A. Choosing Proper Location For Unit
This unit is specifically designed for installation on the roof
of a boat. Mount only with front of unit facing the bow (the
vented end should face aft). See “FIG. 4” on page (6).
When determining your cooling requirements, the following
should be considered:
●
Size of boat;
●
Window area (increases heat gain);
●
Amount of insulation in walls and roof;
●
Geographical location where boat will be used;
●
Personal comfort level required.
It is preferred that the unit be installed on a relatively flat
and level roof section. See table below for maximum ac-
ceptable tilt.

b.
Maintain structural integrity.
Otherwise damage to product and/or boat
could occur.
The roof must be designed to support 60
kg when the boat is in motion. Normally
a 60 kg static load design will meet this
requirement.
c. Check inside the boat’s cabin for air distri-
bution box (hereinafter referred to as “ADB”)
obstructions (i.e. space for doors to open,
room dividers, curtains, ceiling fixtures, etc.).
See (FIG. 2).

B. Roof Preparation
1.
FIRE OR ELECTRICAL SHOCK
HAZARD. Verify there are no obstacles inside
boat’s roof and/or walls (wires, pipes, etc.). Shut
OFF
gas supply, disconnect 220-240 Vac power
from boat, and disconnect positive (+) 12 Vdc
terminal from supply battery
BEFORE
drilling or
cutting into boat. Failure to obey these warnings
could result in death or serious injury.
Opening Requirements - Before prepar-
ing the ceiling opening, read all of the fol-
lowing instructions before beginning the
installation.
2. Carefully mark and cut the required roof opening.
See “C. Roof Requirements” on page (4).
3.
Maintain structural integrity. Oth-
erwise damage to product and/or boat could oc-
cur.
NEVER
create a low spot on boat
roof. Otherwise, water will pool and could cause
a leak.
Using the roof opening as a guide, cut the match-
ing hole in the ceiling.
The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Framing stock 19 mm
or more in thickness must be used. Remember
to provide an entrance hole for power supplies
at the front of the opening. See (FIG. 3).
