equipment is solely responsible for the
proper installation of the equipment.
FURUNO will assume no responsibility for
any damage associated with improper
installation.
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 an object strikes the tank.
The tank or hull may be damaged if the
tank strikes an object.
Turn off power at the switchboard before
starting the installation.
Electrical shock or fire can result if the
the power is left on.
Make sure the drive shaft brake and

1. HOW TO INSTALL THE SYSTEM
1.1 Hull Unit (FSV-253/FSV-254)
Note 1: The raise/lower control box on the hull unit contains a motion sensor. Handle
the hull unit carefully.
Note 2: Handle the transducer carefully. Rough handling can damage its sensitive
components.
1.1.1 Installation considerations
Decide the location of the hull unit through consultation with the dockyard and ship
owner. When deciding the location, the following points should be taken into account.
• Select an area where propeller noise, cruising noise, air bubbles and interference
from turbulence are at a minimum. Generally, the point at 1/3 to 1/2 of the ship's
length from the bow on the keel is optimum. On-the-keel installation is
advantageous for minimizing oil consumption. For large ships with deep draft, the hull
unit can be installed at the bow, along the keel line. (See figure below for reference).
• For installations where there are other transducer tanks along the keel, install the hull
unit a minimum distance of three times the internal diameter of the tank directly in
front (bow direction) of the hull unit. Failure to install the hull unit with sufficient
spacing can result in excessive vibrations caused by turbulence, which can damage
the hull unit. (See figure above for reference).
• Select a place where the hull bottom is flat and the draft is sufficiently deep.
Normally, the transducer should protrude at least 500 mm beyond the keel to
minimize the effect of air foam and bubbles.
• Select a place where interference from other transducers is minimal. The hull unit
should be at least 2.5 m away from the transducers of other equipment.
• No obstacle should be in the fore direction since it causes a shadow zone and
aerated water, resulting in poor sonar performance.
• The physical distance between the hull unit and the transceiver unit should be no
more than 5 m.
• In the case of a bilge keel, select a location as far from the bilge as possible, but no
more than 5 m from the transceiver unit.
• Select a location away from indents and protrusions on the hull, especially indents,
as they can create noise interference and cause poor sonar performance.
• The space shown in the figure on the next page is required around the hull unit for
wiring and maintenance.
• If the ambient temperature around the unit will be below 0°C, provide the sonar
compartment with a heater to keep the temperature above 0°C.

Note 1: After you install the hull unit,
make sure you install anti-vibration stays.
(See "How to install the stays (anti-vibra-
tion and anti-shock
measures)" on page 1-6.)
Note 2: Prepare a secure and firm safety
fence for the hull unit, to prevent acciden-
tal injury from the moving hull unit. The
safety fence should be easily removable
for maintenance and allow room for the
connected cables to swing freely with
pitch, roll and heave. The raise/lower con-
trol unit and emergency buttom should be
installed and operatable from outside the
safety fence.
1.1.2 How to shorten the retraction tank
The following table provides cutting guidelines for shortening the tank. Refer also to
the retraction tank installation drawing at the back of this manual.
Note 1: The default length for the retraction
tank is 1300 mm. By removing only 88 mm
fromtheretractiontank,youcaneliminatethe
need for limit switch adjustment.
Note 2: For both 1200 mm and1600 mm trav-
el hull units, the transducer will not fully re-
tract unless the tank is shortened by more
than 90 mm.

Guidelines for installation of the retraction tank
• If the keel plate on the inside of the hull is not adequate for installing the retraction
tank, install a secondary keel plate.
• Install the retraction tank where the keel plate and hull frame intersect.
• If there is no suitable location where the hull frame and keel intersect, install suitable
“T” shaped reinforcement ribs, then weld the base of the frame to the reinforcement
ribs and the sides of the reinforcement ribs to the hull walls or other nearby
reinforcement ribs. The reinforcement ribs should be secured in the fore, aft, port
and starboard directions.
• Install the reinforcement ribs as near as possible to the top of the retraction tank,
allowing 150 to 200 mm space for tightening of nuts and bolts.
• Fit a doubling plate (a plate added to another to give extra strength or stiffness) to
the location where the retraction tank is welded to the hull bottom. While it is
recommended that both sides attach to the hull, consult with the installer
regarding length and diameter.
• The thickness for doubling plates and reinforcement ribs is 12 mm minimum.

1.1.3 How to install the hull unit on the retraction tank
Weld the retraction tank and allow sufficient time for cooling. Install the hull unit as
follows:
Prepare the materials and tools as shown below.
Use the figure on the following page for reference when installing the hull unit on the
retraction tank.
1. Clean the flange and O-ring groove of the retraction tank (welded to hull) with ethyl
alcohol moistened waste cloths.
2. Apply lithium grease to the O-ring and O-ring groove. Place the O-ring in its
groove on the tank flange.
3. Orient the hull unit so that the bow mark (inscribed) on its flange points toward the
ship's bow. Note that heading adjustment is required if the bow mark is not facing
the ship's bow. (See "How to Adjust the Heading" on page 3-9.)
4. Confirm the points as listed below, then place the hull unit on the tank.
• Clean the flange platform.
• Wipe the under-face of the hull unit with clean waste cloths.
• Keep the O-ring in its groove.
5. Apply a slight amount of lithium grease to the threads of the bolts to prevent
scorching. Insert the bolts with washers from the retraction tank flange, and then
put the flat washers and spring washers in this order from above. Fasten bolts with
nuts.

How to install the stays (anti-vibration and anti-shock measures)
This measure must be done after installing the hull unit to prevent damage from
vibration or impact shock to the transducer. Stays should be as sturdy as possible
(75759 mm minimum recommended). Install a minimum of two stays, one in the aft
direction, one in the fore direction. Where possible install two more stays (one in the
port and one in the starboard direction), making a total of four stays. Where the hull
units is installed off center from the bow-stern line, install the stays at right angles with
the bow mark on the hull unit.
Where horizontal installation of the stays is
not possible, install the stays in a diagonal
manner to reduce vibration in the hull unit. In-
stall the upper stays (attached to the top of the
hull unit) in opposing directions (one facing
fore, one facing aft), then attach the stays to
ceiling beams. This reduces axial movement.
The side stays should be installed and at-
tached to the hull framework.
Shackle holes
When transporting the hull unit in a horizontal manner, use
the shackle holes shown in the figure to the right. Attach
shackles to the holes, then use block and tackle or chain,
attached to the shackles, to move the hull unit.
Note: Once the hull unit is set in place, remove the shack-
les and ropes. Also, when removing the metal fittings on
the cables wrapped around the hull unit, remove the ca-
bles.

1.2.1 Installation considerations
When selecting a mounting location, keep the following points in mind:
• Mount the unit upright (connectors facing downwards), or horizontal.
• Locate the unit out of direct sunlight and away from heat sources because of heat
that can build up inside the unit.
The maximum normal operating temperature for this equipment is +45°C.
• Install the unit away from areas subject to water splash or rain.
• Be sure the mounting location is strong enough to support the weight of the unit
under the continued vibration which is normally experienced on the ship.
If necessary reinforce the mounting location.
• Determine the mounting location considering the length of these cables:
• Signal cable from the transceiver unit.
• control cable from the control unit.
• Leave sufficient space on the sides of the unit to facilitate maintenance. Also, leave
a foot or so of “service loop” in cables for servicing or easy removal of connectors.
See the outline drawing at the back of this manual for recommended maintenance
space.
• Follow the compass safe distances in the "SAFETY INSTRUCTIONS" on page i to
prevent interference to a magnetic compass.

1.4 Transceiver Unit (FSV-251)
Select a mounting location considering that the effective length of the cable between
the transceiver unit and the hull unit is 10 m (standard).
The transceiver unit should be fixed to a mounting base (shipyard supply) whose
dimensions are as shown in the outline drawing at the back of this manual.
Reinforce the transceiver unit against vibration by following the procedure below.
1. Attach the anti-vibration device (2 pcs.) to the
mounting base using M12 bolts and nuts (4 pcs, lo-
cal supply). Insert the bolts from the top of the fix-
ing plate.
2. Place the transceiver feet on the anti-vibration devices.
Note: Keep the transceiver unit level with horizontal line when the feet are placed
on the anti-vibration devices. If the unit is placed on the anti-vibration device cor-
rectly, the stoppers (4 locations) should be separated by a gap of approx. 10 mm.
3. Fix the transceiver unit to the anti-vi-
bration devices with M12x50 hex
bolts, spring washers, plain washers
and 2 x nuts (supplied). Insert the
bolts from the bottom of the fixing
plate.
