- In this mode, the fan speed cannot be adjusted as it’s automatically controlled according to temperature setting and room temperature.

To operate on Fan Only:

- Use this function only when cooling is not desired, such as for room air circulation or to exhaust stale air (on some models). (Remember to open the vent during this function, but keep it closed during cooling for maximum cooling efficiency.) You can choose any fan speed you prefer.

- During this function, the display will show the actual room temperature, not the set temperature as in the cooling mode. - In Fan Only mode, the temperature is not adjusted.

To operate on Dry mode:

CARE AND CLEANING

Air Filter Cleaning

Models RAC-WK15 / 18

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 the filter by sliding it out from the righthand side. (RAC-WK05 only)

• Push the vent handle to the Vent Closed position (where applicable).

• Open the front panel.

• Grasp the filter by the center and pull up and out.

• Wash the filter using liquid dishwashing detergent and warm water. Rinse filter thoroughly.

• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.

• You may also vacuum the filter clean rather than washing.

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 cleansers, 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.
