Press CLOCK button, "AM" or "PM" flashes.
Press or to set correct time. Each press will increase or decrease 1min. If the
button is kept depressed, time will change quickly.

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.

Left and right air flow adjustment
(manual)
Move the horizontal blade by a knob on air
conditioner to adjust left and right direction
referring to Fig.
Cautions:
When humidity is high, condensate water
might occur at air outlet if all horizontal
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.

(Necessary installment)
Close the Inlet grille
Close the grille surely.
NOTE:
The photocatalyst air purifying filter and the bacteria-killing medium air purifying filter
will be used based on real situation.
The photocatalyst air purifying filter will be solarized in fixed time. In normal family,
it will be solarized every 6 months. The solarization time will last no less than 8 hours
under the state of abundant sun.
The bacteria-killing medium air purifying filter is available for a long time and neednít
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)

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?
