OPERATING INSTRUCTIONS   
THERMOSTAT 
The thermostat is used to set the desired room temperature when the unit is being 
operated in the COOL MODE. 
To set the desired room temperature, rotate the thermostat switch to the desired 
setting. After the set temperature is achieved the thermostat will automatically 
start and stop the compressor in order to maintain the desired set temperature. 
Rotate the thermostat selector clockwise for higher cool settings. Higher cool 
settings will provide lower room temperature. Rotate the thermostat selector 
counter clockwise for lower cool settings. Lower cool settings will provide higher 
room temperature. 
NOTE: 
Test is used to test the compressor and make sure the unit is working properly. 
Do not use this position for regular operation. 
During the cooling operation of the unit, when the thermostat knob is rotated 
clockwise, allow at least three minutes before turning back the knob to the “min” 
direction. 
Otherwise the fuse may blow due to an overload of the unit. 
DO NOT rotate the THERMOSTAT knob beyond the range from “min” to “max”.
