Important Safety Information
WARNING
See the
Important Safety and Product Information
guide in the
product box for product warnings and other important
information.
You are responsible for the safe and prudent operation of your
vessel. The autopilot is a tool that enhances your capability to
operate your boat. It does not relieve you of the responsibility of
safely operating your boat. Avoid navigational hazards and
never leave the helm unattended.
Always be prepared to promptly regain manual control of your
boat.
Learn to operate the autopilot on calm and hazard-free open
water.
Use caution when operating the autopilot near hazards in the
water, such as docks, pilings, and other boats.
CAUTION
When in use, beware of hot motor and solenoid components
and the risk of entrapment from moving parts.
Failure to install and maintain this equipment in accordance with
these instructions could result in damage or injury.
NOTICE
To avoid damage to your boat, the autopilot system should be
installed by a qualified marine installer. Specific knowledge of
hydraulic steering componentry and marine electrical systems is
required for proper installation.
Installation Preparation
The autopilot system consists of multiple components. You
should familiarize yourself with all of the component mounting
and connection considerations before beginning installation. You
must know how the components operate together in order to
correctly plan the installation on your boat.
You can consult the layout diagrams (
Power and Data Layout
,
page 3
) to help understand the mounting and connection
considerations.
You should lay out all of the components on the boat as you
plan the installation to make sure your cables will reach each
component.
You should record the serial number of each component for
registration and warranty purposes.
Tools Needed
• Safety glasses
• Drill and drill bits
• Wrenches
• 90 mm (3.5 in.) hole saw or a rotary cutting tool (for installing
an optional helm control)
• Wire cutters/strippers
• Phillips and flat screwdrivers
• Cable ties
• Single Pole Single Throw (SPST) switch (to use as an
autopilot bypass when not installing the Shadow Drive
™
valve)
• Waterproof wire connectors (wire nuts) or heat-shrink tubing
and a heat gun
• Marine sealant
• Marine corrosion inhibitor spray
• Portable or handheld compass (to test for magnetic
interference)
• Hydraulic hose with machine-crimped or field-replaceable
fittings that have a minimum rating of 1000 lbf/in
2
• Hydraulic T-fittings
• Inline hydraulic shut-off valves
• Hydraulic fluid
• Thread sealant
• Hydraulic bleeding equipment
• Anti-seize lubricant (optional)
NOTE:
Mounting screws are provided for the main components
of the autopilot system. If the provided screws are not
appropriate for the mounting surface, you must provide the
correct types of screws.
Mounting and Connection Considerations
The autopilot components connect to each other and to power
using the included cables. Ensure that the correct cables reach
each component and that each component is in an acceptable
location before mounting or wiring any components.
Helm Control Mounting Considerations
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000
®
network as a compatible Garmin chartplotter to
configure and control the autopilot system.
NOTICE
This device should be mounted in a location that is not exposed
to extreme temperatures or conditions. The temperature range
for this device is listed in the product specifications. Extended
exposure to temperatures exceeding the specified temperature
range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.
The mounting surface must be flat to avoid damaging the device
when it is mounted.
Using the included hardware and template, you can flush mount
the helm control in the dashboard. When selecting a mounting
location, observe these considerations.
• The mounting location should be at or below eye level to
provide optimal viewing as you operate your vessel.
• The mounting location should allow easy access to the keys
on the device.
• The mounting surface must be strong enough to support the
weight of the device and protect it from excessive vibration or
shock.
