CP Series Installation Manual

3. Locate T-Bar hanger wires at the corners where the cross
tees intersect the main tees so that they do not interfere with
installation or removal of panels.
4. The heater panels are supplied with four built in
hanging/hold-down clips which are located on each long side
of the heater panel. The clips can be used either to hang the
heater with support wires (see Figure 1) or bent as hold
down clips to the T-Bar frame (see Figure 2). Carefully lift
heater panel into place, making sure hold down clips hook
securely over T-bar (see Figure 2).
Wiring
1. Maximum number of heaters per circuit is limited to circuit
wiring and thermostat or switch capacity.
2. Make wiring connections in accordance with Figure 3 and
wiring instructions. The heater must be properly grounded as
a precaution against electrical shock. Use a properly ground-
ed junction box for connecting the heater to the power supply.
3. Always use a properly grounded junction box when splicing.
See wiring diagrams for proper connections. Install only in a
location where the power supply connections will be accessi-
ble. Install junction box as far above panel as possible and
above building insulation, where present. Use field wiring
suitable for 90 ºC if junction box is allowed to lie on heater or
is enclosed between heater and ceiling above. When
installed in a drop ceiling, the wiring terminals should be
accessible through removable ceiling sections with adequate
clearance to permit access to the top of the heater.
Surface Mounting
1. The Surface Mounting Kit comes in a separate carton which
contains two side frames, two end frames, and eight assem-
bly screws.
2. Assemble the end frames to the side frames using the
screws provided (see Figure 4) before installing on the ceil-
ing.
3. Mount the frame assembly to the ceiling.
4. Remove one end frame and install heater panel in side
frames as shown in Figure 5.
5. Connect the heater panel leads to the power supply leads
(see Figure 3 and WIRING instructions). The heater must be
properly grounded as a precaution against electrical shock.
Use a properly grounded junction box for connecting the
heater to the power supply. The heater may be moved along
side frames to facilitate wiring.
6. Re-assemble the end frame to the side frames to lock the
heater panel securely in place.
TO PREVENT POSSIBLE INJURY FROM ELECTRIC SHOCK,
MAKE SURE THAT ELECTRICITY IS TURNED OFF AT THE
MAIN SWITCH. ALL WIRING MUST BE DONE IN ACCOR-
DANCE WITH NATIONAL AND LOCAL CODES AND THE
UNIT MUST BE PROPERLY GROUNDED AS A PRECAUTION
AGAINST ELECTRICAL SHOCK.
TO PREVENT POSSIBLE INJURY FROM FALLING PANELS,
USE AT LEAST FOUR SCREWS (1/4" OR 0.635 MINIMUM
DIAMETER) TO SECURE EACH SIDE FRAME. SCREWS
MUST THREAD SECURELY INTO A STURDY STRUCTURAL
MEMBER OF THE CEILING, SUCH AS A CEILING JOIST. IT
MAY BE NECESSARY TO FRAME-IN AN EXTRA SUPPORT
MEMBER.
BE SURE ELECTRICITY IS TURNED OFF AT MAIN SWITCH
BEFORE WIRING TO PREVENT POSSIBLE INJURY FROM
ELECTRIC SHOCK.
