enlarged. If the opening exceeds 15” x 15”,
a mounting frame must be field fabricated to
reduce the opening size (See Figure 1).
2. 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:
a. Capable of supporting both the weight of the roof
top Heat Pump and the interior ceiling assembly.
b. 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.
Airxcel’s 45000 series requires that the spacing from the
vehicle roof top to the interior ceiling be no less than 1”.
A typical support frame is shown in Figure 1.
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.
IMPORTANT – Allow 24” of supply wiring through
the support frame (working length).
After the support frame is installed, seal off all gaps
between the frame and both the roof exterior and the
interior ceiling of the vehicle (cavity walls). Additionally,
seal the gap around the electrical supply wiring.
3. 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. Figure
3 shows maximum allowable degree deviations
(mounting degrees from total surface flat plane).
If the roof of the vehicle is sloped (not level) such
that the roof top Heat Pump cannot be mounted
within the maximum allowable degree deviations, an
exterior leveling shim will need to be added to make
the roof top Heat Pump level. A typical leveling shim
is shown in Figure 2.
4. After the mounting hole area is properly prepared,
remove the carton and shipping pads from the roof
top Heat Pump. Carefully lift the unit to the top of
the vehicle. Do not use the outer plastic shroud for
lifting. Place the roof top Heat Pump over the prepared
mounting hole. The pointed end (nose) of the shroud
must face towards the front of the vehicle. Pull the
electrical conduit down from the Heat Pump through
the mounting opening and let hang.
5. Securing the Heat Pump to the Roof - A mounting
frame is supplied with the ceiling assembly. Follow
the steps below to secure the Heat Pump to the roof.
Refer to Figure 4.
a. Locate the Heat Pump mount gasket over the 14” to
15” square opening in the roof.
b. Install the ceiling assembly mount frame using the
four bolts found with the ceiling assembly.
c. Proper tension has been achieved for each bolt
when any portion of each gasket indicating tab has
been pulled down even with the roof. See Figure 4.
The upper unit has now been properly installed with
optimum gasket compression.
