7.2. How to Operate.

Fig. 1
(1) Open the Control Panel Cover.
Fig. 2
(2) Power Supply

OFF position before plugging the power plug into an
electrical outlet.
Fig. 3
(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.)
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
cooling operation.
Fig.4
(4) Thermostat Control Knob.
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.
