Troubleshooting
The followings are not malfuncition
Hua
Hua
Water flowing sound is heard When the air conditoner is started, when the
compressor starts or stops during operation
or when the air conditioner is stopped,it som-
etimes 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.
This is caused by heat expansion or contra-
ction of plastics
Air blown out from the indoor unit sometimes
smells. The smell results from smells of
furniture, paint , tobacco absorbed by indoor
unit.
During operation, white fog comes out of
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 auto-
matically 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
