MOUNTING INSTRUCTIONS
Reminder:
To prevent personal injury, disconnect one of the main battery
leads prior to installing the blower.
1. Select a flat mounting surface high above the bilge, on the
transom or under the deck. Blower should be mounted high
and dry, clear of moisture from spray or deck wash.
2. Position blower with fan nose cone pointing toward exhaust
vent. Also, mount blower at an angle to prevent moisture
build-up. See Figure 1
3. Mark mounting holes using blower mounting feet as a tem-
plate. Drill holes for #10 screws.
4. Secure unit in place using stainless steel screws. Do not over
tighten screws, as this will crack the mounting feet.
5. Twist duct hose over exhaust and intake openings on blower.
Ensure the retainer tabs engage corrugated rings of hose.
6. Install tie strap or hose clamp on the hose. Position the strap or
clamp around blower housing, beyond the tabs. Tighten the
strap. When using a hose clamp, tighten until snug — 8 in/lb.
(.5N
. m) max. Do not overtighten straps or clamps.
7. Route intake end of hose directly to the lowest point in the
bilge, with as few bends as possible. The hose pick-up must
be below the top of the engine stringers, but not low enough
to become submerged in normal bilge water accumulation.
See Figure 1
8. Route exhaust end of hose directly to vent or vent collector
box, with as few bends as possible. Connect hose securely
to vent. See Figure 1

FEATURES

ments, bilges, and marine head closets. Their unique fan blade is
computer-designed using the latest in aerospace technology.
The blowers’ compact in-line design allows for installation in
confined areas under the deck or on the transom; their built-in
mounting feet allow vertical or horizontal installation. Tabs on the
