Trouble Shooting
The following cases are not troubles.
Water flow sound is heard.
"Hua-Hua"
A sound of "Pi-Pa" is generated.
Smells are given off.
During operation, mist or steam are
blown out.
During operation, the air conditioner may
sometimes exhibit a sound of "clatter" or
"rumble". This is the common sound of
refrigerant flow but not a trouble.
This is caused by the thermal expansion
or cold shrinkage of plastics.
Sometimes there are smells in the air flow
from the indoor unit. This is caused by the
smell of cigarettes or paint coatings inside
the unit.
During COOL or DRY operation, the unit
may blow out a thin mist. This is the condensate water mist caused by sudden cooling of the indoor air blown out from the
indoor unit.
