These surfacesare the entire length of the wrapper and areas between the uppertie plate, upper and lower access panels. Check that the upperaccess panel breaker insert gasket is intact and that the flowratorgasket is installed on the lower access panel. An additional drainhole cover is required.Install Condensate DrainCAUTIONIf secondary drain is not installed, the secondary accessmust be plugged. Goodman 2The air handler is provided with ³⁄₄" (1.9 cm) NPT condensatedrain connections.A field-fabricated secondary drain pan, with a drainpipe to theoutside of the building, is required in all installations over afinished living space or in any area that may be damaged byoverflow from the main drain pan. In some localities, local codesmay require a secondary drain pan for any horizontal installation.Make sure the air handler is level so that the drain pan will emptycompletely.1. Remove the appropriate drain knockouts. See “InstallationConfigurations.” You may need to remove the indoor coilassembly from the cabinet.2. Remove any web from inside any threaded drain pan hole towhich a drain line is to be connected. Gently remove the webso as not to damage the coil.7

3. Connect the primary drain line connection to the primarydrain pan connection. The primary drain connection is flushwith the bottom of the inside of the pan. The secondaryconnection is raised above the bottom of the inside of thepan.NOTE: When making drain fitting connections to the drainpan, hand tighten. Using a sealant is recommended.Overtightening the fittings can split connections on the drainpan.4. Secondary drain connections, if used, should be connectedto a separate drainage system. Run the secondary drain lineto a place where the occupant would notice water comingfrom the secondary drain.5. Install a 3" (7.6 cm) trap in both the primary and secondarydrain lines as close to the unit as practical. Make sure the topof the trap is below the connection to the drain pan to allowcomplete drainage of the pan.NOTE: Horizontal runs must also have an anti-siphon air vent(standpipe) installed ahead of the horizontal run. See “TypicalCondensate Drain Connection” in this section. An extremelylong horizontal run may require an oversized drain line toeliminate the trapping of air.Typical Condensate Drain Connection(Secondary Drain Not Shown)3. Correct any leaks found.Install DuctworkIMPORTANT:■ Install the ductwork in accordance with NFPA 90B Standardfor the Installation of Warm Air Heating and Air-ConditioningSytems (latest edition) and any local codes.■ Connect the supply air duct to the flange on top of the unit. Ifan isolation connector is used, it must be nonflammable.■ A return air duct system is recommended. If the unit isinstalled in a confined space or closet, the entire duct crosssectional area must meet the minimum return air free area.Verify Orifice Size1.

For most installations with matchingapplications, no change to the flowrator piston is required.However, in mix-matched applications, a flowrator piston changemay be required. See the piston kit chart or consult your localdistributor for details regarding mix-matched piston sizing. If themix-match application requires a different piston size, change thepiston in the flowrator on the indoor coil before installing the coiland follow the procedure shown below.IMPORTANT: Torch heat required to braze tubes of various sizesis proportional to the size of the tube. Tubes of smaller sizerequire less heat to bring the tube to brazing temperature beforeadding brazing alloy. Applying too much heat to any tube canmelt the tube. Service personnel must use the appropriate heatlevel for the size of the tube being brazed.NOTE: The use of a heat shield when brazing is recommended toavoid burning the serial plate or the finish on the unit. Heat trap orwet rags should be used to avoid damage to heat-sensitivecomponents such as service valves and TXV valves.1. Loosen the ¹³⁄₁₆" nut one turn only to allow high pressuretracer gas to escape. No gas indicates a possible leak.2. After the gas has escaped, remove the nut and discard theblack or brass cap.3.

When using thesetables for this purpose, set the room thermostat to maximumheat and allow the system to reach steady state conditions.Insert 2 thermometers, one in the return air and one in the supplyair. The temperature rise is the supply air temperature minus theroom air temperature.Use HKR specification sheets to determine the HKR available fora given air handler.Voltage Correction =96 (230 Supply Volts)= 92 (220 Supply Volts)= 87 (208 Supply Volts)1.08 = ConstantCFM =Measured Airflow11

Set the thermostat to FAN ON.2. The indoor blower should come on.Check Electric Heater (If Used)1. Set the thermostat to call for auxiliary heat (approximately 5°F[-15ºC] above ambient temperature). The indoor blower andauxiliary heat should come on together. Allow a minimum of3 minutes for all sequencers to cycle on.2. Set the thermostat so it does not call for heat. Allow up to5 minutes for all sequencers to cycle off.Check AirflowCooling Blower Speed■ For proper cooling operation, the airflow through the indoorcoil should be between 350 and 450 CFM per ton of coolingcapacity (or 350 to 450 CFM per 12,000 Btu/h) based on therating of the outdoor unit.■ The cooling blower speed is factory-configured to provide thecorrect airflow for an outdoor unit that matches the maximumcooling capacity rating of the air handler.■ If the outdoor unit is smaller than the maximum coolingcapacity rating for the air handler, the cooling blower speedmay need to be changed. Refer to the Blower PerformanceChart.IMPORTANT: The cooling blower speed must be set to provide aminimum of 350 CFM airflow per ton (1,200 Btu/h) of outdoorcooling capacity.WAHMV MotorWARNINGHIGH VOLTAGE!DisconnectGoodmanALL power6before servicing.Multiple power sources may be present.Failure to do so may cause property damage,personal injury or death.This section references the operation characteristics of theWAHMV model motor only. The ECM control board is factory-setwith DIP Switch 4 in the “ON” position and all other DIP switchesin the “OFF” position. For most applications, this setting is to bechanged according to the electric heat size and the outdoor unitselection.The WAHMV product uses a General Electric ECM TM motor. Thismotor provides many features not available on the traditionalPSC motor. These features include:■ Improved Efficiency■ Constant CFM■ Soft Start and Stop■ Improved Humidity ControlMotor Speed AdjustmentEach ECM TM blower motor has been preprogrammed foroperation at 4 distinct airflow levels when operating in cooling,heat pump heating, backup heating (electric heating) and backupplus heat pump heating. Each mode has 4 levels to deliverdifferent airflow CFM [L/s]. The adjustment is performed bychanging the DIP switch(es) either to an “OFF” or “ON” position.21

DIP Switch FunctionsThe WAHMV air handler motor has an electronic control thatcontains an 8-position DIP switch. The function of these DIPswitches are shown in the following chart.DIP Switch Number123 N/AFunctionElectric Heat4 Indoor Thermostat5678CFM DeliveryThe following tables show the CFM output for DIP switchcombinations 1, 2, 5, 6, 7 and 8.DIP Switch Configurations for Electric HeatCooling and Heat Pump CFMCFM Trim AdjustSwitch Switch Emergency Heat PumpModel 1 2 7 8(Electric)Heatwith BackupHeatWAHMV1830 Off Off Off Off 1,100 1,210On Off Off Off 890 935DIP Switch Configurations for Cooling and Heat PumpSwitch Switch NominalCooling5 6 7 8 Tonnage CFMWAHMV1830 Off Off Off Off 2.5 1,100WAHMV3137WAHMV4260On Off Off Off 2 800Off On Off Off 1.5 600Off Off Off Off 5 1,800On Off Off Off 4 1,580Off On Off Off 3.5 1,480On On Off Off 3 1,200On On Off On 2.5 1,020Thermostat—Fan Only ModeDuring Fan Only Mode operation, the CFM output is 30% of thecooling setting.CFM Trim AdjustMinor adjustments can be made through the DIP switchcombination of 7 and 8.

SEQUENCE OF OPERATIONCooling—Cooling Only or Heat PumpWhen the thermostat calls for cooling, the circuit between R andG is completed, and the blower relay is energized. The normallyopen contacts close, causing the indoor blower motor to operate.The circuit between R and Y is also completed; this circuit closesthe contactor in the outdoor unit starting the compressor andoutdoor fan motor. Circuit R and O energizes the reversing valve,switching it to the cooling position. (The reversing valve remainsenergized as long as selector switch is in the COOL position.)Heating—Electric Heat OnlyWhen the thermostat calls for heat, the circuit between R and Wis completed, and the heat sequencer relay is energized. A timedelay follows before the heating elements and the indoor blowermotor come on. Units with a second heat sequencer relay can beconnected with the first sequencer to W on the thermostatsubbase or connected to a second stage on the subbase.Heating—Heat PumpWhen the thermostat calls for heat, the circuits between R and Yand R and G are completed. Circuit R-Y energizes the contactorstarting the outdoor fan motor and the compressor. Circuit Rand G energizes the blower relay starting the indoor blowermotor.If the room temperature should continue to fall, the circuitbetween R and W 1 is completed by the 2 nd stage heat roomthermostat. Circuit R-W 1 energizes a heat sequencer relay. Thecompleted circuit will energize supplemental electric heat (ifavailable). Units with a second heat sequencer relay can beconnected with the first sequencer to W 1 on the thermostat orconnected to a second heating stage W 2 on the thermostatsubbase.AIR HANDLER MAINTENANCEWARNINGHIGH VOLTAGE!Goodman 6Disconnect ALL power before servicing.Multiple power sources may be present.Failure to do so may cause property damage,personal injury or death.IMPORTANT: Do not operate system without a filter. A filter isrequired to keep excessive dirt and dust from the coil, blower,and internal parts. See “Installation Configurations” for thelocation of the filter in the unit cabinet and the service panelgiving access to the unit filter. The filter is placed in the supply airreturn duct by the installer.■■■■■Inspect air filters at least once a month and replace or cleanas required. Dirty filters are the most common cause ofinadequate heating or cooling performance.Replace disposable filters. Cleanable filters can be cleanedby soaking in mild detergent and rinsing with cold water.Install new/clean filters with the arrows on the side pointing inthe direction of airflow.Do not replace a cleanable (high velocity) filter with adisposable (low velocity) filter unless the return air system isproperly sized for it.If water should start coming from the secondary drain line, aproblem exists which should be investigated and corrected.Contact a qualified person.ASSISTANCE OR SERVICEIf you need further assistance, you can write to the belowaddress with any questions or concerns:Whirlpool ® Home Cooling and Heating14610 Breakers DriveJacksonville, FL 32258AccessoriesTo order accessories, contact your Whirlpool ® Home Cooling andHeating dealer.Please include a daytime phone number in your correspondence.23
