WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment
unless totally familiar with
electrical circuits and service
manual.
Only qualified personnel should
work inside the equipment.
WARNING
Install the specified transducer tank
in accordance with the installation
instructions. If a different tank is to be
installed the shipyard is solely respon-
sible for its installation, and it should
be installed so the hull will not be
damaged if the tank strikes an object.
The tank or hull may be damaged if the
tank strikes an object.
When assembling the hull unit, fasten
the shaft retainer and fastening band
with the torques shown below.
Shaft retainer: 20 to 25 N m
Jubilee clip: 6 to 8 N m
If torques are less than the above,
water leakage may occur because the
shaft may loosen and fall.
Turn off the power at the
switchboard before beginning
the installation.
Fire or electrical shock can result
if the power is left on.
SAFETY INSTRUCTIONS
The user and installer must read the appropriate safety instructions before attempting to install
or operate the equipment.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
Warning, Caution Mandatory Action
Prohibitive Action
DANGER
Indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
Do not install the equipment where it
may get wet from rain or water splash.
Water in the equipment can result in fire,
electrical shock or equipment damage.
Be sure no water leaks in at the trans-
ducer installation site.
Water leakage can sink the vessel. Also
confirm that the transducer will not loosen
by ship's vibration. The installer of the
equipment is solely responsible for the
proper installation of the equipment.
FURUNO will assume no responsibility for
any damage associated with improper
installation.

ii
CAUTION
Turn off the POWER switch on the hull
unit before using the hand crank.
Bodily injury can result if the hand crank
rotates unexpectedly, because the raise/
lower motor may start up.
Observe the following compass safe
distances to prevent interference to a
magnetic compass:
Standard
compass Steering
compass
Processor
unit 0.4 m 0.3 m
Observing the following speed limits
when testing the equipment at sea trial:
Raising/lowering transducer: 16 kts max.
Transducer completely lowered: 18 kts max.
Exceeding above limits will damage the
equipment and void the warranty.
The zinc block near the transducer must
be replaced yeary.
The junction between the transducer and
main shaft may corrode, which can result
in loss of the transducer or water leakage
inside the ship. Replace the zinc block
yeary.
CAUTION
Attach protection earth securely
to the ship's body.
The protection earth is required
to the transceiver unit and DC-AC
inverter (option) to prevent
electrical shock.

1. MOUNTING
NOTICE
Be sure the power supply matches equipment voltage
rating.
Improper power supply will damage the equipment.
Locate the transducer where the effects of noise and
air bubbles are minimal.
Noise and air bubbles will affect performance.
When selecting a mounting location keep the
following points in mind:
Keep equipment out of direct sunlight.
Keep equipment away from air conditioner.
Provide sufficient ventilation.
Select locaion where vibration is minimal.
Locate the equipment away from magnets or equipment generating
magnetic fields.
Keep the transducer cable away from oil.
Oil can corrode the transducer cable.
Do not expose the transducer to hot water.
Hot water can damage the transducer.
Do not turn on the equipment with the transducer
exposed to air.
Exposing the transducer to air may damage it.

1.1 Hull Unit
1.1.1 Mounting location
Discussion and agreement are required with the dockyard and ship owner in deciding the
location for the hull unit. When deciding the location, take into account the following points:
• Select an area where propeller noise, cruising noise, bubbles and interference from
turbulence are minimal. Generally, the point at 1/3 to 1/2 of the ship’s length from the bow or
near the keel is the best. On-the-keel installation is advantageous for minimizing oil
consumption in comparison with off-the-keel. If the hull unit cannot be installed on the keel,
the center of the retraction tank should be within 1 meter of the keep to prevent a rolling
effect.
1/2 1/3 Within 1 m
Installation location for hull unit
• Select a place where interference from the transducers of other sounding equipment is
minimal. The hull unit should be at least 2.5 meters away from the transducers of other
sounding equipment.
• An obstacle in the fore direction not only causes a shadow zone but also aerated water,
resulting in poor sonar performance. Be sure to locate the transducer well away from any
obstacle in the fore direction.
• The space shown in the illustration below is required around the hull unit for wiring and
maintenance. If the transducer is to be operated in ambient temperature below 0°C, the sonar
compartment must be provided with a heater to keep the temperature above 0°C.

When the retraction tank is made locally, finish it so that
the welding bead does not protrude on the inner surface
of the tank. The tank guide will hit the bead, causing
motor born-out. The gap between the tank and tank guid
is 1 mm. Also when installing the tank, orient the welding
bead so it faces the port or starboard direction.

1.1.2 Installation of the retraction tank
The retraction tank is 1000 mm in length as supplied. Shorten the tank referring to the table
below so the transducer fully protrudes beyond the keel when it is lowered. Refer to the
installation procedure at the back of this manual for details.
