Many indoor units are equipped with re-usable foam filters. These filters can be cleaned with a mild soap and water solution. Rinse the filter thor- oughly and let it dry completely, before it is returned to the unit or grille.

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

Your system may be equipped with an electronic air cleaner which will provide respiratory relief by re- moving up to 90 percent of all airborne particles which pass through it. If it is, ask your dealer to instruct you on its maintenance.

Your indoor evaporator coil is equipped with a drain pan to collect condensate formed as your sys- tem removes humidity from the inside air. Have your dealer show you where the main condensate drain (and auxiliary drain, if applicable) runs and how to check the drain for any obstruction.

It is also very

important to provide

unrestricted airflow to the

outdoor unit. Leaves, trash or shrubs

crowding the unit cause the

outdoor unit

to work harder and use more energy. Keep shrubbery trimmed away from the unit and periodically check for debris which may have collected around the unit.

Lennox Dealers

Nobody knows more about the care and operation of your new Lennox equipment than your Lennox dealer. Your Lennox dealer is your best choice for routine maintenance or service. Lennox’ Quality Dealer Standards program ensures that when you call your Lennox dealer, you can count on prompt, courteous and professional service.

Before the start of each heating and cooling sea- son, the following service checks should be performed by a qualified service technician.

As always, electrical power to the unit must be turned off prior to any unit maintenance.

DThe outdoor and indoor coils should be inspected and cleaned. The outdoor coil may be flushed with a water hose.

NOTE – 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, etc.)

DThe refrigerant lines should be visually inspected and the coils should be checked for leaks.

DWiring should be checked for loose connections.

DVoltage must be checked at the indoor and outdoor units (units operating).

DThe amp-draw at the outdoor fan motor and indoor blower motor should be checked. Values should be compared with those given on unit nameplate.

DIndoor unit filters should be cleaned or replaced.

DThe refrigerant charge should be checked and system pressures should be gauged.

DThe condensate drain line should be checked for free and unobstructed flow and it should be cleaned, if necessary.
