Installing The Ceiling Assembly (8000 Series) - Airxcel RV Products 800 Série Instructions D'installation

VII. INSTALLING THE CEILING ASSEMBLY (8000 SERIES)
The optional Elect-A-Heat is intended to take the chill out of
the indoor air when the air is a few degrees too cool for
comfort. The Elect-A-Heat 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.
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 shroud from the ceiling assembly plate.
C. THIS ENTIRE STEP "C" IS NOT REQUIRED ON
"COOLING ONLY" CEILING ASSEMBLIES. On
ceiling assemblies equipped with the Elect-A-
Heat heater package (heat/cool ceiling assemblies),
detach the bottom heating element support plate by
removing the screws located around the outer edge.
The electrical connection plug will need to be
disconnected before the heat element support plate
can be removed.
D. Before the ceiling assembly can be mounted to the
mount frame, the duct collar must be fastened to the
basepan of the air conditioner with three (3) screws
(See Figure 6).
E. Secure the ceiling assembly plate to the mounting
frame with the screws provided.
F. Pull fabric duct material through ceiling assembly
discharge duct opening. Slit the 4 corners of fabric
duct which extends below duct opening (See
Figure 6).
- FIRE HAZARD -
DO NOT USE FABRIC DUCT TAPE ON OR AROUND
FABRIC DISCHARGE AIR DUCT COLLAR.
ALUMINUM TAPE MAY BE USED IF NEEDED.
NOTE
DANGER
G. Place metal flange in discharge duct opening,
trapping fabric between it and the ceiling assembly
(See Figure 6).
H. Pull fabric tight. This will minimize material
bunching inside the discharge duct collar.
I. Fasten the metal flange to the ceiling assembly with
four (4) screws. To avoid air noise and
restrictions, trim any excess fabric that may
extend beyond edge of metal flange.
J. Route the power supply wire to the back of the
selector switch control box. Do not attach at this
time.
K. Take the roof top air conditioner electrical conduit
and plug it into the back of the thermostat control
box. Make sure that the "ridged" side of the plug is
aligned and matched with the "ridged" side of
thermostat control box connection. DO NOT USE
EXCESSIVE FORCE and make sure the lock-in tabs
are snapped in place (See Figure 7).
L. Remove the selector switch control box cover (one
screw). Take the supply wire and slide it into the
back of the selector switch control box through the
strain relief that is provided.
M. Connect the power line to the black and white pigtail
wires found in the control box using two wire nuts.
IMPORTANT - Connect black wire to black wire
and white wire to white wire. Install the ground
wire (green to bare copper) to the green headed
screw in the selector switch control box. Using a
U.L. approved electricians tape, secure the wire nuts
to the wires in a workmanlike manner (See Figure
8).
N. Tighten the strain relief clamp to secure the supply
wire. DO NOT OVERTIGHTEN (See Figure 9).
Reinstall the selector switch control box cover.
Some ceiling assemblies may be equipped with a
plastic strain relief.
