• Clean the unit using a damp, lint-free cloth

and neutral detergent. Dry the unit with a

dry, lint-free cloth.

How To Clean The Air Filter

The ﬁlter prevents dust and other particles from

entering the indoor unit. Dust buildup can reduce

the efﬁciency of the air conditioner. For optimum

efﬁciency, clean the air ﬁlter every two weeks or

more frequently if you live in a dusty area.

Replace the ﬁlter with a new one if it’s heavily

clogged and cannot be cleaned.

WARNING: DO NOT REMOVE OR

CLEAN THE FILTER BY YOURSELF

Removing and cleaning the ﬁlter can be

dangerous. Removal and maintenance must be

performed by a certiﬁed technician.

NOTE: In households with animals, you will

have to periodically wipe down the grille to

prevent animal hair blocking airflow.

Troubleshooting

CAUTIONS

If one of the following conditions occurs, switch off the power supply immediately and contact

your dealer for further assistance.

• The operation light continues to ﬂash 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 the air conditioner.

• Other abnormal situations.

Common Problems

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

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 cannot be restarted within three minutes of being

turned off.

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 off the

compressor. The unit will resume 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.

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 contraction 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 ﬂowing through both the indoor and outdoor units.

A low hissing sound may be heard 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.

The outdoor unit

makes noises The unit will make different sounds based on its current operating mode.
