•Do not use flammable sprays such as har spray, lacquer or pant
near the unt. Ths may cause fre or combuston.
•Do not operate the ar condtoner n places near or around
combustble gases. Emtted gas may collect around the unt and
cause exploson.
•Do not operate the ar condtoner n a wet room (e.g., bathroom or
laundry room). Ths can cause electrcal shock and cause the product

•Do not expose your body drectly to cool ar for a prolonged perod
of tme.
Electrical warnings
•Only use the specfed power cord. If the power cord s damaged, t
must be replaced by the manufacturer or certfed servce agent.
•Keep power plug clean. Remove any dust or grme that accumulates
on or around the plug. Drty plugs can cause fre or electrc shock.
•Do not pull power cord to unplug unt. Hold the plug frmly and pull
t from the outlet. Pullng drectly on the cord can damage t, whch
can lead to fre or electrc shock.

Poor electrcal connectons, poor nsulaton, and nsuffcent voltage
can cause fre.
Cleaning and maintenance warnings
•Turn off the devce and pull the plug before cleanng. Falure to do

Setting vertical angle of air flow
Whle the unt s on, use the SWING/DIRECT button to set the drecton (vertcal angle) of arflow.
1. Press the SWING/DIRECT button once to actvate the louver. Each tme you press the button, t
wll adjust the louver by 6°. Press the button untl the drecton you prefer s reached.
2. To make the louver swng up and down contnuously, press and hold the SWING/DIRECT button
for 3 seconds. Press t agan to stop the automatc functon.
Setting horizontal angle of air flow
The horzontal angle of the arflow must be set manually. Grp the deflector rod (See Fig.B) and
manually adjust t to your preferred drecton.
For some units, the horzontal angle of the arflow can be set by remote control. please refer to the
Remote Control Manual.
C
Note on louver angles:
When usng COOL or DRY mode, do not set louver at too vertcal an angle for long
perods of tme. Ths can cause water to condense on the louver blade, whch wll drop
on your floor or furnshngs. (See Fig.A)
When usng COOL or HEAT mode, settng the louver at too vertcal an angle can reduce
the performance of the unt due to restrcted ar flow.
Do not move louver by hand. Ths wll cause the louver to become out of sync. If ths
occurs, turn off the unt and unplug t for a few seconds, then restart the unt. Ths wll
reset the louver.

5.1 Common issues
The followng problems are not a malfuncton and n most stuatons wll not requre repars.
Issue Possible causes
Unit does not turn on
when pressing ON/
OFF button
The Unt has a 3-mnute protecton feature that prevents the unt from
overloadng. The unt cannot be restarted wthn three mnutes of beng
turned off.
The unit changes
from COOL/HEAT
mode to FAN mode
The unt may change ts settng to prevent frost from formng on the
unt. Once the temperature ncreases, the unt wll start operatng n the
prevously selected mode agan.
The set temperature has been reached, at whch pont the unt turns off
the compressor. The unt wll contnue operatng when the temperature
fluctuates agan.
The indoor unit emits
white mist In humd regons, a large temperature dfference between the room’s
ar and the condtoned ar can cause whte mst.
Both the indoor and
outdoor units emit
white mist
When the unt restarts n HEAT mode after defrostng, whte mst may
be emtted due to mosture generated from the defrostng process.
The indoor unit
makes noises
A rushng ar sound may occur when the louver resets ts poston.
A squeakng sound may occur after runnng the unt n HEAT mode due
to expanson and contracton of the unt’s plastc parts.
