Installation Instructions

How do I install for
new construction?

Figure 1

Face of wall can must extend

1

/2 inch or 5/8 inch from face of
stud to allow for thickness of
sheetrock.

The CB Series heater REQUIRES A MINIMUM distance
of 6 inches from adjacent surfaces and 4

1

/2 inches from
the floor. However, Cadet RECOMMENDS 12 inches
from all adjacent surfaces and 12 inches above the floor
for longer and cleaner performance. Heaters must be
spaced at least 3 feet apart.

Secure the wall can to the stud with 2 screws (See
Figures 1 & 2). As an option, the rubber shim provided
may be attached to side of wall can to square the wall
can to the stud.

STEP 1

Mount The Wall Can

How do I install in
an existing wall?

Cut a hole 8 inches wide by 101/4 inches high next to a
wall stud. This heater REQUIRES A MINIMUM distance
of 6 inches from adjacent wall surface and 41/2 inches
from the floor. However, Cadet RECOMMENDS 12 inches
from all adjacent wall surfaces and 12 inches from the
floor (See Figure 4).

STEP 1

Cut Hole In Wall

Route the supply wire from circuit breaker to heater.
Remove a knockout and attach the supply wire with a
strain relief connector, leaving 10 inches wire lead for
later use. Connect supply ground wire to grounding
pigtail in wall can (See Figure 3). Proceed to PART
TWO.

READ ALL

INSTRUCTIONS

AND SAFETY

INFORMATION

IMPORTANT!

It is extremely

important you verify

that the electrical

supply wires are the

same voltage as the

heater (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: Install the Com-Pak Bath Heater (Model CB) vertically. Heater is not approved for horizontal or ceiling

mount applications.

CONTROLS: A built-in single pole thermostat and 60 minute timer. (Note: Do not use with a wall thermostat).

Route supply wire from circuit breaker directly to heater.
Remove a knockout and attach the supply wire with a
strain relief connector, leaving 10 inches wire lead for
later use (See Figure 3). Connect supply ground wire to
grounding pigtail supplied in wall can.

STEP 2

Connect Supply Wires

Insert wall can into opening; keeping wall can flush with
wall surface. Secure can to wall stud with 2 screws
through holes provided in can.

Operation & Maintenance

How to operate your heater

1. Once installation is complete and power has been restored, turn

the thermostat knob fully clockwise. (The timer is on the left and
represented by the symbol .

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 counter-clockwise.
To increase the room temperature, turn the knob clockwise.

4. For additional heat beyond thermostat setting, when room is
occupied, turn timer to desired minutes. (The thermostat is on the
right and represented by the symbol ). Heater will remain on until
time expires and then control of the heater will return to the
thermostat and the previous set-point setting.

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. The
first is a high temperature manual reset limit control, 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,
(typically heater is blocked or needs cleaning) use a narrow object
such as a ball-point pen to access the reset button through 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.

Warranty is void if any material is
sprayed on the element or blower.
Use paint mask provided if walls
are to be textured or painted.
