once every two weeks to see if cleaning is
necessary. Trapped particles in the filter
can build up and cause an accumulation
of frost on the cooling coils and reduce
performance.
• Grasp the filter by the center and pull
up and out.
• Wash the filter using warm water. Rinse
filter thoroughly.
• 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 cleansers, wax, or polish on the air conditioner.
• Be sure to wring excess water from the cloth before wiping around the controls.
Excess water in or around the controls will cause damage to the air conditioner.
• Plug in air conditioner.
Care and
Cleaning
CAUTION
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the
unit before cleaning to prevent shock or fire hazards.
NOTICE
Never use hot water over 104°F (40°C) to clean the air filter. Never attempt to
operate the unit without the air filter.
If you plan to store the air conditioner during the winter, remove it carefully from the
window according to the installation instructions. Be careful not to spill any potentially
standing water from the unit’s base pan. If water is present, carefully drain it. Cover
the unit with plastic or return it to the original carton.
• Gently shake excess water from the filter. Be sure the filter is thoroughly dry
before replacing.
• Instead of washing, you may also vacuum the filter clean rather than washing.
