OPTIMAL OPERATION

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 louvre in closed position.
AUTOMATIC OPERATION
When you set the air conditioner in AUTO mode, it will
automatically select cooling, heating(cooling/heating
models only), or fan only operation depending on what
temperature you have selected and the room temperature.
The air conditioner will control room temperature
automatically round the temperature point set by you.
If the AUTO mode is uncomfortable, you can select
desired conditions manually.
ECONOMIC OPERATION
When you push ECONO button during cooling, heating
(cooling only type without),or AUTO operation , the air
conditioner will start following operation . The fan speed
will be automatically controlled .In the operation
suppression zone where capacity is kept to the minimum ,
overcooling is prevented by raising the temperature
setting by 1
operation. The room temperature is thus regulated
between the operation suppression zone and the set
temperature.(It depends on the outdoor temperature.)
Cooling
Fan only
DRYING OPERATION
The dry mode will automatically select the drying
operation based on the difference between the set
Time
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 speed indicator will display AUTO and
low speed will be used.
