CLEANING AND MAINTENANCE
Air Filter Cleaning
Cabinet Cleaning
Winter Storage
The air fi lter should be checked at least once every two 
weeks to see if cleaning is necessary. Trapped particles 
in the fi lter can build up and cause an accumulation of 
frost on the cooling coils and reduce performance.
• Grasp the fi lter by the center and pull up and out.
• Wash the fi lter using warm water. Rinse fi lter 
thoroughly.
•  Gently shake excess water from the fi lter. Be sure 
the fi lter is thoroughly dry before replacing.
•  Instead of washing, you may also vacuum the fi lter 
clean rather than washing.
•  Be sure to unplug the air conditioner to prevent shock or fi re 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.
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.
  CAUTION
Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to 
prevent shock or fi re hazards.
Never use hot water over 104°F (40°C) to clean the air fi lter. Never attempt to operate the unit without the 
air fi lter.
