Timer indicator is always on.

Power indicator blinks during HEAT mode with no warm air supply (and louver is closed).

Indoor fan stops occasionally during heating operation.

Power indicator blinks before the unit is switched on.

Cracking sound during operation.

►• Condensation effect due to cooling process.

►• Refrigerant ﬂow inside the unit.

►• This may be due to damp smell emitted by the wall, carpet, furniture or clothing.

►• This helps to remove the surrounding odours.

►• Extraction of remaining heat from the indoor unit (maximum 30 seconds).

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

►• Condensation or evaporation occurs on pipes.

►• The timer setting repeats daily once set.

►• The unit is in defrost mode (and AIR SWING is set to AUTO).

►• To avoid unintended cooling effect.

►• This is a preliminary step in preparation for the operation when the ON timer has been set.

►• Changes of temperature cause the expansion/contraction of the unit.

Check the following before calling for servicing.
