THIS COULD RESULT IN PINCHING
THROUGH THE PLASTIC WIRE
INSULATION AND CAUSE SHORTING
OR “HOT” WIRES TO GROUND
(SHOCK HAZARD). THE CLAMP IS
INTENDED FOR STRAIN RELIEF OF
THE WIRES. SLIGHT PRESSURE IS
USUALLY SUFFICIENT TO
ACCOMPLISH THIS.
IF OTHER THAN NON-METALLIC
CABLES ARE USED FOR SUPPLY
CONDUCTORS, APPROPRIATE
STRAIN RELIEF CONNECTORS OR
CLAMPS SHOULD BE USED.
IN NO CASE SHOULD CLAMPING
OR PINCHING ACTION BE APPLIED
TO THE INDIVIDUAL SUPPLY LEADS
(NEUTRAL AND “HOT” WIRES).
DANGER
SHOCK HAZARD
TO PREVENT THE POSSIBILITY OF
SHOCK INJURY, THE WHITE WIRE
MUST BE CONNECTED TO NEUTRAL
IN THE SERVICE BOX ENTRANCE
AND THE MECHANICAL GROUND
MUST BE CONNECTED TO A
GROUNDING LUG EITHER IN THE
SERVICE BOX OR THE MOTOR
GENERATOR COMPARTMENT.
VII. INSTALLING THE CEILING ASSEMBLY (9000 SERIES)
NOTE
The optional Electric Heating Element is intended to take the
chill out of the indoor air when the air is a few degrees too
cool for comfort The heating element is an effective “chill
chaser”. It is not a substitute for a furnace.
Make sure that you have properly matched the roof top air
conditioner 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. If installing the optional (9470*4551) Electric
Heating Element, position the heater assembly in the
air conditioner return air opening as shown in Figure
5. The heater bracket must be installed over the
metal basepan extrusion and positioned between the
basepan and the plastic drain pan (See Figure 6).
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 air
conditioner with three (3) screws (See Figure 9).
E. Plug the roof top air conditioner electrical conduit
into the 9 position receptacle located in the
thermostat side of the ceiling assembly. If installing
an Electric Heating Element, plug the heater cord
into the 2 position receptacle (See Figure 7).
F. Insert the supply wiring through the cable clamp and
into the field wiring box so that 100-150mm 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 “A” and
“N” lugs on the terminal board. IMPORTANT – If
power is from one “Hot” and one “Neutral”
conductor, connect the neutral to “N”. Connect the
ground wire to the “E” lug on the terminal board (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).
