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.

(6) Unit stop
Unit won't restart until 3 minutes have
elapsed, due to system protection.
Press ON/OFF button.
Only time remains on LCD.
All indicators on indoor unit go out.
Horizontal flap closes automatically.
Hints
As cold air flows downward in COOL mode, adjusting air flow horizontally will be much more
helpful for a better air circulation.
Be careful not to catch a cold when cold air blows downward.
It is harmful to your health in summer to go frequently in and out of places where temp.
difference is above 7oC. Temp. difference of 3-5oC will remove your fatigue.
More than this, unit's load can be reduced and power consumption cut down as well. So, you'd
better set a temp. difference of 3-5oC between indoor and outdoor temp. in COOL mode.

Trouble shooting
Before asking for service, check the following first.
Phenomenon
Cause or check points
The system does not restart
immediately.
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.)
Noise is heard
Normal
Performance
inspection
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, cigarettes.
Smells are generated.
Mist or steam are blown out.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Does not work at all.
Poor cooling
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
Multiple
check
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
window during the cooling operation?(Use
curtain)
Are there too much heat sources or too many
people in the room during cooling operation?
Application temp. range of air conditioner -7oC~43oC.
