Homeowners Information
CAUTION
Before attempting to perform any service or mainte nance, turn the electrical power to unit OFF at discon nect switch.
Cleaning of the outdoor unit's coil should be performed by a licensed professional service technician (or equivalent). 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.
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.
SKeep snow level below the louvered panels to ensure proper performance.
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, soak ers, waste water, etc.) will corrode the surface of steel and aluminum parts, diminish performance and af fect longevity of 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.
NOTE — The filter and all access panels must be in place any time the unit is in operation. If you are unsure about the filter required for your system, call your Lennox dealer for assistance.
1.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 filters should be replaced with a filter of the same type and size.
3.The indoor 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.
