INSTALLATION INSTRUCTIONS
A. Choosing Proper Location For Unit
This unit is specically 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. For one unit installation: The unit should be
mounted slightly forward of center (front to back)
and centered from side to side.
2. For two unit installations: Install one unit 1/3 and
one unit 2/3’s from front of RV and centered from
side to side.
It is preferred that the unit be installed on a relatively at
and level roof section measured with the RV parked on a
level surface. See table below for maximum acceptable tilt.
