Air Conditioner Features (general)

This air conditioner is designed to be operated under the following conditions:

Cooling Operation

• Outdoor temp.: 64 ~ 109°F / 18 ~ 43°C
• Indoor temp.: 62 ~ 90°F / 17 ~ 32°C

NOTES

• he relative humidity of room should be less than 80%. If the unit is used in a condition with a relative humidity over 80%, there will be condensed water on the surface of the unit.
• Performance may be reduced outside of these operating temperatures.

Air Conditioner Features (RAC-WK05 only)

NOTE: Always wait 3 minutes when turning the unit off and then on again, or when changing from cool to fan and back to cool. This prevents compressor from overheating and possible tripping.

To begin operating the air conditioner, follow these steps:

1. Set the thermostat to the highest number (coldest or cooler setting).
2. Set the selector control to the highest COOL setting.
3. Adjust the louver for comfortable air flow (see Air Directional Louvers).
4. Once the room feels cooled, adjust the thermostat to the setting you find most comfortable.
5. Make sure that the air flow inside and outside is not obstructed.

Air Directional Louvers

The louvers will allow you to direct the air fl ow Left or Right, or Up and Down (optional on some models) throughout the room as needed.

Move the Levers from side to side until the desired LEFT/RIGHT direction is obtained.

You can also move the LEFT lever to adjust air fl ow UP/DOWN as needed

CARE AND CLEANING

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 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 it 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 it.
• 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.
