Homeowner Information − 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.
IMPORTANT
Turn off electrical power to the unit at the
disconnect switch before performing any
maintenance. The unit may have multiple power
supplies.
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 re-
move 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 in-
side 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.)
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 perfor-
mance and longevity of the unit.
6.
Outdoor Unit
Make sure no obstructions restrict
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
collects around the unit.
