Johnson Controls Unitary Products 1183509-UIM-L-0317 1183509-UIM-L-0317 INSPECTION As soon as a unit is received, it should be inspected for possible dat age during transit. If damage is evident, the extent of the damal should be noted on the carrier's delivery receipt. A separate request t inspection by the carrier's agent should be made in writing. See Loc Distributor for more information. Requirements For Installing/Servicing R-410A Equipment • Gauge sets, hoses, refrigerant containers, and recovery syste must be designed to handle the POE type oils, and the high pressures of R-410A. • Manifold sets should be high side and low side with low sic retard. • All hoses must have a 700 psig service pressure rating. • Leak detectors should be designed to detect HFC refrigerant. • Recovery equipment (including refrigerant recovery contain It must be specifically designed to handle R-410A. • Do not use an R-22 TXV. LIMITATIONS The unit should be installed in accordance with all National, State Local Safety Codes and the limitations listed below: 1. Limitations for the indoor unit, coil, and appropriate accessc must also be observed. 2. The outdoor unit must not be installed with any duct work in to stream. The outdoor fan is the propeller type and is not desii to operate against any additional external static pressure. 3. The maximum and minimum conditions for operation mu observed to ensure a system that will give maximum perforrt with minimum service. TABLE 1: Application Limitations air SECTION III: UNIT INSTALLATION LOCATION Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, air discharge, and service access. See Figures 1 & 2. For multiple unit installations, units must be spaced a minimum of 24" (61 cm) apart (coil face to coil face). If the unit is to be installed on a hot sun exposed roof or a paved ground area that is seasonally hot, the unit should be raised sufficiently above the roof or ground to avoid taking the accumulated layer of hot air into the outdoor unit. If the system is being installed during seasonally cold weather of 55°F or below, the preferred method is to weigh in the charge. For charging or checking the system charge at 55°F or below, refer to the "Optional Cold Weather Charging" procedures near the end of SECTION VI: SYSTEM CHARGE. There is an "Optional Cold Weather Charging" accessory kit to prevent the outdoor unit from taking in cold air below 55°F. The kit part number can be found in the list of accessory kits on the LIPGNET web site. be Provide adequate structural support for the unit.

The maximum allowable line length for this product is 80 1feet. To install more than the maximum allowable line length, co suit the Piping Application Guide (P/N 24077). I ADD -ON REPLACEMENT/RETROFIT When this unit is being used as a replacement for an R-410A unit, it is required that the outdoor unit, indoor coil, and metering device all be replaced. The following steps should be performed in order to insure proper system operation and performance. Line -set change out is also recommended. 1. Change -out of the indoor coil to an approved R-410A coil/ con- densing unit combination with the appropriate metering device. 2. Change -out of the line -set when replacing an R-22 unit with an R410-A unit is highly recommended to reduce cross -contamina- tion of oils and refrigerants. 3. If change -out of the line set is not practical, then the following pre- cautions should be taken. • Inspect the line set for kinks, sharp bends, or other restrictions, and for corrosion. • Determine if there are any low spots which might be serving as oil traps. • Flush the line set with a commercially available flush kit to remove as much of the existing oil and contaminants as possible. • Install a suction line filter -drier to trap any remaining contami- nants, and remove after 50 hours of operation. 4. If the outdoor unit is being replaced due to a compressor burnout, then installation of a 100% activated alumina suction -line filter drier in the suction -line is required, in addition to the factory installed liquid -line drier. Operate the system for 10 hours. Monitor the suction drier pressure drop. If the pressure drop exceeds 3 psig, replace both the suction -line and liquid -line driers. After a total of 10 hours run time where the suction -line pressure drop has not exceeded 3 psig, replace the liquid line drier, and remove the suction -line drier. Never leave a suction -line drier in the system longer than 50 hours of run time. 1183509-U IM-L-0317 A CAUTION: Special care must be taken to avoid recirculation of discharge air through condenser coil. 48" OVERHEAD CLEARANCE y NEC CLASS 1 WIRING WEATHERPROOF Q °o THERMOSTAT DISCONNECT SWITCH NEC CLASS 2 WIRING NOTE: Ensure a minimum of TO FURNACE OR 24" clearance between AIR HANDLER any two units.

FENC FIGURE 2: Alternative Installation Clearances a Johnson Controls Unitary Products 3 1183509-UIM-L-0317 GROUND INSTALLATION The unit should be installed on a solid base that is 2" (5.1 cm) above grade and will not shift or settle, causing strain on the refrigerant lines and possible leaks. Maintain the clearances shown in Figures 1 & 2 and install the unit in a level position. The base pad should not come in con- tact with the foundation or side of the structure because sound may f�e transmitted to the residence. The length of the refrigerant tubing between the outdoor unit and indoor coil should be as short as possible to avoid capacity and efficienlcy losses. Excessive spacing of the outdoor unit from the home can result in the refrigerant lines being restricted by trampling or being punctu�ed by lawn mowers. Locate the outdoor unit away from bedroom windows or other rooms where sound might be objectionable. Adverse effects of snow or sleet accumulating on the outdoor coil an be eliminated by placing the outdoor unit where -the prevailing wind does not blow across the unit. Trees, shrubs, corners of buildings, and fences standing off from the coil can reduce capacity loss due to i ind chill effect. Provide ample clearance from shrubs to allow adequate air to Lass across the outdoor coil without leaves or branches being pulled into the coil. ROOF INSTALLATION When installing units on a roof, the structure must be capable of sup- porting the total weight of the unit, including a pad, lintels, rails or any components used to minimize the transmission of sound or vibIration into the conditioned space. WALL MOUNT INSTALLATION Care must be taken to mount the outdoor unit on a solid base Ithat is sloped to shed water, secure from settlement, and is isolated frm the structural foundation or walls to prevent sound and vibration transmis- sion into the living space. On occasion, site conditions may require direct wall mounted brackets to be used to locate and support the outdoor unit. In these applications, care must be taken to address unit base pan support, structural integ- rity, safe access and serviceability, as well as the possible sond and vibration transmission into the structure. These applications are best served by a properly engineered solution. LIQUID LINE FILTER -DRIER The air conditioning unit's filter/dryer is located inside the unit on the liq- uid line between the outdoor coil and the liquid valve inside thg unit. _ A� Failure to do so or using a substitute drier or a granular type may result in damage to the equipment. Filter -Drier Source 1 Part No. I Apply with Models S1-401021 All PIPING CONNECTIONS The outdoor condensing unit must be connected to the indoor evapora- tor coil using field supplied refrigerant grade (ACR) copper t✓Jbing that is internally clean and dry. Units should be installed only wit the tubing sizes for approved system combinations as specified in i abular data sheet. The charge given is applicable for total tubing lengths up to 15 feet (4.6 m). See Piping Application Guide (P/N 24077)Ifor installing tubing of longer lengths and elevation differences. using a larger tnan spectnec tine size coutc result to oil return prop- lems. Using too small a line will result in loss of capacity and other problems caused by insufficient refrigerant flow. Slope horizontal vapor lines at least 1" (2.5 cm) every 20 feet (6.1 m) toward the out- door unit to facilitate proper oil return. If more than the 80 foot line length is necessary, facilitate proper refrigerant velocity with adjusted line diameter in accordance with the Piping Application Guide (P/N 24077). . .su This system uses R-410A refrigerant which operates at higher pres- sures than R-22. No other refrigerant may be used in this system. Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle R-410A. If you are unsure, consult the equip- ment manufacturer Never install a suction -line filter drier in the liquid line of an R-410A system. Failure to follow this warning can cause a fire, injury or death. PRECAUTIONS DURING LINE INSTALLATION 1. Install the lines with as few bends as possible. Care must be taken not to damage the couplings or kink the tubing. Use clean hard drawn copper tubing where no appreciable amount of bending around obstruction is necessary. If soft copper must be used, care must be taken to avoid sharp bends which may cause a restriction. 2. The lines should be installed so that they will not obstruct service access to the coil, air handling system, or filter. 3. Care must also be taken to isolate the refrigerant lines to minimize noise transmission from the equipment to the structure. 4. The vapor line must be insulated with a minimum of 1/2" foam rub- ber insulation (Armaflex or equivalent). Liquid lines that will be exposed to direct sunlight, high temperatures, or excessive humid- ity must also be insulated. 5. Tape and suspend the refrigerant lines as shown. DO NOT allow tube metal -to -metal contact. See Figure 3. 6. Use PVC piping as a conduit for all underground installations as shown in Figure 4. Buried lines should be kept as short as possible to minimize the build up of liquid refrigerant in the vapor line during long periods of shutdown. Fit;uKt 3: instaiiation or vapor Line 7. Pack fiberglass insulation and a sealing material such as perma- gum around refrigerant lines where they penetrate a wall to reduce vibration and to retain some flexibility. 8. For systems with total line length exceeding 75 feet (22.86 m), see Piping Application Guide (P/N 24077) for vapor and liquid line siz- ing, calibration of liquid line pressure loss or gain, determination of vapor line velocity, elevation limitations, TXV connections, system charging or traps. I 1183509-UIM-L-0317 TO INDOOR COIL TO OUTDOOR UNIT LIQUID LINE INSULATED *----VAPOR LINE CAP PVC CONDUIT FIGURE 4: Underground Installation PRECAUTIONS DURING BRAZING OF LINES All outdoor unit and evaporator coil connections are copper -to -copper and should be brazed with a phosphorous -copper alloy material such as Silfos-5 or equivalent. DO NOT use soft solder. The outdoor units have reusable service valves on both the liquid and vapor connections. The total system refrigerant charge is retained within the outdoor unit during shipping and installation. The reusable service valves are pro- vided to evacuate and charge per this instruction. Serious service problems can be avoided by taking adequate precau- tions to assure an internally clean and dry system. being brazed, because the temperature required is high enough to cause oxidation of the copper unless an inert atmosphere is provided. The flow of dry nitrogen should continue until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure dry nitrogen is introduced into the tubing. Only a small flow is necessary to displace air and prevent oxidation. PRECAUTIONS DURING BRAZING SERVICE VALVE Precautions should be taken to prevent heat damage to service valve by wrapping a wet rag around it as shown in Figure 5. Also, protect all painted surfaces, insulation, and plastic base during brazing. After braz- ing, cool joint with wet rag. i ms is nor a nacKseaung vanre. me service access port nas a varoe core. Opening or closing valve does not close service access port. If the valve stem is backed out past the chamfered retaining wall, the O-ring can be damaged causing leakage or system pressure could force the valve stem out of the valve body possibly causing personal injury. Valve can be opened by removing the service valve cap and fully insert- ing a hex wrench into the stem and backing out counter -clockwise until valve stem just touches the chamfered retaining wall. Connect the refrigerant lines using the following procedure: 1. Remove the cap and Schrader core from both the liquid and vapor service valve service ports at the outdoor unit. Connect low pres- sure nitrogen to the liquid line service port. 2. Braze the liquid line to the liquid valve at the outdoor unit. Be sure to wrap the valve body with a wet rag. Allow the nitrogen to con- tinue flowing. 3. Carefully remove the plugs from the indoor coil liquid and vapor connections at the indoor coil. j WET RAGS (Wrap wet rags around service valve or refrigerant lines prior to brazing). M23"o1 FIGURE 5: Heat Protection Do not install any coil in a furnace which is to be operated during the heating season without attaching the refrigerant lines to the coil. The coil is under pressure which must be. released to prevent excessive pressure build-up and possible coil damage. 4. Braze the liquid line to the indoor coil liquid connection. Nitrogen should be flowing through the indoor coil. 5. Slide the grommet away from the vapor connection at the indoor coil. Braze the vapor line to the evaporator vapor connection. After the connection has cooled, slide the grommet back into original position. 6. Protect the vapor valve with a wet rag and braze the vapor line connection to the outdoor unit. The nitrogen flow should be exiting the system from the vapor service port connection. After this con- nection has cooled, remove the nitrogen source from the liquid fit- ting service port. 7. Replace the Schrader core in the liquid and vapor valves. 8. Go to SECTION IV for TXV installation. 9. Leak test all refrigerant piping connections including the service port flare caps to be sure they are leak tight. DO NOT OVER - TIGHTEN (between 40 and 60 inch - lbs. maximum). Line set and indoor coil can be pressurized to 250 psig with dry nitro- gen and leak tested with a bubble type leak detector. Then release the nitrogen charge. Do not use the system refrigerant in the outdoor unit to purge or leak test. 10. Evacuate the vapor line, indoor coil, and liquid line to 500 microns or less. 11. Replace cap on service ports. Do not remove the flare caps from the service ports except when necessary for servicing the system. Do not connect manifold gauges unless trouble is suspected. Approx- imately 314 ounce of refrigerant will be lost each time a standard man- ifold gauge is connected. Johnson Controls Unitary Products 5 1183509-UIM-L-0317 12. Release the refrigerant charge into the system. Open both the liq- uid and vapor valves by removing the plunger cap and with an allen wrench back out counter -clockwise until valve stem just touches the chamfered retaining wall. If the service valve is a ball valve, use a Crescent wrench to turn valve stem one -quarter turn counterclockwise to open. Do not overturn or the valve stem may break or become damaged. See "PRECAUTIONS DURING BRAZING SERVICE VALVE". 13. Replace plunger cap finger tight, then tighten an additional 1r12 turn (1/2 hex flat). Cap must be replaced to prevent leaks. ivever attempt to repair any orazea connections wnue me system Is under pressure. Personal injury could result. See "System Charge" section for checking and recording system charge. SECTION IV: COIL METERING DEVICES A piston or a TXV is to be installed in the field. There is an instal ation manual that comes with the TXV kit. It is recommended to install the piston or TXV kit prior to installation of coil and brazing of line sett Until brazing is completed and cooled, the TXV sensing bulb must not be installed. The outdoor technical guide for outdoor units should be consul ed for required piston or TXV on the indoor coil. The piston and the Sc rader core are supplied with the outdoor unit. When the piston is used i�stead of the TXV, the Schrader core is installed in the suction line equalizer connection port and is capped with the supplied plastic cap. The Schrader core must not be installed if the TXV is installed, bec i se the TXV equalizer line attaches to the equalizer connection port. A COIL UNDER PRESSURE. Verify that pressure has been released by depressing Schrader valve core. The coil requires a metering device to be added. See outdoor unit documentation for correct TXV or piston to t1, used. To prevent moisture and contaminates from entering the system, the coil should not be open to atmosphere for extended periodsof time. If the coil cannot be brazed into the refrigeration system dunpg a rou- tine installation period, the ends should be temporarily closed or plugged. For a short term delay, use masking tape over the ends of the copper tubing to close the tube from the air. For a lo�tger term delay, use plugs or caps. There is no need to purge the coil if this pro- cedure is followed.

If a leak is suspected, leak test with dry nitrogen to locate the leak. I�Repair the leak and test again. To verify that the system has no leaks, simply close the valve to the vacuum pump suction to isolate the pump and hold the syste1in under vacuum. Watch the micron gauge for a few minutes. If themicron gauge indicates a steady and continuous rise, it's an indicatof a leak. If the gauge shows a rise, then levels off after a few minutes and remains fairly constant, it's an indication that the system is leak ree but still contains moisture and may require further evacuation if the reading is above 500 microns. SECTION VI: SYSTEM CHARGE To ensure that your unit performs at the published levels, it is important that the indoor airflow is determined and refrigerant charge added accordingly. MEASURE INDOOR AIR FLOW To determine rated air flow for a specific match, consult the teThnical lit- erature at www.upgnet.com. When attempting to match this air flow, select the lowest possible speed tap, measure the actual flow, and adjust as necessary. To measure actual air flow, it is not an acceptable method to just check the jumper pin setting tables and is to assume 0.5" water column total external static pressure. To determine indoor air flow, first measure the static pres ure with a manometer between the filter and blower. On a single -piece air handler, take a second reading after the coil. On a furnace or modular air han- dler, take the second reading after the heat exchanger butt before the indoor coil. Add the negative return static to the positive supply static to determine the system total static pressure. Treat the negative return static as a positive pressure (even though it is a negative reading). If there is static pressure on the blower (i.e. -.10) return, add i to a supply static (.40) which equals a (.50) total system static pressu ,e. Compare this value to the table for the indoor unit's static pressure v$. CFM or to a curve chart. SYSTEM CHARGING For cold weather charging of the system at temperatures of 55°F or below, refer to the "Optional Cold Weather Charging" procedures near the end of SECTION V1. SYSTEM CHARGE. R-410A refrigerant cylinders are rose colored. Always charge the system slowly with liquid R-410 refrigerant. The factory charge in the outdoor unit includes enough charge for the unit, a 15 ft. (4.6 m) line set, and the smallest indoor coil match -up. Some indoor coil matches may require additional charge. See tabular data sheet provided in unit literature packet for charge requirements. fi t- Do not leave the system open to the atmosphere. The "TOTAL SYSTEM CHARGE" must be permanently stamped on the unit data plate. TOTAL SYSTEM CHARGE is determined as follows: 1. Determine the Base Charge shipped in the outdoor unit from the Tabular Data Sheet included with the outdoor unit. 2. Determine the charge adder for the matched indoor unit from the Tabular Data Sheet included with the outdoor unit. 3. If the lineset length is greater than 15 feet (4.6 m), calculate the charge adder for actual lineset length using the Tabular Data Sheet included with the outdoor unit. 4. Once the charge adders for matched indoor unit and for lineset have been weighed in, verify the system operation against the temperatures and pressures in the Charging Chart for the outdoor unit. Locate Charging Charts on the outdoor unit and also in the Service Application Data on www.upgnet.com. Follow the Subcool or the Superheat charging procedure in the section below accord- ing to the type of indoor metering device in the system, and 'allow ten minutes after each charge adjustment for the system operation to stabilize. Record the charge adjustment made to match the Charging Chart. 5. Verify that TOTAL SYSTEM CHARGE = Base Charge (as shipped) + charge adder for matched indoor unit + charge adder for actual lineset length + charge adjustments to match Charging Chart. 6. Permanently stamp the unit data plate with the TOTAL SYSTEM CHARGE as defined above. This method is to be used whenever additional refrigerant is required for the system charge. k a� o"" j 77 DO NOT attempt to pump Total System Charge" into outdoor unit for maintenance or service. This may cause damage to the compressor and/or other components. Recover and weigh "System Charge" into an appropriate recovery cylinder for any instances requiring evacua- tion. psi--•r>Te °"h .S J O7 TT . It is recommended to not attempt to pump more than the 'Factory Charge" and an additional 15 foot line charge into a tube and fin out- door unit for maintenance or service. This can cause damage to the compressor and/or other components. AL Refrigerant charging should only be carried out by a qualed air con- ditioning contractor. nson 1183509-U I M-L-0317 A Condenser subcooling is obtained by calculating the difference of the saturated refrigerant temperature of the pressure measured at the liquid base valve and the liquid tube temperature as measured at the liquid Compressor damage will occur if system is improperly charged. On base valve. new system installations, charge system per tabular data sheet for the matched coil and follow guidelines in this instruction. Subcooling Temp. (TC) = Saturated Temp.

Please follow the instructions on the unit. If those instructions are not readily available, follow the instructions below. 1. Set the system running in cooling mode by setting the thermostat at least 6°F below the room temperature and operate system for at least 10 —15 minutes. 2. Refer to the technical guide for the recommended indoor airflow and verify it is correct (it should be 350- 400 SCFM per ton). 3. Measure and record the indoor wet bulb (WB) and the outdoor ambient dry bulb (DB) temperature. 4. Using the charging chart located on the unit, find the intersection of the indoor wet bulb and the outdoor dry bulb. This is the recom- mended liquid pressure (and subcooling value). 5. Measure and record the pressure at the liquid valve pressure port and compare to the value obtained in step 4. 6. Add charge if the measured liquid pressure is lower than the rec- ommended value. Remove I recover charge if the measured liquid pressure is above the recommended value. Example: The liquid pressure listed at the intersection of the indoor WB and the outdoor DB 320 psig. Pressure at the liquid valve is 305 psig. It would be necessary to add refrigerant to increase the liquid pressure to 320 psig. TABLE 2: R-410A Saturation Properties SUPERHEAT CHARGING METHOD - PISTON INDOOR 1. Set the system running in cooling mode by setting the thermostat at least 6°F below the room temperature and operate system for at least 10 —15 minutes. 2. Refer to the technical guide for the recommended airflow and ver- ify indoor airflow (it should be about 350-450 SCFM per ton). 3. Measure and record the outdoor ambient (DB) temperature and the suction pressure at the suction service valve. 4. Using the charging chart located on the unit, find the intersection of the outdoor ambient dry bulb and the suction pressure obtained in step 3. This is the recommended suction tube temperature at the service valve. 5. Measure and record the suction tube temperature at the service valve and compare to the recommended temperature obtained in step 4. 6. Add charge if the measured suction temperature in step 5 is above the recommended value. Remove I recover refrigerant if the mea- sured suction temperature is below the recommended value. Example: The suction tube temperature listed on the table at the intersection of the outdoor DB and the suction pressure is 63°F. Temperature of the suction tube at the service valve is 68°F. It would be necessary to add refrigerant to drop the suction tube temperature to 63°F.

Review Owners Guide and provide a copy to the owner and guidance on proper operation and maintenance. Instruct the owner or the opera- tor how to start, stop and adjust temperature setting. When applicable, instruct the owner that the compressor is equipped with a crankcase heater to prevent the migration of refrigerant to the compressor during the OFF cycle. The heater is energized only when the unit is not running. If the main switch is disconnected for long peri- ods of shut down, do not attempt to start the unit until 8 hours after the switch has been connected. This will allow sufficient time for all liquid refrigerant to be driven out of the compressor. The installer should also instruct the owner on proper operation and maintenance of all other system components. MAINTENANCE 1. Dirt should not be allowed to accumulate on the outdoor coils or other parts in the air circuit. Clean as often as necessary to keep the unit clean. Use a brush, vacuum cleaner attachment, or other suitable means. 2. The outdoor fan motor is permanently lubricated and does not require periodic oiling. 3. If the coil needs to be cleaned, use clean water to wash dust, dirt, and debris from outdoor condensing coil. DO NOT use coil cleaners to clean outdoor condensing coil. Cleaners containing HF —, hydroxides, chlorides, and sulfates can greatly reduce the lifetime of the micro channel coil. 4. Refer to the furnace or air handler instructions for filter and blower motor maintenance. 5. The indoor coil and drain pan should be inspected and cleaned regularly to prevent odors and assure proper drainage.
