INSTALLATION INSTRUCTIONS
A. Choosing Proper Location For Unit
This unit 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 locations-The unit is designed to fit over
an existing roof vent opening.
2. Other locations-When no roof vent is available
or another location is desired, the following is
recommended:
a. For one unit installation: The unit should be
mounted slightly forward of center (front to
back) and centered from side to side.
b. For two unit installations: Install one unit 1/3
and one unit 2/3’s from front of RV and cen-
tered from side to side.
It is preferred that the unit be installed on a relatively flat
and level roof section measured with the RV parked on a
level surface. See table below for maximum acceptable tilt.

d.
Maintain structural integrity.
Otherwise damage to product and/or RV
could occur.
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.
e. Check inside the RV for air distribution box
(hereinafter referred to as "ADB") obstruc-
tions (i.e. door openings, room dividers, cur-
tains, ceiling fixtures, etc.). See
(FIG. 3).
