Trouble s hooting  
Followings are not problems  
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.  
Sound of water flowings are  
not problems.  
During unit operation, a cracking noise may be heard.  
This noise is generated by the casing expanding or  
shrinking because of temperatuer changes.  
Sound of cracking is heard.  
Smells are generated.  
This is because the system circulates smells from the  
interior air such as the smell of cigarettes or the  
painting on the unit.  
During operation, white fog or  
steam comes out of indoor 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.  
In cooling operation, unit switches to fan  
operation.  
Unit will not restart after stop.  
Won't start?  
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 3-min-delay  
protection circuit.  
Please wait 3 minutes  
No outlet air or fan speed can't be changed  
in dry mode.  
Unit will reduce fan speed repeatedly and automatically  
if room temp. is too low in dry operation.  
In heating operation, water or steam are  
blown out of indoor unit.  
This occurs when frost accumulated  
on the outdoor unit is removed.  
(during defrosting operation)  
In heating operation, indoor fan won't stop  
even if unit is stopped.  
After unit stops, indoor fan will go on running  
until indoor unit cools down.
