3. CHOOSING LOCATION FOR THE
AIR CONDITIONER/HEAT PUMP
This air conditioner is specifically designed for installation on
the roof of a recreational vehicle (RV). When determining
your cooling requirements, the following should be consid-
ered:
1. Size of RV;
2. Window area (increases heat gain);
3. Amount of insulation in walls and roof;
4. Geographical location where the RV will be used;
5. Personal comfort level required.
Improper installation may damage equip-
ment, could endanger life, cause serious
injury and/or property damage.
A. For One Unit Installation:
The air conditioner/heat pump 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/heat pump one-third and one
air conditioner/heat pump two-thirds from front of RV and
centered from side to side.
It is preferred that the air conditioner/heat pump be installed
on a relatively flat and level roof section measured with the
RV parked on a level surface; however,
1.
Up to an 8° slant to either side or front-to-back is
acceptable on 600 and 630 Series Air Condition-
ers/heat pump.
2.
Up to a 15° slant to either side or front-to-back is
acceptable on 579, 590, 591 or 595 Series Air
conditioners/heat pump.
AFTER LOCATION HAS BEEN SELECTED:
a. Check for obstructions in the area where air
conditioner/heat pump will be installed. See
FIG. 1.
b. The roof must be designed to support 130
pounds when the RV is in motion. Normally 200
pound static load design will meet this require-
ment.

WARNING
!
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.
