HOW THE AIR CONDITIONER WORKS
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 dependi n g on what tem p er ature
you have selected and the room temperat ur e.
• 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.
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 dec r e as e (he ating) 1 per
hour. The set temperature will be steady 2 hours later. The fan
speed will be automatically controlled .
Note: The unit will be automatically turned off after 7
hours when on SLEEP operation.
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 op er ati o n or fa n
only. The fan speed is LOW.
• The AIR DIRECTION and SWING buttons will be disabled when the air conditioner is not in
operation (including when the TIMER ON is set).
• Do not operate the air c on di tio ne r for l ong pe riods with the air flow direction set downward in
cooling or dry mode. Otherwise, condensation may occur on the surface of the horizontal louver
causing moisture to drop on to the floor or on furnishings.
• Do not move the horizo nt al louv er ma nu all y. Alw a ys u se th e AIR DI RECTION or SWING button.
If you move this louver manually, it may malfunction during operation. If the louver malfunctions,
stop the airconditioner once and restar t i t.
• When the air conditioner is started immediately after it was stopped, the horizontal louver might
not move for approximately 10 seconds.
• Open angle of the horizontal louver should not be set too small, as COOLING or HEATING
performance may be impaired due to too restricted air flow area.
• Do not operate unit with horizontal louver in closed position.
• When the air conditioner is connected to power (initial power), the horizontal louver may
generate a sound for 10 seconds, this is a normal operation.
