High Cool

Turn the function selector switch to “Hi Cool”  then the  unit automatically conducts 
the high cool operation, so that the room temperature is reduced rapidly and at 
the same time the room is being dehumidified and dust is being filtered.

Low Cool

Turn the function selector switch to “Low Cool” and the unit automatically 
conducts calm cooling operation and  eliminate dust from the room.

Temperature Adjustment

After turning on the unit, adjust the temperature controller when the room 
temperature reduces to the point you desire.  Slowly turn the knob from the 
coolest point “6”.  The compressor will stop operating when a “click” sound is 
heard, indicating that further cooling will stop.  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 that you choose.

Note:

O

Adjust the temperature controller until you feel comfortable (normally 26 - 30 C).

After the temperature controller is adjusted, remember that the temperature control 
knob  can not be adjusted clockwise within 3 minutes, otherwise the compressor 
will be burnt out.
