Trouble shooting

Cause or check points
●When unit is stopped, it won't restart
immediately until 3 minutes have elapsed
to protect the system.
●When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
●During unit operation or at stop, a
swishing or gurgling noise may be heard.
At first 2-3 minutes after unit start, this
noise is more noticeable. (This noise is
generated by refrigerant flowing in the
system.)
●During unit operation, a cracking noise
may be heard. This noise is generated
by the casing expanding or shrinking
because of temperature changes.
●Should there be a big noise from air flow
in unit operation, air filter may be too dirty.
●This is because the system circulates
smells from the interior air such as the
smell of furniture, paint, cigarettes.
●During COOL or DRY operation, indoor
unit may blow out mist. This is due to the
sudden cooling of indoor air.
