8.4 Selecting an installation location

roof top unit and the ceiling assembly without additional support.
Make sure the interior ceiling mounting area will not interfere with
existing structures.
Once the location for the air conditioner has been determined. A
reinforced and framed roof hole opening must be cut (if there is no
hole,please refer to CASE B) or you may use existing vent holes
(See CASE A).

the air conditioner, the following steps must be performed:
1.Remove all screws which secure the roof vent to the vehicle.
Remove the vent and any additional trim. Carefully remove all
chalking from around the opening so the surface is clear.
2.It may be necessary to seal some of the old roof vent mounting
screw holes which may fall outside of the air conditioner basepan
