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.

Maintenance
For Smart Use of The Air Conditioner
WARNING
Before maintenance, be sure to turn off the system and the circuit breaker.
Remote Controller
Do not use water, wipe the controller with a
dry cloth. Do not use glass cleaner or chemical
cloth.
Indoor Body
Wipe the air conditioner by using a soft and
dry cloth. For serious stains, use a neutral
detergent diluted with water. Wring the water
out of the cloth before wiping, then wipe off
the detergent completely.
Do not use the following for cleaning
Gasoline,benzine,thinner or cleanser may
damage the coating of the unit.
Hot water over 40oC(104oF) may cause
discoloring or deformation.
Air Filter Cleaning
Open the inlet grille by pulling it upward.
Remove the filter.
Push up the filter's center tab slightly until it is released
from the stopper, and remove the filter downward.
Clean the filter.
Use a vacuum cleaner to remove dust, or wash the filter with
water. After washing, dry the filter completely in the shade.
Attach the filter.
Attach the filter correctly so that the "FRONT" indication is
facing to the front.Make sure that the filter is completely
fixed behind the stopper.If the right and left filters are not
attached correctly, that may cause defects.
Air Filter
Once every
two weeks
Close the inlet grille.
Maintenance
To Keep Your Air conditioner in Good Condition
after Season
Operate in cooling mode for 2-3 hours.
To prevent breeding mold or bad smell, be sure to
operate at the designated temperature or 30OC,cooling
mode and High speed fan mode for 2-3 hours.
Put off the power supply cord.
Cleaning the body.
Take out the batteries from the
wireless remote controller.
Maintenance
Before Setting in High Season
Cleaning the standard air filter.
Operation without filter may cause troubles.Be sure
to attach both right and left filters prior to the operation.
Each of them are of different shapes.
Connecting the earthing cable.
Caution
Incomplete earthing may cause an electric shock.
Do not block the air inlet or outlet.
Plug-in
Caution
After brush away dust at the plug, insert the
plug of the power supply cord into the outlet
completely.In case of using exclusive circuit
breaker,switch on the circuit breaker.
EARTHING
NO WET HAND
Trouble shooting
Before asking for service, check the following first.
Cause or check pointsPhenomenon
Normal
Performance
inspection
The system does not restart
immediately.
Noise is heard:
Smells are generated.
Mist or steam are blown out.
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, cigarettes.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Multiple
check
Does not work at all.
Poor cooling
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
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?
