How do I insert the heater
assembly into the wall can?
Turn heater assembly upside-down (element down)
with motor facing you. Connect the supply wires to the
heater wires with connectors (See Figure 6). Now rotate
the heater so the element and fan are facing you (with
the element ‘up’). Insert the bottom edge of the heater
assembly into the half round slots in the bottom lip of
the wall can (See Figure 7). [IMPORTANT: Push wires
into bottom of wall can during insertion. Be sure that
supply wires are not caught between motor and wall
can, attach assembly at top with screw provided.]
How to operate your heater
1. Once installation is complete and power has been
restored, turn the thermostat knob fully clockwise.
2. When the room reaches your comfort level, turn the
thermostat knob counterclockwise until the heater turns off.
The heater will automatically cycle around this preset
temperature.
3. To reduce the room temperature, turn the knob
counterclockwise. To increase the room temperature, turn
the knob clockwise.
Maintenance
As needed, or every six months minimum.
1.) WARNING! Before removing grill, turn the
electrical power off at the electrical panel board (circuit
breaker or fuse box). Lock or tag the panel board door to
prevent someone from accidentally turning the power on
while you are working on the heater. Failure to do so could
result in serious electrical shock, burns, or possible death.
2.) Turn the heater thermostat all the way up and wait
approximately 30 seconds (120 seconds for some electronic
thermostats). If the heater turns on, you have turned off the
wrong circuit breaker at the electrical panel board.
3.) If heater does not turn on, proceed with next step.
4.) Remove screws and take off grill.
5.) Wash grill with hot soapy water and dry immediately.
6.) While holding fan (to avoid damage or bending), use a
hair dryer or vacuum on blow cycle to blow debris through
the top element (Do not touch element).
7.) Vacuum fan area without touching the elements.
8.) Replace grill and secure with screws.
9.) Turn thermostat to desired setting.
10.) Turn power back on at the electrical panel board.
About the Heater Temperature-Limiting Controls
The heater is protected by two temperature-limiting
controls (for Model CT, four controls are used). The first is a
high temperature manual reset switch, designed to open the
heater circuit when excessive operating temperatures are
detected. The problem must be assessed and the limit must
be reset to resume operation.
Further protection is provided by a secondary over-
temperature switch, which will open the heater circuit in
severe over-temperature conditions, or in the event of
component failure. If this occurs, the heater must be
repaired or replaced.
Resetting the Manual-Reset Limit Control
If the manual-reset limit control has opened the heater circuit
due to excessive operating temperatures, the heater will not
work until the limit reset button is pressed. After allowing the
unit to cool for at least 10 minutes and resolving the problem
causing the limit to trip, use a narrow object such as a ball-
point pen to access the reset button through the lower-left
section of the heater grill. Press FIRMLY, and be sure to listen
and feel for a click, indicating it has been reset.
Note that resetting the manual limit control may not restore
heater operation if a severe over-temperature condition has
occurred. See the Troubleshooting Guide on next page for
more information.

G= Ground
T= Thermostat
After you have followed all instructions in PART ONE for either new
construction or an existing wall, you are ready to install the heater assembly.
