3. If system includes a gas furnace, route two 18 gauge
thermostat wires from the furnace to the 14-1/4" x
14-1/4" (±1/8") roof opening of the air conditioner
that will control it. Make sure that at least 15" of the
wire extends into the roof opening. If more than one
furnace is to be used, route the second set of
thermostat wire to the second air conditioner.
4. Route a 4-conductor control cable from the Re-
ceiver mounting position into the 14-1/4" x 14-1/4"
(±1/8") roof opening. Make sure that at least 15" of
the wire extends into the roof opening and 6" extend
from the wall at the mounting position of the Re-
ceiver . See Section E-2.
E. Receiver & Cable Installation
Note: The receiver monitors the temperature of the living
area. The following receiver location is recommended to
maintain the selected temperature setting. Any other loca-
tion must be approved by Dometic. See FIG.30.
1.
Locate the receiver in a front to rear position on the
ceiling, and to one side or the other of the return air
cover. See FIG. 8A, 8B & 8C. Mounting the receiver
from side to side is not recommended, but could be
mounted this way as a last possibility.
Note: When used with the 3308120 Genesis Filtration
System, do not mount the receiver where it will interfere with
the filter removal. See FIG. 8A. When used with the 3105935
Quick Cool Return Air Grille do not install near the discharge
air duct. See FIG. 8C.
Note: To operate the air conditioner, the receiver must be
installed in a location that will allow the remote to be in the
line of sight of the receiver.
a. If another receiver mounting location is antici-
pated, observe the following general rules in
determining the location and submit location to
Dometic for approval.
•
Locate the Receiver 54" above the floor.
•
NEVER expose it to direct heat from lamps,
sun or other heat producing items.
•
Avoid locations close to doors that lead
outside, windows or adjoining outside walls
or directly under cabinets or overhangs
which limit air movement.
•
Avoid locations close to supply registers
and the air from them.
•
NEVER locate receiver in a room that is
warmer or cooler than the rest of the RV.
•
The major living area is normally a good
location.
2.
Control Cable Installation
A 4-conductor control cable must be routed from the roof
opening to the Receiver
.
a.
Choose the shortest, most direct route from the
14-1/4" x 14-1/4" (±1/8") opening to the Re-
ceiver
location selected. Leave 6" of cable
extending through the wall. See Section D-4.
b.
The control cable that should be used is a flat,
4-conductor telephone cable.
