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.
Setting horizontal angle of air flow
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.
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.

Issue
Possible causes
Unit does not turn
on when pressing
ON/OFF button
The Unit has a 3-minute protection feature that prevents the
unit from overloading. The unit cannot be restarted within
three minutes of being turned off.
The unit changes
from COOL/HEAT
mode to FAN
mode
The unit may change its setting to prevent frost from forming
on the unit. Once the temperature increases, the unit will start
operating in the previously selected mode again.
The set temperature has been reached, at which point the

emit white mist
When the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process.
The indoor unit
makes noises
A rushing air sound may occur when the louver resets its
position.
A squeaking sound may occur after running the unit in HEAT
mode due to expansion and contraction of the unit’s plastic
parts.

15
Both the indoor
unit and outdoor
unit make noises
Low hissing sound during operation: This is normal and is
caused by refrigerant gas flowing through both indoor and
outdoor units.
Low hissing sound when the system starts, has just stopped
running, or is defrosting: This noise is normal and is caused by
the refrigerant gas stopping or changing direction.
Squeaking sound: Normal expansion and contraction of
plastic and metal parts caused by temperature changes during
operation can cause squeaking noises.
Issue
Possible causes
The outdoor unit
makes noises
The unit will make different sounds based on its current
operating mode.
