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.
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.
The air conditioner cannot be restarted soon
after it stops.
Air conditioner does not start?
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.
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

Trouble Shooting
Air does not blow or the fan speed cannot be
changed during drying.
Water or vapor generated from the outdoor
unit during heating.
During heating,indoor fan is still running even
unit is stopped.
In DRY mode, when room temperature
becomes 2 C higher than temperature setting,
unit rill run intermittently at LO speed regardless
of FAN setting
This happens when the frost accumulated on
the outdoor unit is removed (during defrosting
operation).
Defrosting operation
To get ride of the excess heat, indoor fan will
continue running for a while after unit automatically stops.
