Problem Cause

Water leakage of

outdoor unit

•Duringcoolingoperation,water

condensates around the pipes and

connection joints.

•Duringdefrostingoperation,thawed

water ﬂows out.

•Duringheatingoperation,wateronthe

heat exchanger drips out.

Noise from indoor

unit.

•Thenoiseemittedwhenthefanor

compressor relay is switched on or off.

•Whenthedefrostingoperation

is started or stopped, there is a

sound of refrigerant ﬂowing in the

reverse direction.

Indoor unit can not

blow air

•InHEATmode,whenthetemperature

of indoor heat exchanger is very low,

air ﬂow is stopped in order to prevent

cold air. (within 2 minutes)

•InHEATmode,whentheoutdoor

temperature is low or humidity is high,

frost will be formed on the outdoor

heat exchanger. The unit will defrost

automatically and indoor unit will stop

blowing air for 3-12 minutes.

•Duringdefrostingoperation,wateror

vapour may be emitted.

•InDRYmode,theindoorfanwillstop

blowing air for 3-12 minutes in order

to avoid condensing water being

vaporised again.

Moisture on air

outlet

•Iftheunitoperatesathighhumidityfora

long time, moisture will be generated on

the air outlet grill and then drip off.

H1: Defrosting

It is normal. The unit is in defrosting mode

and heating will recommence soon.

E3: Low pressure

warning

Your air conditioner has lost refrigerant.

Contact your installer to check for

potential leaks.

The pressure in the refrigeration system is low and could result

in the unit breaking down. Ask a certiﬁed installer to control it.

If any one of the following situations occurs, immediately stop

all operations, disconnect the power supply, and contact the

authorised personnel.

• Thereisaharshsoundduringoperation.

• Strongodoursareemittedduringoperation.

• Waterisleakingfromtheunit.

• Thecircuitbreakeroftentrips.

• Waterorotherliquidissplashedintotheunit.

• Powercordandpowerplugisoverheating.

The air conditioner is not user serviceable. Incorrect repair

may cause electric shock or ﬁre, so please contact an

authorised service center for professional repair.

The following checks prior to contact may save you time

and money.

Problem Cause

The unit does not

operate

The unit does not operate if it is

turned on immediately after it is

turned off. This is to protect the unit.

You should wait about 3 minutes.

Odours are emitted

•Someodoursmaybeemitted

from the indoor unit. This is the

result of room smells (such as

furniture,tobacco,etc.) which have

been taken into the air conditioner.

•Consultauthorisedservicecentrefor

cleaning if the odours persist.

"Water ﬂowing" noise

The swishing noise like water ﬂowing is

the refrigerant ﬂowing inside the unit.

Mist is emitted in

COOL mode

During cooling operation, a thin mist

may be seen emitted from the indoor

unit due to high room temperature

and humidity.

After a period of time, the mist will

disappear as the decrease of room

temperature and humidity decreases.

Cracking noise

This is the sound of friction caused

by expansion and/or contraction of

panel or other parts due to the change

of temperature.

The unit can not be

started up

Remote control does

not transmit signals

•Checkifthereismagneticor

electrical interference near the unit

that may affecting operation of the

remote control. In this case, pull the

plug out and reinsert it.

•Istheremotecontrolwithinits
