CASE B.
If a roof vent opening is not used,a new opening(see figure 1)will be cut into the vehicl 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 follwing guidelines:
Figure 1
CAUTION
1.
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 unit can be mounted above or below level.
2.
If the roof of the vehicle is sloped (not level) such that the roof top air cannot be mounted within the maximum allowable
degree specifications, an exterior leveling shim will need to be added to make the unit level. A typical leveling shim is
shown in Figure 3.
3.
Once the roof top air conditioner has been leveled, some additional shimming may be required above the interior ceiling
assembly. The roof top air conditioner and the interior ceiling assembly must be square with each other before they are
secured together.
4.
After the mounting hole area is properly prepared, remove the carton and shipping pads from around the roof top air
conditioner. Carefully lift the unit on top of the vehicle. Do not use the outer plastic shroud for lifting. Place the roof top
air conditioner over the prepared mounting hole.
5.
The point end (nose) of the shroud must face toward the front of the vehicle.

1. It must be capable of supporting both the weight of the
roof top air conditioner and the interior ceiling assembly.
2. 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. Atypical support
frame is shown in Figure 1.
3. 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.
4. For roof cutouts larger than 365 x 365 mm, the optional
adapter frame must be used on the outside in addition to
the support frame. A butyl sealing cord or butyl sealing
agent should be used to seal the adapter frame.
