CHOOSING LOCATION FOR THE

AIR CONDITIONER

This air conditioner is specifically designed for installation on
the roof of a recreational vehicle (RV).
CAUTION
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.
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.

2. For two unit installations: Install one air conditioners
1/3 and one air conditioner 2/3's from front of RV and
centered from side to side. See FIG. 2.
FIG. 2
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
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.
