Please read carefully the Owner’s manual before usage and keep it handy to ensure the safe, normal and
satisfactory operation of the air conditioner.
With the most advanced and internationally famous branch rotary compressor and the patented technologies
of the company, the temperature rise of the compressor in use can be slowed down, and thus its working life
will be greatly extended.
A new powder coating technology for metallic materials has been adopted for all easily corrode parts, so that
the anti-corrosiveness of the unit is 100 - 200% higher than that of normally galvanization.
The blower wheel and blades are precision moulded with the adoption of high rigidity engineering plastics, so
that only the serviceability of the blower wheel and blades is enhanced. Also the blades’s section is
aerodynamically shaped, thus reducing the air noise dramatically.
In addition, the unit provides large cooling capacity, low noise, nice aesthetic look, innovational structure etc...
The unit particularly suited for home, office, hotel etc...

High Cool
Turn the function selector switch to “Hi Cool” then the unit automatically conducts
the high cool operation, rapidly reducing the room temperature while
dehumidifying and filtering the air and the dust in the room at the same time.
Low Cool
Turn the function selector switch to “Low Cool” and the unit automatically
conducts mild cooling operation while dehumidifying the room and
eliminating the dust
Temperature Adjustment
After turning on the unit, adjust the temperature controller when the room
temperature reduces to the desired level. Slowly turn the thermostat selecting
switch from the coolest point “10”. The compressor will stop operating when a
“click” sound is heard, indicating that further cooling will cease. The
temperature controller automatically turns on the unit for cooling after the room
temperature has gradually increased, and the temperature controller turns off
the cooling operation when the room temperature reduces to your desired
choice.
Note:
O
Adjust the temperature controller until you feel comfortable (normally 26 - 30 C).
Remember that after the temperature selector is adjusted, clockwise adjustment of
the temperature selector is not possible within 3 minutes interval, preventing the
compressor from being burnt out.

strong electrostatic filter, it could be reused after cleaning and
drying.
Please refer to the following suggestions, in order to improve the cooling efficiency, reduce noise and
save electricity costs.
