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.
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. Electronic Air Cleaner Some systems are
equipped with an electronic air cleaner, designed to remove airborne particles from the air passing through the cleaner. If your system is so equipped, ask your dealer for maintenance instructions.
5.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 ComfortSense® 7000 thermostat homeowner manual for instructions on how to operate your thermostat.

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.
