Operating tips

Anti-cold air

In HEAT mode, the indoor fan will not operate for up to 5 minutes if the indoor heat exchanger does not reach a minimum temperature for the following reasons:

1. Heating operation has just started.
2. Auto defrosting is just finished.
3. Heating at a low temperature. This is in order to prevent cold air being blown into the room.

Gentle breeze

The indoor unit may blow gentle breeze and the louvre rotates to a certain position in the following situation:

1. In HEAT mode, the unit is turned on, the compressor does not reach the starting condition.
2. In HEAT mode, the temperature reaches the set value and the compressor stops running for about 1 minute.

A white mist is coming out from the indoor unit

• A white mist may generate due to a large temperature differences between air inlet and air outlet in COOL mode in an indoor environment that has a high relative humidity.
• A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT mode operation after defrosting.

Noises coming from the air conditioner

• You may hear a low hissing sound when the compressor is running or has just stopped running. This is the sound of the refrigerant flowing or coming to a stop.
• You also may hear a low “squeak” sound when the compressor is running or just stopped running. This is caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
• A noise may be heard due to louvre restoring to its original position when power is first turned on.

Dust is blown out from the indoor unit

• This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit.

A peculiar smell comes out from the indoor unit

• This is caused by the indoor unit giving off smells permeated from building material, furniture or smoke.

The air conditioner turns to FAN only mode from COOL or HEAT mode

• When the indoor temperature reaches the setting value, the compressor will stop automatically, and the air conditioner turns to FAN mode.

The compressor will start again when the indoor temperature rises in COOL mode or falls in HEAT mode to the set point.

Condensation

• Water droplets are likely to form at the air outlet if cooling or drying for a long time when the relative humidity is more than 80% (with doors and windows open).

Set the vertical louvre to its maximum angle (to the floor) and High fan speed. Close the doors and windows.

Other interferences

Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit with power and then re-connect the unit with power again. Push ON/OFF button on the remote control to restart operation.

X-Fan function

The indoor unit may keep running after you switch off the unit by pressing ON/OFF button. Please check whether the X-Fan function is switched off.
