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 cooling coils.

• Grasp the filter by the center and pull up and out.
• Wash the filter using liquid dishwashing detergent and warm water. Rinse the filter thoroughly.
  • Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.
• You may vacuum the filter clean instead of washing it.

Note: Never use hot water over 40^ ( 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 hazards The cabinet and front may be dusted with an oil-free cloth or washed with a cloth moistened with 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.
• Plug in air conditioner.

Winter Storage

- If you plan to store the air conditioner during winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or store it in its original box.

NOTE: To prevent rust or electrical connections from being damaged, store the air conditioner in an upright position and in a dry place.
