Air Filter
Inspect air filters at least m onthly and replace or clean as
required. Disposable filters should be replaced. W ashable
filters m ay be cleaned by soaking in m ild detergent and
rinsing with cold water. Replace filters with the arrows
pointing in the direction of airflow. Dirty filters are the m ost
com m on cause of poor heating / cooling perform ance and
com pressor failures.

Indoor Coil
If the system has been operated with a clean filter in
place, it should require m inim al cleaning. Use a vacuum
cleaner and soft brush attachm ent to rem ove any
accum ulation of dust from the top and underside of the
finned coil surface. However, perform this m aintenance
only when the coil is com pletely dry.

flow of drainage and clean if necessary.
Condenser Coils
Grass cuttings, leaves, dirt, dust, lint from clothes dryers,
and fall off from trees can be drawn into coils by m ovem ent

Painted Surfaces
For m axim um protection of the unit's finish, a good grade
of autom obile wax should be applied every year. In
geographical areas where water has a high concentration
of m inerals (calcium , iron, sulfur, etc.). It is recom m ended
that lawn sprinklers not be allowed to spray the unit. In
such applications, the sprinklers should be directed away
from the unit. Failure to follow this precaution m ay result
in prem ature deterioration of the unit finish and m etal
com ponents.

In sea coast areas, special m aintenance is required due
to the corrosive atm osphere provided by the high salt
concentration in ocean m ists and the air. Periodic washing
of all exposed surfaces and coil will add additional life to
your unit. Please consult your installing dealer for proper
procedures in your geographic area.
