Operation; Start-Up Procedure And Checklist; Heat Pump Start-Up Procedure - Goodman GPC 13 SEER H Series Installation Instructions Manual

1. For branch circuit wiring (main power supply to unit
disconnect), the minimum wire size for the length of the
run can be determined from Table 4 using the circuit
ampacity found on the unit rating plate. From the unit
disconnect to unit, the smallest wire size allowable in Table
4 may be used for the ampacity, as the Disconnect must
be in sight of the unit.
2. Wire size based on 60° C rated wire insulation and 30° C
Ambient Temperature (86° F).
3. For more than 3 conductors in a raceway or cable, see the
N.E.C. for derating the ampacity of each conductor.
CHARGING INSTRUCTIONS
For Export R-22 Models shipped without factory
refrigerant charge.
NOTE: Units manufactured after January 1, 2010 are shipped
without refrigerant and are pressurized with a nitrogen
holding charge of 80 PSI. This charge must be removed
and the unit evacuated prior to charging. Follow the steps
below to properly remove the nitrogen holding charge,
evacuate and charge the system.
1. Release holding charge by installing manifold gauges to
the high and low side access fittings and opening
manifold.
2. Evacuate to 250 microns. Close the valve to vacuum pump
and watch the rate of rise. If vacuum does not rise above
1500 microns in 3 to 5 minutes, system can be considered
properly evacuated. If the gauge continues to rise and
levels off at about 1500 microns, moisture and non-
condensables are still present. If the gauge continues to
rise, a leak is present. Repair the leak and re-evacuate.
3. Charge by weighing in the refrigerant charge, per the
following table.

3. Turn on the electrical supply at the disconnect.
4. Turn the fan switch to the "ON" position. The blower should
operate after a 7 second delay.
5. Turn the fan switch to "Auto" position. The blower should
stop after a 65 second delay.
6. Slowly lower the cooling temperature until the unit starts.
The compressor, blower and fan should now be operating.
Allow the unit to run 10 minutes, make sure cool air is
being supplied by the unit.
7. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to run for
65 seconds.
8. Turn the thermostat system switch to "OFF" and disconnect
all power when servicing the unit.

Heat Pump Start-Up Procedure

9. Check the cooling mode for the heat pump in the same
manner as above. 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. After the cooling mode is checked
out, turn the thermostat system switch to "OFF".
10. Turn the thermostat system switch to "HEAT" and fan switch
to "AUTO".
11. Slowly raise the heating temperature setting. When the
heating first stage makes contact, stop raising the
temperature setting.. The compressor, blower and fan
should now be running with the reversing valve in the de-
energized (heating) position. After giving the unit time to
settle out, make sure the unit is supplying heated air.
12. If the out door ambient is above 80°F, the unit may trip on
its high pressure cut out when on heating. The compressor
should stop. The heating cycle must be thoroughly
checked, so postpone the test to another day when
conditions are more suitable but-DO NOT FAIL TO TEST.
If the out door ambient is low and the unit operates properly
on the heating cycle, you may check the pressure cutout
operation by blocking off the indoor return air until the unit
trips.
13. If unit operates properly in the heating cycle, raise the
temperature setting until the heating second stage makes
contact. Supplemental resistance heat, if installed should
now come on. Make sure it operates properly.
NOTE: If outdoor thermostats are installed the outdoor
ambient must be below the set point of these thermostats
for the heaters to operate. It may be necessary to jumper
these thermostats to check heater operation if outdoor
ambient is mild.
14. For thermostats with emergency heat switch, return to step
11. The emergency heat switch is located at the bottom of
the thermostat. Move the switch to emergency heat. The
heat pump will stop, the blower will continue to run, all
heaters will come on and the thermostat emergency heat
light will come on.
