Display panel

Use the system under the following temperatures for safe and eective operation. If the air condi­tioner is used under dierent conditions, it may malfunction or become less ecient.

Default Setting

When the air conditioner restarts after a pow-

er failure, it will default to the factory settings
(AUTO mode, AUTO fan, 24°C (76°F)). This may

cause inconsistencies on the remote control and
unit panel. Use your remote control to update
the status.

Auto-Restart (some models)

In case of power failure, the system will immedi­ately stop. When power returns, the Operation
light on the indoor unit will ash. To restart the
unit, press the ON/OFF button on the remote

control. If the system has an auto restart func-

tion, the unit will restart using the same settings.

Louver Angle Memory Function (Optional)

Some models are designed with a louver angle
memory function. When the unit restarts after a

power failure, the angle of the horizontal louvers

will automatically return to the previous position.
The angle of the horizontal louver should not be
set too small as condensation may form and drip

into the machine. To reset the louver, press the
manual button, which will reset the horizontal

louver settings.

Refrigerant Leak Detection System
(some models)

In the event of a refrigerant leak, the LCD screen will
display “EC” and the LED indicator light will ash.

• DO NOT set the unit to excessive temperature levels.

• While cooling, close the curtains to avoid direct sunlight.

• Doors and windows should be kept closed to keep cool or warm air in the room.

• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the eciency of the unit.

• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.

• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.

• Clean the air lter every two weeks. A dirty lter can reduce cooling or heating eciency.

• Adjust louvers properly and avoid direct airow.

Safety Precautions

How To Clean The Air Filter

Unit Maintenance

• Contact an authorized service technician for repair
or maintenance. Improper repair and mainte-

nance may cause water leakage, electrical shock,
or re, and may void your warranty.

• DO NOT substitute a blown fuse with a higher

or lower amperage rated fuse, as this may cause
circuit damage or an electrical re.

• Make sure the drain hose is set up according to
the instructions. Failure to do so could cause leak-

age and result in personal property damage, re,

and electric shock.

• Make sure that all wires are connected properly.
Failure to connect wires according to instructions

can result in electrical shock or re.

1. Open the air intake with a screwdriver or similar
tool. Detach the grille from the main unit by hold-

ing the grille at a 45° angle, lifting it up slightly,

and then pulling the grille forward.

2. Take out the air lter, (applicable to 3.2~10.5KW

air conditioners only).

3. Directly pull out the air lter from the air inlet
as indicated (applicable to 14~16KW air condi-

tioners only).

NOTE: In households with animals, you will have

to periodically wipe down the grille to prevent

animal hair blocking airow.

The lter prevents dust and other particles from en-

tering the indoor unit. Dust buildup can reduce the ef-

ciency of the air conditioner. For optimum eciency,
clean the air lter every two weeks or more frequently
if you live in a dusty area. Replace the lter with a new

one if it’s heavily clogged and unable to be cleaned.

BEFORE CLEANING OR
MAINTENANCE

• Always turn o your air conditioning system and

disconnect the power supply before cleaning or
maintenance.

• DO NOT 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 wash the unit under running water. Do-
ing so creates an electrical hazard.

• DO NOT use water hotter than 40°C (104°F) to
clean the front panel. This can cause the panel to
become deformed or discolored.

• Clean the unit using a damp, lint-free cloth and
neutral detergent. Dry the unit with a dry, lint-free

cloth.

WARNING: DO NOT REMOVE
OR CLEAN THE FILTER BY
YOURSHELF

Removing and cleaning the lter can be danger­ous. Removal and maintenance must be per-

formed by a certied technician.

WARNING

• If the refrigerant leaks, turn o the air condi­tioner and any combustible heating devices,

ventilate the room and call your dealer immedi-

ately. Refrigerant is both toxic and ammable.

DO NOT use the air conditioner until the leak is
repaired.

• When the air conditioner is installed in a small

room, measures must be taken to prevent the

refrigerant concentration from exceeding the
safety limit in the event of refrigerant leakage.
Concentrated refrigerant causes a severe health
and safety threat.

4. Remove the air lter.

5. Clean the air lter by vacuuming the surface or

washing it in warm water with mild detergent.

A. If using a vacuum cleaner, the inlet side should

face the vacuum.

Refrigerant Leak Detection System (some
models)

• In the event of a refrigerant leak, the LCD screen

will display “EC” and the LED indicator light will

ash.

• The operation light continues to ash rapidly after the unit has been restarted.

• The remote control buttons do not work.

• The unit continually trips fuses or circuit breakers.

• A foreign object or water enters te air conditioner.

• Other abnormal sitations.

The following symptoms are not a malfunction and in most situations will not require repairs.

Maintenance after Extended Non-Use

1. Remove any obstacles blocking the vents of both
the indoor and outdoor units.

2. Clean the air lter and the front grille of the
indoor unit. Reinstall the clean, dry air lter in its

original position.

3. Turn on the main power switch at least 12 hours
prior to operating the unit.

Storing the Unit While Not In Use

1. Run the appliance on FAN mode for 12 hours in a
warm room to dry it and prevent mold.

2. Turn o the appliance and unplug it.

3. Clean the air lter according to the instructions in
the previous section. Reinstall the clean, dry lter

before storing.

4. Remove the batteries from the remote control.

6. Rinse the lter with clean water and allow it to air­dry. DO NOT let the lter dry in direct sunlight.

Troubleshooting

CAUTIONS

If one of the following conditions occurs, switch o the power supply immediately and contact your

dealer for further assistance.

Problem 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 can-

not be restarted within three minutes of being turned o.

Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/ Defrost) indicators

are lit up, the outdoor temperature is too cold and the unit's anti-cold wind is activated in order

to defrost the unit.

In Cooling-only Models: If the "Fan Only" indicator is lit up, the outdoor temperature is too cold
and the unit's anti-freeze protection is activated in order to defrost the unit.

The unit changes

from COOL mode
to FAN mode

The unit changes its setting to prevent frost from forming on the unit. Once the temperature

increases, the unit will start operating again.

The set temperature has been reached, at which point the unit turns o the compressor. The unit
will resume operating when the temperature uctuates again.

The indoor unit
emitswhite mist

In humid regions, a large temperature dierence 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.

The indoor unit
makes noises

A squeaking sound is heard when the system is OFF or in COOL mode. The noise is also heard
when the drain pump (optional) is in operation.

A squeaking sound may occur after running the unit in HEAT mode due to expansion and con-

traction of the unit's plastic parts.

Both the indoor
unit and outdoor
unit make noises

A low hissing sound may occur during operation. This is normal and is caused by refrigerant gas

owing through both the indoor and outdoor units.

A low hissing sound may be heard when the system starts, has just stopped running or is defrost-

ing. This noise is normal and is caused by the refrigerant gas stopping or changing direction.

The outdoor unit
makes noises

The unit will make dierent sounds based on its current operating mode.

◄ Page 12 ► ◄ Page 13 ►

Problem Possible Causes

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 lters 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.
