Set to either “ 

” LOW COOL or “ 

” HIGH

COOL 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
operation setting, WAIT at least 3 minutes
before resetting to a cooling operation.

Set the Thermostat Control Knob at the
desired setting. (Usually “      ~      ” is a
recommended setting position.) If the room
temperature is unsatisfactory after a
reasonable amount of time, turn the control
knob clockwise to cool the room more, or
anticlockwise to cool the room less.

• When the Thermostat Control Knob is set to
“     ”, moisture may freeze onto the coils and
prevent effective cooling. If this happens, turn
the knob to “ 

 ” HIGH 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.
