OPERATION

C.1

General

1. To operate heater, ensure power supply is properly
connected as specified in the wiring schematic (refer to
Figures 3A – 3F, page 5 – 7).
2. If unit is equipped with an optional thermostat, ensure the
thermostat is set above the ambient temperature.
3. If unit is equipped with the optional "FAN ONLY" switch,
ensure the switch is in the "ON" position. Note: If the switch
is in the "FAN ONLY" position, only the fan will energize, not
the heating elements.
D. REPAIR & REPLACEMENT
WARNING. Disconnect heater from power supply at
disconnect or fuse box before opening enclosures or
servicing heater.
WARNING
Lock the switch in the "OFF" (open) position and tag
the switch to prevent unexpected power application.
This heater should only be serviced by qualified
personnel with electrical heating equipment experience.
Install and use the heater in accordance with local
codes and this manual.
NOTE: ONLY USE FACTORY SUPPLIED REPLACEMENT PARTS OF
THE SAME SPECIFICATION. REFER TO TABLE 3, PAGE 10 FOR
COMPLETE LISTING OF AVAILABLE PARTS.
D.1

1. Disconnect all wires connected to the heating element
terminals. Remove louver assembly from heater. Remove
heating elements, noting their proper placement.
2. Install factory-supplied replacement heating element (see
Table 3, page 10 for Parts List).
2.1 Ensure heating element attaching screws are in good
condition.
2.2 Re-attach heating element mounting screws and
tighten.
2.3 Check heating elements are not in contact with the

4. During normal operation, the thermal cut-out control should not
cycle the heater ON and OFF. If cycling occurs, check to see
if there is an airflow blockage. If there are no obstructions, the
heater must be examined by qualified personnel to determine
the cause of the thermal cut-out cycling.
5. Operate the unit for a minimum of 10 minutes to allow the
heating elements to reach a steady state. If no warm air
is discharged from the heater, shut off the unit and see
Section F. Troubleshooting Tips, page 11.
D.2 Fan
1. Remove the rear grille. Remove the screw securing the fan
to the fan hub attached to the motor.
2. Replace fan with factory-supplied fan. Install the fan such
that the "spider" of the fan faces the inside of the heater, i.e.
facing towards the elements.
D.3

Thermal Cut-Out

1. Disconnect all wires connected to thermal cut-out.
2. Remove two mounting screws.
3. Remove thermal cut-out switch from the enclosure.
4. Replace thermal cut-out with factory-supplied replacement
thermal cut-out.
5. Reinstall thermal cut-out switch in the control enclosure.
