WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Be sure no water leaks in at the transdu-
cer 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.
WARNING
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 damage to the equipment.
The voltage rating of the equipment appears
on the label above the power connector.
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 damage to the
equipment.
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 tank doesn't strike
an object.
The tank or hull may be damaged if the
tank strikes an object.

WORKING WITH THE SONAROIL
Precautions
Keep oil away from eyes. Wear protective
gloves when working with the oil. The oil
can cause inflammation of the eyes.
Do not touch the oil. Wear protective
gloves when working with the oil. The oil
can cause inflammation of the skin.
Do not ingest the oil. Diarrhea or vomiting
can result.
Keep the oil out of reach of children.
Emergency
If the oil enters eyes, flush with clean
water about 15 min. Consult a physician.
If the oil contacts skin, wash within soap
and water.
If the oil is ingested, see a physician
immediately.
Disposal of oil and its container
Dispose of oil and its container in
accordance with local regulations.
For further details, contact place of
purchase.
Storage
Seal container to keep out foreign
material. Store in dark place.
CAUTION
Install the monitor unit MU-100C out of
direct sunlight.
It is difficult to see the display in direct
sunlight.
Keep hands away from the raise/lower
shaft of the hull unit when it is working.
Injury to hands may result if they become
caught in the shaft.
Do not exceed 20 knots when operating
the equipment and do not exceed 15
knots when raising or lowering the
transducer.
The transducer shaft may become
damaged.
The hull unit is designed to withstand ship's
speed of 20 knots. For vessel with greater
speed, reinforce the hull unit.
The transducer tank should be mounted at
the place above the waterline. If this is
impossible, make safety provisions (ex.
construction of watertight compartment).
If there is a possibibility of vibration at the
soundome in high-speed cruising, which
creates prssure inside the tank, discuss the
problem with shipyard and hull manufacturer.

1.3 Transceiver Unit
1.3.1 General mounting considerations
• The mounting location should be well ventilated and dry.
• The unit can be mounted on a bulkhead or the deck.
• The maximum cable length between the transceiver unit and the raise/lower
drive unit is 50 m.
• The maximum cable length between the transceiver unit and the monitor
(interface) unit is 10 m.
• Keep the transceiver unit out of splash.
1.3.2 Mounting method
Fasten the transceiver unit with four self-tapping screws (5X20, local supplied).
For bulkhead mounting, do as follows:
1. Tighten upper self-tapping screws so there is 5 mm clearance between
bottom of screw head and bulkhead.
2. Hook the transceiver unit on the upper screws.
3. Tighten the upper screws followed by the lower screws.

1.4 Hull Unit
1.4.1 General mounting considerations
• Noise and air bubbles will affect performance.
• Do not turn on the equipment with the transducer exposed to air. Exposing the
transducer to air may damage it.
1.4.2 Installation position considerations
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 keel to prevent a rolling effect.
1/2 1/3 Within 1 meter
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.
Mounting method
A typical mounting method is shown in the outline drawing at the back of this
manual. Consult ship’s owner, dockyard and user to determine appropriate
mounting method. Pay attention to safety (strength, watertightness) first,
followed by ease of maintenance and inspection.

Welding bead
Welding bead
1.4.3 Transducer tank
Tank length
Shorten the transducer tank so the transducer is lowered into water as deep as
possible. Pay particular attention to the tank length Lt. Determine the length of
the main shaft.
• Length of main shaft = Lt + 200 mm (for 400
stroke)
• Length of main shaft = Lt + 50 mm (for 250
stroke)
Note: When the retraction tank is constructed
locally, finish it so that welding beads do
not protrude on the inner surface of the
tank. The tank guide will hit the bead,
burning out the raise/lower motor. Also, do
not position the welding bead in the ship’s
fore-aft line.
For small FRP ship
The retraction tank should be mounted in
parallel with the ship’s draft. For a small ship, however, the hull has 2 degrees of
tilt rising toward the bow. This creates high water pressure in the tank because
of the resistance at the rear of the tank well. To solve this problem, attach a fin to
the hull at the location shown in the figure below.
Retraction tank

Bottom of ship
This fin creates a smooth stream in the retraction dome. Fin specifications:

Mounting of transducer tank
Install the transducer tank referring to the hull unit outline drawings at the back of
this manual.
Note 1: When making a retraction tank locally, the inside diameter of the
retraction tank should be φ190±0.5 as shown in the outline at the back of this
manual. If larger, the hull unit may be damaged.
Note 2: Locate the retraction tank so that the center of any two bolt holes is
facing the ship’s bow.
