. (Cont. on next page) STABILIZING Y1.JR POOL ALARM k�ontinued) 4. Clean off the debris and install the alarm by placing the ASP into the 5/16" diameter by 2 1/4" deep hole. 5. Your Pool Alarm is now ready for use. If you have any questions or need help with installation, please give us a call at 1-800-242-7163. 6. Be sure to keep your ASP hole clean from debris and dirt so that your alarm will always lay flat on the pool deck when installed.

TEST BEFORE USING To ensure effectiveness, test POOLGUARD every time you place it into the pool by performing the following procedure: •POOLGUARD DOES NOT HAVE AN ON/OFF SWITCH When the alarm is in the pool it is always in the ON position and cannot be turned off. When the alarm is out of the pool it is always in the OFF position. •To test your alarm push an object of appropriate volume and weight off the deck edge at the farthest location from the alarm. (A four (4) gallon jug of water or 3-one (1) gallon jugs of water tied together are ideal for testing.) The alarm should sound when the water action caused by the intrusion reaches the unit. It may take a few seconds for the alarm to react to the water action. (Cont. on next page) TEST BEFORE USING (contin *After resetting the alarm and allowing time for the water action to settle, repeat the procedure from another point in the pool until you are confident of detection performance. •POOLGUARD includes a timer function which automatically resets the unit after the alarm has sounded for approximately 5 minutes. ADJUSTING YOUR RETURN LINE FITTINGS The POOLGUARD alarm should not be placed too close to a return line, also do not place POOLGUARD in a location in the pool where a return line is pointing in the alarms direction. Water turbulence may be too strong, falsely setting the alarm off or the water turbulence may interfere with the alarms ability to detect an intrusion. If you have more than 2 return lines please call customer service at 1-800-242-7163. It is very important in pools to adjust all the eyeball fittings on your return lines so that the water flow will not interfere with your pool alarm. Point all the eyeball fittings down and your pool will still circulate properly and this will allow POOLGUARD to function properly, (See Fgure 5). Pointing the eyeball fittings down also helps prevent algae growth. - FIGURE 5 CORRECT INCORRECT POOLGUARD REMOTE RECEIVER The POOLGUARD REMOTE RECEIVER has been integrated with the standard POOLGUARD unit to provide a wireless remote alert operating at distances of up to 200 feet. The POOLGUARD REMOTE RECEIVER sounds an alarm in the house when the POOLGUARD unit is activated at the pool.The remote system consists of the following functional elements: •A coded pulse receiver (Remote Receiver), (See Figure 6). • A standard wall outlet power supply, (See Figure 6). The REMOTE RECEIVER is a compact unit powered by a UL and CSA approved AC/DC power supply. The REMOTE RECEIVER can be placed on a table or a counter top inside the house. The pulse coded radio frequency signal is transmitted from the pool unit and is received and decoded to sound the remote receiver. The remote receiver will sound for an additional 3 seconds after the pool unit has been silenced. If the REMOTE RECEIVER beeps once approximately every 10 seconds, it is indicating that the 9v battery in the pool unit is low and needs to be replaced. After you have purchased your POOLGUARD alarm and you wish to add another remote receiver to your alarm system you can acquire one from PBM Industries, Inc. Contact PBM by phone or mail or contact your place of purchase. POWER SUPPLY---> FIGURE 6 B Horn at 10 feet REMOTE RECEIVER TO OPERATE YOUR REMOTE RECEIVER Try to locate your REMOTE RECEIVER in.a convenient part of your house close to the pool. Avoid steel walls or any other large metal objects or obstructions that might interfere with the signal reception. The REMOTE RECEIVER has to be placed on the same level or a level above the pool in the house (do not place receiver in an underground basement). The ideal location for your REMOTE RECEIVER would be by a window overlooking your pool. Test your REMOTE RECEIVER in different locations in your house to find the best working place for your receiver. Connect the power supply to any 120V, electrical outlet and insert the jack into the receiver. Check that indicator light is on. Your REMOTE RECEIVER unit is now ready to receive a transmission from your POOLGUARD unit. DO NOT USE YOUR REMOTE RECEIVER OUTDOORS. NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER'S AUTHORITY TO OPERATE THE EQUIPMENT. SWIMMING P08L SAFETY TIPS � • Supervise children at all times. • Never permit swimming alone. Never leave a child alone, even to answer the telephone. • Always remove the entire solar cover from a pool before swimming. • Remember that alcohol and water safety do not mix. • Have your pool area fenced and the gate locked to prevent unauthorized entry to the pool, and install a gate alarm. • Lock and secure all doors in the house which permit easy access to the pool, and install a door alarm. • Have a responsible adult teach swimming and water safety to your children. • Maintain clean, clear water in the pool. • Do not swim during electrical storms. • Do not permit bottles, glass, or sharp objects to be used around the pool. • Ask your pool dealer how you can improve your pool safety — they will be glad to assist you. • Above all: remember that common sense, awareness, and caution will allow you to enjoy your pool.

APSP PBM INDUSTRIES, INC. �ya,',e 0 REV.1/2015 to 9 + o .r r SJ"l 9l 1 FALSEPoolside Unit ALARMS Power Suooty Remote Receiver All pool alarms will false alarm on occasion for different reasons. False alarms can be minimized; however, it is important to remember that a false alarm is better than no alarm at all. WEATHER & WIND—POOLGUARD sets stationary on the deck of the pool so the wind will not effect the alarm unit itself. Wind may trigger a false alarm if it is strong enough or steady enough that it causes the water in the pool to rock or bounce up and down the pool wall. When the water in the pool moves up and down the POOLGUARD sensing throat, it may finally cause the alarm to sound. On extremely windy days when the pool water is rocking, it is advised to remove the POOLGUARD from the pool. Light wind or rain will not effect the POOLGUARD alarm. Another false alarm occurs when the pool owner tries to install the alarm too soon after. swimming. After swimming, the water in the pool will rock or bounce up and down the pool wall for some time depending on the size of the pool and the type of swimming activity. Before installing the alarm, after swimming, the pool must be given time to calm. Time will vary (around 10 to 30 minutes); once the pool owner sees that the pool water is no longer rocking up and down the pool wall, it is time to install the alarm. Certain automatic cleaners may set the POOLGUARD unit off in some cases. If the cleaner head hits the POOLGUARD alarm it may cause it to false alarm. Solutions to this problem are to use your cleaner at night and your alarm during the day. Another option would be to find a place around the pool where the cleaner does not interfere with the alarm. Certain water features such as waterfalls can cause POOLGUARD to false alarm. To avoid this problem do not install the POOLGUARD alarm too close to the water feature. If you are having a problem with any type of water feature call POOLGUARD at 1-800-242-7163. ALARM PLACEIvit: NT The alarm should be on a flat, solid surface for best results. The throat of the unit is designed to work in most pools with an in -wall skimmer. The water level up on the throat is important and should be checked. The sensing throat cannot be less than 2.5 inches in the water, and not more than 5.5 inches into the water. POOLGUARD recommends that the sensing throat be approximately-4 inches in the water. POOLGUARD can be used with a solar cover; however, before removing the cover, the alarm should be taken out so it does not get pulled into the pool. ALARM TESTING Drop something of approximate size, weight and volume of the families smallest child, the farthest point away from the alarm. A four (4) gallon jug of water or 3 one (1) gallon jugs of water tied together are ideal for testing. Remember, when testing you must wait about 15 minutes between tests for the pool to calm. ALARM WILL NOT SOUND CHECK THE CONNECTION BETWEEN THE 9V BATTERY AND THE BATTERY SNAP. If you are testing and POOLGUARD does not alarm, be sure you are testing properly — putting your feet in the pool, splashing with your hands, making waves with a leaf skimmer, or dropping something into the pool that does not have the proper size, weight and volume will not set the POOLGUARD alarm off! Testing is very important and should be done correctly. ALARM HANDLING The POOLGUARD pool unit is an electronic and mechanical device made from a sturdy UV rated PVC material. Do not drop POOLGUARD; like any other appliance, it may break. The POOLGUARD pool unit is water resistant but not waterproof (sun and rain will not hurt the pool unit). Great care should be taken not to let the pool unit fall into the pool. If the pool unit does fall into the pool there are directions on page 2 in this manual on how to dry it out. Always remember to remove the alarm before using your pool. REMOTE RECE'iv"'ER When the unit at the pool alarms, the remote receiver will sound. Maximum Range for the remote is 200 feet from the poolside unit. Avoid placing remote in basements or close to metal walls. Be sure that the red light on the remote is on. Remember the poolside unit must be beeping (alarming) for. the remote to work. If your remote receiver is not getting a clear signal or no signal from the poolside unit, try the following: Before plugging in the power supply, be sure to stretch out the cord; do not leave it tied in a bow as packaged. Your Remote Receiver is similar to a small portable radio. If your remote is not sounding when the poolside unit is sounding —move the remote to different locations and stand back for a few seconds for the remote to pick up the signal. You may only have to move your remote a little to the left or right to bring in the signal —in some cases you might have to move the remote to a different location or another room.

For indoor installations, as an additional measure of safety, Zodiac Pool Systems, Inc. strongly recommends installation of suitable Carbon Monoxide detectors in the vicinity of this appliance and in any adjacent occupied spaces. The heater is designed and manufactured to provide many years of safe and reliable service when installed, operated; and maintained according to the information in this manual and the installation codes referred to throughout. Be sure to read and comply with all wat- ings and cautions. 1.3.1 Spa/Hot Tub Safety Rules A WARNING The following "Safety Rules for Hot Tubs," recommended by the U.S. Consumer Product Safety Commission, should,be observed when using the spa. A WARNING The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous. Consult heater operation and installation instructions for water temperature guidelines before setting temperature. 1. Spa or hot tub water temperature should never exceed 104°F (40°C). One hundred degrees Fahrenheit (100°F [3s,q) is considered safe for a healthy adult. Special caution is recommended for young children. 2. The drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness, and subsequently result in drowning. 3. Pregnant women take note! Soaking in water above 102°F (38.5°C) can cause fetal damage during the first three (3) months of pregnancy (which could result in the birth of a brain - damaged or deformed child). If pregnant women are going to use a spa or hot tub, they should make sure the water temperature is below 100°F (38°C) maximum. 4.The water temperature should always be checked with an accurate thermometer before entering a spa or hot tub. Temperature controls may vary by as much as 1F° (I CO). 5. Persons with a medical history of heart disease, diabetes, circulatory or blood pressure problems should consult their physician before using a hot tub or spa. 6. Persons taking any medication which induces drowsiness (e.g., tranquilizers, antihistamines, or anticoagulants) should not use spas or hot tubs. 7. Prolonged immersion in hot water can induce hyperthermia. Hyperthermia occurs when the internal body temperature reaches a level several degrees above the normal body temperature of 98.6°F (37°C). Symptoms include dizziness, fainting, drowsiness, lethargy, and an increase in the internal body temperature. The effects of hyperthermia include: • Lack of awareness of impending hazard • Failure to perceive heat • Failure to recognize need to leave spa • Physical inability to leave spa • Fetal damage in pregnant women • Unconsciousness resulting in a danger of drowning 1.3.2 Swimming Pool Energy Saving Tips Zodiac Pool Systems, Inc., offers the following, recommendations to help conserve fuel and minimize the cost of operating your pool heater without sacrificing comfort. 1. The American Red Cross® recommends a maximum water temperature of 78OF (260C). Use an accurate pool thermometer. A difference of 4F° (2°C), between 78°F and 82°F (26°C and 28°C), will use as much as 40% more gas. Page 4 Jandye Pro Series, JXi" Gas -Fired Pool & Spa Heater 'I installation & Operation Manual 2. Carefully monitor the water temperature of your pool in the summertime. You can reduce heater usage due to wanner air temperatures. 3. Find the proper setting on the pool heater temperature control and use the Set Point Lockout feature to discourage further adjustments. 4. Set the pump'time clock to start the pump no earlier than 6:00 AM during -the -pool -heating— - season. This is the time when nightly heat loss balances. 5. If the pool is only going to be used on weekends, reduce the heater temperature control setting by 8 or 10 degrees during the week. Reset it to the 78OF (25°C) level a day or so before you plan to use the pool. 6. During the winter or when on vacation for longer than a week, shut down the heater by following the shutdown instructions found on the inside of the heater. 7. Where possible, shelter the pool from prevailing winds with well -trimmed hedges or other landscaping, cabanas, or fencing. 8. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool cover will reduce heat loss, conserve chemicals, and reduce the load on filter systems. 1.4 Warranty This heater is sold with a limited factory warranty. Details are included with this heater. Make all warranty claims to a Zodiac® dealer or directly to the factory. Claims must include the heater serial number and model (this information can be found on the rating plate), installation date, and name of the installer. Shipping costs are not included in the warranty coverage. The warranty does NOT cover damage caused by improper assembly, installation, operation or field modification. Also, damage to the heat exchanger by corrosive water is NOT covered by the warranty. NOTE Keep this manual in a safe place for future reference when inspecting or servicing, heater. 1.5 Certification Codes and Standards The heater is design -certified by CSA (Canadian Standards Association) compliant with the latest edition of the Standard for Gas Fired Pool Heaters, ANSI® Z21.56 in the USA and CSA 4.7 in Canada. All Jandy Pro Series heaters must be installed in accordance with the local building and installation codes as per the utility or Authority Having Jurisdiction (AHJ). In the absence of local codes, refer to the latest edition of the following national codes for installation: 1. In the United States, the National Fuel Gas Code, NFPA® 54/ANSI M23.1. Pay particular attention to the chapter addressing Venting ofEquipment. 2. In Canada, the Natural Gas and Propane Installation Code, CAN/CSA-13149.1. Minimum combustion air requirements MUST be followed for proper and safe operation. The _Jandy Pro Series JXi heater may not operate properly when installed with only the minimum combustion air openings allowed in CAN/ CSA-B149.1. The JXi pool and spa heaters meet or exceed the requirements of energy conservation regulations, such as those in California, Hawaii, New York, Oregon and other states that have disallowed the use of continuously lit pilot type ignition sources. In addition, the natural gas models of this heater comply with the California South Coast Air Quality Management District's (SCAQMD) Rule 1146.2 for Nitrogen Oxide (NOx) emissions. Any changes to the heater, gas controls, air orifice, gas orifices, wiring, draft diverter, or improper installation may void the warranty. If change is required to any of the above, consult the factory. 1.6 General Operation Description In the JXi heater, the blower draws air and fuel through specially designed orifices for both air and gas, then delivers the precise mixture to the bumer located inside the combustion chamber. The combustion chamber is completely sealed and contains the heat exchanger, which surrounds the burner. Once combustion gases pass through the heat exchanger, the flow is directed through an exhaust duct located on the side of the combustion chamber, where it vents to the atmosphere. 1.7 Safety Controls The JXi heater is equipped with the following safety controls to protect internal components and prolong the life of the heater. Air Flow switch The air flow switch monitors the vacuum (negative pressure) within the blower housing. The air flow switch is factory set and the ignition module will not operate unless the air pressure switch and all 'safety switches are satisfied. Water Pressure Switch Operating the heater without sufficient water flow may severely damage the heater. If water flow to the heater is restricted, the water pressure switch prevents the bumer from firing. The control panel will display an error message to indicate water flow is insufficient. JandyO Pro Series, JXi" Gas -Fired Pool & Spa Heater I Installation & Operation Manual Page 5 NOTE. If the heater is installed below the level of the pool,(or more than two feet above the pool level), the pressure switch setting must be adjusted. See Section 5.4 Adjusting the Water Pressure Switch for guidelines. Water Temperature Control All heater models are equipped with an electronic control which senses water temperature by means of a thermistor and controls heater operation to bring the water to the temperature selected. It has an option for two (2) separate thermostat settings which are typically used to set pool and spa temperatures. Ignition Control The ignition control provides energy for ignition of the air/ gas mixture, monitors the flame and controls the gas valve. When the temperature control calls for heat, the ignition control initiates the start-up process by first purging the combustion chamber gases. The ignition control will then energize the igniter and open the gas valve when the igniter surface is sufficiently hot. During the start-up Process and after ignition, the ignition control system is continually monitoring the flame condition. If the control senses an unstable flame it will close the gas valve as a safety precaution. Section 2. Installation Requirements 2.1 Introduction Install the JXi in accordance with the procedures in this manual, local codes and ordinances, and in accordance with the latest edition of the appropriate national code. See Section 1.5 for certification codes and standards. All gas -fired products require correct installation to assure safe operation. The requirements for pool heaters include the following: • Field assembly (if required) Appropriate site location (clearances) and flooring (see Section 2.6) • sufficient combustion and ventilation air • Properly sized gas meter and piping • Proper electrical wiring (if required) • Adequate water flow This manual provides the information needed to meet these requirements. Review all applications and installation procedures before continuing the installation. See Section 2.7 for NOTE on operating the heater in areas with below freezing conditions. 2.2 Materials Installer Must Provide • The correct size gas pipe to supply gas from gas meter to heater (see Section 4.1). • Gas shut-off valve to be installed in gas line outside of the heaterjacket • Manual gas shut off valve must be installed in an accessible location, within 6' upstream of heater. • A suitable gas union joint to connect heater to gas line outside of heater. • Plumbing materials for providing sediment trap (drip leg) in gas line between the manual gas valve and heater (see Section 4.1). • 120 VAC or 240 VAC power supply. (Ajunct on box is not needed at the heater, connections are made inside of the heaterjacket) INDOOR INSTALLATIONS: Factory authorized vent pipe or elbows sized for indoor installations (US) and/or outdoor shelter installations (Canada).

Electncal'SuPP1Y :....._.... . 120 VAC • 240 VAC (factory setting) ;High Altitude • Appliances are normally de -rated when installed at high elevation. This is not necessary with the JXi heater because it has a special ventud-type combustion system which self -compensates for changes in barometric pressure. Air flow through the blower inlet pulls the correct flow of gas into the burner regardless of air density. Proper combustion and high efficiency are assured without special adjustment or changes to the heater. 1. Gas Valve - The gas valve controls gas flow into the burner. It enables flow only when the temperature control requires heat and only if all safety controls enable operation. It is also a negative pressure regulator, where it maintains a gas pressure of 0.2" WC, below the the air pressure at the blower inlet. It regulates the gas pressure to 0,2" WC less than the air pressure at the blower inlet. This is necessary for proper operation of the burner system and cannot be accomplished with common (positive pressure) gas valves. 2. Combustion Blower and Air Orifice — The blower pulls air and fuel gas in through their respective orifices and mixes the two gases before forcing the fuel/air mixture through the burner for combustion. During normal operation the fan will tum on before flame initiation to ensure that the combustion chamber is clear before the igniter is energized. Additionally, the fan will run after the flame is extinguished in order to clear the combustion chamber of exhaust gas. 3. Pool/Spa Water Temperature Control -The JXi heater models are equipped with an electronic control, which senses water temperature by means of a thermistor and controls heater operation to attain and maintain the water according to the temperature selected. It has an option for two (2) separate thermostat settings, which are typically used to set pool and spa temperatures. 4. Ignition Control - The ignition control provides energy for ignition of the air/gas mixture, monitors the flame and controls the gas valve. When the temperature control calls for heat, the ignition control provides a pre -purge of the combustion chamber. Once the pre -purge is complete the ignition control then applies electrical power to a hot surface igniter. When the igniter attains sufficient temperature, the ignition control opens the gas valve. Immediately after ignition, the control system will look for characteristics of a stable flame and de -energize the igniter. If flame is not detected shortly after opening the gas valve the control system will close the valve to prevent further gas release. The ignition control will attempt to start 2 more times before an ignition fault is displayed. 5. Igniter - The hot -surface igniter is constructed of a ceramic material that attains a temperature great enough to ignite the air/fuel mixture, when an electric current is applied. Jandlp Pro Series, JXi" Gas -Fred Pool & Spa Heater I Installation & Operation Manual Page 7 6. High Limit Switches = Two (2) limit switches - the blower housing. This switch verifies that air one at the heat exchanger first pass (I35OF/57°C) is flowing through the combustion system by and one at the heat exchanger outlet (150°F/650C) sensing pressure. It shuts off the heater if air flow Prevent water of excessive temperatures from is inadequate. being discharged from the heater. If either switch . senses excessive temperature, the gas valve will 2.6 Dimensions close and combustion will stop. 7. NOTE 8. Water Pressure Switch - Operating the heater without sufficient water flow may severely damage the heater. This control senses whether or not water is available to the heater by measuring back pressure at the header inlet. If the pool water pump fails or the water filter is blocked, the pressure switch prevents operation of the bumer. The display will indicate a no now fault to alert YOU that water pressure is insufficient. If the heater is installed below the surface level of the pool,(or more than two feet above the pool level), the Pressure switch setting must be adjusted. See section 5.4 Adjusting the Water Pressure Switch. Vent Temperature Limit (240°C/4640F)- This is a single use switch, which detects abnormal temperatures in the vent system. It is mounted to the exhaust duct. Excessive temperatures will cause the switch to open. Excessive temperatures can be caused by inadequate water flow or a compromised heat exchanger. The vent temperature limit switch will open the safety circuit which shuts ofl'the gas valve and shuts. down the heater. If this limit is Activated/tripped, the heater cannot be safely operated without first determining the cause and without replacing the limit switch with an exact replacement. 9. Air Pressure Switch - The air.pressure switch monitors the vacuum (negative pressure) within oavusrsine See Figure I for exterior dimensions and dimensions to critical connections. 2.6 Clearances In both indoor installations (US) and outdoor shelter installations (Canada), the heater must be placed to provide clearances on all sides for maintenance and inspection, as well as maintain minimum distances from combustible surfaces. NOTE Clearances are manufacturer's tested values. These are given as minimum values.

Check specifications in Section 2.3 for appropriate vent connection size (Category I)7 water connections are provided on the right side of the heater but can be changed to the left side by rotating the heater 180 degrees, so the water manifold is on the left, then rotating the top panel so that the control panel faces the operator. NOTE: If the heater is to be operated in below freezing conditions it should be installed in a protected outdoor shelter (see Section 2.8.3). 2.8 Location Requirements CAUTION When pool equipment is located below the pool surface, a leak from any component can cause large scale water loss or flooding. Zodiac Pool Systems, Inc., cannot be responsible for such water loss or flooding or resulting damage. Location of the heater below or above the pool water level affects operation of its water pressure switch. See sections on water piping and heater start-up for more information. All criteria given in the following sections reflect minimum clearances as stated in the national standards. However, each installation must also be evaluated, taking into account the prevailing local conditions such as wind speed and direction, proximity and height of walls that may block ventilation, and proximity to public access areas. 2.8.1 Flooring The heater must be installed on a level, solid, and firm surface or platform. Although it is always advisable to install the heater on a non-combustible surface, the JXi- series has been CSA-certified for installation on solid, firm, and level combustible surfaces. . 2.8.2 Outdoor Installation The heater is factory configured for outdoor installation. A WARNING United States Do not Install the heater with the lop of the vent assembly within 4 feet (1.22 m) horizontally.4 feet (1.22 m) below or less than 1 it (300 mm) above of any opening into a building. Local codes and Installa- tion requirements may vary. Canada Do not install the heater with the top of the vent asembly within 10 feet (3.05 m) of any opening Into a building. Local codes and Instal- lation requirements may vary. • Locate the heater on a level surface in an open, unroofed area. If the heater is to be installed inside a contained area, refer to venting requirements, Section 2.8.3. • Do not install the heater under a deck. • Do not locate the heater below or adjacent to any doors, glass openings, louvers, grills, etc., which connect in any way with an inhabited area of a building, even though the access might be through another structure (e.g., a garage or utility room). • In Canada, install the heater so that the top of the vent is at least 10 feet (3.0 m) from any building opening. See Figure 3. JandyOPro Series, J)G"Gas-Fired Pool &Spa Heater I Installation& Operation Manual Page 9 • The top surface of the heater must be at least 3 feet (0.9 m) above any forced air inlet, or intake ducts located within 10 feet (3.0 m) horizontally. • The area under an overhang must be open on three sides to prevent combustion gases from being diverted into living areas through doors, windows, or gravity inlets. • In the United States install the heater so that there is at least a three (3) foot (1 m) clearance between the bottom of the overhang to the top of the heater exhaust vent. • If the heater is installed close to a structure, protect it from rain water runoff with rain gutters on the roof or other measures. • Do not locate the heater near irrigation sprinkler systems that could spray water on it. Water from sprinklers can damage controls and electronic components. • Be sure to divert rain water runoff away from heater Figure 3. _ Outdoor Heater Installation Outdoor Installations in Florida: Due to the high risk of extreme weather conditions in Florida, the heater is required to be securely fastened to the equipment pad (see Figure 4) to meet the applicable requirements of the Florida Building Code.

Be sure to consult local codes and installation requirements as somejudsdications may have varying and more stringent requirements. Canada Do not install the heater with the top of the vent asembly within 10 feet (3 m) of any opening into a building. Be sure to consult local codes and installation requirements as some.judsdications may have varying and more stringent requirements. The heater is CSA design -certified for indoor installations in the US and for outdoor shelter installations in Canada. To install for outdoor shelter area, you will need to remove the vent housing and the exhaust grate. When pool equipment is installed indoors, appropriate containment and drain should be provided to prevent property damage in the event of equipment leaks. NOTE: An outdoor shelter is an unoccupied enclosure which does not communicate directly with occupied areas. All outdoor shelter installations (Canada only) must have uninterrupted openings to outside air for combustion and ventilation. The installation must be in accordance with the latest edition of CAN/CSA B 149.1. Zodiac Pool Systems, Inc., does not recommend outdoor Page 10 111qjjjgagjjTggNpli, Jandy° Pro Series, JW Gas -Fired Pool & Spa Heater I Installation & Operation Manual shelter installations that depend on internal air for combustion (see Table 1). Due to the higher risks and hazards of Liquid Propane (LP) gas, Zodiac does not encourage installation of LP gas heaters indoors. Please be sure to refer to section 4.2 for additional precautions that must be considered for LP gas. Section 3. Venting 3.1 Combustion Air Supply As outlined in the latest edition ofANSIo standard Z223.1 (NFPA® 54), the heater location must be properly vented to provide sufficient air supply for proper combustion and ventilation of the surrounding area. In general, these requirements specify that the room in which a heater is installed should be provided with two permanent air supply openings: • one within 12 inches (305 min) of the ceiling • one within 12 inches (305 mm) of the floor All indoor installations must have openings to outside air for combustion, ventilation, and dilution of flue gases from inside the building. Do not, under any circumstances, install this product in an indoor location which does not, provide combustion air to the appliance from outside the building. In addition, the heater must be completely isolated and protected from any source of corrosive chemical fumes such as those emitted by trichlorethylene, perchloroethylene, chlorine, etc. A WARNING Do not store any chemicals, cleaners, or other cor- rosive material near combustion air openings or in the room. Avoid locating appliance vents in the vicinity of combustion air openings. Failure to prevent corrosive materials from mixing with combustion air can result in reduced heater life and unsafe heater operation.

Air Openings to Outside NOTE: If using screens andfor metal louvers, compensate by adding 50% additional area to each opening. If using wood louvers, each opening must be at least four times the area indicated in the table above. For special conditions, refer to Section 9.3.3.1 NFPA 54 ANSI Z223. The information in Table 1 is not applicable in installations where exhaust fans or blowers of any type are used. Consult a Professional Engineer.(P.E.) to ensure that installations where exhaust fans or blowers are used are designed and installed in accordance with all applicable local and national installation codes. Outside Air Supply: When combustion air is supplied directly through an outside wall, each opening should have a minimum free area of 1 square inch per 4,000 BTU/h (1.2kW) input of the total input rating of all appliances in the enclosed area. If air is provided through horizontal ducts, each opening and duct must provide 1 square inch of flow area for each 2000 BTU/h (0.6 kW). These requirements are summarized in Table 1. Exhaust Fans or Vents: Any equipment which exhausts air from the room where the heater is installed can deplete the combustion air supply or reverse the natural draft action of the venting system. This could cause flue products to accumulate in the room. Additional air must be supplied to compensate for such exhaust. The information in Table 1 is not applicable in installations where exhaust fans or blowers of any type are used. Such installations must be designed by a Professional Engineer (P.E.). 3.2 Exhaust Venting When converted to indoor and outdoor shelter venting configuration, the M has a flue collar for attachment to the venting for category I vertical venting and category Jand? Pro Series, J)aw Gas -Fred Pool & Spa Heater I Installation & Operation Manual Page 11 III vertical and horizontal venting. The only correct procedure for vent pipe sizing is to do so in accordance with Table 2 (Section 3.3.2 of this manual) and the applicable installation code as stated in the following warning and Table 13.1(a) and 13.1(b) per NFPA 54 for category I and Table 3 for Category III. A WARNING Vent pipe materials, sizing, and installation must be as required by the National Fuel Gas Code NFPA 54/ ANSI Z223.1 or the Canadian Installation Codes for Gas Appliances CAN/CSA-B149.1. Undersized pipe can result in inadequate venting and oversize pipe can result in vent condensation. Improper selection of vent pipe material, incorrect sizing of the pipe, and misinstallation of vent piping can result in release of combustion products to the indoors. This can cause serious injury or death by Carbon Monoxide poisoning or asphyxiation. Note that with horizontal Category III type vent installations, the venting diameter is four (4) inches and AL29-4C®stainless steel. The JXi flue collar fits 4-inch vent pipe and elbows. See Section 3.3.1 for procedure to connect vent pipe and elbows. 3.3 Vent Pipe Sizing and Installation The JXf may be installed with venting as a Category I or Category III appliance. • Category I: A Category I appliance is a vented appliance that operates with a non -positive vent static pressure and with a vent gas temperature that avoids excessive condensate production in the vent. Category I installations are vented vertically and terminate at the roof. • Category III: A Category III appliance is a vented appliance that operates with a positive vent static pressure and with a vent gas temperature that avoids excessive condensate production in the vent. Category III installations can be vented via a side wall. In all installations (Category I and Category III): • Avoid terminating heater vents near air conditioning or air supply fans. Fans can pick up exhaust flue products from the heater and return them inside the building, creating a possible carbon monoxide or other health hazard. • Selection of vent pipe type and material must be carefully considered depending on the type of installation. Zodiac strongly recommends using high quality vent pipe materials, which are corrosion resistant and suitable for the specific installation being considered Do not locate the vent terminal where flue products could strike against building materials and cause degradation. Vent opening should be well away from trees or other obstructions that would prevent free air flow to and from vent terminal. Do not terminate the vent under decks, stairways, or car ports. 3.3.1 Vent Pipe or Elbow Increaser Installation (Category I and Category III) Remove the exhaust body. 2.

Following the vent connector's manufacturer instructions attach the vent pipe to the increaser and further secure them with sheet metal screws. Before connecting, wet a clean cloth or paper towel with rubbing alcohol and wipe the socket of the vent body. Dry with a different clean cloth. Vent piping must be adequately supported with no low spots or sagging that could allow condensate to collect. The heater must not be used to support the vent pipe. Horizontal runs must be sloped upwards away from the heater to a vent terminal at a minimum of 1/4 " per horizontal foot (2 cm/m). 4. Install the vent pipe so it can expand and contract freely with temperature changes. Note: Do not run the heater vent into a common vent with any other appliance. 3.3.3 Vertical or Horizontal Venting (Category 111) When the installation requires horizontal venting in excess of what is allowed for Category I installations or calls for horizontal discharge, the JXi may be installed with a Category III venting system. Vent the heater either vertically or horizontally using A129-4C® stainless steel components. Consult manufacturers such as Z-Flex® or Heat Fab® to obtain approved components. Venting materials must comply with UL®1738 for Category III, Special Gas Vent. In Canada, the venting materials must be ULC S636 compliant. Vent piping must be adequately supported with no low spots or sagging that could allow condensate to collect. The heater must not be used to support the vent pipe. Horizontal runs must be sloped upwards away from the heater to a vent terminal at a minimum of 1/4 inch per horizontal foot (2 cm/m). It is recommended that vent runs over 18 feet be insulated to reduce condensation and/or use a condensate trap in the vent run close to the heater, especially in certain cold climate installations. See Table 3 for recommended vent size and run lengths without elbows. For each elbow installed, reduce the run length by 12 feet (3.7m) Heater Size Vent Size Special Gas Vent Length (vertical or horizontal) in feet (metres) 200 4" (10cm) TBD (m) 260 4" (10cm) 50' (15m) 330 4" (10cm) TBD (m) 400 4" (10cm) 50' (15m) Table 3.

In addition, always consult your local installation codes. Some local installation codes may have requirements that exceed those of the the national codes. The product must be installed in accordance with the codes being enforced by the local Authority Having Jurisdiction (AHJ). See Figure 9 for side wall vent terminations. IMPORTANT NOTE In the Commonwealth of Massachusetts, additional requirements, covered In document CMR 248 5.00, which supersede some of the requirements of ANSI Z223.1 (NFPA 54) apply to Side Wall Horizontally Vented appliances. If installing this product using an approved side -wall horizontal vent system in the Commonwealth of Massachusetts, be sure to adhere to these additional requirements. These requirements include verbiage that says that the property owner is to ensure that Carbon Monoxide Detectors are installed in the vicinity of the appliance and also on all levels of the dwelling in which the appliance is, installed. For further instructions, contact Zodiac Pool Systems, Inc., Technical Support Department at 800.822.7933 (in Canada: 888.647.4004) 1. Install the vent connector or elbow (see Section 3.3.1). 2. Install the vent pipe so it can expand and contract freely with temperature changes. Before connecting, wet a clean cloth or paper towel with rubbing alcohol and wipe the socket of the vent body. 3. Follow installation instructions from the manufacturer of the special gas vent components. A WARNING Incorrect design and installation of heater vents and ducts can result in personal injury, damage to property, or death. To avoid such hazards, the heater must be installed only by a qualified professional service technician. JandyO Pro Series, JIG" Gas -Fred Pool & Spa Heater I Installation & Operation Manual Page 15 Precautions Against Common Venting: Seek the assistance of a Registered Professional Engineer for proper design of a common venting system. Zodiac Pool Systems, Inc. does not recommend using a common vent to vent multiple appliances through a common duct. However, if no other option is deemed available by the installer, each appliance must have its own vent temperature limit switch. All vent limit switches must be wired in series so as to prevent any appliance from firing in the event of a blocked vent. An outside draft inducer must be installed to pull and create negative pressure in the vent system. Refer to ANSI® Z223.1 or in Canada CAN/CSA B 149.1 for more information on common venting multiple appliances. Do not connect vent systems of different categories to the same venting A WARNING Improper installation or maintenance can cause nausea or asphyxiation from carbon monoxide in flue gases which could result in severe injury, or death. For indoor installations, as an additional measure of safety, Zodiac Pool Systems, Inc. strongly recommends installation of suitable Carbon Monoxide detectors in the vicinity of this appliance and in any adjacent occupied spaces. 3.3.4 Inspection and Replacement of Existing Vent System with New Components When replacing an existing pool heater with the JXi, it is recommended that a new appropriate venting system is installed with the new heater. However, if the existing venting system must be used, be sure to carefully inspect the existing system to ensure that it is in good condition and appropriate for the JXi heater. Replace any parts that are not in serviceable condition before completing the installation. Section 4. Gas Connections 4.1 Install Piping and Check Gas Supply Gas piping installation must be in accordance with the latest edition ofANSI Z223.1 and all local codes. In Canada, the installation must be in accordance with CAN/ CSA B149.1 and all local codes that apply. The heater must be isolated from the gas supply piping system by closing the individual manual shut off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psi (3.5kPa). The heater and its individual shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa). A WARNING The JXi pool and spa heaters are designed for use with either natural gas or LP gas. Check the rating plate on the front of the combustion chamber to be sure that the heater is designed to use the type of gas being supplied. DO NOT ATTEMPT TO CONVERT THIS HEATER FOR USE WITH ANY OTHER TYPE OF FUEL OTHER THAN THE FUEL TYPE FOR WHICH IT WAS CONFIGURED AT THE FACTORY AND WHICH IS MARKED ON THE NAMEPLATE. . . CAUTION Permanent damage to the gas valve will occur if the installation procedures are not followed correctly. 1. Refer to Table 4 for correct gas inlet piping length from the gas meter to the heater. When sizing gas lines, calculate three (3) additional feet of straight pipe for every elbow used. _Distance+from Gas Meter Heater 0-50feet 50-100feet 100-200feet Size (0-15 m) (15-30 m) (30.60 m) in. mm in. mm in. mm 200 1 25 1-1/4 32 1-1/4 32 260 1-1/4 32 1-1/4 32 1-1/4 32 330 1-114 32 1-1/4 32 1-1/2 38 400 1 1-1/4 32 1 1-1/2 38 1-1/2 38 Notes: Numbers are for natural gas.

For LP gas, reduce pipe diameter by one size, but maintain a minimum 314 inch diameter. Check supply pressure and local code requirements before proceeding with installation. Consider pipe fittings when determining gas pipe sizing. Table shows the minimum supply gas pipe size required. Larger pipe size can be used if required by local code or if desired. It is critical that the incoming gas supply pressure at the heater is within the maximum and minimum pressure requirements. If the range of acceptable supply pressure is not provided, the gas supply system to the heater must be modified to meet pressure requirements. Table 4. Supply Gas Pipe Size Requirements* 2. Check the gas meter to make sure it will supply enough gas to the heater and any other appliances using the same heater. NOTE: The gas line from the meter is usually larger than the gas valve. Therefore, you will need to reduce connecting pipe as necessary. Make this reduction as close to the heater as possible. 3. Install a manual gas shutoff valve for service and safety.

Gas Pressure Natural Propane Inches W.C. Maximum inlet 10.5 14 Minimum inlet 4 4 Gas Offset — 0.2 — 0.2 Notes: All readings must be taken while the heater is operating. Any adjustments or readings made while the heater is off will result in poor performance and problems. Table 5. Gas Supply Pressure Requirements 6. If the gas supply pressure is less than required, check for undersized pipe between the meter and the heaters, a restrictive fitting, or an undersized gas meter. 7. Before operating the heater, test the complete gas supply system and all connections for leaks using a soap solution. Do not use an open flame to test for leaks. CAUTION Some leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing. 4.2 Special Precautions for LP Gas Under the same environmental conditions, liquid propane (LP) gas is more dense than air and will more readily collect in enclosed areas if there is not adequate ventilation. It is not recommended to install LP gas heaters in enclosed areas such as pits. Locate heaters a safe distance from LP gas cylinders and filling equipment: Consult the National Fuel Gas Code (NFPA® 54/ANSI® Z223.1, latest edition), the Liquefied Petroleum Gas Code (NFPA 58, latest edition), the Natural Gas and Propane Installation Code in Canada (CAN/CSA B 149.1, latest edition), and any other local codes and fire protection authorities about specific installation restrictions in your area. For ALL installations the combustion air openings requirements and NFPA54 / ANSI Z223.1 MUST be followed for safe and proper operation. Section 5.

Locating the heater above or below the pool water surface can also affect operation of the switch. NOTE: When pool equipment is located below the pool surface, Zodiac Pool Systems, Inc. is not responsible for any large scale water loss, flooding or damage caused by a leak. The heater must be protected from back -siphoning of water, which can result in dry starts. If there is any chance of back -siphoning, provide a check valve between the pool and the filter pump inlet. 5.2 Pump Sizing The internal flow bypass within the heater manifold will accommodate flows delivered to the heater from a minimum of 30 gallons per minute (gpm) to a maximum flow of 120 gpm, depending on the heater model. A manual bypass valve should be installed when the pump flow exceeds 120 gpm. To install a manual bypass valve: 1. Connect ball valve valve between water inlet and outlet (Figure 13). Heater IN OUT W Ball Valve Figure 13. Install Manual Bypass Valve IMPORTANT The system water pump must be capable of providing no less than 30 gpm of flow through the heater. Flow rates of less than 30 gpm may cause nuisance operation causing the heater to turn off or damage to the heater. 2. Adjust the valve to bring the flow rate within the acceptable range (see Table 6).

Remove the valve handle to avoid tampering. Pump Sizing for New Pool Construction: When sizing a pump for the system, the head loss for all system components must be added together when determining the design flow rate. Component "Head Loss at Flow" curves are available from equipment manufacturers. NOTE: In order to properly establish head loss at flow for a filter, remember that a "dirty" filter can typically add 10 psi of additional head loss (23 extra feet of head). This must be considered when sizing a pump for a new pool system. Pump Sizing for Replacement in an Existing Pool: If the JXi heater replaces a different model of heater, determine if the existing pump is capable of providing the minimum flow of no less than 30 gpm indicated in Table 6 for the specific model. JXi heaters are high efficiency heaters. Heaters typical of this construction may have higher head loss characteristics than the one being replaced. IMPORTANT Heater failure due to insufficient water flow is not covered under warranty. See measurements in the Head Loss Chart, Figure 14.

Head Loss Chart 6.3 Plumbing Connections The heater has a standard 2 inch water header and coupling design. With this feature, only nominal two inch PVC or CPVC may be connected to the heater. However, by installing the appropriate pipe adapters and two (2) short pieces of two-inch plastic pipe (supplied by the installer), any size existing pipe may be fitted to the heater. Optional Water Inlet Piping The water inlet can be piped in one of two possible configurations. The heater comes with a Zodiac® Sweep Elbow for increased hydraulic performance and efficiency. The sweep elbow also provides the advantage of its exclusive interface with the Zodiac AquaLink' RS temperature sensor. The sweep elbow may be installed in the top inlet connection, and the cap and plug with O-ring installed to close off the unused side port (see Figure 15). This configuration may be preferred for Versa Plumb® piping to mating components Figure 16. Top Inlet Piping Using the Versa Nlumn Sweep Elbow Jandy° Pro Series, J)Q' Gas -Fired Pool & Spa Heater I Installation & Operation Manual Page 19 Optionally, the top inlet opening may be capped with the union nut and cap, and plug with O-ring provided, then the water inlet port on the side directly above the outlet port may be used. (See Figure 16.) rrgure 7b. optional Side Inlet Piping A WARNING To avoid an electrical shock hazard, which can result in serious injury or death, ensure that all electrical power to the system is turned off before approach- ing, inspecting or troubleshooting any leaking valves or plumbing that may have caused other electrical devices in the surrounding area to.get wet. A WARNING Follow all filter manufacturer's instructions. NEVER attempt to assemble, disassemble or adjust the filter when there is pressurized air in the system. Starting the pump while there is any pressurized air in the system can cause the filter lid to be blown off, which can cause death, serious personal injury or property damage. To install the Sweep Elbow: Clean the cut ends of the pipe and both ends of the sweep elbow(s) with an appropriate NSF® approved All Purpose cleaner/primer. Glue the sweep elbow(s) onto the cut pipe ends using an appropriate All Purpose NSF approved adhesive/ glue. NOTE Zodiac Pool Systems, Inc. recommends Weld -On® 724TM PVC to CPVC Cement to glue Schedule 40 PVC. 2. After the glue is cured, close the pressure relief valve on top of the filter. 3. Return all valves to their operating positions. 4. Turn on power to the heater. 5. Turn on the pump to check for water leaks. 6. Restore the gas supply to the heater. 7. Start the system and check for proper water flow. 5.4 Water Pressure Switch Adjustment CAUTION The water pressure switch should be adjusted to turn the heater off when the pump is off. Setting the switch to close at too low flow can damage the appliance. Adjust the switch to turn the heater off, not on. The pressure switch is preset at the factory for activation at 2 psi (14 kPa). If the heater is installed below the surface level of the pool, more than two feet above the pool level, or any time the pressure is measured at 1 psi or greater with the system pump off the pressure switch setting must be adjusted. Location of the heater above or below the pool water surface can also affect the operation of the switch. The factory installed switch can accommodate elevations not exceeding 6 feet above the pool water surface or 11 feet below pool water surface. If the heater water connections are outside this range Consult your. local Zodiac representative for recommendations. Make sure the pool filter is clean before making any pressure switch adjustment. A dirty filter will restrict the water flow and the pressure switch cannot be adjusted properly. To adjust the water pressure switch: NOTE: It is recommended that a Pressure Release Valve (PRV) be installed prior to taking any of the steps below. See section 6.7 1. Set the heater control to the "OFF" mode. 2. Remove the header side panel to access the water pressure switch. 3. Start the filter pump and confirm by means of a voltmeter that the pressure switch closes (if the switch fails to close, replace it with a switch that has a lower minimum setting). 4. Set the heater control to either POOL or SPA. Heater should start. 5. With your fingers, turn the adjustment sprocket very slowly clockwise until the heater goes off. (See Figure 17.) Page 20 . Jandy° Pro Series, JW Gas -Fred Pool & Spa Heater 'I, -installation & Operation Manual 0 Slowly turn adjusje� sprocket clockwi heater goes off Figure 17. Adjust Pressure Switch 6. Slowly turn the pressure switch adjustment sprocket counterclockwise one -quarter turn. The heater should come back on. 7. Check the adjustment by turning the filter pump OFF. The burners should shut off immediately. If they do not, restart the filter pump and repeat Steps 6 and 7. Check the adjustment again. 8. Return the pool temperature control to the desired temperature. It may be necessary to repeat these steps to get a proper setting. The switch must be set so that the heater will not fire unless the pump is running. If a proper setting cannot be reached, contact the factory service department. 5.5 Check Valve Installation When any equipment is located below the surface of the pool or spa, back -siphoning can occur, which is when the pump stops and a pressure -suction differential is created. Check valves should be installed in the piping system to isolate the equipment from the pool or spa if there is any chance of back -siphoning. Always install a check valve if there is a chemical feeder installed in the system (see Section 5.8). A WARNING A check valve can interfere with the proper operation of certain Suction Vacuum Release System (SVRS) products. To avoid possible entrapment hazard, serious injury, or death, make sure to review the operation/owners manual of your particular SVRS product before installing the check valve. Do not install any shutoff valve in the piping between the heater outlet and the pool, unless it is being used as a diverter valve. Always use care when installing chemical feeders so that there is no back -siphoning of chemical into the heater, filters, or pump. Make sure the feeder outlet line is downstream of the heater and a positive seal noncorrosive check valve is installed between the feeder and the heater. 5.6 Reversing the Water Connections The JXi heater is shipped with water connections on the right side, but the top panel can be rotated to adapt to left - side -water connections. This procedure involves turning the heater and then removing and rotating the top panel of the heater. The heater wiring procedure must be done only by a trained service technician. 5.7 Pressure Relief Valve Installation A pressure relief valve (PRV) is recommended in all installations, and is mandatory in any installation in which the water flow can be restricted between the heater outlet and the pool/spa. A pressure relief valve is not supplied with the JXi heater. However, it is recommended that a pressure relief valve be installed and may even be required by local codes. Be sure to check any applicable installation codes in your area to determine whether a pressure relief valve is required. The maximum working pressure of this heater is 50 psi. Be sure to take into consideration the maximum allowable pressure of the'other components in the system when selecting a PRV. Any pressure relief valve installed must comply with provisions of the standard described in ANSI" Z21.22 for the United Sates or CSA 4A in Canada. To install a pressure relief valve: 1. Locate the threaded boss on the outlet port of the in/out header (beside the "out" arrow). See Figure 18. 2. Note the dimple at the center of the.blind bottom of the boss. Using the dimple to center the drill bit, drill a 1/4" diameter hole through the bottom of the boss, taking care not to damage he surrounding plastic threads. (TIP: Drilling a 1/8" diameter hole first will help prevent thread damage.) A WARNING Drilling through plastic can often cause the drill bit to 'grab', causing the drill motor to twist in your hand. Hold drill firmly to avoid potential injury. NOTE: The fittings must be installed immediately after the outlet with no valves or other components inbetween. The pressure relief valve must be installed at the outlet port Do not install at either of the header inlet ports. 3. Install a brass 3/8 NPT x 3/8 NPT x 3" long pipe nipple into the boss, using 5 to 6 wraps of Teflon® tape on the threaded end. Do not overtighten. See Figure 18. Jandl/' Pro Series, M" Gas -Fired Pool & Spa Heater I Iristallation & Operation Manual&IJJJJ�Page 21 CAUTION Use Teflon® tape only on the threads of the pipe nipple attachment to the plastic header. Do not use any pipe compound or pipe dope on the threads or any partthat comes into contact with the plastic headers. These compounds may damage the header over a period of time. "Wt III Heater Water Out 314-inch NPT NPT 2-In h NPT NPT reducer Tee nipple Figure 18. Pressure Relief Valve Installation 4. Wrap 5 or 6 turns of Teflon tape on the end of the pipe nipple and install a 3/8 NPT brass elbow while holding the pipe nipple from rotating. Orient the elbow to point straight up. See Figure 18. 5. Install a brass 3/4 NPT female to a 3/8 NPT male pipe adapter to the elbow using 5-6 turns of Teflon tape on the male end of the adapter. See Figure IS. 6. Install the pressure relief valve on the elbow. Use 5-6 turns of Teflon tape on the male end of the valve. Install the pressure relief valve so it is vertical. See Figure 18. 7. Install a drain pipe from the pressure relief valve outlet to a safe area. This is a precaution to prevent the possibility of personal injury or property damage in the event scalding water is discharged from the pressure relief valve. Install the drain pipe so that there is no trapped or standing water in the piping. Drain piping must be facing down, terminating with a threadless nipple, no less than 6" from floor. It must be open with no reducers or shut-off valves or other restrictions. NOTE: To ensure the continued proper operation of the pressure relief valve, the valve should be tested once a year. To test, lift the lever with the circulation system running to ensure that water will pass through. When the lever is down, there should be no leaks from the outlet: 5.8 Auxiliary Components, Chlorinators, Ozone Generators, and Sanitizing Chemicals The JXi heater is manufactured with materials that are not compatible with high concentrations of ozone, chlorine, bromine, or other sanitizing chemicals. Heater damage caused by excessive chemicals or improper ozonization is not covered by the Zodiac Pool Systems, Inc., warranty. Be sure to adhere to the following: • When ozone is injected upstream of the heater, install an offgas mixing chamber, or an ozone bypass system between the heater and the ozone injector to prevent ozone and air from entering the heater. • When chemical feeders are used, plumb the feeder downstream of the heater and install an in -line check valve between the heater and the feeder (a minimum of 18 inch is required between the heater and the check valve). • Wire any electrical chemical feeder so that it cannot operate unless the filter pump is running. If the feeder has an independent clock control, synchronize it with the filter clock. Never deposit chemicals directly in the pool skimmer. Section 6. Electrical Connections A WARNING ELECTRICAL SHOCK HAZARD. This heater contains wiring that carries high voltage. Contact with these wires may result in severe injury or death. CAUTION Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dan- gerous operation. Verify proper operation after servicing. 6.1 General Information Wiring connections must be made exactly as shown in the wiring diagram found on the inside of the heater door.

Electrical System Service Access 6.3 Main Power Electrical wiring must be in accordance with the latest edition of the National Electric Code® (NEC®), ANSI Y National Fire Protection Association® (NFPA") 70, or in Canada, the Canadian Electrical Code (CSA® C22.1) unless local code requirements indicate otherwise. The heater comes factory -wired intended for use with 240 Volt, 60 Hz AC field electrical supply. To use 120 Volt, 60 Hz AC requires changing the position of the voltage selector board on the power distribution board. This must be done by a certified electrician only, as with all wiring. Be sure that the power source to the heater is turned off or disconnected before servicing. NOTE If the heater is converted to accept 120V, the "Hat" wire of the 120V power supply has to be connected to the black wire (ACH1) on the power distribution board and the "Neutral" wire of the 120V power supply has to be connected to the red wire (ACN1) of the power distribution board. To wire the heater to 120V or 240V160 Hertz (Hz): 1. Remove the front door panel of the heater. 2. Connect the wires from the power source to the leads on the heater (Figure 21). NOTE No external junction box is required. Figure 21. Field Wiring Connections 6.3.1 Converting the Heater for a 120V Power Source A WARNING ELECTRICAL SHOCK HAZARD. To avoid an electrical shock hazard, which can result in serious injury or death, ensure that all electrical power to the system is turned off before approaching, inspecting, or troubleshooting any leaking plumbing that may have caused electrical devices in the surrounding area to get wet. The heater is configured at the factory to operate at 240 VAC, 60 Hz; to convert.the heater to 120 Volt, 60 Hz AC, reverse the voltage selector board on the power distribution board before the heater is connected to a power source: To convert the heater to 120V 60 Hertz (Hz): I. Identify the power distribution board on the heater to the right of the ignition control on the raceway (Figure 22). Page 24 Jandy' Pro Series, JXi" Gas -Fired Pool & Spa Healer I Installation & Operation Manual Figure 22. Power Distribution Board 2. Cut the plastic wire tie fastening the voltage selector board in place and discard it. Be careful not to abrade or damage any wiring or other components. Unplug the voltage selector board from the receptacle. See Figure 23. POWER TRIBUn BOARD WOREME VOLTAGE -SELECTOF BOARD Figure 23. Power Distribution Board With Voltage Selector Board Installed for 240 VAC 3. Rotate the voltage selector board 180' and reinsert it into the receptacle so that the hole in the board is not visible. Be sure that the board is securely seated in the receptacle. NOTE The voltage selector board Is keyed so that it will fit in only one (1) direction for either selected voltage (either side of the board). 6.4 Bonding CAUTION To prevent premature failure of the appliance resulting from stray voltages and voltage differentials, the heater must be bonded to other equipment which is part of the pool plumbing system with a solid copper wire not smaller in diameter than 8AWG (6 AWG in Canada). Zodiac Pool Systems, Inc., requires that the appliance be connected to a "bonding loop" that includes all electrical equipment in the system and on the equipment pad. Bonding lugs must be connected with a solid copper wire not smaller than 8 AWG (6 AWG in Canada). Failure to do so will void the Zodiac Pool Systems, Inc. warranty. Additionally, in the United States the National Electrical Code® (NECO) and in Canada the Canadian Electrical Code (CEC), require that all metallic components of a pool structure, including reinforcing steel, metal fittings and above ground components be bonded together (forming an "equipotential bonding grid") with a solid copper conductor not smaller than an 8 AWG (6 AWG in Canada). The NEC and CEC also require that the equipment and/ or appliances associated with the pool water circulating system, including, but not limited to, pump motors and heaters, be bonded together as part of the equipotential bonding grid. Zodiac Pool Systems, Inc. provides a special labeled bonding lug on the right side of the heater to accommodate this requirement. 6.5 Optional Remote Controls The JXi pool/spa heater controls can be wired for remote operation. All Zodiac® AquaLink" Control Systems will permit the heater to be operated by remote control. If you are setting up a new pool or spa system, call your local Jandy Pro Series distributor or Zodiac Pool Systems, Inc., 800.922.7933, for information on the correct Control System to meet your needs. ® WARNING RISK OF ELECTRIC SHOCK WHICH CAN RESULT IN SERIOUS INJURY OR DEATH. Before attempting installation or service, ensure that all power to the device is disconnected/turned off at the circuit breaker. Electrical wiring must be in accordance with the latest edition of the National Electric Code (NEC), ANSI®/ National Fire Protection Association (NFPA®) 70, unless local code requirements indicate otherwise. Refer to Figure 19 for electrical connections and wiring schematic. 6.5.1 . Connecting to a Remote Pool -Off -Spa Selector (3-Wire Connection) Install the Remote Pool -Off -Spa Selector: 1.

Operating Instructions 7.1 First -Time Start -Up Procedure ® WARNING Vent pipes and heater tops get hotl These surfaces can cause serious bums. Do not touch these surfaces while the heater is in operation. Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and replace any part of the control system and any gas control which has been underwater. Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the heater. Do not attempt repairs on the gas controls or* appliance. Tampering is dangerous and voids all warranties. I. Confirm that pool water is flowing normally through the pool system and equipment. 2. If it is a new pool or spa installation, operate the filter pump with the heater off long enough to completely clean the water. This will remove any installation residue from the water. 3. Clean the filter before starting the heater. 4. Start the heater in either Pool or Spa mode (see section 7.6, Operating the Heater). 5. Start the heater (see section 7.2, Lighting the Burner). 6. When the heater starts, confirm there is adequate water flow by touching the outlet header. The header should not be hot. Normally, water temperature will rise only a few degrees as it passes through the heater, and a "hot" header or pipe indicates low water flow. If ignition is unsuccessful: If ignition is unsuccessful, or the flame fails during normal operation, the ignition control shuts off the gas valve. The heater will then go through a post purge process and attempt to establish stable combustion two additional times. If ignition is unsuccessful after three attempts, the system shuts down and will automatically attempt to restart after one hour. To reset the heater to provide three (3) attempts to start: I. Turn OFF the control then turn it back ON. 2. Access either the Pool or Spa mode. 7.2 Starting the Heater Follow the instructions outlined below to start the heater.

Water Chemistry Proper Water Balance is the key to the enjoyment of your pool or spa experience and to the long life of your heater. The pH of your pool or spa's water is one of the factors that has the most impact on indicating how properly balanced the water is. The other factors are: temperature, total alkalinity, calcium hardness and total dissolved solids. Cold water is typically more acidic (corrosive), while hot water that is not properly balanced could lead to a scale forming (basic) condition. While the heater is in operation, if the PH is allowed to rise above 7.8 and the calcium hardness and total alkalinity are not properly maintained; calcium in the water could lose solubility, coating the copper tubes inside the heat exchanger. This will restrict the flow of water resulting in reduced efficiency and possible damage to the heater. If the pH is allowed to drop below 7.2, and the alkalinity is not properly maintained, the water will become more acidic. Acidic water has a tendency to dissolve metal components in the pool plumbing with the copper heat exchanger in the heater being a prime target. PH, Total Alkalinity (TA), temperature, Calcium Hardness and Total Dissolved Solids (TDS) play a role in whether the water is either corrosive or scale forming. These factors are combined in the Langelier Saturation Index, which is a method for determining whether or not water is properly balanced. See Table 7 below. Table 7. Water Saturation Index Saturation Index = pH + AF + CIF + TF -12.1 A-Factor-(AF), C-Factor-(CF), T-Factor-(TF) Total Alkalinity Calcium Hardness Temperature A -Factor `` 'C-Factor T Factor PPM Factor Value PPM Factor Value .F Factor Value 5 = 0.7 5 = 0.9 32 = 0.0 25 = 1 A 25 = 1.0 37 = 0.1 50 = 1.7 '• 50 = ' d3 46 = 0.2 75 = 1.9 75 = 1.5 53 = 0.3 100 = 2.0 10b 1.6 60 = 0.4 150 = 2.2 150 = 1.8 66 = 0.5 200• _. 2.3 200 1.9 76 = 0.6 300 = 2.5 300 = 2.1 84 = 0.7 400 = 2.6 4o0 = 2.2 94 = 08 800 = 2.9 1800 = 2.5 1105 = 0.9 1000 = 3.0 11000 = 2.6 1128 = 1.0 A saturation Index of 0 is perfectly balanced A negative saturation Index has corrosive tendencies A positive saturation index has scaling tendencies •saturation index of+0.3 or-0.3 should be used for visible, cosmetic pool surfaces. NOTE Acceptable "saturation Index° is between +0.5 and -0.5. When dealing with a cosmetic surface the index should be maintained between +0.3 and -0.3. A positive value Is more acceptable than a negative value. The practice of putting tablet -based sanitizers in the skimmer basket can produce heavily chlorinated water with very low pH in contact with metal parts of the heater that can cause serious damage. Practices like this should be discontinued and the use of floating sanitizer dispensers and check valves as backflow preventers with inline erosion -style feeders should be encouraged. If acidic conditions are present, there could be signs of metal in the pool water that could cause staining on the floor of your pool. This might manifest itself in the form of brown stains on the finish of your pool bottom or pool water discoloration. Your local pool dealer can test for metals in your water or can provide you with a test kit. Every effort should be made to maintain the water balance of your pool or spa in the proper range. Ignoring this very important component of your pool's water chemistry can make the water less enjoyable to bathe in and result in permanent damage to your heater and/or complete failure of individual components. Zodiac Pool Systems does not warrant heat exchangers damaged by corrosive water issues or from the build-up of calcium in the heater's heat exchanger. Any questions regarding proper water balance can be directed to our product support line at Zodiac or to your local pool dealer. NOTE: The Thermal Regulator Valve (TRV) is an indicator of how well the water chemistry is being maintained. The TRV Should be inspected before each pool season to ensure it is clean and operating properly. If you see signs of calcium buildup or corrosion the TRV should be replaced and your water balanced.
