VII. INSTALLING THE CEILING ASSEMBLY
(9400 SERIES)
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. Remove ceiling assembly from carton,
separate individual items and remove the two
grilles and filters from the ceiling shroud.
B. Fasten the duct collar to the roof top unit
basepan with 3 provided screws (See Figure
11).
C. Raise the ceiling assembly chute and insert the
supply wiring through the cable clamp and into
the 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 9).
D. Connect the supply power black conductor to
the black pigtail wire, the white conductor to the
white pigtail wire and the supply ground
conductor to the green pigtail wire found in the
wiring box using the 3 provided wire nuts. Using
a U.L. approved electrical tape, secure the wire
nuts to wires in a workmanlike manner (See
Figure 10).
E. Press supply conductors and wire nuts into
wiring box and making sure no wires are
pinched, secure the wire box cover with 2
provided screws (See Figure 10).
F. Plug the air conditioner electrical conduit into
the 11 position receptacle as shown in Figure
9.
G. If the optional heater accessory is being
installed, remove and discard the cover from
the 2 postion receptacle. Plug the heater cord
into the receptacle as shown in Figure 9.
H. Raise the ceiling assembly chute to the unit
mounting frame and secure the chute with four
provided screws (See Figure 11).
I. TIE ALL WIRING TO ENSURE NO CONTACT
IS POSSIBLE WITH ANY SHARP EDGES.
KEEP IN MIND THAT HIGH VELOCITY AIR
WILL BE ENCOUNTERED IN THIS AREA.
J. Pull the fabric duct material through the ceiling
chute discharge opening. Peel the release liner
from the adhesive strip around the opening.
Press the fabric duct material firmly in place
around the opening. Cut off excess fabric on
inside of ceiling chute with a box knife taking
care not to tear the fabric beyond the adhesive
strip.
K. Raise the ceiling shroud, ensuring it meshes
with the chute, and secure to the mounting
frame with the four provided screws. (See
Figure 11).
L. Install the control knobs over the switch and
thermostat shafts. The thermostat
(temperature) control knob installs nearest the
“Coleman-Mach” logo. If the optional heater
accessory is installed, use the selector switch
knob that was included in the heater package.
M. Re-install the filter and grilles into the ceiling
assembly shroud.
N. Turn the selector switch to OFF position.
O. Turn ON the power supply to the roof top air
conditioner.
