• If the room temperature is not as desired after
areasonble period, turn the thermostat control knob
clockwise to make the room cooler or counter clockwise
to make the roomwarmer.

• When the thermostat control knob is set to 10, moisture
may freeze onto the evaporator fins and prevent
effective cooling. If this happens, turn the main control
knob to FAN and the thermostat control knob counter
clockwise. This will quickly defrost the evaporator fins so
that normal cooling can be resumed.
NOTE: Usually 4-5 is the recommended setting for heating
and 6-7 is the recommended setting for cooling.
