Operation Tips
3. Low noise of the air conditioner
You may hear a low hissing sound when the compressor is running or has just stopped running.
This sound is the sound of the refrigerant flowing or coming to a stop.
You can also hear a low "squeak" sound when the compressor is running or has just stopped
running. This is caused by heat expansion and cold contraction of the plastic parts in the unit
when the temperature is changing.
A noise may be heard due to louver restoring to its original position when power is first turned on.
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first
use of the unit.
5. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture,
or smoke.
OPERATING INSTRUCTIONS
Note:
The starting angle of the horizontal louver should not be too small, otherwise the
narrow air outlet will affect cooling or heating efficiency.
Do not set the starting angle of the louvers too small during cooling or drying operation.
Otherwise, condensation may occur on the surface of the horizontal louver and cause
dew dripping.
During the operation, if the louvers can not swing normally, shut offthe unit and unplug
for several minutes, then plug it again and restart the operation.
The horizontal louver may slightly vibrate during the operation. This is normal.
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3 minutes after it stops.
Anti-cold air (Cooling and heating models only)
The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in
one of the following three situations and the set temperature has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low
and humidity is high resulting in lower heating efficiency of the air conditioner.
During this condition air conditioner will stop heating operation and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and
the amount of frost buildup on the outdoor unit.
2. A white mist coming out from the indoor unit
A white mist may generate due to a large temperature difference between air inlet and air outlet
on COOL mode in an indoor environment that has a high relative humidity.
A white mist may generate due to moisture generated from defrosting process when the air
conditioner restarts in HEATmode operation after defrosting.

CARE AND MAINTENANCE
1. Use a dry cloth to wipe the indoor unit and remote controller.
2. Acloth dampened with cold water may be used on the indoor unit if it is very dirty.
3. Do not splash water on unit. This may cause damage to the inner parts or an electric shock.
1. Do not use a chemical-treated duster for wiping or leave such material on the unit for long.
2. Do not use benzine, thinner, polishing powder, or similar solvents for cleaning.
These may cause the plastic surface to crack or deform.
CAUTION: Before performing any maintenance, turn off the main power to the system.
CAUTION:
Cleaning the indoor unit:
Note: Turn the system off before cleaning. Supply power must be disconnected before
cleaning the indoor unit.
Maintenance and Cleaning
6. The air conditioner turns to Fan Mode from COOL or HEAT (For cooling and heating models only)
Mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop
automatically, and the air conditioner turns to Health mode. The compressor will start again when the
indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating models only) to
the set point.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity
(relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and
select HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit
during heating operation. When the outdoor temperature falls, heat drawn in by the air
conditioner decreases accordingly. At the same time, heat loading of the air conditioner
increases due to larger difference between indoor and outdoor temperature. If a
comfortable temperature can't be achieved by the air conditioner, we suggest you use a
supplementary heating device.
9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator
on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the
remote controller. For the unit with Auto-restart feature, when the power restores, the unit
restarts automatically with all the previous settings preserved by the memory function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the
ON/OFF button on the remote controller to restart operation.
11. Vent function
This machine is special designed with Vent function, it is automatically initiated by the fan motor.
The air conditioner have a vent pipe in the indoor unit, when the fan motor is operational, the
indoor polluted air flow out of the room via the vent pipe.

13
1. Clean the indoor unit and air filter.
2. Dry the inner parts by keeping the fan running for half a day.
3. Turn off the unit and switch off the power switch, remove the batteries from the remote control.
4. Periodically check and clean the inner parts of the outdoor unit. Our local dealer will help you
handle this if you contact us.
If the air conditioner operate abnormally, turn off the unit and switch off the power supply, and
contact the local dealer or service centre.
Before restarting, please check if the air inlet and air outlet of the indoor and outdoor units are
blocked up. Clean it so.
Before long time idleness
After long time idleness
Aftersales
CAUTION:
Make sure nothing has been forgotten or fallen into the fan before installing the air inlet grille.
Restart the unit after the air inlet grid is correctly installed and the loop is fastened .
Cleaning the air outlet:
After using for a period, the air outlet and louvers will become dirty. It is recommended to dip a soft
cloth into warm water or a mild kitchen cleanser, ring it out, then wipe any soiling from the unit.
After, wipe with a dry cloth.
Cleaning the Air inlet grille and Air Filter:
If the air filter becomes clogged, the performance will decrease and electricity will be wasted.
The air filter should be checked and cleaned about once every 2 weeks to maintain optimal
performance of the air conditioner.

1. There are three pieces of air filter attached with the air inlet grid, located at both sides and bottom of
the grid(see figure above).
2. Hold both upper sides of the grid and pull it up, let it slant downwards until the rope become straight.
3. Take hold of the side knobs of the air filter and pull it upward.
4. The air inlet grid should be removed first before take out the bottom filter. Use the screwdriver to
loosen the screw fasten the rope, then remove the air inlet grid.
3. The air inlet grid can be wiped with water or a cloth dipped water. Wash it with water and dry it in
a cool place.
4. Use a vacuum cleaner to remove the dust or wash the air filter with water, and dry it in the shadow.
5. Installation process of the air filter and air inlet grid is the reverse of the removal process.
