Installation And Setup; Installation - Navman WIND 3100 Installation And Operation Manual

8 Installation and setup

Correct installation is critical to the performance of
the unit. It is vital to read this section of the manual
and the documentation that comes with the other
parts before starting installation.
The WIND 3100 can:
Drive external beepers or lights for the alarm.
Send and receive data from other NAVMAN
instruments connected via NavBus. Settings
for alarms, units, calibration and backlighting
are shared (see section 6-1).
Send and receive NMEA data to and from other
instruments (see section 6-2).
Warnings
The unit is waterproof from the front. Protect the rear
of the unit from water, or else water might enter the
breathing hole and damage the unit. The warranty
does not cover damage caused by moisture or water
entering the back of the unit.
The cable up the mast to the masthead unit must
run in conduit.
Ensure that any holes that you cut will not
weaken the boat or the mast. If in doubt,
consult a qualified boat builder or marine
engineer.

8-1 Installation

WIND 3100 display unit
1 Choose a location for the display unit that is:
Easily seen and protected from damage.
At least 100 mm from a compass and at
least 500 mm from a radio or radar
antenna.
Away from engines, fluorescent lights, and
power inverters.
Accessible from behind; the minimum
clearance required at the back is 50 mm
(2") (see mounting diagram).
With the back of the unit protected from
moisture.
2 The unit must mount on a flat panel which is
less than 20 mm (0.75") thick. Stick the
mounting template in place. Drill a 50 mm (2")
fixing hole through the centre hole in the
template. Note that the template allows space
around the unit for the protective cover.
3 Remove the fixing nut from the back of the unit.
Insert the stud at the back of the unit through the
mounting hole. Hand tighten the fixing nut.

Masthead unit
Plan the installation. Read through these instructions
before you install the masthead unit and plan where
you will fit the mounting block and where you will
drill the cable holes in the mast. It is usually easiest
to install the masthead unit when the rig is off the
boat.
1 The mounting block is at one end of the 30 m
(90 ft) masthead cable. Fit the mounting block
on top of the mast:
With the base of the block horizontal.
With the fitting for the masthead arm facing
forward, parallel to the centre line to within
a few degrees (if the arm does not face
exactly forward, the wind direction will need
to be aligned, see section 3-4).
Use the self-tapping screws provided.
Forward
2 Drill an 8 mm (5/16") hole at the top of the
mast close to the mounting block for the cable
to enter the mast. Do not install the masthead
cable yet.
3 Drill an 8 mm (5/16") hole at the bottom of the
mast at a convenient place for the cable to exit
the mast. You will fit the cable junction box
close to this hole; it should be in a dry place
and not in the bilge.
