Installation Instructions
Caution
Using ordinary electric tools near water is VERY dangerous! To minimize the dangers of
electric shock and personal injury, we recommend using only cordless rechargeable tools,
and/ or hand tools, during the installation of the system.
1420 Autopilot System
Allow at least a foot (30 cm) of clearance
on either end of the Processor in the
space where it is to be located.
Planning
Processor Location
In choosing a location for your ComNav
1420 Autopilot System, remember that
the cable from the Control Head to the
Processor (Cable #1) should not be cut or
lengthened. Excess cable may be
loosely coiled behind a panel.
Do not mount the Processor near heat
sources, such as heat radiators, or over
engines.
If you can, mount the Processor so that
the cooling fins are vertical.
You will want to have the Control Head
near the steering station you use the
most; place the Mounting Clip at this
station. Also note the following, when you
plan the routing of cable #1:
If possible, mount the Processor where
you will be able to hear its internal beeper
while operating your boat. Although the
lights on the Control Head will tell you
about the Autopilot's actions, it helps if
you can hear the beeper too.
- Cable #1 is 25 feet (7.7 m) long, and
is permanently attached to the
Control Head.
Compass Location
When choosing a location for the
Compass, try to locate it as close as
possible to the most stable spot on your
boat. Usually this spot will be close to the
water line level, in the middle of the boat
and two-thirds towards the stern from the
bow.
- If you are intending to move the
Control Head around, in order to use
it in other locations, locate the
Processor so that the Head’s cable
will also be able to reach those other
locations.
Similarly, the cable from the Compass to
the Processor (Cable #2), should not be
cut or lengthened. Cable #2 is 40 feet
(12.2 m) long (excess may be coiled up).
Do not install your Compass near wires or
devices carrying large electric currents
such as battery chargers, electric pumps
and motors or televisions.
Do not mount your Compass near any
iron or steel objects.
