2. CHOOSING LOCATION FOR THE
AIR CONDITIONER
This air conditioner is specifically designed for installation
on the roof of a recreational vehicle (RV).
A. For One Unit Installation:
The air conditioner should be mounted slightly forward of
center (front to back) and centered from side to side.
B. For Two Unit Installations:
Install one air conditioner 1/3 and one air conditioner 2/3’s
from front of RV and centered from side to side.
It is preferred that the air conditioner be installed in a
relatively flat and level roof section measured with the RV
parked on a level surface; however,
a. Up to an 8
o
slant to either side, or front-to-back, is
acceptable on 600 and 630 Series units
b. Up to a 15° slant to either side or front-to-back is
acceptable on 591 Series Heat Pumps.
C. AFTER LOCATION HAS BEEN SELECTED:
1. Check for obstructions in the area where air con-
ditioner will be installed.
2. The roof must be designed to support 130 pounds
when the RV is in motion. Normally 200 pound
static load design will meet this requirement.
NOTE
IT IS THE RESPONSIBILITY OF THE INSTALLER OF
THIS AIR CONDITIONER SYSTEM TO INSURE THE
STRUCTURAL INTEGRITY OF THE RV ROOF.
