VIII. INSTALLING THE CEILING ASSEMBLY (9500 SERIES)
Make sure that you have properly matched the roof top heat
pump and interior ceiling assembly. The following step by
step instructions must be performed in the following sequence
to insure proper installation.
A.
Carefully uncarton the ceiling assembly. Controls
are factory installed in the ceiling assembly (except
ceiling assemblies for applications with remote
control box/thermostat).
B.
Remove the grille and filters from the ceiling
assembly.
C.
STEP "C" CAN BE SKIPPED IF THE OPTIONAL
47233(X)4551 HEATER ACCESSORY PACKAGE
IS NOT INSTALLED AT THIS TIME.
Plug the heater cord into the 2 position receptacle
(See Figure 7).
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.
Fold and break off the three tabs around the inner
opening of the duct collar, then fasten the duct collar
to the basepan of the heat pump with three (3) screws
(See Figure 9).
E.
Plug the roof top heat pump electrical conduit into
the 9 position receptacle located in the thermostat
side of the ceiling assembly (See Figure 7).
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 8).
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 8).
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 7).
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 9).
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 7, 8 & 9 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.
L.
Make sure the non-allergenic filters are properly
positioned in the ceiling grille.
M.
Install the ceiling grille by positioning on the bottom
of the shroud and engaging the two 1/4 turn fasteners.
N.
Turn the selector switch to OFF position.
O.
Turn ON the power supply to the roof top heat pump.
