TROUBLESHOOTING

The following symptoms do not indicate malfunction.

SYMPTOM	CAUSE
Mist emerges from indoor unit. ▶ • Condensation effect due to cooling process.
Water flowing sound during operation.	• Refrigerant flow inside the unit.
The room has a peculiar odour. ▶ • This may be due to damp smell emitted by the wall, carpet, furniture or clothing.
Indoor fan stops occasionally during automatic fan speed setting.	• This helps to remove the surrounding odours.
Operation is delayed a few minutes after restart.	• The delay is a protection to the unit's compressor.
Outdoor unit emits water/steam. ▶ • Condensation or evaporation occurs on pipes.
Timer indicator is always on. ▶ • The timer setting repeats daily once set.
Power indicator blinks during operation and the indoor fan is stopped.	• The unit is in defrost mode, and the melted frost is drained from the outdoor unit.
Indoor fan stops occasionally during heating operation.	• To avoid unintended cooling effect.
Power indicator blinks before the unit is switched on.	• This is a preliminary step in preparation for the operation when the ON timer has been set.
Cracking sound during operation. ▶ • Changes of temperature cause the expansion/contraction of the unit.

Check the following before calling for servicing.

SYMPTOM	CHECK
Heating/Cooling operation is not working efficiently.	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.
