CASE 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 because
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 placed between the exterior roof top and interior ceiling. The
reinforced framed structure must follow the following guidelines:
Hole for Wires
• Allow 24” (working length) of supply wiring through the support frame and make sure that all wiring passing
through any mechanical structure must be protected from insulation chaffing using a rubber grommet or strain
relief.
• After the support frame is built and both the roof exterior and the interior ceiling are cut, make sure that the
electrical wiring can be routed to the control board. Seal the gap around the electrical supply wiring using a
rubber grommet.
• The roof top air conditioner must be mounted on a level plane from front to rear and side to side when the vehicle
is parked on a level plane. Figure 2 shows maximum allowable degrees that the Air V can be mounted above or
below level.

It must be capable of supporting both the weight
of the roof top air conditioner and the interior
ceiling assembly
It must be capable of holding the roof outer
surface and interior ceiling apart and supporting
them, so that when the roof top air conditioner
and ceiling assembly are bolted together, no
collapsing occurs.
We recommend that the spacing between the
vehicle roof top and the interior ceiling top be no
less than 3/4”. A typical support frame is shown in
Figure 1.
There must be an opening through the frame for
the power supply wiring. Route the supply wiring
through the frame at the same time the support
frame is being installed.
