DEPTH 3100 Installation and Operation Manual
NAVMAN
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 DEPTH 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 4-1).
Send and receive NMEA data from other
instruments (see section 4-2).
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.
Ensure that any holes that you cut will not weaken
the boat’s structure. If in doubt, consult a qualified
boat builder.
6-1 Installation
DEPTH 3100 display unit
1 Choose a location for the display unit that is:
Easily seen and protected from damage.
At least 100 mm (4") from a compass and
at least 500 mm (1.65 ft) from a radio or
radar antenna.
Away from engines, fluorescent lights, and
power inverters.
Accessable 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.
6 Installation and setup
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.
Transducers
1 If the DEPTH 3100 does not come with a
transducer, choose a suitable transducer (see
section 5-3). If the DEPTH 3100 is supplied
with a transducer, see section 5-3 to ensure
that it is suitable.
2 Choose a suitable location for the transducer
and install it by following the instructions in the
Transducer Installation manual.
3 Fit the cables between the transducer and the
display unit:
Keep the cable away from other cables,
engines, fluorescent lights, power inverters
and radio or radar transmitters.
Ensure no connectors lay in the bilge.
If necessary, extend the cable by adding
extension cables.
Do not cut the cable on any depth
transducer.
Secure the cable at regular intervals.
4 Connect the transducer to the display unit
connector.
The choice, location, angle and installation of
the transducers is the most critical part of the
installation. If they are not correct, the unit can
not perform at its designed potential. If in
doubt, consult your NAVMAN dealer. Plastic
through hull transducers are usually unsuitable
for wood hulls. If in doubt, consult a marine
surveyor or marine engineer.
