physical, sensory or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be
made by children without supervision.
INSTALLATION WARNINGS
•
Ask an authorized dealer to install this air conditioner. Inappropriate installation may cause water
leakage, electric shock, or fire.
•
All repairs, maintenance and relocation of this unit must be performed by an authorized service
technician. Inappropriate repairs can lead to serious injury or product failure.
WARNINGS FOR PRODUCT USE
•
If an abnormal situation arises (like a burning smell), immediately turn off the unit and pull the
power plug. Call your dealer for instructions to avoid electric shock, fire or injury.
•
Do not
insert fingers, rods or other objects into the air inlet or outlet. This may cause injury, since
the fan may be rotating at high speeds.
•
Do not
use flammable sprays such as hair spray, lacquer or paint near the unit. This may cause
fire or combustion.
•
Do not
operate the air conditioner in places near or around combustible gases. Emitted gas may
collect around the unit and cause explosion.

Setting vertical angle of air flow
While the unit is on, use the
SWING/DIRECT
button to set the dir
ection (vertical angle) of
airflow
.
1.
Pr
ess the
SWING/DIRECT
button once to
activate the louver
. Each time you pr
ess
the button, it will adjust the louver by 6°.
Pr
ess the button until the dir
ection you
pr
efer is reached.
2.
T
o make the louver swing up and down
continuously
, pr
ess 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 r
od (See
Fig.B
)
and manually adjust it to your pr
eferred 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 DR
Y 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 dr
op on your floor
or fur
nishings. (See
Fig.A
)
When using COOL or HEAT mode, setting the
louver at too vertical an angle can r
educe the
performance of the unit due to r
estricted air
flow
.
Do not move louver by hand. This will cause the
louver to become out of sync. If this occurs, tur
n
of
f the unit and unplug it for a few seconds,
then restart the unit. This will reset the louver
.

use chemicals or chemically treated
cloths to clean the unit
•
Do not use benzene, paint thinner,
polishing powder or other solvents to clean
the unit. They can cause the plastic surface
to crack or deform.
•
Do not use water hotter than 40°C (104°F)
to clean the front panel. This can cause the
panel to deform or become discolored.
Cleaning Your Air Filter
A clogged air conditioner can reduce the cooling
efficiency of your unit, and can also be bad for
your health. Make sure to clean the filter once
every two weeks.
6.
Rinse the filter with fresh water, then shake
off excess water.
7.
Dry it in a cool, dry place, and refrain from
exposing it to direct sunlight.
8.
When dry, re-clip the air freshening filter to
the larger filter, then slide it back into the
indoor unit.
9.
Close the front panel of the indoor unit.
CAUTION
Do not touch air freshening (Plasma) filter for
at least 10 minutes after turning off the unit.
1. Lift the front panel of the indoor unit.
2. First press the tab on the end of filter to
loosen the buckle, lift it up, then pull it
towards yourself.
3.
Now pull the filter out.
4. If your filter has a small air freshening filter,
unclip it from the larger filter. Clean this air
freshening filter with a hand-held vacuum.
5. Clean the large air filter with warm, soapy
water. Be sure to use a mild detergent.
Remove air freshening ilter from back of

SAFETY PRECAUTIONS
If ANY of the following conditions occurs, turn off your unit immediately!
• The power cord is damaged or abnormally warm
• You smell a burning odor
• The unit emits loud or abnormal sounds
• A power fuse blows or the circuit breaker frequently trips
• Water or other objects fall into or out of the unit
DO NOT ATTEMPT TO FIX THESE YOURSELF! CONTACT AN AUTHORIZED SERVICE PROVIDER
IMMEDIATELY!
Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
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 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
unit turns off the compressor. The unit will continue operating
when the temperature fluctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature difference between the
room’s air and the conditioned air can cause white mist.
Both the indoor
and outdoor units
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.

Issue Possible Causes
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.
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.
The outdoor unit
makes noises
The unit will make different sounds based on its current
operating mode.
Dust is emitted
from either the
indoor or outdoor
unit
The unit may accumulate dust during extended periods of
non-use, which will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods
of inactivity.
The unit emits a
bad odor
The unit may absorb odors from the environment (such as
furniture, cooking, cigarettes, etc.) which will be emitted
during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the
outdoor unit does
not operate
During operation, the fan speed is controlled to optimize
product operation.
Operation
is erratic,
unpredictable,
or unit is
unresponsive
Interference from cell phone towers and remote boosters may
cause the unit to malfunction.
In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation.
NOTE: If problem persists, contact a local dealer or your nearest customer service
center. Provide them with a detailed description of the unit malfunction as
well as your model number.

Troubleshooting
When troubles occur, please check the following points before contacting a repair company.
Problem Possible Causes Solution
Poor Cooling
Performance
Temperature setting may
be higher than ambient
room temperature
Lower the temperature setting
The heat exchanger on the
indoor or outdoor unit is
dirty
Clean the affected heat exchanger
The air filter is dirty
Remove the filter and clean it
according to instructions
The air inlet or outlet of
either unit is blocked
Turn the unit off, remove the
obstruction and turn it back on
Doors and windows are
open
Make sure that all doors and
windows are closed while
operating the unit
Excessive heat is generated
by sunlight
Close windows and curtains
during periods of high heat or
bright sunshine
Too many sources of heat
in the room (people,
computers, electronics,
etc.)
Reduce amount of heat sources
Low refrigerant due to leak
or long-term use
Check for leaks, re-seal if
necessary and top off refrigerant
SILENCE function is
activated(optional function)
SILENCE function can lower
product performance by reducing
operating frequency. Turn off
SILENCE function.
