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
To begin operating the air conditioner, follow these steps:
1. Set the temperature to the coldest setting.
2. Set the control to HIGH COOL.
3. Adjust the louver for comfortable air ow (see Air Directional Louvers).
4. Once the room feels cool, adjust to the temperature you nd most comfortable.
5. Make sure that the air ow inside and outside are not obstructed.
Air Directional Louvers
The louvers will allow you to direct the air 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 ow
UP/DOWN as needed (RAC-WK08/10/12K only).
Levers
Air Direction
• The 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.
Always wait 3 minutes when turning the unit o and then on again, or when changing from cool to
fan and back to cool. This prevents damage from occurring to the compressor.
To reduce the risk of fire, electrical shock, or injury to people or property, read the SAFETY
PRECAUTIONS before operating this appliance.
