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)

louvers are adjusted to left or right.
Cautions:
Unit won't restart until 3 minutes have
elapsed, due to system protection.
HEAT mode is not available on
cooling only unit.
Hints
As cold air flows downward in COOL mode, adjusting air flow horizontally will be much more
helpful for a better air circulation.
As warm air flows upward in HEAT mode, adjusting air flow downward 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.

Operation
Emergency operation and test operation
Emergency operation:
Use this operation only when the remote controller
is defective or lost.
When the emergency operation switch is
pressed,the" Pi "sound is heard once, which means
the start of this operation.
In this operation, the system automatically selects
the operation modes, cooling or heating, according
to the room temperature.
When machine is running in emergency, the set value of temperature and wind
speed couldn't be altered; meanwhile, it can't operate for dehumidifying or under
timing mode.
Test operation:
Test operation switch is the same as emergency switch.
Use this switch in the test operation when the room
temperature is below 16OC, do not use it in the normal
operation.
Continue to press the test operation switch for more
than 5 seconds. After you hear the "Pi" sound twice,
release your finger from the switch: the cooling operation
starts with the air flow speed "Hi".
Removal of the restriction of emergency or test operation
Press the emergency operation switch once more, or manipulate through the
remote controller; the "Pi" sound, the emergency or test operation is terminated.
When the remote controller is manipulated, it gets the system back to the
normal operation mode.

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.
Do not use the following for cleaning
Gasoline,benzine, thinner or cleanser may
damage the coating of the unit.
Air Filter cleaning
Open the inlet grille by pulling it upward.
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.
Hot water over 40OC(104OC) may cause
discoloring or deformation.
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.
Close the inlet grille.

Maintenance
Replacement of Air Purifying Filter
1.Open the lnlet Grille
Open the inlet grille by pushing each ends of
the inlet grille upward.(use thumbs to push
up)
2.Detach the standard air filter
Slide the knob slightly upward to release the
filter, then withdraw it.
3.Attach new Air Purifying Filter
Put air purifying filter appliances into the
right and left filter frames .
Detach old Air Purifying Filter
4.Install air purifying filter
(Necessary installment)
5.Close the Inlet Grille
Close the Grille surely
NOTE:
The air purifying filter of the bacteria-killing medium and the electrostatic air
purifying filter accessories with machine will be used based on real situation.
The bacteria-killing medium air purifying filter is available for a long time and
needn't to be changed. But it must be noticed to use the vacuum cleaner frequently
to adsorb the dusts covering the purifying filter lest the covering dusts effect the
function of the bacteria-killing medium air purifying filter. (It is strictly prohibited for
the bacteria-killing medium air purifying filter to be washed)
The green aspect of the bacteria-killing medium air purifying filter will face outside,
the white aspect will face to the machine. and the white side of the electrostatic air
purifying filter will face outside.

Trouble shooting
Before asking for service, check the following first.
Normal
Performance
inspection
Phenomenon
The system does not restart
immediately.
Noise is heard
Smells are generated.
Mist or steam are blown out.
Cause or check points
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.
Does not work at all.
Multiple
check
Poor cooling
Application temp. range of air conditioner -7oC~43oC.
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?
