Indoor Coil

1.Clean coil if necessary.

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

3.Check condensate line and clean if necessary.

HOMEOWNER

Cleaning of the outdoor unit’s coil should be performed by a trained service technician. Contact your dealer and set up a schedule (preferably twice a year, but at least once a year) to inspect and service your outdoor unit. The following maintenance may be performed by the homeowner.

Manual background IMPORTANT

Sprinklers and soaker hoses should not be installed where they could cause prolonged exposure to the outdoor unit by treated water. Prolonged exposure of the unit to treated water (i.e., sprinkler systems, soakers, waste water, etc.) will corrode the surface of steel and aluminum parts and diminish performance and longevity of the unit.

Outdoor Coil

The outdoor unit must be properly maintained to ensure its proper operation.

SPlease contact your dealer to schedule proper inspection and maintenance for your equipment.

SMake sure no obstructions restrict airflow to the outdoor unit.

SGrass clippings, leaves, or shrubs crowding the unit can cause the unit to work harder and use more energy.

SKeep shrubbery trimmed away from the unit and periodically check for debris which collects around the unit.

Cleaning of the outdoor unit’s coil should be performed by a trained service technician. Contact your dealer and set up a schedule (preferably twice a year, but at least once a year) to inspect and service your outdoor unit.

Routine Maintenance

In order to ensure peak performance, your system must be properly maintained. Clogged filters and blocked airflow prevent your unit from operating at its most efficient level.

1.Air Filter Ask your Lennox dealer to show you where your indoor unit’s filter is located. It will be either at the indoor unit (installed internal or external to the cabinet) or behind a return air grille in the wall or ceiling. Check the filter monthly and clean or replace it as needed.

2.Disposable Filter Disposable filters should be replaced with a filter of the same type and size.

NOTE If you are unsure about the filter required for your system, call your Lennox dealer for assistance.

3.Reusable Filter Many indoor units are equipped with reusable foam filters. Clean foam filters with a mild soap and water solution; rinse thoroughly; allow

filter to dry completely before returning it to the unit or grille.

NOTE The filter and all access panels must be in place any time the unit is in operation.

4.Indoor Unit The indoor unit’s evaporator coil is equipped with a drain pan to collect condensate formed as your system removes humidity from the inside air. Have your dealer show you the location of the drain line and how to check for obstructions. (This would also apply to an auxiliary drain, if installed.)

Thermostat Operation

See the thermostat homeowner manual for instructions on how to operate your thermostat.

Heat Pump Operation

Your new Lennox heat pump has several characteristics that you should be aware of:

SHeat pumps satisfy heating demand by delivering large amounts of warm air into the living space. This is quite different from gas- or oil-fired furnaces or an electric furnace which deliver lower volumes of considerably hotter air to heat the space.

SDo not be alarmed if you notice frost on the outdoor coil in the winter months. Frost develops on the outdoor

coil during the heating cycle when temperatures are below 45°F (7°C). An electronic control activates a defrost cycle lasting 5 to 15 minutes at preset intervals to clear the outdoor coil of the frost.

SDuring the defrost cycle, you may notice steam rising from the outdoor unit. This is a normal occurrence. The thermostat may engage auxiliary heat during the defrost cycle to satisfy a heating demand; however, the unit will return to normal operation at the conclusion of the defrost cycle.

Extended Power Outage

The heat pump is equipped with a compressor crankcase heater which protects the compressor from refrigerant slugging during cold weather operation.

If power to your unit has been interrupted for several hours or more, set the room thermostat selector to the EMERGENCY HEAT setting to obtain temporary heat without the risk of serious damage to the heat pump.

In EMERGENCY HEAT mode, all heating demand is satisfied by auxiliary heat; heat pump operation is locked out. After a six-hour compressor crankcase warm-up period, the thermostat can be switched to the HEAT setting and normal heat pump operation may resume.

Preservice Check

If your system fails to operate, check the following before calling for service:

SVerify room thermostat settings are correct.

SVerify that all electrical disconnect switches are ON.

SCheck for any blown fuses or tripped circuit breakers.

SVerify unit access panels are in place.

SVerify air filter is clean.

SIf service is needed, locate and write down the unit model number and have it handy before calling.
