Set to either “ 

 ” LOW COOL or “ 

 ” HIGH

COOL and “ 

 ” LOW HEAT or “ 

 ” HIGH

HEAT as required.
(FAN setting operates the fan only.)

* Caution: If the Main Control Knob is turned

off or changed to a fan setting from a cooling
or heating operation setting, WAIT at least 3
minutes before resetting to a cooling or
heating operation.

Set the Thermostat Control Knob to the desired
setting. (Usually “  ~ ” (Red) is a
recommended setting for heating and “  ~  ”
(Blue) for cooling.) If the room temperature is
unsatisfactory after a reasonable amount of
time, turn the control knob clockwise or anti-
clockwise to make the room cooler or warmer.

• When the Thermostat Control Knob is set to

“

” (Blue), moisture may freeze onto the coils

and prevent effective cooling. If this happens,
turn the knob to “     ” (Gray) FAN, and the
thermostat control knob anticlockwise. This will
quickly defrost the cooling coil so that normal
cooling can be resumed.

the Air Swing Switch to “      

” ON and leave it

there.
