ADJUSTING AIRFLOW DIRECTION
Adjust the airflow direction prop-
erly; otherwise, it might cause
discomfort or cause uneven room
temperatures.
Adjust the horizontal louver using
the remote control.
Adjust the vertical louver manually.
Adjusting Vertical Airflow Direction (up-
down)
The air conditioner automatically
adjusts the vertical airflow direction in
accordance with the operating mode.
Setting Vertical Airflow Direction
Perform this function while the unit
is in operation. Keep pressing the
AIR DIRECTION button on the remote
control to move the louver to the desired
direction.
Adjust the vertical airflow direction
to the desired direction.
In subsequent operations, press the
AIR DIRECTION button to automati-
cally set the vertical airflow.
Setting Horizontal Airflow Direction (left-
right)
Adjust the vertical louver manually
using the lever on the left or right side
of the vertical louver arm (depending on
model). Take care not to catch fingers on
the fan, horizontal louver, or to damage
vertical louvers. When the air conditioner
is in operation and the horizontal louver
is in a specific position, move the lever
at left (or right, depending on model)
end of the air outlet to the desired
position.

conditioner is in operation.
Press the SWING button on the remote
control.
To stop the function, press the SWING

! CAUTION
The AIR DIRECTION and SWING buttons will be disabled when the air condi-
tioner is not in operation (including when the TIMER ON is set).
Do not operate the air conditioner for long periods with the airflow 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 horizontal louver manually. Always use the AIR DIRECTION
or SWING button. If you move this louver manually, it may malfunction dur-
ing operation. If the louver malfunctions, stop the air conditioner once and
restart it.
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 airflow 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.

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 depending on what tem-
perature you have selected and the
room temperature.
The air conditioner will control
room temperature automatically
around the temperature point set
by you.
If the AUTO mode is uncomfortable,
you can select desired conditions
manually.
ECONOMIC (SLEEP) OPERATION
When you push the ECONO (SLEEP)
button on the remote control
during cooling, heating, or AUTO
operation, the air conditioner will
automatically increase (cooling) or
decrease (heating) one (1) per hour.
The set temperature will be steady
two (2) hours later. The fan speed
will be automatically controlled.
This feature can maintain the most
comfortable temperature and save
more energy for you.
•
•
•
•
DRYING OPERATION
The dry mode will automatically select the DRY operation based on the dif-
ference between the set temperature and the actual room temperature.
The temperature is regulated while dehumidifying by repeatedly turning on
and off the cooling operation or fan only. The fan speed indicator will display
AUTO and low speed will be used.
