CAUTION
Physical contact with metal edges and corners while
applying excessive force or rapid motion can result in
personal injury. Be aware of, and use caution when
working near these areas during installation or while
servicing this equipment.
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.
S
Please contact your dealer to schedule proper
inspection and maintenance for your equipment.
S
Make sure no obstructions restrict airflow to the
outdoor unit.
S
Grass clippings, leaves, or shrubs crowding the unit
can cause the unit to work harder and use more
energy.
S
Keep 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
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
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
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
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.)
