tions.

B. CHOOSING LOCATION FOR
THE AIR CONDITIONER
This air conditioner is specifically designed for instal-
lation on the roof of a recreational vehicle (RV).
1) NORMAL LOCATIONS:
The air conditioner is designed to fit over an
existing roof vent opening. When the vent is
removed, it normally creates a 14" x 14" open
ing.
2) OTHER LOCATIONS:
When no roof vent is available or another
location is desired, the following is recommended:
For one unit installation: The air conditioner
should be mounted slightly forward of center
(front to back) and centered from side to side.
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.
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,
a) Up to a 15° slant to either side or front-to-
back is acceptable on 591 Series Heat
Pumps.
3) AFTER LOCATION SELECTION:
a) Check for obstructions in the area where air
conditioner will be installed.
b) 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 require-
ment.
c) Check inside the RV for air box obstructions.
(i.e. door openings, room dividers, curtains,
ceiling fixtures, etc.)
