PRECAUTIONS
C. AFTER LOCATION HAS BEEN SELECTED:
1.
Check for obstructions in the area where air condi-
tioner/heat pump and return air cover will be in-
stalled.
2.
The roof must be designed to support 130 pounds
when the RV is in motion. Normally a 200 lbs. static
load design will meet this requirement.

before attempting to start your air conditioner installa-
tion.
B. Dometic Corporation will not be liable for any damages
or injury incurred due to failure in following these instruc-
tions.
C. Installation must comply with the National Electrical

2. CHOOSING LOCATION FOR THE UNIT
This air conditioner/heat pump is specifically designed for
installation on the roof of a recreational vehicle (RV).
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 two-thirds from front of RV and centered
from side to side. It is preferred that the air conditioner/
heat pump be installed in a relatively flat and level roof
section measured with the RV parked on a level surface.
Improper installation may damage equip-
ment/could endanger life, cause serious in-
jury and/or property damage.
WARNING
!
3. AIR DISTRIBUTION SYSTEM SIZING &
DESIGN
The Installer of this air conditioner/heat pump system must
design the air distribution system for his particular applica-
tion. Several requirements for this system MUST be met for
the air conditioner/heat pump to operate properly. These
requirements are as follows:
A. Roof cavity thickness must be between 2.00" to 5.50".
This distance is measured between roof and ceiling
surface.
B. The total cross-sectional discharge area of outlet ducts
from the plenum area under the air conditioner/heat
pump must be a minimum o
f 16.0
sq. inches each side.
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 inte-
rior causing damage to the product and the
RV.
