BEFORE CALLING FOR SERVICE

The following conditions do not denote equip- ment malfunctions

UNIT DOES NOT OPERATE

The unit will not operate if it is turned on immediately after it is turned off. The unit will not operate immediately after the mode is changed. This is to protect the unit. Wait 3 minutes before operating the unit.

UNIT DOES NOT SEND OUT WARM AIR

The unit is preheating or de-icing.

ODORS

Carpet and furniture odors that entered into the unit may be recirculated by the unit.

CRACKING NOISE

This sound is generated by the friction of the unit expanding or connecting due to a temperature change.

A LOW BUZZING NOISE

This is a sound of the unit generating Plasmacluster ions.

SWISHING NOISE

The soft, swishing noise is the sound of the refrigerant flowing inside the unit.

MIST SEEN AT INDOOR AIR OUTLET

In cooling operation, this is caused by the difference between the room air temperature and the air discharged.

WATER VAPOUR

In heating operation, water vapour may flow out of the outdoor unit during de-icing.

THE OUTDOOR UNIT DOES NOT STOP

After stopping the operation, the outdoor unit will rotate its fan for about a minute to cool down the unit.

ODOR EMITTED FROM THE PLASMACLUSTER AIR OUTLET

This is the smell of ozone generated from the Plasmacluster Ion generator. The ozone concentration is very small, posing no adverse effect on your health. The ozone discharged into the air rapidly decomposes, and its density in the room will not increase.

Check the following points before calling for service.

IF THE UNIT FAILS TO OPERATE

Check if the circuit breaker has tripped or the fuse has blown.

IF THE UNIT FAILS TO HEAT (OR COOL) THE ROOM EFFECTIVELY

Check the filters. If dirty, clean them.

Check the outdoor unit to make sure nothing is blocking the air inlet or outlet.

Check the thermostat is properly set.

IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL

Check whether the remote control batteries have become old and weak.

Try to send the signal again with the remote control pointed properly towards the unit’s signal receiver window.
