HOMEOWNER INFORMATION
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.
Ask your dealer to show you where the 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 in your home. Check the filter monthly and
clean or replace it as needed.
Disposable filters should be replaced with a filter of the same
type and size. If you are unsure of the filter you need for
your system, contact your dealer.
Many indoor units are equipped with reusable foam filters.
These filters can be cleaned with a mild soap and water
solution. Rinse the filter thoroughly and let dry completely
before returning to unit or grille.
The filter and all access panels must be in place any
time the unit is in operation.
Some systems are equipped with an electronic air cleaner,
designed to remove the majority of airborne particles from
the air passing through the cleaner. If your system includes
an electronic air cleaner, ask your dealer for maintenance
instructions.
Inspect and clean indoor coil. The indoor evaporator coil
is equipped with a drain pan to collect condensate formed
as the 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 also applies to an auxiliary
drain, if one is installed.
Inspect and clean outdoor coil:
Make sure no obstructions restrict airflow to the outdoor unit.
Leaves, trash, or shrubs crowding the unit can cause it to
work harder and use more energy. Keep shrubbery trimmed
away from the unit and periodically check for debris which
collects around the unit.
The outdoor coil may require frequent cleaning, depending
on environmental conditions. Clean the outdoor coil with an
unpressurized water hose to remove surface contaminants
and debris. 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 (such as pet
urine, cottonwood seeds, etc...).
Turn all electric power to unit OFF at disconnect
switch(es) before performing any maintenance
operations on system. Unit may have multiple power
supplies. Electrical shock could cause personal injury
or death.
