Operation Tips  
Operation and Performance  
*Heating Performance  
*Microcomputer-controlled Automatic Defrosting  
When using the Heating mode under conditions of  
low outdoor air temperature high humidity, frost  
may form on the outdoor unit, resulting in reduced  
operating performance.  
This air conditioner operates on the heat-pump  
principle, absorbing heat from outdoor air and  
transferring that heat indoors. As a result, the  
operating performance is reduced as outdoor air  
temperature drops. If you feel that insufficient  
heating perfomance is being produced, we  
recommend you use this air conditioner in  
conjunction with another kind of heating  
appliance.  
In order to prevent this kind of reduced  
performance, this unit is equipped with a  
Microcomputer-controlled Automatic Defrosting  
function. If frost forms, the air conditioner will  
temporarily stop, and the defrosting circuit will  
operate briefly (for about 7 to 12 minutes).  
During Automatic Defrosting operation, the  
OPERATION Indicator Lamp will flash.  
Heat-pump air conditioners heat your entire room  
by recirculating air throughout the room, with the  
result that some time may be required after first  
starting the air conditioner until the room is heated.  
*Trouble alarming performance  
During operation, when there is any trouble,  
the operation indicator lamp will flash with different  
times.  
Instructions relating to heating (*) are applicable  
only to "HEAT & COOL TYPE".

Trouble Shooting  
Followings are not problems  
During unit 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 flowing is  
not a problem.  
During unit operation, a cracking noise may be heard.  
This noise is generated by the casing expanding or  
shrinking because of temperature changes.  
Sound of cracking is heard.  
Smell are generated.  
This is because the system circulates smells from the  
interior air such as the smell of cigarettes or the  
painting on the furniture.  
During operation, white fog or steam  
comes out from the indoor unit.  
When unit is running at places like restaurant, etc. where  
dense edible oil fumes always exist, this will happen.  
In cooling operation, unit switches to  
blowing operation.  
To prevent frost from accumulating on indoor heat  
exchanger, unit will switch to blowing operation for a  
while then resume cooling 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 outdoor 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 stop, indoor fan will go on running  
until indoor unit cools down.
