CHOOSING LOCATION FOR THE

AIR CONDITIONER

This air conditioner is specifically designed for installation on

the roof of a recreational vehicle (RV).

It is the responsibility of the installer of this

air conditioner/heat pump system to ensure

structural integrity of the RV roof. Never cre-

ate a low spot on the roof where water will

collect. Water standing around the air con-

ditioner/heat pump may leak into the interior

causing damage to the product and the RV.

CAUTION

A. NORMAL LOCATIONS:

The air conditioner is designed to fit over an existing roof

vent opening. When the vent is removed, it normally

creates a 360mm x 360mm opening.

B. OTHER LOCATIONS:

When no roof vent is available or another location is

desired, the following is recommended:

1. 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. 1.

FIG. 2

2/3 L

1/3 L

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, up to 15

slant to

either side, or front-to-back, is acceptable.

C. AFTER LOCATION SELECTION:

1. Check for obstructions in the area where air condi-

tioner will be installed. See FIG. 4.

2. The roof must be designed to support 60 Kg. when

the RV is in motion. Normally a 90 Kg. static load

design will meet this requirement.

c. Check inside the RV for air box obstructions. (i.e.

door openings, room dividers, curtains, ceiling fix-

tures, etc.) See FIG. 3.
