Installing The Ceiling Assembly - Airxcel 47000 Série Instructions D'installation

Follow all local and NEC (National Electrical Code) for
proper sizing of wire AWG based on Overcurrent
Protection Device selected and the length of the wiring run
to the air conditioner.
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 UP
ON IT. DO NOT OVERTIGHTEN!!
THIS COULD RESULT IN PINCHING
The Electric Heating Element in this ceiling assembly is
intended to take the chill out of the indoor air when the
outdoor temperature is too cold for heat pump compressor
operation. It is not a substitute for a furnace.
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" applies only if optional 47233*4551
Resistance Heat Kit is installed at this time. If
installed, mount the heater bracket on the weld
studs on the channels in the return air opening as
shown in Figure 5. Secure the heater bracket using
wing nuts provided. The heater is then assembled
VII. INSTALLING THE CEILING ASSEMBLY
NOTE
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 MUST
BE USED. IN NO CASE SHOULD
CLAMPING OR PINCHING ACTION
BE APPLIED TO THE INDIVIDUAL
SUPPLY LEADS (NEUTRAL AND "HOT"
WIRES).
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.
to the heater bracket lining up the weld studs on the
heater with the holes on the heater bracket. Secure
the heater in place using wing nuts provided (See
Figure 6).
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 heat pump
with three (3) screws (See Figure 9).
Plug the roof top heat pump electrical conduit into
the 9 position receptacle located in the thermostat
side of the ceiling assembly. Plug the heater cord
into the 2 position receptacle (See Figure 7).
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).
Connect the supply power conductors to the black
and white pigtail wires and the supply ground wire
