Air conditioner does not start?
When the air conditoner is started, when
the compressor starts or stops during
operation or when the air conditioner is
stopped,it sometimes sounds "Bi- Bi-"or
"Godo-Godo". 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.
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.
Please wait for three minutes.
This is because of the self-protection
function of the system, therefore,it cannot
be restarted for about three minutes after
it stops.
