DANGER – SHOCK HAZARD!
MAKE SURE THAT ALL POWER SUPPLY TO THE UNIT IS
DISCONNECTED BEFORE 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 (ROMEX,
ETC.), STRIP SHEATH BACK TO EXPOSE 4-6 INCHES OF
THE SUPPLY LEADS.
STRIP THE INDIVIDUAL WIRE LEAD ENDS FOR WIRE
CONNECTION (ABOUT 3/4” BARE WIRE). INSERT THE
SUPPLY WIRES INTO THE ELECTRICAL CONNECTOR
CLAMP. SHEATH MUST PROTRUDE PAST THE CLAMP
BUSHING INSIDE THE BOX AS ILLUSTRATED. 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 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.
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.
THE ELECTRIC HEAT ELEMENT IS NOT TO BE INSTALLED
USING THE TOP/DOWN MOUNTING CONFIGURATION.
If the heater option is being installed, position the heater
assembly in the Heat Pump return air opening as shown
in Figure 7. The heater bracket must be installed over
the metal basepan extrusion and positioned between
the basepan and the plastic drain pan (See Figure 9).
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 CEILING ASSEMBLY
(9600 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.
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 Heat Pump 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 Heat Pump electrical conduit into the 9
position receptacle as shown in Figure 9.
G. If the optional heater accessory package is being
installed, remove the cover from the 2 position
receptacle and plug the heater cord into receptacle
as shown in Figure 9.
H. Raise the ceiling assembly chute to the unit mounting
frame and secure the chute with 4 provided screws
(See Figure 11).
I. 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.
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 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 mounting frame with 4 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.
M. Re-install the filters 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 Heat
Pump.
VIII. SYSTEM CHECKOUT
Airxcel, Inc. manufactures a wide range of roof top Heat
Pumps which incorporate different product operation
features. To properly evaluate the performance
of a newly installed Heat Pump, it is necessary to
review the specific unit operation characteristics
(features) described in the product OPERATION AND
MAINTENANCE INSTRUCTIONS section of this booklet.
