Operation hints  
Unit operation  
Protection devices inside the unit will activate to stop unit operation, when ambient  
temp. is extremely low or high.  
When unit is running under high humidity in cooling or dehumidifying mode, condensate  
might appear at outlet grill.  
3-min delay protection  
Unit will not restart until 3 min have elapsed for the protection of the unit.  
Fan speed changes  
When Fan speed is set at Auto in cooling mode, it will be automatically reduced as  
room temp. is approaching temp. setting.  
In dry mode, fan speed will change automatically.  
Cold draft prevention  
In heating mode, indoor fan will not run for the first 2-5 min. due to cold draft prevention.  
Defrosting  
When frost accumulates on heat exchanger in heating mode, unit will start defrosting  
automatically.  
During defrosting, both indoor and outdoor fan stop.  
After defrosting, unit resumes running.  
Use objectively  
Heat pump works by means of absorbing outside heat to warm room air, so outdoor  
temp. degree will affect unit's heating efficiency.

Trouble shooting  
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 After unit stops, indoor fan will go on running until indoor  
unit cools down.  
if unit is stopped.
