WARNING Goodman 98 Connecting unit ductwork to unauthorized heat producing devices such as a fireplace insert, stove, etc., may result in property damage, fire, carbon monoxide poisoning, explosion, personal injury or death. WARNING This product contains or produces a chemical or chemicals which may cause serious illness or death and which are known to the State of California to cause cancer, birth defects or other reproductive harm.
CODES AND REGULATIONS The WPC/WGPH M-series air conditioners and heat pumps are designed for outdoor use only. WGPH M-Series is available in cooling capacities of 2, 2¹⁄₂, 3, 3¹⁄₂, 4 and 5 nominal tons of cooling. WPC M-Series is available in cooling capacities of 2, 3 and 4 nominal tons of cooling. Optional field-installed heat kits are available in 5, 8, 10, 15 and 20 kW. The units can be easily installed in manufactured or modular homes with existing highstatic ductwork.
Roof Curb Installation Rooftop Preinstallation Details Ensure that the roof is weather tight and allows proper drainage of condensation. ■ Use steel or treated wood beams as unit support for load distribution. NOTE: To ensure proper condensate drainage, unit must be installed in a level position. ■ To avoid possible property damage or personal injury, the roof must have sufficient structural strength to carry the weight of the unit(s) and snow or water loads as required by local codes.
IMPORTANT: If you are using bottom discharge with roof curb, ductwork should be attached to the curb prior to installing the unit. Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end. Rigging Airflow Conversion Units can easily be converted from horizontal to down-discharge airflow delivery.
NOTE: Filters must have adequate face area for the rated quantity of the unit. See the Air Delivery Table for the recommended filter size. Size the filters in accordance with their manufacturer recommendations. Throwaway filters must be sized for a maximum face velocity of 300 ft per minute.
■ High Voltage Wiring ■ ■ From the unit disconnect to unit, the smallest wire size allowable may be used for the ampacity, as the Disconnect must be in sight of the unit. Single Phase—2 leads should be connected to terminals L1 and L2 in the electrical control section, using wire sizes specified in the wiring diagram.

Start-up Procedure—Heat Pump 1. Check that the cooling mode for the heat pump is working properly according to the procedure listed in the “Start-up Procedure and Checklist—Cooling Cycle” section. ■ The reversing valve is energized when the thermostat is placed in the cooling position. ■ A clicking sound should be noticeable from the reversing valve. ■ By lowering the temperature setting to call for cooling, the contactor is energized. ■ The compressor, blower and fan should then be running. 2.
Defrost Control The Defrost control provides time/temperature initiation and termination of the defrost cycle. When a defrost cycle is initiated, the defrost control shifts the reversing valve to Cooling mode, stops the outdoor fan and brings on supplemental heat. Normally, a defrost cycle will take only 2 to 3 minutes unless the system is low on refrigerant charge or outdoor conditions are severe (windy and cold). The defrost control also provides for a 3-minute off-cycle compressor delay.
Since the temperature of the refrigerant in the outdoor coil on the heating cycle is generally below the freezing point, frost forms on the surfaces of the outdoor coil under certain weather conditions related to temperature and relative humidity. Therefore, it is necessary to reverse the flow of the refrigerant to provide hot gas in the outdoor coil to melt the frost accumulation. This is accomplished by reversing the heat pump to the cooling cycle.
AIRFLOW MEASUREMENT AND ADJUSTMENT After reviewing the “Ductwork” section in “Circulating Air and Filters,” proceed with the airflow measurements and adjustments. The unit blower curves (see Specification Sheets) are based on the external static pressure (ESP per in./W.C.). The duct openings on the unit are considered internal static pressure.

CHARGE VERIFICATION Determine Superheat 1. Read suction pressure. 2. Determine Saturated Suction Temperature from tables or pressure gauge saturated temperature scale (R-410A). 3. Read suction line temperature. 4. Use the following formula to determine Superheat.
EXPANSION VALVE (TXV) SYSTEM Single Speed Application—WPC45 1. Purge the gauge lines. 2. Connect the service gauge manifold to the access fittings. Run the system for at least 10 minutes to allow the pressure to stabilize. 3. Temporarily install a thermometer on the liquid (small) line near the liquid line access fitting with adequate contact and insulate for best possible reading. 4. Check subcooling and superheat.
Choose the heat kit that fits the application for the specific installation. Permanently mark the unit’s nameplate with the model being installed. High and low voltage connections are detailed in the heat kit instructions. Indoor blower motor speed tap selection may need to be modified to accommodate normal continuous operation to prevent a nuisance trip. See the following charts. These few steps will help to keep the product up time to a maximum.
TROUBLESHOOTING CHART Symptom Possible Cause High head—low suction ■ Restriction in liquid line or flowrator ■ Remove or replace with proper size flowrator. High head—high or normal suction ■ Dirty condenser coil Overcharged Condenser fan not running ■ Clean coil. Correct system charge. Repair or replace condenser fan.
