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.

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: A 8° slant toeither side, or front to back, is acceptable for all units.

3.After Location Has Been Selected:

a.Check for obstructions in the area where air conditioner will be installed. See FIG. 3 & 4.

b.The roof must be designed to support 130 poundswhen the RV is in motion. Normally a 200 lb. static load design will meet this require- ment.

CAUTION

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.

c.Check inside the RV for return air kit obstruc- tions (i.e. door openings, room dividers, cur- tains, ceiling fixtures, etc.) See FIG. 3 & 4.
