CARE AND CLEANING
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit
before cleaning to prevent chock or fire hazards.

Air Filter Cleaning
The air filter should be checked at least once a
month to see if cleaning is necessary. Trapped
particles in the filter can build up and cause an
accumulation of frost on the cooling coils.
Push the vent handle to the Vent Closed position
(where applicable).
Open the front panel.
Grasp the filter, pull up and out.
Wash the filter using liquid dishwashing deter-
gent and warm water. Rinse filter thoroughly.
Gently shake excess water from the filter. Be
sure the filter is thoroughly dry before replacing.
Or, instead of washing you may vacuum the
filter clean.
Note: Never use hot water over 40 C (104 F) to
clean the air filter. Never attempt to operate the
unit without the air filter.
Cabinet Cleaning
Be sure to unplug the air conditioner to prevent
shock or fire hazard. The cabinet and front may
be dusted with an oil-free cloth or washed with
a cloth dampened in a solution of warm water
and mild liquid dishwashing detergent. Rinse
thoroughly and wipe dry.
Never use harsh cleaners, wax or polish on the
cabinet front.
Be sure to wring excess water from the cloth before
wiping around the controls. Excess water in or around
the controls may cause damage to the air conditioner.
