Before calling for service

If the unit appears to be malfunctioning, check the following points before calling for service.

Air conditioner does not operate at all

Is the unit plugged in or is the plug loose?

Has the fuse blown or has the circuit breaker tripped?

Did you restart the unit within 3 minutes of a power failure? If the power was off for less than 3 minutes when, you restarted the air conditioner, a protective device may cause the compressor to shut off, preventing cooling for about 5 minutes.

Are the OPERATION and TIMER lamps on the unit blinking?

If so, the water tank inside the unit is full. It must be drained. (See page 19)

Air conditioner does not cool properly

Is the unit set to FAN, DEHUMIDIFICATION or VENTILATION mode? Cooling does not take place in these modes. Change the MODE setting.

Are the filters clogged with dust?

Clean and refit the filters.

• Is the cooling coil frozen?

No air will blow out if the cooling coil is frozen.

Run the air conditioner in FAN mode with the fan speed set to “HIGH” until all ice dissipates.

Is the temperature set properly?

Is the room exposed to direct sunlight?

Close the curtains or blinds to minimize solar energy heating the room.

• Is the exhaust hose too long?

For efficient operation, make the hose as short as possible. The exhaust hose must not be twisted.

Sounds

The unit may seem rather loud for the first 2 to 3 minutes when turned on. This is the sound of the compressor starting-up and is perfectly normal.

A soft, swishing noise can be heard immediately after the unit is turned on or off, and also during operation. This is the sound of the refrigerant flowing inside the unit.

A low buzzing noise is emitted when the unit is generating Plasmacluster ions.

This air conditioner evaporates water condensed during cooling operation within the unit through the exhaust air outlet. Although a water flowing sound may be heard, this is normal.

An audible gurgling sound may be heard for about a minute upon starting MANUAL mode. This is the sound of the drainage pump operating inside the unit.

An audible gurgling sound may be heard when the unit is operated on a gently sloping floor.

Place the unit on a level floor.

Timer does not work properly

If a power failure occurs while the TIMER is set, the TIMER setting will be cancelled and will not be retrieved even after the power is restored. This is normal for this unit.

The unit fails to react to the remote control signal

Check the batteries in the remote control. Replace if necessary.

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

Check whether the remote control batteries are installed with the polarities properly orientated.

The discharged air has an odour

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