3) Installation must comply with the National Elec-

trical Code and any State or Local Codes or

regulations.

4) DO NOT add any devices or accessories to this

air conditioner except those specifically autho-

rized by Dometic.

personnel and some states require these people

B. CHOOSING LOCATION FOR

THE AIR CONDITIONER

This air conditioner is specifically designed for instal-

lation on the roof of a recreational vehicle (RV).

1) NORMAL LOCATIONS:

The air conditioner is designed to fit over an existing

roof vent opening. When the vent is removed, it

normally creates a 14" x 14" opening.

2) OTHER LOCATIONS:

When no roof vent is available or another location is

desired, the following is recommended:

For one unit installation: The air conditioner should

be mounted slightly forward of center (front to back)

and centered from side to side.

For two unit installations: Install one air condition-

ers 1/3 and one air conditioner 2/3's from front of RV

and centered from side to side.

It is preferred that this air conditioner be installed in a

relatively flat and level roof section measured with the RV

parked on a level surface; however,

a. Up to an 8

slant to either side, or front-to-back, is

acceptable on 630 Series Heat Pumps

b. Up to a 15° slant to either side or front-to-back is

acceptable on 591 Series Heat Pumps.

3. AFTER LOCATION SELECTION:

a) Check for obstructions in the area where air

conditioner will be installed.

b) The roof must be designed to support 130 pounds

when the RV is in motion. Normally a 200 lb.

static load design will meet this requirement.

c) Check inside the RV for air box obstructions.

(i.e. door openings, room dividers, curtains, ceil-

ing fixtures, etc.)

C. ROOF PREPARATION

1) ROOF VENT REMOVAL:

a) Unscrew and remove the roof vent.

b) Remove all caulking compound around

opening.

c) Seal all screw holes and seams where the roof

gasket will be located. Use a good grade of all

weather sealer.

2) NEW OPENING:

(Installations Other Then Vent Openings)

DISCONNECT ALL POWER SUPPLIES AND THE POSI-

TIVE (+) TERMINAL FOR THE SUPPLY BATTERY. FAIL-

URE TO FOLLOW THIS INSTRUCTION MAY CREATE A

SHOCK HAZARD.

a) A 14-1/4" x 14-1/4" opening must be cut through

the roof and ceiling of the RV. It is recom-

mended this opening be located between roof

reinforcing members.

b) Mark a 14-1/4" x 14-1/4" square on the roof and

carefully cut the opening.

c) Using the roof opening as a guide, cut the

matching hole in the ceiling.

There may be electrical wiring between the roof and

ceiling.

3) OPENING PREPARATION:

a) If the opening exceeds 14-1/2" x 14-1/2", it will

be necessary to install spacers.

b) If the opening is less than 14-1/4" x 14-1/4", it

must be enlarged.

c) Route a copper 12 AWG, with ground, supply

line from the fuse or circuit breaker box to the

roof opening.

1. The power supply must be on a separate

20 amp Time Delay Fuse or HACR Circuit

Breaker.

2. Wiring must comply with all National, State

and Local wiring codes.

3. Make sure at least 20" of wire extend into

the roof opening. This insures easy air

conditioner attachment.

4. If vent fan was removed, the existing wire

may be used provided it is of proper size

and correctly fused.

d. The opening must be framed to provide ad-

equate support and prevent air from being

drawn from the roof cavity. Lumber 3/4" thick

or more and long enough to bridge the open-

ing must be used. Remember to provide and

entrance hole for the power supply wire.
