will automatically change to sleep mode; the main machine will remain current operation
conditions if darkness remains after 8 hrs. Anytime brightness is detected for 10 min,
the unit will quit sleep mode and resume operation conditions before sleep running. Light
sensing and human sensing could be actuated simultaneously, while human sensing
is unavailable during light sensing.
About intelligent operation
During intelligent operation, the indoor human activity or light intensity is sensed
through an intelligent sensor (human sensor, photosensor), and the unit runs as follows

1.At high ambient temperature, the human sensor may detect inaccurately or invalidly
due to thermal airflow.
2.Please notice that itíll enter sleep mode when turning off the room lamps, during which
sleep running continues even if people leave the room.
3.If light sensing and human sensing are both selected, when the photosensor detects
ìdarkî, the air conditioner wonít change its running mode even the human sensor detects
human activity.
4.The human sensor could detect animals such as dogs and cats as well as heat sources
e.g. heaters and electric cookers.

Operation
5.The human sensor could also detect strong electromagnetic waves such as radios and
mob phones.
6.Do not place objects infrared rays couldnít penetrate within the human sensorís perception
range.
Note: If intelligent operation doesnít meet your desire, e.g. slight human activity couldnít
be sensed, it shall be cancelled.
About installing position of air conditioner (indoor unit) and sensible zone of human
sensor:
The dashed area shown in the figure is the sensible zone and the blank area is the dead
zone. (Taking a 12 m2 room as example)

The horizontal zone where human activity could be detected by the human
sensor is about 100o. Sensible zones differ according to installation position and
room space. Please refer to installation examples to select installation position
according to room design.
Vertical direction
As shown in the figure, the sensible zone in vertical direction crosses downward
60o. The sensing distance is 3.5-5 m.

Operation
Emergency 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.

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".
After 30 minutes, test operation ends automatically.
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 ciruit 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 unitl it is released
from the stopper, and remove the fileter downward.
Clean the filter.
Use a vacuun 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
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 desinnated 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.

Trouble shooting
Before asking for service, check the following first.
Normal
Perfromance
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.
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?
