Electrical Wiring; Installing The Ceiling Assembly (9000 Series) - Airxcel 48000 Série Instructions D'installation

ROUTING 115 VAC WIRING
Following Airxcel's high voltage wiring specifications and all
local and national electrical codes, route the roof top unit 115
VAC supply wiring from its power source to the wirebox.
High Voltage Wiring Specifications based on Minimum
Overcurrent Protection Device Amperage – (see upper
unit nameplate)
1. U.L. requires copper conductors only with minimum
#12 AWG when using the minimum recommended
overcurrent protection device. Higher rated devices
or longer wiring runs will require #10 AWG or
greater copper conductors.
2. To prevent voltage drops greater than 10% during
starting loads, adhere to the following guideline:
For lengths greater than 50', use #10 AWG or larger
copper conductors. Match to the overcurrent
protection device provided.
Circuit Protection – Refer to upper unit nameplate.
High Voltage Wiring Specifications based on Overcurrent
Protection Device rated higher than the minimum
required (see upper unit nameplate)
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.
VII. INSTALLING THE CEILING ASSEMBLY (9000 SERIES)
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.
VI. ELECTRICAL WIRING
NOTE
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
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).
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.
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.
