OPERATION

THERMOSTAT

Heaters include a bimetal thermostat for the automatic control of the exiting air temperature. The thermostat knob controls the heating elements and fan functions. The heater and fan are de- energized with the knob in the extreme clockwise position.

Turning the knob clockwise from the off position to the fan position will energize the fan only, for use in summer cooling.

The adjustment knob controls power to the heater and fan when turned further in the clockwise direction, with the highest tempera- ture setting in the extreme clockwise position.

The temperature setting in the heater mode is approximately 40°F in the low setting and 100°F at the highest setting.

Note: The adjustment knob should be turned to the fan only set- ting after use for heating. The fan should be left on for at least 3 minutes to remove residual heat from the unit and to prevent over- heating of the housing.
