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

3. MOUNTING THE EQUIPMENT
3.1 Mounting the Hull Unit and Receiver Unit
Location of hull unit
Determine the mounting location through consultation with the shipyard and shipowner. When
deciding the location, consider the following points:
• Select an area where propeller noise, cruising noise, air bubbles and interference from turbu-
lence are minimal. 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 con-
sumption 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.
Within 600 mm
1/3 1/2
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. Locate the hull unit 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.
• Secure sufficient space for wiring and maintenance. Refer to the hull unit outline drawing
for recommended wiring and maintenance space.
• If the ambient temperature of the hull unit is below 0°C, provide the sonar compartment with
a heater to keep the temperature above 0°C.

Shortening the retraction tank
The retraction tank is 900 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 guide-
lines for shortening the tank. Refer also to the retraction tank installation drawing at the back of
this manual.

Remarks on installation of retraction tank
• If possible, the installation location should be of double bottom structure.
• If possible, install the tank on the keel, where the tank can be most firmly fixed.
• Install the reinforcement rib as near as possible to the top of the retraction tank, allowing
space for tightening bolts and nuts.

e
250–300 mm
Figure 3-5 Attachment flange
• Add a doubling plate where the retraction tank is welded to the hull bottom. The size of the
doubling plate is normally 1200 to 1300 mm in diameter so it lies across two bottom frames.

3-5
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 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 arrow on its flange points toward the ship’s bow.
4. 7 of the 16 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 seven 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.
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 x75 x9 mm or more and at least two pieces should be used; one each to ship’s bow
and stern directions. If possible, install two more stays in ship’s transverse direction.

3.2 Mounting the Display Unit and Sub-Display Unit (option)
The display unit and sub-display unit are designed for tabletop mounting. When selecting a
mounting 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 equipment which have a magnet (radar
magnetron, loudspeaker, high power transformer, etc.).
• Place not exposed to direct sunlight, water splashes or hot air.
• Place where maintenance and ventilation clearance shown in the outline drawings is en-
sured.
• 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 by using 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.

3.4 Mounting the Power Unit
The power unit can be installed in any dry, well-ventilated place.
3.5 Mounting the Interface Unit
The interface unit connects with several navigation and fishing equipment, so determine the
installation site with the wiring to them taken into account. Furthermore, the unit incorporates
a data selector and self-check switch, therefore select a place where they can be easily operated.
3.6 Mounting the FNZ Joint Box
The FNZ joint box interchanges both Tx trigger and sounder marker pulses from the echo
sounder and the net sonde. Therefore, install it as close as possible to the net-sonde indicator.

Figure 4-2a Crimping tool, contact pin, pin extractor
How to use the crimping tool
1. Strip the vinyl sheath of the wire to expose the core by 3.2
mm to 4 mm.
2. Hold the crimping tool horizontally and insert the contact
pin with its slit facing downward into the crimp hole on the
crimping tool.
3. Insert the wire onto the contact pin and squeeze the handle
until the ratchet releases. (Place the wire deep enough into
the contact pin so that its end comes in contact with the
stopperplateof the crimping tool.)Withcrimping completed,
pull the wire while holding the contact pin to make sure that
the pin is fastened tightly.
How to use the pin extractor
If a contact pin is inserted into an incorrect hole on the
connector body, remove it with the pin extractor.
1. Push the pin extractor into the pin hole from the side
opposite to the pin inserting side.
2. Push in the head of the pin extractor. The retaining
spring comes free and the contact pin can be removed.
