2. If surface-mounting frame is used, ensure that the
frame is even with all four heater assembly tabs before
tightening screws.
3. Connect the lead wires from the disconnect switch to
the lead wires from the fan deck. (See wiring diagrams)
After connection, push wires back into opening.

DISCONNECT
4000 & 3000 WATT HEATERS
Full wattage heaters can be converted to half wattage by removing the red
jumper wire connecting the top and bottom element terminals.
1. Turn power to heater on at main switch panel. Rotate the
thermostat knob fully clockwise. This should energize the
heating elements and the fan, causing air to flow from the
air discharge at the openings in the bottom of the grille.
2. After the discharge air has become warm, rotate the
thermostat knob to the desired position to obtain room
comfort.
NOTE: For best results, the heater should be left ON constantly during the heating season since the thermostat, when
properly set, will maintain the desired temperature.
IMPORTANT INFORMATION
TO RESET MANUAL RESET LIMIT
Your heater is equipped with a manual reset safety thermal
limit control that will automatically turn the heater off to prevent a fire if the heater overheats. This control is located on
the fan panel assembly between the element and fan blade
and marked “reset.” The red reset button can be seen
through the front grille when the heater is installed. To reset,
allow the heater to cool, then push the red button that is visible through the hole in the fan panel. The heater should
immediately return to normal operation.
OPERATION OF THE MANUAL RESET SAFETY THERMAL
LIMIT CONTROL IS AN INDICATION THATTHE HEATER HAS
BEEN SUBJECTED TO SOME ABNORMAL CONDITION. IT
IS RECOMMENDED THAT THE HEATER BE CHECKED BY A
REPUTABLE ELECTRICIAN OR REPAIR SERVICE TO
ENSURE THE HEATER HAS NOT BEEN DAMAGED.

heater. THIS IS IMPORTANT.
2. Remove the grille (Fig. 4).
3. With a vacuum cleaner nozzle or dust cloth, remove
dust and other foreign material.
4. After cleaning reinstall the grille.
5. Turn on the main line switch (or replace fuses) to
restore power to the heater. The heater is now ready
for another season of operation.
