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, but up to a 8° tilt is acceptable.
3. After Location Has Been Selected:
a. Check for obstructions in the area where unit
will be installed. See (FIG. 1).

b. Maintain structural integrity.
Otherwise damage to product and/or RV
could occur.
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 re-
quirement.
c. Check inside the RV for air distribution box
obstructions (i.e. door openings, room di-
viders, curtains, ceiling xtures, etc.) See
(FIG. 2).

B. Roof Preparation
1. FIRE OR ELECTRICAL SHOCK
HAZARD. Verify there are no obstacles inside
RV roof and/or walls (wires, pipes, etc.). Shut
OFF gas supply, disconnect 120 Vac power from
RV, and disconnect positive (+) 12 Vdc terminal
from supply battery BEFORE drilling or cutting
into RV. Failure to obey these warnings could
result in death or serious injury.
Opening Requirements - Before preparing
the ceiling opening, the type of system op-
tions MUST be decided upon. Read all of
the following instructions before beginning
the installation.
Carefully mark and cut the required roof open-
ing. See section, "B. Roof Requirements" on
page (4).
2. Using the roof opening as a guide, cut the match-
ing hole in the ceiling.
3. Maintain structural integrity. Oth-
erwise damage to product and/or RV could oc-
cur.
NEVER create a low spot on RV
roof. Otherwise, water will pool and could cause
a leak.
The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Framing stock 3/4″or
more in thickness must be used. Remember to
provide an entrance hole for power supplies, 3
conductor cable, and furnace wiring (if applica-
ble). See (FIG. 3).
