Electrical Code and any State or Local Codes or
regulations.

air conditioner except those specifically autho-
rized by Dometic.
5. This equipment must be serviced by qualified

B. Choosing Proper Location For The Air
Conditioner
This air conditioner is specifically designed for installation on
the roof of a recreational vehicle (RV). When determining your
cooling requirements, the following should be considered:
•
Size of RV;
•
Window area (increases heat gain);
•
Amount of insulation in walls and roof;
•
Geographical location where the RV will be used;
•
Personal comfort level required.
1. Normal Location-The air conditioner is designed to
fit over an existing roof vent opening.
FIG. 1
2. Other Locations-When no roof vent is available or
another location is desired, the following is recom-
mended:
a. For One Unit Installation: The air conditioner
should be mounted slightly forward of center
(front to back) and centered from side to side.
See FIG. 2.

It is preferred that the air conditioner be installed on a
relatively flat and level roof section measured with the RV
parked on a level surface.
Note: Up to a 15° slant to either side or front-to-back is
acceptable.
3. After Location Has Been Selected:
a. Check for obstructions on the roof and ceiling
where air conditioner will be installed. See FIG.
3.
b. The roof must be designed to support 130
pounds when the RV is in motion. Normally 200
pound static load design will meet this require-
ment.
It is the responsibility of the installer of this
air conditioner system to ensure structural in-
tegrity of the RV roof. Never create a low spot
on the roof where water will collect. Water
standing around the air conditioner may leak
into the interior causing damage to the prod-
uct and the RV.
