around the temperature point set by you.

• If the AUTO mode is uncomfortable, you can select desired conditions
manually.

■ SLEEP OPERATION

• When you push SLEEP button during cooling, heating (cooling only
type without), or AUTO operation, the air conditioner will automatically
increase (cooling) or decrease (heating) 1°C per hour. The set
temperature will be steady 2 hours later.

• The fan speed will be automatically controlled.

■ DRYING OPERATION

• The dry mode will automatically select the drying operation based
on the difference between the set temperature and the actual
room temperature.

• The temperature is regulated while dehumidifying by repeating turning
on and off of the cooling operation or fan only. The fan is low.

To achieve optimal performance, Please note the following:

• Adjust the air flow direction correctly so that it is not directed on people.

• Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature levels.

• Close doors and windows on COOL or HEAT modes, or performance may be reduced.

• Use TIMER ON button on the remote controller to select a time you want to start your air conditioner.

• Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air
conditioner may stop running.

• Clean the air filter periodically, otherwise cooling or heating performance may be reduced.

• Do not operate unit with horizontal louver in closed position.

PREPARATION BEFORE INSTALLATION
