Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the
unit before cleaning to prevent shock 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.
• Remove filter by sliding out from the right-hand side.
• Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thor-
oughly. Gently shake excess water from the filter. Be sure filter is thoroughly dry before
replacing.
• Or, instead of washing you may vacuum the filter clean.
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.
• Plug in air conditioner.
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.
Care and Cleaning
Normal Sounds
When your air conditioner is operating normally, you may hear
sounds such as:
■ Droplets of water hitting the condenser, causing a pinging or
clicking sound. The water droplets help cool the condenser.
■ Air movement from the fan.
■ Clicks from the thermostat cycle.
■ Vibrations or noise due to poor wall or window construction.
■ A high-pitched hum or pulsating noise caused by the modern
high-efficiency compressor cycling on and off.
Cleaning the Front Panel
1. Unplug air conditioner or disconnect power.
2. Clean front panel with a soft, damp cloth.
3. Air dry front panel completely.
4. Plug in air conditioner or reconnect power.
Repairing Paint Damage
Check once or twice a year for paint damage. This is very
important, especially in areas near oceans or where rust is a
problem. If needed, touch up with a good grade enamel paint.
NOTE: To reduce paint damage during the winter, install a heavy
duty cover over air conditioner cabinet. For information on
ordering a heavy-duty cover, see “Accessories.”
Annual Maintenance
Your air conditioner needs annual maintenance to help ensure
steady, top performance throughout the year. Call your local
authorized dealer to schedule an annual checkup. The expense
of an annual inspection is your responsibility.
