Lennox Heat Pump XP17-060-230-05

Warning: This test requires a fully charged 9V battery and should be performed by trained personnel only.

Is the main (240 volt) power OFF to unit?

Have both wires (brown and black) been removed from the J2 terminal on the fan motor control (A177)?

Is the room thermostat in OFF position (unit in idle mode - no heating or cooling demands)?

Is the main power (240 volt) ON to unit?

Upload a picture of the 9 Volt battery connected to fan motor (B4) plugs.

Is the fan motor running at a reduced fan speed?

If the fan motor does not run, has the fan motor assembly been replaced?

Use a thermocouple or thermistor electronic vacuum gauge that is calibrated in microns. Use an instrument capable of accurately measuring down to 50 microns.

Leak detector must be capable of sensing HFC refrigerant.

When using a high pressure gas such as dry nitrogen to pressurize a refrigeration or air conditioning system, use a regulator that can control the pressure down to 1 or 2 psig (6.9 to 13.8 kPa).

Refrigerant can be harmful if it is inhaled. Refrigerant must be used and recovered responsibly. Failure to follow this warning may result in personal injury or death.

Maintenance and service must be performed by a qualified installer or service agency.

Outdoor coil cleaned and inspected?

All connecting lines, joints and coils visually inspected for oil leaks?

All wiring checked for loose connections?

Correct voltage at unit checked?

Drain holes in coil compartment base inspected and cleaned if necessary?

NOTE - If insufficient heating or cooling occurs, the unit should be gauged and refrigerant charge should be checked.

Sign off on the outdoor unit maintenance

WARNING: This product and/or the indoor unit it is matched with may contain fiberglass wool. Disturbing the insulation during installation, maintenance, or repair will expose you to fiberglass wool dust. Breathing this may cause lung cancer. (Fiberglass wool is known to the State of California to cause cancer.) Fiberglass wool may also cause respiratory, skin, and eye irritation.

Check connecting lines, joints and coil for evidence of oil leaks.

Check condensate line and clean if necessary.

Warning: This maintenance check requires trained personnel with PPE!

Outdoor Coil: It may be necessary to flush the outdoor coil more frequently if it is exposed to substances which are corrosive or which block airflow across the coil (e.g., pet urine, cottonwood seeds, fertilizers, fluids that may contain high levels of corrosive chemicals such as salts)

Outdoor Coil flushed with a water hose?

Outdoor Coil (sea coast) - Moist air in ocean locations can carry salt, which is corrosive to most metal. Units that are located near the ocean require frequent inspections and maintenance.

Inspection and maintenance performed for units near the ocean?

Consult your installing contractor for proper intervals/procedures for your geographic area or service contract.
