(3) Main Control Knob

Set to LOW COOLING or HIGH COOLING and LOW
HEATING or HIGH HEATING as desired. (FAN setting
operates the fan only.)

(4) Thermostat Control Knob.

•

If the room temperature is not as desired after a

reasonable period, turn the thermostat control knob
clockwise to make the room cooler or counter clockwise
to make the room warmer.

•

W hen 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.

desired flow direction is reached, then switch it to “OFF”.

For continuous side-to-side air circulation, set the Air Swing
Switch to “ON”.
