Care & Cleaning
Air Filter Cleaning
CAUTION
Be sure to turn off the unit and unplug it
from the outlet before cleaning to prevent
electric shock or fire hazards. Clean the unit
occasionally to keep it looking new.
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. Follow
the instructions below for how to gain access to
the filter and how to clean it:
• Push the vent handle to the Vent Closed
position (where applicable). Then, open the
front panel.
• Take the filter by the center, and pull up and out.
• Wash the filter using liquid dishwashing detergent
and warm water. Then, rinse the filter thoroughly.
Gently shake any excess water from the filter. Ensure
the filter is thoroughly dry before replacing. Instead
of washing, you could also vacuum the filter clean.
NOTE: Never use hot water, above 104°F (40°C), to
clean the air filter. Never attempt to operate
the unit without the air filter installed.
Cabinet Cleaning
Be sure to unplug the air conditioner before
cleaning the cabinet in order to prevent electric
shock or fire hazard. The cabinet and front of the
unit may be dusted with an oil-free cloth, or washed
with a cloth damp with a solution of warm water
and mild liquid dishwashing detergent. Rinse
thoroughly and then wipe dry. Never use harsh
cleaners, wax, or polish on the front of the cabinet.
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. Once finished, plug the air conditioner
back into the outlet.
Winter Storage
If you plan to store the air conditioner during
the winter, remove it carefully from the window
according to the installation instructions. Cover
it with plastic or return it to the original
carton/box.
