Troubleshooting

The followings are not malfuncition

Water flowing sound is heard

Hua

Hua

When the air conditoner is started, when the compressor starts or stops during operation or when the air conditioner is stopped,it sometimes sounds ì Bi- Bi-î or ìGodo-Godoî. It is the flowing sound of the refrigerant , not a malfunction.

Cracking sound is heard

It smells.

During operation, white fog comes out of indoor unit.

This is caused by heat expansion or contraction of plastics

Air blown out from the indoor unit sometimes smells. The smell results from smells of furniture, paint , tobacco absorbed by indoor unit.

When in COOL or DRY mode, a thin water fog can be seen blown out of unit ,this is the condensed fog because the suddenly cooled indoor air is blown out.

Automatically switch into FAN mode during cooling.

To prevent frost from being accumulated on the indoor unit heat exchanger, it sometimes automatically switched into the FAN mode,but it will soon back to the cooling mode.

The air conditioner cannot be restarted soon after it stops.

Air conditioner does not start?

This is because of the self-protection function of the system, therefore,it cannot be restarted for about three minutes after it stops.

Please wait for three minutes

19

Troubleshooting
