If the opening exceeds 362mm x 362mm
(± 3.2mm), it will be necessary to re-size the
opening to 362mm x 362mm (± 3.2mm).
e.
If the opening is less than 362mm x 362mm
(± 3.2mm), it must be enlarged.
3. New Opening- (Installation Other Than Vent Open-
ing)
a.
Mark a 362mm x 362mm (± 3.2mm) square on
the roof and carefully cut the opening.
b.
Using the roof opening as a guide, cut the
matching hole in the ceiling.
c.
The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Lumber 25mm or
more in thickness must be used. Remember to
provide an entrance hole for power supplies at
the front of the opening. See FIG. 7.
It is the responsibility of the installer of this
air conditioner system to ensure structural
integrity of the Caravan roof. Never create a
low spot on the roof where water will collect.
Water standing around the air conditioner may
leak into the interior causing damage to the
product and the Caravan.

portion of the 362mm x 362mm (± 3.2mm)
opening.
b.
The power MUST be on a separate 10 Amp time
delay fuse or HACR circuit breaker.
c.
Make sure that at least 375mm of supply wire
extends into the roof opening. This ensures an
