C. Remove the heater assembly from the ceiling
assembly chute. Position the heater assembly in
the heat pump return air opening as shown in
Figure 10. The heater bracket must be installed
over the metal basepan extrusion and positioned
between the basepan and the plastic drain pan
(See Figure 11). Tighten set screw to secure the
assembly so as to prevent movement.
TIE ALL WIRING TO INSURE NO CONTACT
WITH THE HEATER OR ANY SHARP EDGES.
KEEP IN MIND THAT HIGH VELOCITY AIR
WILL BE ENCOUNTERED IN THIS AREA.
D. Fasten the duct collar to the basepan of the heat pump
with three (3) screws (See Figure 14).
E. Plug the roof top heat pump electrical conduit into
the 9 position receptacle located in the thermostat
side of the ceiling assembly. Plug the heater cord
into the 2 position receptacle (See Figure 12).
F. Insert the supply wiring through the cable clamp and
into the field wiring box so that 4 – 6" of supply
conductor is inside the box. Secure the cable clamp
over the supply wire sheath so that no movement is
possible (See Figure 13).
G. Connect the supply power conductors to the black
and white pigtail wires and the supply ground wire
to the green pigtail wire found in the field wiring
box using the 3 provided wire nuts. IMPORTANT –
connect the black supply to the black pigtail and the
white supply to the white pigtail. Using a U.L.
approved electrical tape, secure the wire nuts to
wires in a workmanlike manner (See Figure 13).
H. Place the metal control box shield over the
thermostat, switch and field wiring boxes. Make
certain that all wires are pushed into the control
boxes or laying in the wireway between the
thermostat and switch boxes and will not be
pinched by the control box shield. Control box
shield is properly installed when the two holes in
shield are aligned with the two screw holes in the
ceiling assembly chute (See Figure 12).
I. Raise the ceiling assembly and secure to the
mounting frame with 4 provided shoulder
screw/spring assemblies. The front two screws
should pass through the clearance holes in the metal
control box shield (See Figure 14).
J. The ceiling assembly shroud is curved to contour to a
crowned ceiling. If installation is to a flat ceiling
and gaps are present on the sides of the shroud,
insert the four optional 3/4 inch screws (provided)
through the mounting posts and secure them to the
mounting frame above (See Figure 12, 13 & 14 for
screw locations).
K. Pull the fabric duct material through ceiling
assembly discharge opening. Peel the release
liner from the adhesive strip around the
discharge opening. Press the fabric duct material
firmly in place around opening. Cut off excess
fabric on inside of ceiling assembly chute with a
box knife taking care not to tear the fabric
beyond the adhesive strip.
