Installing the Day/Night PLUS
3
If you have only one vent installed on your boat, we recommend
using the exhaust fan blade; if you have multiple vents, try different
configurations of intake and exhaust to achieve effective cross flow
ventilation.
INSECT SCREEN
Your new vent comes with a removable insect screen that attaches
to the shut-off damper. Installation of the insect screen is optional.
The screen is easy to install by grasping the fin in the center and
carefully twisting it in a clockwise motion. Make sure to clean the
insect screen periodically to ensure maximum air flow.
INSTALL PRECAUTIONS
DECK CAMBER (OR DECK
CURVATURE) is VERY CRITICAL: When
installing the Day/Night PLUS Vent on a
cambered, or curved, surface, it is critical
to check to make sure there is no more
than 1/2" (12mm) of camber over a 12"
(300mm) length of deck surface. Too
much camber will distort the unit’s base
plate, causing the cover to be raised off
the deck. This creates the potential for water to get under the cover
and may also prevent the damper from closing properly.
To check for camber, place a 12" (300mm) straightedge on the
deck location for the vent and try to rock it. Then rotate it 90
degrees and repeat.
AVOID PROBLEM
Cut the hole for your Day/Night PLUS only after carefully considering
the location and the correct sizing of the hole. We recommend that
you
MEASURE TWICE AND CUT ONCE!
DO NOT Install the Day/Night PLUS in an area with more than 1/2"
of camber over a 12" length of deck surface.
CAUTION Confirm the location you select for the through-
deck hole does not go through any electrical wiring, plumbing
