Operation
Remote controller's operation
When in use, put the signal transmission head directly to the
receiver hole on the indoor unit.
The distance between the signal transmission head and the
receiver hole should be within 7m without any obstacle as well.
Don't throw the controller, prevent it from being damaged.
When electronic-started type fluorescent lamp or change-over
type fluorescent lamp or wireless telephone is installed in the
room, the receiver is apt to be disturbed in receivering the signals
so the distance to the indoor unit should be shorter.
Loading of the battery
Load the batteries as illustrated. 2 R-03 batteries, resetting key (cylinder)
Remove the battery cover:
Slightly press " " and push down the cover.
Load the battery:
Be sure that the loading is in line with the" + "/"-"

Application temp. range of air conditioner -7oC~43oC.
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.
Is power plug inserted?
Is there a power failure?
Is fuse blownout?
Is the air filter dirty? Normally it should be
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Is there any direct sunlight through the

Are there too much heat sources or too many
people in the room during cooling operation?
In dry mode, fan

In DRY mode, when room temperature becom-
es lower than temp.setting+2oC,unit will run
intermittently at LOW speed regardless of FAN
setting.
