ROUTING 115 VAC WIRING
Following Airxcel, Inc. 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
1.
U.L. requires copper conductors only with minimum
#12 AWG.
2.
To prevent voltage drops greater than 10% during
starting loads, adhere to the following guideline:
For lengths greater than 50', use #10 AWG.
Circuit Protection – Refer to upper unit nameplate.
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.
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!!
VII. INSTALLING THE CEILING ASSEMBLY (9000 SERIES)
The optional Electric Heating Element is intended to take the
chill out of the indoor air when the air is a few degrees too
cool for comfort. The heating element is an effective "chill
chaser". It is not a substitute for a furnace.
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.
VI. ELECTRICAL WIRING
DANGER
NOTE
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.
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.
If the ceiling assembly is equipped with an Electric
Heating Element, remove the heater assembly from
the ceiling assembly chute. Position the heater
assembly in the air conditioner return air opening as
