the lifespan of compressor will be shortened. Please turn off the unit before cutting
the power
Both indoor units can be operated either simultaneously or separately through the
utilization of the advanced converter technique and microcomputer control.
The flowing volume of refrigerant is adjustable through the electronic expansion
valve.
High Cooling and Heating capacity is facilitated through the famous-brand
frequency converter compressor.
Indoor noise is minimized through the optimization of the air flow system design,
a four-folded evaporator and a big diameter Cross Flow Fan.
The system is operable under low-voltage.
Effective and prompt defrosting correlates into no cold feelings.
High heating effects under extremely low temperatures.
The systems purging function improves the quality of the air in the room.
Wireless remote controlled function:
---A Manual Switch can operate the air conditioner when the remote controller is
misplaced and the batteries are exhausted.
---Horizontal and vertical louvers can swing automatically and the customized.

The starting angle of the horizontal louver should not be too small, or the narrow air
outlet will affect cooling or heating.
Do not move the vertical louver manually ,or it may malfunction during operation,
If the malfunction happens, please stop operating unpluge for several minutes then
plug again and restart.
Do not operate the air conditioner for long with the airflow direction set downward during
the cooling or drying operation. Otherwise, condensation may occur on the surface of
the vertical louver and cause dew dripping.
When the air conditioner restarts the vertical louver might not move for 10seconds or so.
At the first time to operate, there may be some noise when horizontal louver is turning, it
is under control.
Switch may have blown.

Any other unusual condition is observed
When air conditioner is in "Cooling" ,"Dehumidifying" or "Heating"operating,
there may be some "ss"sound caused by the flowing between indoor and outdoor unit of
refrigerant.
After air conditioner starting or stopping for a short while there may be some "zz" sound
caused by natural expansion or shrinkage of plastic parts because of the temperature
change.
At the first time to connect the power supply ,there may be some noise caused by the
louvers turning to its original position.
"Automatic”,
Protection for compressor---you can't start compressor within 3minute.
Warm air control (cooling and heating type)
Under the HEAT mode, the indoor fan speed is automatically reduced or stopped
to prevent a cold draft if the set temperature of the indoor heat exchanger has not
been reached under the following three situations:
Frost may be generated on Outdoor Heat Exchanger when outdoor temperature is low
and humidity is high, It would lower heating efficiency of the conditioner, The air
conditioner would stop heating operation and start defrosting automatically, After
finishing the defrosting, it will restart heating operation.

While simultaneously operating both indoor units, the secondary unit can not be operated in
a mode conflicting to that of the primary unit. The unit initially started should be considered
as the primary unit. In the circumstance that the operable modes are conflicting with each
other, the TIMER lamp and DEF lamp located on the display panel of the secondary unit will
flash at a rate of 5 times per second. This can be rectified through changing the operable
mode of the conflicting unit.
