Air Conditioner Features (general)
Air Conditioner Features (RAC-WK05 only)
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
• 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.
WARNING
To reduce the risk of fire, electrical shock, or injury to people or property, read the
SAFETY PRECAUTIONS before operating this appliance.
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 ow (see Air Directional Louvers).
4. Once the room feels cooled, adjust the thermostat to the setting you nd most comfortable.
5. Make sure that the air ow inside and outside are not obstructed by anything.
NOTE
Always wait 3 minutes when turning unit and then on again, or when changing from cool to fan and
back to cool. This prevents compressor from overheating and possible tripping.

Leve r
Air Direction
Air Directional Louvers
The louvers will allow you to direct the air ow Left or Right, or Up
and Down 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.

Before you begin, thoroughly familiarize yourself with the control panel as shown below and all its
functions, then follow the symbol for the functions you desire. The unit can be controlled by the unit
control alone or with the remote.
COOL MODE
The desired cool setting is selected by rotating the knob to the right
to the desired position.
HIGH COOL has maximum cooling eect and airow.
LOW COOL has minimum cooling eect and airow.
FAN MODE
Rotate the knob to the left to select your choice of fan speeds for air
circulation.
NOTE: When selecting a fan speed, the compressor will not run.
THERMOSTAT
The thermostat is used to set the desired room temperature when
the unit is being operated in the COOL MODE.
To set the desired room temperature, rotate the thermostat switch
to the desired setting. After the set temperature is achieved the
thermostat will automatically start and stop the compressor in
order to maintain the desired set temperature.
Rotate the thermostat selector clockwise for higher cool settings.
Higher cool settings will provide lower room temperature. Rotate
the thermostat selector counter clockwise for lower cool settings.
Lower cool settings will provide higher room temperature.
