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.

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.
