Close the Low Pressure side of the manifold gauge, and turn off the vacuum pump. 7. Wait for 5 minutes, then check that there has been no change in system pressure. 8. If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap 9. from the packed valve (high pressure valve). Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a 1 /4 counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds. 10. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure. 11. Remove the charge hose from the service port. valve body valve stem ,Cap 12. Using hexagonal wrench, fully open both the high pressure and low pressure valves. 13. Tighten valve caps on all three valves (service port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed. OPEN VALVE STEMS GENTLY When opening valve stems, turn the hexagonal wrench until it hits against the stopper. Do not try to force the valve to open further. Note on Adding Refrigerant Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. For example, in North America, the standard pipe length is 7.5m (25'). In other areas, the standard pipe length is 5m (16'). The refrigerant should be charged from the service port on the outdoor unit's low pressure valve. The additional refrigerant to be charged can be calculated using the following formula: Liquid Side Diameter 4)6.35(1 /4") (�9.52(3/81 12.7(1 /2") (Total pipe length - (Total pipe length - (Total pipe length - R22 (orifice tube in the indoor unit}: standard pipe length)x standard pipe length)x standard pipe length)x 30g (0.32oZ)/m(ft) 65g(0.69oZ)/m(ft) 115g(1.23oZ)/m(ft) (Total pipe length - (Total pipe length - (Total pipe length - R22 (orifice tube in the outdoor unit): standard pipe length) standard pipe length) standard pipe length) x15g(0.16oZ)/m(ft) x30(O.32oZ)/m(ft) x60g(0.64oZ)/m(ft) R41 OA: (Total pipe length - (Total pipe length - (Total pipe length - (orifice tube in the indoor unit): standard pipe length) standard pipe length) standard pipe length) x30g(032oZ)/m(ft) x65g(0.69oZ)/m(ft) x115g(1.23oZ)/m(ft) R410A: (Total pipe length - (Total pipe length - (Total pipe length - (orifice tube in the outdoor unit): standard pipe length) standard pipe length) standard pipe length) x15g(0.16oZ)/m(ft) x30g(O.32oZ)/m(ft) x65g(0.69oZ)/m(ft) (Total pipe length - (Total pipe length - (Total pipe length - R32 : standard pipe length)x standard pipe length)x standard pipe length)x 12g(0.13oZ)/m(ft) 24g(0.26oZ)/m(ft) 40g(0.42oZ)/m(f0 /!\CAUTION DO NOT mix refrigerant types. Only for Australia models: • This unit contains factory charged refrigerant covering 20m of refrigerant piping and additional refrigerant charge on the installation site is not required for an installation with up to 20m refrigerant piping. When refrigerant piping exceeds 20m, additionally charge an amount calculated from the pipe length and the above table for the portion in excess of 20m. • If an existing pipe system is used, a required refrigerant charge volume will vary depending on the liquid pipe size. Formula to calculate the volume of additional refrigerant required: Additional charge volume (kg) _ { Main length (m) — Factory charged volume 20(m) } x 0.03(kg/m) • Make sure to remove the additional refrigerant amount according to the nameplate rated charge (under 5m refrigerant piping ) under market or government verification testing .

I INSTALLATION CLEARANCES I Left Side ............. 0 Inches Right Side......... 0 Inches Back .................. 0 Inches I Front ............... tSee Notes �--------- - - - -- Table 1. Minimum Unit Clearances 4 • Use transition fittings if the supply and/or return airopenings of the unit do not match the duct openings. These transitions should be dimensioned in accordance with standard practice as specified in the ASHRAE recommendations for duct transitions. • Flexible connectors may be used between the unit and the ductwork to prevent transmission of vibration from the unit to the structure. If electric heater kits are installed, heat resistant material must be used for the flexible connector at the supply air end of the unit. • It is good practice to seal all connections and joints with industrial grade sealing tape or liquid sealant. Requirements for sealing ducts vary from region to region. Consult with local codes for requirements specific to your area. Unconditioned Spaces All duct work passing through unconditioned space must be properly insulated to minimize duct losses and prevent condensation. Use insulation with an outer vapor barrier. Refer to local codes for insulation material requirements. Air Filters B6 Series Air Handlers are not supplied with an air filter when shipped from the factory. The installer must provide a high velocity filter that is appropriately sized to the return air duct opening or filter rack located in the bottom of the unit. Accessing the filter does not require tools and can be removed from the front of the unit by removing the filter door. See Unit Maintenance (page 14) for filter sizes and installation information. OWARNING: Never operate the air handler without a filter or with doors removed. Dust and lint can build up on internal components, resulting in loss of efficiency, equipment damage, and possible fire. Acoustical Duct Work • Certain installations may requirethe use of acoustical lining inside the supply duct work. Acoustical insulation must be in accordance with the current revision of the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) application standard forduct liners. Duct lining must be UL classified batts or blankets with a fire hazard classification of FHC-25/50 or less. • Fiber duct work may be used in place of internal duct liners if the fiber duct work is in accordance with the current revision of the SMACNA construction standard on fibrous glass ducts. Fibrous duct work and internal acoustical lining must be NFPA Class 1 air ducts when tested per UL Standard 181 for Class 1 ducts. * Damping ducts, flexible vibration isolators, or pleated media -style filters on the return air inlet of the air handler may be used to reduce the transmission of equipment noise eminating from the air handler. These treatments can produce a quieter installation, particularly in the heated space. However, they can increase the pressure drop in the duct system. Care must be taken to maintain the proper maximum pressure rise across the air handler, temperature rise and flow rate. This may mean increasing the duct size and/or reducing the blower speed. These treatments must be constructed and installed in accordance with NFPA and SMACNA construction standards. Consult with local codes for special requirements. For best sound performance, be sure to install all the needed gaskets and grommets around penetrations into the air handler, such as for electrical wiring.

In this case follow instructions 1-4 as listed above but also remove the blower access door and blower assembly. The blower assembly is secured with two screws on either side near the front. With these removed the blower assembly can slide out of the front of the unit. Install the coil and drain pan as described in step 5 and then replace the blower assembly. Make sure the flanges on the sides of the blower assembly are captured by the pockets in the blower deck. It may be necessary to lift the blower assembly during insertion to allow the lower blower leg to clear the side of the drain pan. The blower will stop against the back of the blower deck. Replace the two screws and the blower access door and procede with steps 6-9. 6. Remove the plug from one of the threaded holes in the horizontal drain pan. Completely remove the webbing located in the threaded holes of the drain pan. IMPORTANT: If the webbing is not removed, the condensatewill not drain properly and ceiling damage may occur. NOTE: It is recommended that the suction line be insulated up to the coil inside of the cabinet. 7. Insert the plug (from horizontal drain pan) into the open and unused drain hole in the drain pan at the bottom of the unit to block bypass air. 8. Remove the corresponding drain line knockout from the coil access door to allow access to the horizontal drain. 9. Replace the door and attach the drain line. Circuit Breaker Cover Installation The air handler circuit breaker cover is designed to protect the breakers of an installed heater kit from debris and condensation.The cover attaches to the breaker recess of the air handler upper access door using a double -sided adhesive gasket. See Figure 5. The heater kit circuit breaker toggles are still accessible and can be switched with the cover in place. There are 2 different circuit breaker cover sizes: • 2-breaker cover for 2, 2.5, 3, 3.5, & 4 ton air handlers. • 3-breaker cover for 5 ton air handlers. Afterthe heater kit is properly installed, remove the appropriate knockouts in the upper air handler access door and follow these instructions to install the breaker cover: 1. Clean any oil, dirt, or insulation fibers from the recess area of the air handler access door. This step is important for ensuring the gasket adheres properly to the sheet metal door. 2. Remove release paper from one side of the gasket and attach to back side of the breaker cover. NOTE: For proper alignment, It is recommended to leave the center section of the gasket in place when attaching the gasket to the breaker cover. Remove the center section after the gasket is applied to the breaker cover. 3. Removethe release paperfrom theothersideofthegasket and attach to the circuit breaker recess area. 4. Press firmly along all four sides of the cover to ensure gasket and cover are securely attached to the access door. Refrigerant Line Connections I zhWARNING: I NITROGEN HEALTH El I FLAMMABILITY REACTIVITY O O MinimN Hnzard 151Ighl Hezam The coil in the air handler is factory shipped with a nitrogen charge. Avoid direct face exposure or contact with valve when gas is escaping. Always ensure adequate ventilation is present during the depressurization process. Address any uncertainties before proceeding. Failure to comply with this warning could result in equipment damage, personal injury, or death. The installer should make every effort to ensure the field installed refrigerant containing components of the system have been installed in accordance with these instructions and sound installation practices for reliable system operation and longevity. a CIr�4it Breakers Recess CirCUit B reaker Cover Air Handler A«ess paQr Figure 5. Circuit Breaker Cover • The air handler coil does not contain a refrigerant charge. Refer to the installation instructions supplied with the outdoor unit for refrigerant charge information. • The refrigerant piping to each air handier (or coil) should be of equal length and size. Run the copper pipes from condensing unit to a point equidistant between the air handlers (or coils). Place atee in the lines at this point. After the tee (as close to the air handler as practical), reduce the pipe size to match the piping of the air handler or coil. • Always refer to the installation instructions supplied with the outdoor unit for piping requirements. The suction and liquid lines mustbe sized in accordance with the condensing unit specifications. See Figure 11 (page 15) for liquid and suction line locations. • When connecting refrigerant linesets together, it is recommended that dry nitrogen be flowing through the joints during brazing. This will prevent internal oxidation and scaling from occurring. • Refrigerant tubing should be routed in a manner that minimizes the length of tubing and the number of bends in thetubing. Itshould be supported in amannerthat prevents itfrom vibrating or abrading during system operation. Tubing should be kept clean of foreign debris during installation. • If precise forming of refrigerant lines is required, a copper tubing bender is recommended. Avoid sharp bends and contact of the refrigerant lines with metal surfaces. • Refrigerant lines should be wrapped with pressure sensitive neoprene orothersuitable material wherethey pass against sharp sheet metal edges. • B6 Series air handlers are charged (with nitrogen) through service valves on the end of the liquid tube for each circuit. These must be removed before brazing the line sets. Orifice Removal & Installation The orifice installed in the air handler has been sized for use with the most popularly matched outdoor units. The orifice size as shipped from the factory is listed on the air handler rating plate. Perform steps 1 - 9 (page 8) to confirm that the orifice size meets the requirements outlined in the outdoor unit installation manual. 1. Remove the cap from the end of the liquid line. 2. Verify pressurization by depressing the Schrader valve on the end of the liquid line. Listen for any escaping gas. If there is no pressure, test the coil for leakage. • If leakage is found, clearly mark the location of the leak and return the coil to the distributor for processing. • If no leaks are found, the coil may be installed. 3. Depress the valve to relieve all pressure from the coil. 4. Remove and discard the valve core. 0 CAUTION: To prevent damage to the unit or internal components, it is recommended that two wrenche's be used when loosening or tightening nuts. Do not over tighten! 5. Using two wrenches, loosen the nut and distributor body as shown in Figure 6.Turn the assembly nutcounter-clock- wise until the orifice body halves are seperated. 6. Inserta light -gauge wire hook between the distributor body and the restrictor orifice while being careful not to scratch either part. Carefully remove the restrictor orifice from the distributor body. See Figure 7. 7. Check the actual size of the new orifice. NOTE: The size is stamped on its side. Do not use pin gauges to measure the orifice diameter. 8. Insert the new orifice into the distributor body, rounded end down. See Figure 8. CAUTION: To prevent damage to the unit or internal components, it is recommended that two wrenches be used when loosening or tightening nuts. Do not over tighten! 9. Realign the assembly nut on the distributor body and hand tighten both components. Mark a line on both bodies and then tighten an additional 1 /4 turn using two wrenches. The movement of the two lines will show how much the nut is tightened. If a torque wrench is used, tighten to 14-12 ft. lbs. or 14-16 Nm. Connecting the Linesets The steps in the Orifice Removal & Installation section must be performed before the linesets are connected. IMPORTANT NOTES FOR HORIZONTAL OR DOWNFLOW INSTALLATIONS WITH TXV VALVE: • The sensing bulb must be located flush against the suction line for optimum heat transfer. • Avoid attaching the sensing bulb to the lowest part of the suction line where condensate may accumulate. • Do not locate the sensing bulb on vertical sections of the lineset. • For horizontal lines, the bulb should not be located at 12 or 6 o'clock position of the suction line. The best location is at 4 or 8 o'clock. • For additional information on proper sensing bulb locations, please refer to the valve manufacturer's instructions. Figure 6. Loosening of Nut & Distributor Body Figure 7. Restrictor Removal from Distributor Body Figure 8. Installation Of New Orifice 1. Remove grommets from line set holes. 0 CAUTION: It is recommended that a wet rag be wrapped around the suction line in front of the close off plate or the sensing bulb (if TXV is installed) before applying heat. Failureto keep components cool during brazing may result in structural damage, premature equipment faiIure, or possible personal injury. 2. Cutoff the heat shrink and remove the plug from the suction line. 3. Route and cut both lineset tubes to proper length in accordance with the outdoor unit specifications. Verify the ends are round, clean, and free of any burrs. 4. Position grommet on line set with sufficient distance away from brazing area. Brazing processes can permanently damage grommets. 5. Connect the suction and liquid lineset tubes. & CAUTION: It is recommended that a wet rag be wrapped around the suction line in front of the close off plate or the sensing bulb (if TXV is installed) before applying heat. Failureto Keep components cool during brazing may result in structural damage, premature equipment failure, or possible personal injury. 6. Braze the individual connections with dry nitrogen flowing through the joints. NOTE: This will prevent internal oxidation and scaling from occurring. 7. Wrap the refrigerant lines with pressure sensitive neoprene or other suitable material especially where the lines enter the opening in the sheet metal. 8. Evacuate the system of moisture and non-condensables to prevent low efficiency operation or damage to the unit. The suggested range of evacuation is 350 - 500 microns. 9. Charge the system with refrigerant. Refer to the outdoor unit installation manual for additional charging instructions. 10. Check the system for leaks, including the lineset and the brazed joints. 11. Replace all grommets and properly dispose of all removed parts. Condensate Drainage 0 CAUTION: The air handler must be level to ensure proper condensate drainage. An unlevel installation may result in structural damage, premature equipment failure, or possible personal injury. Methods for disposing of condensate vary according to local codes. Refer to local codes or authority having jurisidiction for restrictions and proper condensate disposal requirements. The drain pan that is supplied with this air handlercontains a primary and secondary drain fitting. The condensate is drained from the unit through two 3/4" female pipe fittings located on the front side of the unit as shown in Figure 9. The drain pan must be drained with field supplied tubing or pvc pipe and adequately trapped. Both drain tubes must have a minimum diameter of 3/4" and be trapped separately. IMPORTANT: Failure to install a trap may result in condensation overflowing the drain pan, resulting in substantial water damage to surrounding area. uPFLOW HORIZONTAL 3/4' Adapter w/ 3/4" dia. hose barb DOWNFLOW 3/4' minimum dia. PVC or flexible tubing NOTES: 1. The drain lines must maintain a downward slope to ensure proper condensate drainage. 2. Each condensate drain must be trapped separately using a J-Trap or field supplied loop. Figure 9. Condensate Drainage Example Route both lines to a suitable drain, avoiding sharp bends and pinching of the lines. The drain should maintain a minimum horizontal slope in the direction of discharge of not less than 1" vertical for every 10 ft of horizontal run. If the air handler is located in or above a living space where damage may resultfrom condensate overflow, an auxiliary drain pan shall be installed underthe unit. A separate drain line should extend from the pan to a conspicuous point and serve as an alarm indicating that the primary drain is restricted. As an alternative to a separate drain line, an approved water level indicator or float switch device may be used to shut down the unit in the event water is detected in the auxiliary pan. Install a single 5 inch trap in the condensate drain line as close to the coil as possible. Make sure that the top of the trap is below the bottom of the drain pan to prevent the condensate from overflowing the drain pan. NOTE: There must be only one trap in the drain line. Using more than one trap may prevent drainage. Prime the trap with water. Insulate the drain if it is located in an unconditioned space, and test the condensate line for leaks. Consult local codes for additional restrictions or precautions. During system checkout, inspect the drain line and connections to verify proper condensate drainage. ELECTRICAL CONNECTIONS I OWARNING: I ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD Failure to follow safety warnings exactly could result in serious injury or property damage. Improper servicing could result in dangerous operation, serious injury, death or property damage. Before servicing, disconnect all electrical power to furnace.

If replacing any of the original wires supplied with the unit, the replacement wire must be copper wire consisting of the same gauge and temperature rating. Provide power supply for the unit in accordance with the unitwiring diagram, and the unit rating plate. Use UL listed conduit and conduit connectors for connecting the supply wires to the unit and for proper grounding. Field supplied bushings for the power supply cables must be added to support and protect the power supply cables. All 208/230 Volt units are shipped from thefactory wired for 240 volt operation. For 208V operation, remove the lead from the transformer terminal marked 240V and connect it to the terminal marked 208V. Thermostat Connections • Thermostat connections shall be in accordance with the instructions supplied with the thermostat. The thermostat used with this equipment must operate in conjunction with any installed accessories. Typical AC and air handler hookups are shown in Figure 13 (page 24). 0 CAUTION: Isolation must be maintained from the external Class 2 output of any transformer in a cooling circuit. Use a thermostat with isolating contacts to prevent inter -connection of Class 2 outputs. • Where local codes require thatthe thermostat wiring must be routed through a conduit or raceway, splices can be made inside the unit; however, all wiring must be NEC Class 1 and separated from incoming power leads. • The thermostat should be mounted about 5 feet above the floor on an inside wall. DO NOT install the thermostat on an outside wall or any other location where its operation may be adversely affected by radiant heat from fireplaces, sunlight, or lighting fixtures, and convective heat from warm air registers or electrical appliances. Refer to the thermostat manufacturer's instruction sheet for detailed mounting and installation information. • Install the grommet, which is packed with the unit, in the hole for low -voltage wires. Properly connect the low -voltage wiring between the thermostat, outdoor unit, and control board. NOTE. When the low voltage wires are positioned in this grommet, the grommet will prevent chafing and/or shorting of the low voltage leads. Grounding A WARNING: The unit cabinet must have an uninterrupted or unbroken electrical ground to minimize personal injury if an electrical fault should occur. Do not use gas piping as an electrical ground! This unit must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code (ANSI/NFPA 70) orthe CSA C22.1 Electrical Code. Use the grounding lug provided in the control box for grounding the unit. Control Board The control board in the air handler controls the timing sequence of the elements. The board is equipped with a 3 second blower on delay and a 15 second blower off delay in heating and a 40 second blower off delay in cooling. 10 See Figure 15 (page 25) or Figure 16 (page 25) and Table 13, (page 22) for control board modes and actions. Twinning These instructions are to be used when connecting two B5 or B6 air handlers (2-5 ton models) to a common single stage A/C condensing unit or heat pump. Twinning is possible for B5 units with PSC or X-13 motors and B6 units with PSC or fixed speed (FSHE) motors. Twinning is not possible for units with variable (VSHE) speed motors. All low voltage wiring instructions, cautions, and warnings accompanying the air handler remain applicable, except for: Line & Low Voltage Connections a. The line voltage connections for both air handlers must be the same phase and on the same leg of power. b. When matched with an S3BM or an S313W series AC outdoor unit, both air handler's 24V transformers must be removed from the control circuit by removing and discarding the RED wire located on the transformer's secondary. These outdoor units come standard with 24V power supply sufficient for powering both air handlers. c. Low voltage wiring should be connected as shown in Figure 14 (page 24). d. Wire all other low voltage thermostat terminals to both air handlers as shown in Figure 13 (page 24). NOTE: If there is any other air moving device in the duct work, consult the factory for a resolution. Heater Kits When electric heat packages with circuit breakers are field - installed, the circuit breaker may be used as a disconnecting means in most applications. Reference the NEC and local codes for disconnect requirements. If a heater kit is installed: 13613M, B6EM, & B6VM air handlers are shipped from the factory without an electric heater kit installed. If electric heat is desired, a heater kit may be purchased separately and field installed. Determine the correct size heater kit for your unit by referring to the list below or the units rating label. A -Size Cabinet ............................................... 15Kw max B-Size Cabinet ............................................... 20Kw max C-Size Cabinet .............................................. 30Kw max 1. Connect the 2 wire plug of the air handler to the mating 2 wire plug of the heater kit. 2. Connect the line voltage leads to the circuit breaker or terminal block provided. 3. Connect the heater kit plug with the mating receptacle on the air handler control board. If a heater kit is not installed:, 1. Remove the 2 wire plug of the air handler by cutting the wires and discarding the plug. 2. Strip the ends of the 2 air handler wires and connect to the line -voltage leads with the 2 wire nuts provided. Humidifier The unit has an output to power a humidifier when the blower is running. This output is rated to 1.0 amp at 2081240V. Dehumidification Options The motor control board has a DHUM or D connection that allows the system to increase the amount of humidity that is removed from the circulating air. See Figure 17 & Figure 18 (page 26) This is accomplished by reducing the CFM and allowing the cooling coil to become colder. This will only MOTOR HUMIDISTAT CONTROL BOARD DHUM ..............-^-- RHUM Figure 10. DHUM Wiring Configuration occur when there is a call for cooling. There are many ways that this can be electrically wired. 1. If the room thermostat incorporates a humidity sensor and DHUM output, connect the DHUM on the thermostat to the D terminal on the motor control board. See Figure 10. 2. If using a separate humidistat, connect the DHUM & R terminals on the humidistat to the D & R terminals on the motor control board of the air handler. In this option, the DHUM output of the humidistat must be set so it is only closed when there is a call for dehumidification. 3. If a humidistat is notavailable, it is an acceptable option toconnectthe R & Dterminalson the motorcontrol board together with a field supplied wire. This option causes the blower to run at a reduced CFM for 10 minutes after a call for cooling. NOTE: If outdoor unit is a heat pump, connect the 0 terminal to the D terminal. Electronic Air Cleaner (EAC) The unit has an output to power an electronic air cleaner when the blower is running. This output is rated to 1.0 amp at 2081240V. See Figure 16 (page 25) and Figure 17 (page 26). STARTUP & ADJUSTMENTS Before You Start the Unit Prior to start-up, complete the following inspections: 4 Verify the unit is level and properly located with adequate clearances for servicing the unit as shown in Table 1, (page 4 Check ondensate drain line(s) for proper drainage. Verify the surrounding area and top of the unit is free from obstructions and debris. Check all duct connections. Make sure the duct work is adequately sealed to prevent air leakage. Check all coil connections for leaks. Verify that the line voltage power leads are securely connected and the unit is properly grounded. Make sure all doors are installed before restoring power to the unit Verify the thermostat is wired correctly. Make sure all low voltage wires are securely connected. Verify the powersupply branch circuit overcurrent protection is sized properly. Verify filter is properly and securely installed. IMPORTANT: Before starting the unit, install the initial charge on units that are factory shipped with a nitrogen holding charge: 1. Read all installation instructions first. 2. Purge the nitrogen holding charge. 3. Evacuate the unit to 350 - 500 microns. 4. Allow the unit to remain under vacuum for at least 30 minutes. 5. Weigh in the proper amount of new (or reclaimed) refrigerant. Refer to the air conditioner or heat pump installation manual for the proper type and quantity of refrigerant. 11 Air Circulation Running the Blower Continuously Set the thermostat's system mode to OFF and the thermostat's fan mode to ON. The blower motor should run continuously. Check for air delivery at the register(s). Ensure that there are no obstructions at the registers or in the ducts. Selecting Continuous Low Speed Fan Operation (Standard Blower) The air handler is equipped with an option of continuous low speed fan operation. When G is energized without YN2, the air handler will operate using the cooling speed. With G & YN2 or YN2 energized, the air handler will operate in the selected cooling speed (including 40 sec blower -off delay). Turning the Blower Off Set thermostat's fan mode to AUTO, the blower will shut down immediately. System Cooling 1. Set the thermostat's system mode to COOL. and fan mode to AUTO. Lower the thermostat's temperature made below room temperature and observe that the blower energizes. Check the air being discharged at the register is cooler than room temperature. Verify unit refrigerant pressures are in order. Blowershould be turning in direction indicated by arrow. Blower Configurations Determining Nominal System Capacity To select the appropriate airflows for the air handler, the nominal system capacity must be known. The nominal system capacity is always the nominal capacity of the outdoor unit. However, in some situations the nominal system capacity may not be the same as the nominal capacity of the air handler. Always refer to the nominal capacity of the outdoor unit to determine the nominal system capacity. Use Table 9, (page 19) as a guide for acceptable airflow CFM (dependent on air handler cabinet size and nominal capacity of the outdoorunit). NOTE: The CFM values listed in Table 10, (page 20) are not dependent on duct static pressure. The VSHE motor automatically compensates for changes in ductstatic pressure (within the limits of the motor). 3-Speed Units The blower speed is preset at the factory for operation at the same speed for heating and cooling, by using the jumping terminal on the blower motor and connecting it to the desired speed with both the red and black wires connected to the jumping terminal. NOTE: The control board is programmed with a 40 second off delay in the cooling mode for optimum system performance and efficiency. NOTE: DO NOT alter unit wiring. Listen for any unusual Z--,-\ %WAU 1 !ON' noises. Locate the source and correct as needed. To avoid personal injury or property damage, 2. Allow the unit to run for several minutes and then set the make sure the motor leads do not come into thermostat's temperature above room temperature. Verify contact with any uninsulated metal components the blower cycles off with the thermostat, of the unit. System Heating 1. Set the thermostat's system mode to HEAT and the fan mode to AUTO. Increase the thermostat's temperature above room temperature and observe that the blower energizes. Check the air being discharged at the register is warmer than room temperature. 2. Allow the unit to run for several minutes and then set the thermostat's temperature below room temperature. Verify the blower cycles off with the thermostat. Selecting Minimum Electric Heat Airflow The minimum electric heat airflow setting controls the minimum air flow that will be produced whenever electric heater kits are used. When the electric heater kit is energized along with a heat pump, the airflow maybe higher depending on the basic coolinglheat- pump airflow setting. The minimum electric heat airflow is selected by the red blower wire on 3-speed models or setting switches 1, 2, 3, & 4 on B6EM models. B6VM models automatically set the heating speed based on the amount of installed heat. The A/B switch must be set appropriately for the unit cabinet size. For C-sized cabinets, the AIB switch can be set in either position. The remaining 3 HEATswitches have no function. Switch settings are listed in Table 7, (page 18) or Table 10, (page 20). NOTES: • ForB6EM Models,the minimum electric heat airf low setting may be set higher, but must never be set lower than the setting shown in Table 8, (page 19). • Variable speed motor control boards do not support non- electric heat because the heating air flow cannot be set independently. For optimum system performance and comfort, it may be necessary to change the factory set speed. See Table 6, (page 17) for airflow data. To change the blower speed: 1. Disconnect all electrical power to the unit and remove the upper door. 2. Remove the black and red wires from the blower motor jumping terminal. Discard the blower motor jumping terminal. 3. Connect the heating speed wire (red) and the cooling speed wire (black) to the desired blower speed marked on the terminal block of the blower motor. • Terminal 4 = Hi speed • Terminal 5 = Med speed • Terminal 6 = Low speed 4. Replace the upper door and secure it to the unit. 5. Restore power to the unit. High Efficiency Units (Variable & Fixed Speed) IMPORTANT! This air handler has been designed to give the installer maximum flexibilityto optimize system performance, efficiency, and comfort. Because there are so many different ways to set up the air handler it is important to read and follow these directions carefully. B6EM & B6VM air handlers use high efficiency circulating air motors that come in two variations and both are controlled differently. The variable speed motor control board (Figure 18) controls the airflow at a constant CFM when paired with a separate control board. The fixed speed unit has a single integrated control board (Figure 17 (page 26)) that controls the torque of the motor. Before operation, the air handler must be configured to match the unit with the system, system options, and climatic conditions. During normal operation, the motorwill gradually 12 change speeds during start-up, shut down, when thermostat inputs change, and when the duct static pressure changes (vents closed oropened, filter clogging, etc.). The air handler is configured by setting the selector switches and removing jumper connectors. Basic Heating Airflow for Variable & Fixed Speed Fixed & variable speed motor control boards (Figure 17 (page 26) & Figure 18) contain a set of dip switches for setting the blower speed. For 136EM models, pins 1-4 set the speed for heating. For 136VM models, the A/B switch must be set for the appropriate cabinet size (either setting can be used for C-size cabinets). The airflow is set automatically based on the amount of installed heat. To determine the appropriate switch settings for your installation, see Table 7, (page 18), or Table 10, (page 20). Basic Coaling / Heat Pump Airflow for Variable & Fixed Speed The basic cooling/heat-pump airflow is controlled by setting switches 5 - 8 on the motor control board (mounted on the blower). All airflows for other modes of operation (except electric heat) are determined bythis basic setting. FAN ONLY would deliver 50% of the selected coaling airflow. Table 9, (page 19) lists the CFM airflow values recommended for each nominal system capacity. To determine dip switch settings, refer to Table 7, (page 18) for FSHE applications and Table 10, (page 20) for VSHE applications. • When operating in the heat pump mode, a higher basic airflow setting will increase the energy efficiency and capacity but will also decrease the supply air temperature. • For maximum capacity and energy efficiency, select an airflow at or near the top of the range for that nominal capacity. See Table 9, (page 19). • For maximum dehumidification, select an airflow near the middle or bottom of the range for that nominal capacity. Additional information on humidity control can be found in the Dehumidication Options section on page 11. • For thermostats with a dehumidifier output, use a field supplied wire to connect the thermostat's dehumidifier output to the terminal marked DHUM. The thermostat should be set so that the DHUM output should be high (energized) when dehumidification is needed. See also Dehumidification Options section. IMPORTANT! If coil icing is observed, the basic cooling/ heat -pump airflow selected maybe too low. Verify the setting selected is within the range shown in Table 9 and thatthe the system is properly charged. Please refer to the instructions supplied with the outdoor unit. If icing continues to occur, raise the selected airflow one or two steps. NOTE: Variable speed air handlers with SEER ratings higher than 15 are matched with a 2-stage cooling outdoor unit. They are programmed to operate at 75% of the selected airflow while the system is in the to -cool mode and 100% of the selected airflow while in hi -cool mode. Units with an FSHE control scheme (136EM and 5 ton B6BM units) have a control board that includes a 7 segment display to help the installer identify what mode the air handler is running in as well as troubleshooting if the unit is not functioning properly. Table 2, (page 13) contains a list of the codes that may appear on the 7 segment display. The display code will only show what mode the air handler is currently in. There is not a history of fault codes that have occurred in previous operation. TROUBLESHOOTING If the air handler fails to operate, check the following: • Is the electric turned on? • Is the thermostat operating properly? • Are the blower compartment door(s) in place? • Is the air handler disconnect closed? • Has the circuit breaker tripped or the control board fuse burned open? • Are any manual reset switches open? • Is the filter dirty or plugged? • Is the LED on both control boards constantly ON? If not, refer to Table 3 or Table 4 to determine fault condition.

Some of the components and their locations are shown in Figure 12 (page 16). If any component of the air handler must be replaced, use only factory authorized replacement parts specified in the Replacement Parts List provided online. D WARNING: ELECTRICAL SHOCK FIRE OR EXPLOSION HAZARD Failure to follow safety warnings exactly could result in serious injury or property damage. Improper servicing could result in dangerous operation, serious injury, death or property damage. • Before servicing, disconnect all electrical power to the indoor blower. • When servicing controls, label all wires prior to disconnecting. Reconnect wires correctly. • Verify proper operation after servicing. • These maintenance instructions are primarily intended to assist qualified technicians experienced in the proper maintenance and operation of this appliance. • Always reinstall the doors on the air handler after servicing or cleaning/changing the filters. Do not operate the air handler without all doors and covers in place. • Verify that the thermostat is properly installed and is not being affected by drafts or heat from lamps or other appliances. • To achieve the best performance and minimize equipment failure, it is recommended that a yearly maintenance checkup be performed. At a minimum, this check should include the following items: Air Filter(s) - 136 Series Air Handlers are not supplied with a single air filter when shipped from the factory. It is recommended that the filter be cleaned or replaced every 4 to 6 months at a minimum. Newly built or recently renovated homes may require more frequent changing until the construction dust has minimized. Filter sizes shown in Table 5 are available at most local retailers. AWARNING: Never operate the air handler without a filter in place. Dust and lint in the return air can build up on internal components, resulting in loss of efficiency, equipment damage, and possible fire. Filters designed to remove smaller particles such as pollen, may require additional maintenance. Blower Compartment - Dirt and lint can create excessive loads on the motor resulting in higher than normal operating temperatures and shortened service life. It is recommended that the blower compartment be cleaned of dirt or lint that may have accumulated in the compartment or on the blower and motor as part of the annual inspection. CABINET SIZE FILTER SIZE A 12x20x1 B 18x20x1 C 20x20x1 Table 5. Fitter Sizes Blower Fan Wheel - Inspect the blower wheel blades for accumulations of dirt and clean if necessary. Inspectmounting nut for tightness when done. Blower Motor & Assembly - Inspect the blower assembly and motor mounting brackets for tightness and corrosion. Correct deficiencies if necessary. The blower motor contains sealed bearings and under normal operating conditions, no maintenance is necessary for the life of the equipment. REFRIGERANT CHARGING AWARNING: - 1 NITROGEN HEALTH FLAMMABILITY REACTIVITY 9 M1WM81 Hazard 1 Sllght Hazard The evaporator coil is shipped from the factory with a nitrogen charge.
