WARNING
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
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.
Do not open the cover
unless totally familiar with
electrical circuits and
service manual.
High voltage exists inside the
equipment, and a residual
charge remains in capacitors
several minutes after the
power is turned off. Improper
handling can result in electri-
cal shock.
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.
If a steel tank is installed on a wooden
or FRP vessel, take appropriate
measures to prevent electrolytic
corrosion.
Electrolytic corrosion can damage the
hull.
Be sure that the power supply is
compatible with the voltage rating of
the equipment.
Connection of an incorrect power supply
can cause fire or equipment damage. The
voltage rating of the equipment appears
on the label above the power connector.
CAUTION
Observe the following compass safe
distances:
Ground the equipment to
prevent electrical shock and
mutual interference.

3. MOUNTING THE EQUIPMENT
3.1 Mounting the Hull Unit and Receiver Unit
Location of hull unit
Decide the location of the hull unit through consultation with the dockyard and shipowner.
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 turbu-
lence are at a minimum. Generally, the point at 1/3 to 1/2 of the ship’s length from the bow
on or near the keel is optimum. On-the-keel installation is advantageous for minimizing oil
consumption in comparison with off-the-keel. If the hull unit can not be installed on the keel,
the center of the retraction tank should be within 600 mm of the keel to prevent a rolling
effect.
Figure 3-1 Hull unit mounting location
• 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 equipment 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 space shown in the figure on the next page is required around the hull unit for wiring and
maintenance.
• If the ambient temperature of the unit is below 0°C, provide the sonar compartment with a
heater to keep the temperature above 0°C.

Figure 3-2 Maintenance space, example sonar compartment

5
Shortening the retraction tank
The retraction tank is 1300 mm in length when supplied. Shorten the tank as necessary so that
the transducer is placed well below the keel when it is lowered. The following table provides
guidelines for shortening the tank. Refer also to the retraction tank installation drawing at the
back of this manual.

Same as left
Figure 3-3 Guidelines for shortening the retraction tank
Note 1: In the 800 mm type hull unit, more than 297 mm must be removed from the bottom so
that the transducer fully protrudes from the tank. If more than 382 mm is removed, the trans-
ducer cannot be retracted into the tank.
Note 2: In the 1200 mm type hull unit, the transducer will not fully protrude unless 97 mm is
removed from the bottom, and cannot be fully retracted if more than 382 mm is removed.
Note 3: In the 1600 mm type hull unit, the transducer cannot be fully retracted if more than 282
mm is removed.
Note4:When 382 mm (282 mm for 1600 mm type) is removed and “D” is minimum, the effect
of air foam is minimized because the transducer fully protrudes in water.

Remarks for installation of retraction tank
1. Make, if possible, the installation location a double bottom structure.
2. Install, if possible, the tank on the keel where the tank can be most firmly fixed.
3. Install the reinforcement ribs as near as possible to the top of the retraction tank, allowing
space for tightening of bolts and nuts.
Figure 3-4 How to install reinforcement ribs
4. When an attachment flange is used, install reinforcement ribs to the attachment flange.
Figure 3-5 Installing reinforcement ribs to the attachment flange
5. Add a doubling plate at the location where the retraction tank is welded to the hull bottom.
The size of the doubling plate is normally 1200 mm to 1300 mm in diameter so that it lies
across two bottom frames.

7
Installing hull unit on retraction tank
After welding the retraction tank and allowing sufficient time for cooling, install the hull unit as
follows:
1. Clean the hull unit flange, the O-ring and O-ring groove and coat them with a slight amount
of grease. Place the O-ring in position on the tank flange.
2. Lay the gasket (1) on the top of the tank flange.
3. Orient the hull unit so that the bow mark (arrow) on its flange points toward the ship’s bow.
Note that heading adjustment in the display unit is required if the bow mark does not face
the ship’s bow.
4. For the 1200 mm transducer travel type, 11 of the 24 bolt holes on the hull unit flange have
already been fitted with bolts. Insert the gasket (2) into the bolt holes of the tank flange to
which these 11 bolts are fitted. Note that it is difficult to fit them after the hull unit has been
placed on the tank.
5. Confirm that the O-ring and the gasket (1) are in position. Place the hull unit on the tank.
6. Coat every bolt, washer and nut with slight amount of grease to ease removal. Fit the insu-
lation gasket (2) into the bolt holes of both the tank and hull unit flanges. Fasten the hull unit
to the retraction tank with gasket (2), flat washers, spring washers and hex bolts. (Insulation
gasket (2) and gasket (2) are used on the 1200 mm transducer travel type only.)
7. Reinforce the hull unit against vibration by extending stays to the ship’s hull from the two
eye bolts at the top of the hull unit, referring to figure at the top of the next page.

Installing stays (anti-vibration
measure)
Install stays from the top of the hull unit to
the ship’s hull. The stays should be angle
iron with a size of 75 x 75 x 9 mm or more
and at least two pieces should be used; one
each to ship’s bow and stern directions. In-
stall if possible, two more stays in ship’s
transverse direction.
Do not install the stays as shown below. Vibration-resistance effect is reduced since vibration is
applied to the stays as rotation force. Install them horizontally.
Figure 3-8 Proper and wrong installation of stay
Fastening receiver unit to hull unit
Fasten the receiver unit to the left side of the hull unit
as shown at right.
A transducer cable protection cover has been fitted
where the receiver unit is to be fastened to the hull unit.
Remove it when mounting the receiver unit.

3.2 Mounting the Display Unit/Sub-display Unit
The display unit/sub-display unit is designed for tabletop mounting. When selecting as mount-
ing location consider the following conditions:
• Place where operating personnel are able to control the unit easily while observing the fish-
ing ground or the area surrounding the vessel.
• Place at least 1 m away from a magnetic compass and components which have a magnet
(radarmagnetron,loudspeaker, high powertransformer, etc.)
• Place not exposed to direct sunlight, water splashes or hot
air.
• Place where maintenance and ventilation clearance shown
in the outline drawings is ensured.
• Place where the CRT face is within ±45°from vertical.
Mounting the display unit/sub-display unit
1. Remove the mounting base by unscrewing the two bolts at
the front bottom.
2. Fix the mounting base to the table with four M10 bolts, flat
washers, spring washers and nuts. It is recommended that a
rubber mat be placed under the mounting base to absorb
vibration.
3. Fasten the unit to the mounting base with two bolts. When
the space around the unit is limited, make wirings to the
display unit first and then fasten the unit.
Note: For the CSH-24, remove eye bolts at the top of the dis-
play unit and set cosmetic screws (supplied with installation
materials) to eye bolt holes. Figure 3-10 Mounting the display unit,
sub-display unit

3.3 Mounting the Transmitter Unit
The transmitter unit can be mounted with or without mounting legs. For use without mounting
legs remove them and use inside mounting holes.
The transmitter unit should be reinforced against vibration by stays extending from the eyebolts
on the top of the unit.
Attach stay to
this eye bolt.
Mounting leg for
outside leg mounting
For mounting without legs
,
remove legs and use inside
holes for mounting.
Figure 3-11 Transmitter unit
3.4 Mounting the Interface Unit
Since the interface unit connects with several navigation and fishing equipment, determine the
installation site with the wirings to them taken into account. Furthermore, the unit incorporates
a data selector and self-check switch, so select a place where they can be easily operated.
3.5 Mounting the FNZ Joint Box
The FNZ joint box is used for interchanging both TX trigger and sonde marker pulses from the
echo sounder and the net sonde, therefore it should be installed as close as possible to the net-
sonde indicator.
