NOTE: For single phase only, a single pole
thermostat may be used if H1 and H2 are
connected with a jumper and P1 and P2 are
connected with a jumper.
How to operate your heater
Turn your built-in or wall thermostat to the desired setting. The
heater will run for approximately 20 seconds before the fan comes
on. The heater will then run until the thermostat setting is reached.
Fan will continue to run with elements shut off for approximately
70 seconds and then will shut off. This cycle will continue as
needed based on thermostat setting. Do not use breaker panel or fuse
box to control heater. Be sure power to heater is constant all the time.

Maintenance
1. Shut off circuit breaker to heater.
2. Remove front diffuser grill or 3 of the center louvers in front of fan area.
3. Using a compressor, blow air through the outer cabinet louvers and
finned element areas. (Do not touch sharp surfaces on elements).
While holding fan blade (to avoid damage or bending) carefully
blow inside the fan motor area.
4. Carefully wipe off the fan blade without damaging or bending it.
5. Reinstall front diffuser or air vanes.
6. Restore power to heater.
Solution
1. Check voltage with voltmeter and/or consult an electrician.
2. Thermostat wires connect at terminal board; supply wires connect at
junction block (see wiring diagram).
3. Remove obstruction. Push manual reset in front.
4. Turn knob past sound of click.
5. Turn circuit breaker on.
6. Replace manual reset.
1. Replace the delay switch.
2. Replace motor and/or check wire connection.
3. Adjust blade as needed.
1. Allow heater to cool, then push reset button.
2. Check with ohmmeter and replace if needed.
3. Check and correct loose wire.
1. Close doors or windows. (See "Operation & Maintenance" section for
instructions).
2. Replace thermostat.
1. Clean heater. (See "Operation & Maintenance" section for instruction).
2. Remove obstruction.
3. Turn off power at circuit breaker. Inspect all supply and heater wire
connections to make sure nothing is loose or poorly connected. Secure
or reconnect all loose connections. Do not reset circuit breaker until all
connections have been checked and repaired.
1. Remove obstruction. Once heater has cooled, push reset button.
2. Remove obstruction.
3. Replace fan motor.
1. Check all clearance requirements.
2. Discontinue use of breaker to control heater, or replace time delay switch.
3. Clean heater. (See "Operation and Maintenance" section for instructions)
4. Location elevation exceeds recommended 7500 feet.
5. Power to heater needs to be constant.
NOTE: For single phase operation, terminal L2
should be left unconnected.
