C. POST LOCATION SELECTION:
1. Check for obstructions in the area where air conditioner / heat pump will be installed.
A minimum clearance of 18” is required for the rear section of the air conditioner / heat
pump to any other roof mounted object.
2. The roof must be capable of supporting 100 lbs while the RV is in motion. Normally,
a 200 lb. static load design will meet this requirement.
3. ROOF PREPARATION
A. EXISTING ROOF VENT REMOVAL:
1. Unscrew and remove the roof vent.
2. Remove all caulking compound around opening.
3. Seal all screw holes and seams where the roof gasket will be located. Use a good
grade of all weather sealant.
B. NEW OPENING:
1. A 14-1/4" x 14-1/4"±1/8” opening must be cut through the roof and ceiling of the RV.
It is recommended this opening be located between roof framework.
2. Mark a 14-1/4" x 14-1/4" square on the roof and carefully cut the opening.
3. Using the roof opening as a guide, cut the matching hole in the ceiling. See FIG.4.
