Trouble shooting
Followings are not problems
Sound of water flowings are not
problems.
Sound of cracking is heard.
Smells are generated.
During operation, white fog or steam
comes out of indoor unit.
In cooling operation, unit switches to fan
operation.
Unit will not restart after stop.
Won't start?
During unit start and operation or at stop, a swishing or
gurgling noise may be heard. 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 temperatuer changes.
This is because the system circulates smells from the
interior air such as the smell of cigarettes or the painting
on the unit.
When unit is running at places like restaurant where dense
edible oil fumeis always exist, this will happen.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to fan operation for a while
then resume cooling operation.
Though ON/OFF button is set to
ON, unit won't resume cooling,dry
or heating operation in 3 min after
it is stopped, this is because of 3min-delay protection circuit.
No outlet air or fan speed can't be changed in
dry mode.
In heating operation, water or
steam are blown out of indoor
unit.
In heating operation, indoor fan won't stop even
if unit is stopped.
Please wait 3 minutes
Unit will reduce fan speed repeatedly and automatically
if room temp. is too low in dry operation.
