17 mm (21/32 in.) wrench and torque wrench
A length of 3.31 mm² (12 AWG) copper wire to ground the
radar housing (and voltage converter, if applicable).
• Marine sealant
When selecting a mounting location, observe these
considerations.
• It is highly recommended that the device is mounted out of
range of people, with the vertical beam width above head
height. To avoid exposure to harmful radio frequency (RF)
levels, the device should not be mounted closer to people
than the maximum safe distance value listed in the product
specifications.
• The device should be mounted high above the ship’s keel
line with minimal blockage of the radar beam. Obstructions
may cause blind and shadow sectors or generate false
echoes. The higher the installation position, the farther the
radar can detect targets.
• The device should be mounted on a flat surface or a platform
that is parallel to the vessel's water line and is sturdy enough
to support the device's weight. The weight for each model
and antenna is listed in the product specifications.
• The device must be mounted in a location where it can be
connected to power, water ground, and the Garmin Marine
Network (Wiring and Connection Considerations, page 3).
• The radar beam spreads vertically 11.5° above and
11.5° below À the radar's radiating element. On vessels with
higher bow angles at cruise speed, the installation angle can
be lowered to point the beam slightly downward to the
waterline while at rest. Shims can be used if necessary.
• The device should be mounted away from heat sources, such
as smoke stacks and lights.
• The device should be mounted at a different level than
horizontal spreaders and mast crosstrees.
• To avoid interference with a magnetic compass, the device
should not be mounted closer to a compass than the
compass-safe distance value listed in the product
specifications.
• Other electronics and cables should be mounted more than
2 m (6.5 ft.) from the radar beam path.
• GPS antennas should be either above or below the radar
beam path.
• The device should be mounted at least 1 m (40 in.) from any
transmitting equipment.
• The device should be mounted at least 1 m (40 in.) away
from cables carrying radio signals such as VHF radios,
cables, and antennas.
• The device should be mounted at least 2 m (6.5 ft.) away
from Single Side Band (SSB) radios.
Installation Procedures
Preparing the Surface and the Radar for Mounting
Before you can mount the radar, you must choose a suitable
mounting location (Mounting Considerations, page 1).
1 Secure the included mounting template to the surface at the
mounting location, along the bow-stern axis, as indicated on
the template.
2 Drill the mounting holes using a 15 mm (19/32 in.) drill bit.
3 If you need to run the power and network cables through the
mounting surface, select a location under the power and
network connectors indicated on the template, drill a pass-
August 2018
190-01818-02_0D
through hole for the cables using a 32 mm (11/4 in.) drill bit,
and route the cables through the surface (optional) (Wiring
and Connection Considerations, page 3).
4 Remove the mounting template from the surface.
5 Remove the hatch on the front of the pedestal by loosening
the screw and lifting the hatch off of the hinges.
4 Place the flat washers Á, lock washers Â, and hex nuts à on
the threaded rods.
5 Torque the hex nuts to 1.5 kgf-m (130 lbf-in. [11 lbf-ft.]) to
securely fasten the radar to the surface without damaging the
radar or the mounting hardware.
Installing the Antenna
Before you can install the antenna on the radar, you must
securely mount the pedestal (Mounting the Radar, page 2).
1 Remove the protective cover À from the waveguide on the
top of the pedestal.
6 Apply the included Petrolatum Primer to one half of the
threads of the four threaded rods.
7 Insert the ends of the threaded rods coated in Petrolatum
Primer into the pedestal.
8 Tighten the threaded rods using a 5 mm hex wrench.
To avoid damaging the pedestal, you should stop tightening
the threaded rods when they no longer turn easily.
2 Align the waveguide Á on the pedestal with the socket on the
bottom of the antenna Â, and slide the antenna onto the
pedestal.
Mounting the Radar
Before you can mount the radar, you must first select a
mounting location, and prepare the mounting surface and the
radar (Preparing the Surface and the Radar for Mounting,
page 1).
1 Take note of which end of the pedestal you plan to mount
facing the bow along the bow-stern axis.
If the hatch side is facing the bow, you must adjust the frontof-boat offset on the chartplotter to receive an accurate radar
reading (Front-of-Boat Offset, page 4).
2 Hoist the radar into position, and carefully lower it onto the
mounting surface, feeding the threaded rods through the
holes.
3 From under the mounting surface, place the shoulder
washers À on the threaded rods and feed them into the
mounting surface so they fit securely.
2
3 Secure the antenna to the pedestal using the included hex
bolts à and spring washers Ä.
4 Torque the hex bolts to 0.81 kgf-m (70 lfb-in. [6 lbf-ft.]) to
fasten the antenna to the pedestal without damaging the
antenna or the mounting hardware.
Wiring and Connection Considerations
It may be necessary to drill 32 mm (11/4) in. holes for routing the
power, network, or grounding cables.
• When routing multiple cables through the same hole, you
must route the network cable before the power and ground
cables because of the size of the network connector.
• You must apply marine sealant to the hole after the cables
are in place to ensure a waterproof seal.
If you must make the routing hole in a visible location,
decorative cable grommets can be purchased from Garmin or a
Garmin dealer (optional).
• If needed, you can trim the grommet to enable you to route
multiple cables through the same hole.
• The optional grommet does NOT provide a waterproof seal.
You must apply marine sealant to the grommet after the
cables are in place to ensure a waterproof seal.
When installing the cables, you should observe these
considerations.
• Cutting the Garmin Marine Network cable is not
recommended, but a field install kit can be purchased from
Garmin or a Garmin dealer if you must cut the network cable.
• The ground cable is not included, and must connect to a
water ground location, not the negative terminal of the battery
(Grounding the Radar, page 4).
• To ensure safety, appropriate tie-wraps, fasteners, and
sealant should be used to secure the cable along the route
and through any bulkheads or the deck.
• You should not run cables near moving objects and high-heat
sources, or through doorways and bilges.
• To avoid interference with other equipment, you should not
run network and power cables parallel to other cables, such
as radio antenna lines or power cables. If this is not possible,
the cables should be shielded with metal conduit or a form of
EMI shielding.
• You should install the power cable as close to the battery
source as possible.
◦ If it is necessary to extend the power cable, you must use
the appropriate wire gauge (Power Cable Extensions,
page 4).
◦ Incorrectly extended runs of cable may cause the radar to
malfunction due to insufficient power transmission.
Connecting to Power Through the Voltage Converter
WARNING
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
NOTICE
Do not reuse any voltage converters from previous Garmin radar
models, or third party voltage converters. Using any converter
other than one included with the radar may damage the radar or
prevent it from turning on.
When installing the voltage converter for an applicable radar
model, observe these considerations.
• The voltage converter requires an input voltage of 10 to
32 Vdc.
• It is recommended to install the voltage converter as close as
possible to the power source.
• Connecting the power cable for the voltage converter directly
to the battery is recommended. If it is necessary to extend
the cable, the appropriate gauge of wire must be used for the
length of the extension (Power Cable Extensions, page 4).
