VEHICLE.
Once the location for your heat pump has been determined
(See Section III), a reinforced and framed roof hole opening
must be provided (may use existing vent hole). Before cutting
into the vehicle roof, verify that the cutting action will clear
all structural members and crossbeams. Additionally, the
location of any inner roof plumbing and electrical supplies
must be considered.
A.
If a roof vent is already present in the desired
mounting location for the heat pump, the following
steps must be taken:
1.
Remove all screws which secure the roof
vent to the vehicle. Remove the vent and
any additional trim materials. Carefully
remove all chalking from around the roof
vent opening to obtain clean exterior roof
surface.
2.
It may be necessary to seal some of the old
roof vent mounting screw holes which may
fall outside of the heat pump basepan
gasket.
3.
Examine the roof opening. If the opening is
smaller than 14" x 14", the opening must be
enlarged (See Figure 1).
B.
If a roof vent opening is not used, a new opening
(See Figure 1) will have to be cut into the vehicle
roof. A matching opening will also have to be cut
into the interior vehicle ceiling. Be careful when
cutting the ceiling opening. If the ceiling opening
is carpeted, snagging could occur. After the opening
in the roof and interior ceiling are the correct size,
a framed support structure must be provided between
exterior roof top and interior ceiling. The reinforced
framed structure must provide the following
guidelines:
1.
Capable of supporting both the weight of
the roof top heat pump and the interior
ceiling assembly.
2.
Capable of holding or supporting the roof
outer surface and interior ceiling apart, so
that when the roof top heat pump and
ceiling assembly are bolted together, no
collapsing occurs.

The frame must provide an opening to allow passage
for the power supply wiring. Route the supply
wiring through the frame at the same time the
support frame is being installed.
C.
This heat pump is to be installed in accordance
with NFPA Standard 501C.
D.
The roof top heat pump must be mounted as
near level from front to rear and side to side as is
possible when the vehicle is parked on a level plane.
Figures 2 and 3 show maximum allowable degree
deviations (mounting degrees from total surface flat
plane).
