GHP 10 Installation Instructions
5
Installation Preparation
Before installing the GHP 10 autopilot system, you must plan where all
the components will be located on your boat. Temporarily place all the
components where you intend to install them. Read these considerations
before you begin planning your
installation.
NOTE:
There is an installation checklist on the last page of these
instructions. Remove the last page and refer to the checklist as you
proceed through the GHP 10 installation.
Mounting and Connection Considerations
The GHP 10 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 connecting any components.
Shadow Drive Mounting Considerations
• Mount the Shadow Drive horizontally and as level as possible, using
cable ties to firmly secure it in place.
•
Mount the Shadow Drive at least 12 in. (0.3 m) away from
magnetic material such as speakers and electric motors,
including the autopilot pump.
• Install the Shadow Drive closer to the helm than to the pump.
• Install the Shadow Drive lower than the helm, but higher than the
pump.
• Avoid making loops in the hydraulic lines.
• Do not install the Shadow Drive directly to the fittings at the back of
the helm. Install a length of hose between the fitting at the helm and
the Shadow Drive.
• Do not install the Shadow Drive directly to a hydraulic T-connector
in the hydraulic line. Install a length of hose between a
T-connector and the Shadow Drive.
•
In a single-helm installation, do not install a T-connector
between the helm and the Shadow Drive.
•
In a dual-helm installation, install the Shadow Drive between
the pump and the lower helm, closer to the helm than to the
pump.
• Install the Shadow Drive in either the starboard steering line or the
port steering line.
Do not install the Shadow Drive in the return
line.
• Do not use Teflon tape on any hydraulic fitting. Use an appropriate
thread sealant such as Loctite Pro Lock Tight multipurpose
anaerobic gel, part number 51604, or equivalent, on all pipe threads
in the hydraulic system.
ECu Mounting Considerations
• The ECU can be mounted on a flat surface facing any direction.
• Mounting screws are included with the ECU, but you may need to
provide different screws if the supplied screws are not suitable for
the mounting surface.
• The ECU must be located within 19 in. (0.5 m) of the drive unit.
• The ECU must not be mounted in a location where it will be
submerged or exposed to wash-down.
ECu Connection Considerations
• The ECU power cable connects to the boat battery, and it can be
extended if needed (
• ECU units with a serial number prior to 19E002748 are only
compatible with 12 Vdc systems.
ECU units with a serial number of 19E002748 or later are
compatible with both 12 Vdc and 24 Vdc systems.
•
The cables connecting the pump to the ECU cannot be extended.
Hydraulic Considerations for avoiding ECu Drive Circuit
overload
• Ensure the appropriate pump has been correctly installed on your
boat.
NOTE
: If you have questions about the appropriate pump for your boat,
contact your local Garmin dealer or Garmin Product Support for more
information.
• If possible, use larger inside diameter hydraulic hoses on your
steering system.
• Mount the pump closer to the cylinder to limit the length of the hose
runs.
• Eliminate unneeded hydraulic fittings in the hydraulic fittings.
CCu Mounting Considerations
•
The CCU must be mounted in the forward half of the boat, no
higher than 10 ft. (3 m) above the waterline.
• The CCU must not be mounted in a location where it will be
submerged or exposed to wash-down.
•
The CCU must not be mounted near magnetic material,
magnets (speakers and electric motors), or high-current wires.
• The CCU must be mounted at least 24 in. (0.6 m) away from
movable or changing magnetic disturbances such as anchors, anchor
chain, wiper motors, and tool boxes.
• A handheld compass should be used to test for magnetic interference
in the area where the CCU is to be mounted.
If the handheld compass does not point north when you hold it in
the location where you intend to mount the CCU, there is magnetic
interference. Choose another location, and test again.
• The CCU can be mounted below the waterline if it is not in a
location where it will be submerged or exposed to wash-down.
• The CCU bracket must be mounted on a vertical surface or under a
horizontal surface, so that the connected wires hang straight down.
• Mounting screws are included with the CCU, but you may need to
provide different screws if the supplied screws are not suitable for
the mounting surface.
CCu Connection Considerations
• The CCU/ECU interconnect cable connects the CCU to the ECU
and is 16 ft. (5 m) long.
◦ If the CCU cannot be mounted within 16 ft. (5 m) of the ECU,
replacement and extension cables are available (
).
◦
The CCU/ECU interconnect cable must not be cut.
• The CCU/ECU interconnect cable connects the CCU to the GHC 10
with a single yellow signal wire (
). The autopilot system
does not power on if this connection is not made.
alarm Mounting Considerations
• The alarm should be mounted near the helm station.
• The alarm can be mounted under the dashboard.
alarm Connection Considerations
• If needed, the alarm wires can be extended with 28 AWG (.08 mm
2
)
wire.
