1.3 CONTROL LOCATIONS

•OPERATION

ELECTRIC HEATING MODEL

TEMPERATURE CONTROL

Set the Thermostat control to the desired temperature mark 5 (the mid-point is a good starting position). If the room temperature is not satisfactory after a reasonable time, adjust the control to a cooler or warmer setting, as appropriate.

•VENTILATION

The ventilation lever is located to the lower left side of the unit. The ventilation lever must be in the CLOSE position in order to maintain the best cooling conditions.

When fresh air is necessary in the room, set the ventilation lever to the OPEN position.

The damper is opened and outdoor air is drawn into the room. This will reduce the cooling or heating efficiency.

CAUTION

When the air conditioner has performed a cooling or heating operation and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation.
