WARNING: Hazard of Electric Shock. Disconnect all
power before installing heater.
WARNING: Hazard of Electric Shock. Any installation
involving electric heaters must be effectively ground-
ed in accordance with the National Electrical Code to
eliminate shock hazard.
WARNING: Do not store or use gasoline or other flam-
mable vapors and liquids in the vicinity of the heater.
Failure to comply can result in explosion or fire.
An exploded view of the major components of the Cabinet Blower
Heater is shown in Figure 1. The Cabinet Blower Heater is complete-
ly assembled when shipped and must be partially dismantled for instal-
lation.
Removing Front Panel —
To remove front panel, insert Allen wrench in each of two holes at
the upper right and left corners of the panel and turn counterclockwise.
After panel is swung open, pull the two spring-loaded hinges (located
at each end of the panel) towards the center of the panel and remove
panel. Units shipped with doors in position for upflow application. If
unit is to be installed as downflow, both doors can be removed and
installed in reverse position.
Fastening To Wall —
For floor-mounted units it is necessary to use only the holes
marked “A” in Figure 3 in order to secure unit to the wall. The motor
and blower assembly need not be removed. The filter may be removed
to assist in installation.
For wall-mounted units, in order to ensure adequate support, a
greater number of mounting holes may be used. To gain access to
them, the motor and blower assembly and filter must first be
removed. Remove the screws at each end of the assembly as shown
in Figure 2, then pull out assembly. Be sure to disconnect Molex plug
at the blower deck removing assembly. Slide out filter as shown. The
unit is now ready for securing to the wall.
With ceiling mounted units, use the same procedure as in the wall-
mounted units.
Semi and Full-Recessed Applications —
For either semi- or full-recessed applications, care must be taken to
provide the proper size of opening in the wall or ceiling. See Figure 4
for dimensions. On the length and width dimensions, 1/4 inch must be
allowed to insert trim frame.
In a semi-recessed application, the unit can be recessed to any
depth except when the inlet and/or discharge are on the top or bottom
of the cabinet as opposed to the front.
The trim frame is used in recessed applications. See Figure 5 for a
typical application. Refer to Table 1 for proper ordering information.
Accessory Trim Frame Assembly —
Refer to Figure 6 for assembly. Assemble heater frame on a flat
surface. Insert “L” shaped splices into each corner as shown. Use
carpenter’s square to be sure of exact 90˚ angle at corners. Square up
one corner at a time, then center punch one at a time to crimp down
inside flange onto “L” shaped splice. Trim frame can be secured to
wall with screws (not provided), cement or adhesive.
Table 1 Trim Frame —
For recessed mounting in wall or ceiling.
Servicing —
WARNING: Hazard of Severe Shock. Disconnect all
power to heater before servicing.
1. All motors are equipped with lifetime lubrication, consequently no
oiling is required.
2. If motors or blowers need servicing, they can easily be removed by
removing screws as illustrated in Figure 2. Complete assembly
then slides out, after Molex connector is unplugged.
3. If heat sections need servicing, they can easily be removed by
removing screws as illustrated in Figure 7. The complete heat sec-
tion assembly then slides out, after all wires into the terminal block
are removed. Care must be taken to assure that all wires are
replaced in the correct terminal block, per wire numbering or cod-
ing. The limit control and elements can be readily serviced when
the heat section is removed.
4. All controls are readily accessible through the inner control door.
All controls can be serviced through this control door.
5. Filter is accessible after the front panel is opened. Slide filter out
and through the use of a built-in filter track, clean or replace a min-
imum of twice per heating season. Optional permanent type filter
can be cleaned with water and detergent or any available filter
cleaning solution.
Wiring Information —
1. For service entrance refer to Figure 4 for knockout sizes available
and their locations.
IMPORTANT: For upflow application, control section and
knockouts are located on lower right hand side of unit and for
downflow application they will be on upper left hand side of unit.
2. Electric wiring to heater must be installed in accordance with the
National Electrical Code and with local codes by a qualified per-
son. WARNING: Use copper conductors only.
3. Refer to data plate and wiring diagram for correct voltage and
amperage ratings. These must be considered in the sizing of field
wiring.
4. When wiring “-N” and “-R” type heaters, control circuit field
wiring to be suitable for 600 volts.
