WARNING
Goodman 6
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
WARNING
Installation and repair of this unit should
Goodman 7
be performed ONLY by individuals meeting
the requirements of an "Entry Level Technician,"
at a minimum, as specified by the Air-Conditioning,
Heating and Refrigeration Institute (AHRI). Attempting
to install or repair this unit without such background may
result in product damage, personal injury or death.
CAUTION
Scroll equipped units should never be used to evacuate
Goodman 32
the air conditioning system. Vacuums this low can cause
internal electrical arcing resulting in a damaged or failed
compressor.

  • Page 2: Important Note To The Owner Regarding Product Warranty

    Important Note to the Owner Regarding Installation Clearances Product Warranty Special consideration must be given to the location of the heat pump(s) in regard to structures, obstructions, other units and any/ Your warranty certificate is supplied as a separate document with all other factors that may interfere with air circulation.
  • Page 3: Rooftop Installations

    Rooftop Installations If it is necessary to install this unit on a roof structure, ensure the Situate the unit to permit free unobstructed drainage of the roof structure can support the weight and that proper defrost water and ice. In more severe weather locations, it is consideration is given to the weather-tight integrity of the roof.
  • Page 4: Refrigerant Lines

    REFRIGERANT LINES Mounting the evaporator coil above the heat pump will require an CAUTION inverted loop in the suction line adjacent or near the connection to the evaporator coil. The top of the loop must be slightly higher Goodman 16 than the top of the evaporator coil.
  • Page 5: Burying Refrigerant Lines

    Burying Refrigerant Lines Leak Testing—Nitrogen or Nitrogen-Traced If burying refrigerant lines cannot be avoided, use the following checklist. WARNING Goodman 17 1. Insulate liquid and suction lines separately. 2. Enclose all underground portions of the refrigerant lines in To avoid the risk of fire or explosion, never use oxygen, waterproof material (conduit or pipe) sealing the ends where high pressure air or flammable gases for leak testing of a tubing enters/exits the enclosure.
  • Page 6: Electrical Connections

    If the pressure rises to 1,000 microns or less and remains steady, the system is considered leak-free; proceed to 5,000 start-up. If pressure rises above 1,000 microns but holds steady 4,500 below 2,000 microns, moisture and/or noncondensibles 4,000 may be present or the system may have a small leak.

  • Page 8: System Start-Up

    SYSTEM START-UP NOTES: NOTE: These are not back-seating valves. It is not necessary to force the stem tightly against the rolled lip. Units with crankcase heaters should have the high-voltage power energized for 24 hours prior to start-up. Heat pumps After the refrigerant charge has bled into the system, open the are equipped with a time/temperature defrost control with liquid service valve.
  • Page 9: Fixed Orifice

    System Superheat Outdoor Dry Bulb Indoor Wet Bulb Temperature ºF Temperature ºF Fixed Orifice If the subcooling and superheat are low, adjust TXV to 7ºF to 9ºF superheat. Check subcooling. NOTE: To adjust the superheat, turn the valve stem WARNING clockwise to increase and counterclockwise to decrease.
  • Page 10: Heat Pump-Heating Cycle

    NOTES: Heat Pump—Heating Cycle Do not adjust the charge based on the suction pressure unless there is a gross undercharge. The proper method of charging a heat pump in the heat mode is Check the Schrader ports for leaks and tighten valve by weight with the additional charge adjustments for line size, line cores if necessary.
