The following symptoms do not indicate malfunction.

Symptom

Cause

POWER indicator blinks before the unit is switched 

on.

• This is the preliminary step to prepare for the TIMER operation 

after it has been set.

• When Timer is set ON, the unit may start earlier (up to 30 

minutes) before the actual set time to achieve the desired 

temperature on time.

TIMER indicator is always ON.

• When Timer has been set, the Timer setting repeats daily.

Operation is delayed a few minutes after restarting.

• The delay is a protection to the unit’s compressor.

Indoor fan stops occasionally during heating 

operation.

• To avoid unintended cooling effect.

Indoor fan stops occasionally during automatic fan 

speed setting.

• This is to help remove the surrounding odour.

Air

fl

 ow continues even after operation has stopped. • Extraction of remaining heat from the indoor unit (maximum 

30 seconds).

The room has a peculiar odour.

• This may be due to damp smell emitted by the wall, carpet, 

furniture or clothing.

Cracking sound during operation.

• Changes in temperature caused the unit to expand and 

contract.

Water 

fl

 owing sound during operation.

• Refrigerant 

fl

 ow inside the unit.

Mist emerges from indoor unit.

• During cooling operation, the discharged cold air may 

condense to water vapour.

Outdoor unit emits water or steam.

• During cooling operation, condensation occurs on cold pipes 

and the condensed water may drip from the outdoor unit.

Discoloration of some plastic parts.

• Discoloration is subjected to the types of materials used in 

plastic parts. It is accelerated when exposed to heat, sun light, 

UV light or environmental factors.

After extended use, dust may cover the front panel, 

grilles and the wall surrounding the unit.

• The dust accumulation is due to the air puri

fi

 cation effect of 

negative ions from nanoe™-G. Remove the dust regularly with 

a clean dampened cloth.

Soft buzzing sound from indoor unit during

nanoe™ TECHNOLOGY operation.

• It is normal when the nanoe™X generator is working. If 

you are concerned about the sound, cancel the nanoe™ 

TECHNOLOGY operation.

Wireless LAN indicator is ON when the unit is OFF.

• The unit’s wireless LAN connection with the router has been 

activated.

Check the following before calling for servicing.

Symptom

Check

Operation in HEAT/COOL mode is not working 

ef

fi

 ciently.

• Set the temperature correctly.
• Close all doors and windows.
• Clean or replace the 

fi

 lters.

•  Clear any obstruction at the air inlet and air outlet vents.

Noisy during operation.

• Check if the unit has been installed at an incline.
• Close the front panel properly.

Remote control does not work.

(Display is dim or transmission signal is weak.)

• Insert the batteries correctly.
• Replace weak batteries.

The unit does not work.

• Check if the circuit breaker is tripped.
• Check if timers have been set.

The unit does not receive the signal from the 

remote control.

• Make sure the receiver is not obstructed.
• Certain 

fl

 uorescent lights may interfere with the signal 

transmitter. Consult an authorised dealer.

The nanoe™ TECHNOLOGY indicator at the indoor 

unit is not ON when nanoe™ TECHNOLOGY is 

activated.

• Use the remote control to retrieve the error code and consult 

an authorised dealer.
