Sign off on the outdoor coil maintenance

Lennox blower motors are prelubricated and permanently sealed. No more lubrication is needed.

Adjust blower speed for cooling. Measure the pressure drop over the coil to determine the correct blower CFM.

Belt Drive Blowers - Check belt for wear and proper tension.

Check all wiring for loose connections.

Check for correct voltage at unit. (blower operating)

Check amp draw on blower motor.

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

Clean and inspect outdoor coil (may be flushed with a water hose). Ensure power is off before cleaning.

Outdoor unit fan motor is pre-lubricated and sealed. No further lubrication is needed.

Visually inspect all connecting lines, joints and coils for evidence of oil leaks.

Check all wiring for loose connections.

Check for correct voltage at unit (unit operating).

Check amp draw on outdoor fan motor.

Inspect drain holes in coil compartment base and clean it necessary.

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

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.
