SUPPLYING
POWER TO THE
HEATER BEFORE
DOING ANY
ELECTRICAL
WIRING.
IMPORTANT!
It is extremely important
that you verify that the
electrical supply wires
are the same voltage as
the heater (i.e. 120 volt
heater to 120 volt power
supply and 240 volt
heater to 240 volt power
supply). If replacing an
existing heater, check
the labels of the old
heater and replace
using the same voltage.
Hooking a 240 volt
heater to a 120 volt
power supply will
drastically reduce the
heater's output. Hooking
a 120 volt heater to a 240
volt power supply will
destroy the heater.
Connecting your
heater to an
incompatible power
supply will void
the warranty.
Part One
PLACEMENT: The Com-Pak Plus (Model C) and Com-Pak Twin Plus (Model CT) have been designed, tested

Operation & Maintenance
Wiring Diagrams
How do I insert the heater
assembly into the wall can?
Turn heater assembly upside-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
halfround slots in the bottom lip of the wall can (See
Figure 7). [IMPORTANT: Push wires into bottom of wall
can during insertion. As long as wires are not caught
behind motor, attach assembly at top with screw
provided.]
[IMPORTANT: Be sure that supply wires are not caught
between motor and wall can.] Secure heater assembly
with screw provided.
Install grill
Install grill with the screws provided. If you have a built-in
thermostat model, slide thermostat knob onto shaft. Turn
power on at the circuit panel or fuse box.
STEP 2
STEP 1 Install heater assembly
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. TURN POWER OFF AT CIRCUIT PANEL OR FUSE BOX.
2. Remove grill. Blow down through the element with
compressed air or a vacuum cleaner using the blow cycle.
Vacuum the debris out of the blower wheel. Clean and
reinstall grill.
3. Turn power on at circuit panel or fuse box.
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 reset switch, designed to open the heater
circuit when excessive operating temperatures are
detected.
Further protection is provided by a backup 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
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, 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 GENTLY, 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 page 4 for
more information.

6.Defective thermostat
1. Verify that supply voltage matches the heater rating.
2. The total amperage of all heaters on a branch circuit must not be
more than 80% of the amperage rating of the circuit breaker and
supply wire ratings. Use a lower wattage heater, or reduce the
number of heaters in the circuit.
3. Shorted supply or heater wires may be accompanied by severe
sparking. Inspect all supply and heater wiring insulation for damage.
Do not reset the circuit breaker until any electrical shorts have been
repaired.
4. Replace the circuit breaker.
1. Allow a few moments for element to reach operating temperature.
2. Verify that supply voltage matches the heater rating.
3. Replace heater.
4. CT models have two heating units with independent over-
temperature controls. One of the high-temperature reset switches
may trip and cut power to one of the heating units, while the other
remains running, resulting in only half output. Reset the heater unit
that is not operating (see "Operation & Maintenance" section for
instructions).
1. Close doors and windows. Provide additional insulation, or install a
higher-wattage heater (or multiple heaters if necessary).
2. Adjust themostat to its lowest setting. If heater continues to run
(allow a few moments for the thermostat to respond to the
adjustment), replace thermostat.
3. Refer to thermostat documentation and correct wiring.
1. Clean heater (see "Operation & Maintenance" section for
instructions).
1. Heater requires replacement.
2. Remove obstruction and press heater reset button after allowing the
unit to cool. Test heater operation--if reset button has been pressed
(be sure to listen and feel for a click indicating it has been reset), but
heater does not run, heater requires replacement.
1. Adjust thermostat to a higher temperature until heater operates (see
Problem #6 below if the problem persists).
2. Press the heater reset button (see "Operation & Maintenance"
section for instructions).
3. A severe over-temperature condition has occurred. Replace heater.
4 Turn the correct circuit breaker in the main panel on.
