DANGER – SHOCK HAZARD
MAKE SURE THAT ALL POWER SUPPLY TO
THE UNIT IS DISCONNECTED
PERFORMING ANY WORK ON THE UNIT TO
AVOID THE POSSIBILITY OF SHOCK INJURY
OR DAMAGE TO THE EQUIPMENT.
DANGER! – WHEN USING NON-METALLIC
SHEATH CABLES
SHEATH BACK TO EXPOSE 100-150mm OF THE
SUPPLY LEADS.
STRIP THE INDIVIDUAL WIRE LEAD ENDS FOR
WIRE CONNECTION (ABOUT 19mm BARE
WIRE). INSERT THE SUPPLY WIRES INTO THE
ELECTRICAL CONNECTOR CLAMP. SHEATH
MUST PROTRUDE PAST THE CLAMP BUSHING
INSIDE THE BOX. MAKE SURE SHEATH CABLE
IS CENTERED IN CLAMP BEFORE TIGHTENING
CLAMP ON SHEATH CABLE!!
DO NOT OVERTIGHTEN!! 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
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).

VI. INSTALLING THE OPTIONAL HEATER
ACCESSORY
IMPORTANT NOTE
The optional Heater Accessory is intended to take
the chill out of the indoor air when the air is a few
degrees too cool for comfort. The heater accessory
is an effective "chill chaser". It is not a substitute for
a furnace.
If the 9470B4551 or 45303*4551 heater option is being
installed, 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 between the basepan and the
positioned plastic drain pan (See Figure 6). Tighten set
screw to secure the assembly to prevent movement.
Replace the selector switch control knob on the ceiling
assembly with the knob provided with the optional
heater.
VII. INSTALLING THE 9470*715 CEILING
Make sure that you have properly matched the roof top
unit and interior 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 Air Conditioner
basepan with 3 provided screws (See Figure 8).

C. Raise the ceiling assembly chute and insert the
supply wiring through the cable clamp and into the
wiring box so that 10-15cm of supply conductor is
inside the box. Secure the cable clamp over the
supply wire sheath so that no movement is
possible (See Figure 7).
D. Connect the supply power wires to the supply
power connection strip. Tighten screws to 8 Kg-
centimeters torque.

E. Plug the Air Conditioner electrical conduit into the
9-position receptacle as shown in Figure 7.
F. If the optional heater accessory package is being
installed, remove the cover from the 2-position
receptacle and plug the heater cord into the
receptacle as shown in Figure 7.
G. Raise the ceiling assembly chute to the unit
mounting frame and secure the chute with four
provided screws (See Figure 8).
H. TIE ALL WIRING TO INSURE NO CONTACT IS
POSSIBLE WITH ANY SHARP EDGES OR
OPTIONAL HEATER (IF INSTALLED). KEEP IN
MIND THAT HIGH VELOCITY AIR WILL BE
ENCOUNTERED IN THIS AREA.
I. 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.
J. Raise the ceiling shroud, ensuring it meshes with
the chute, and secure to the mounting frame with
the four provided screws. (See Figure 8).
K. 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.
L. Re-install the filter and grilles into the ceiling
assembly shroud.
M. Turn the selector switch to OFF position.
