Setting vertical angle of air flow
While the unit is on, use the SWING/DIRECT
button to set the direction (vertical angle) of
airflow.
1. Press the SWING/DIRECT button once to
activate the louver. Each time you press
the button, it will adjust the louver by 6°.
Press the button until the direction you
prefer is reached.
2. To make the louver swing up and down
continuously, press and hold the SWING/
DIRECT button for 3 seconds. Press it
again to stop the automatic function.
The horizontal angle of the airflow must be set
manually. Grip the deflector rod (See Fig.B)
and manually adjust it to your preferred direction.
For some units, the horizontal angle of the airflow
can be set by remote control. please refer to the
Remote Control Manual.
NOTE ON LOUVER ANGLES
When using COOL or DRY mode, do not set
louver at too vertical an angle for long periods
of time. This can cause water to condense on
the louver blade, which will drop on your floor
or furnishings. (See Fig.A)
When using COOL or HEAT mode, setting the
louver at too vertical an angle can reduce the
performance of the unit due to restricted air
flow.
Do not move louver by hand. This will cause the
louver to become out of sync. If this occurs, turn
off the unit and unplug it for a few seconds,
then restart the unit. This will reset the louver.

CAUTION
Do not put your fingers in or near the blower
and suction side of the unit. The high-speed
fan inside the unit may cause injury.
