4. AIR DISTRIBUTION SYSTEM
INSTALLATION
Dometic Corporation recommends the basic configuration
shown in FIG. 1 for installing this air conditioner/heat pump
system. We have found by testing, that this configuration
works best in most applications of this air conditioner/heat
pump system.
It is the responsibility of the Installer of this system to review
each RV floor plan and determine the following:
A. Duct size
B. Duct layout
C. Register size
D. Register locations
E. Thermostat location.
These items must be determined in conjunction with the Air
Distribution System Sizing and Design Requirements listed
in Section 3 of this manual.
Important:
Alternate configurations and methods
may be used which still allow the air conditioner/heat
pump to operate properly. However, these alternate
configurations and methods must be approved by
Dometic Corporation in writing.
The following instructions are based upon the use of
Dometic Genesis Air Filtration System No. 3308120.XXX.
A.
Before preparing the ceiling opening, the type of system
options must be decided upon. Read all of the instruc-
tions packaged with the system options before
beginning the installation.
B. ROOF AND CEILING OPENING PREPARATION
1. A 14-1/4" x 14-1/4" (±1/8") opening must be cut
through the roof and ceiling of the RV. This opening
must be located between the roof and reinforcing
members.
!
There may be electrical wiring between the
roof and the ceiling. Disconnect 115 volt AC
power cord and the positive (+) 12 volt DC
terminal at the supply battery. Failure to fol-
low this instruction may create a shock haz-
ard causing death or severe personal injury.
2. Mark a 14-1/4" x 14-1/4" (±1/8") square on the roof and
carefully cut the opening.
3. Using the roof opening as a guide, cut the matching
hole in the ceiling.
4. The opening created must be framed and sealed to
provide adequate support and prevent air from being
drawn from the roof cavity. Lumber 3/4" or more in
thicknessmust be used. Remember to provide an
entrance hole for power supplies and system wires as
needed.
