installed. A minimum clearance of 18" is required for the rear section of the air
conditioner / heat pump to any other roof mounted object.

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.3.
There may be electrical wiring between the roof and
the ceiling. Disconnect 120 volt AC power cord and the
positive (+) 12 volt DC terminal at the supply battery.
