SAFETY INSTRUCTIONS
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.
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.
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.

WORKING WITH THE SONAR OIL
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 with 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 accord-
ance with local regulations. For further
details, contact place of purchase.
Storage
Seal container to keep out foreign
material. Store in dark place.

MOUNTING
1.1 Hull Unit
General mounting considerations
• Noise and air bubbles will affect performance.
• Keep the transducer away from oil. Oil can corrode the cable.
• Do not expose the transducer to hot water. Hot water can damage the trans-
ducer.
• Do not turn on the equipment with the transducer exposed to air. Exposing the
transducer to air may damage it.
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 ac-
count 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 m
Figure 1-1 Installation location for hull unit
• Selecta placewhere interferencefrom thetransducers ofother soundingequip-
ment 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 aer-
ated water, resulting in poor sonar performance. Be sure to locate the trans-
ducer well away from any obstacle in the fore direction.

1-2
Mounting method
A typical mounting method is shown in the outline drawing at the back of this
manual.Consultship’sowner,dockyardanduser todetermineappropriate mount-
ing method. Pay attention to safety (strength, watertighness) first, followed by
ease of maintenance and inspection.
Tank length
Shorten the transducer tank so the trans-
ducer is lowered into water as deep as pos-
sible.
Pay particular attention to the tank length Lt.
Determine the length of the main shaft as
describedin theparagraph“Assembling and
mounting of hull unit.”
Note 1: Do not shorten the 1 meter retrac-
tiontank.Shortening it mayalso necessitate
shortening of the top part of the main shaft,
thereby destroying the watertight construc-
tion of the 1.17 meter shaft.
Note 2: When the retraction tank is con-
structedlocally, finishitso thatweldingbeads
do not protrude on the inner surface of the
tank. The tank guide will hit the bead, burn-
ing out the raise/lower motor. Also, do not
position the welding bead in the ship’s fore-
aft line.
Note 3: Use of other manufacturer’s tank is
permitted. However, the dimensions should
be the same as those in the transducer tank
outline drawing.
Mounting of transducer tank
Installthe transducer tankreferring to thehull
unit outline drawings at the back of this
manual.
Note: Locate one of the bolt holes 10°to port
to minimize mechanical shock at the raise/
lower block during pitching and rolling.

CAUTION
WORKING WITH THE SONAR OIL
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 minutes. Consult a physician.
• If the oil contacts skin, wash with 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 accord-
ance with local regulations. For further
details, contact place of purchase.
Storage
Seal container to keep out foreign
material. Store in dark place.

3. Shorten the main shaft by the length of Lt + 110 mm, where Lt is the length of
the retraction tank. When the retraction tank length is 1 meter do not shorten
the 1.17 meter main shaft.

Checking manual raise/lower of transducer with hand
crank
Perform this check after all wiring has been completed. Ship’s mains power must
applied to the hull unit, otherwise the magnetic brake of the raise/lower motor
activates, disabling the manual raise/lower gears.
1. Turn off the breaker on the hull unit.
2. Detach the brake-off switch cover.
3. Set hand crank to the screw shaft gear and turn it while pressing the brake-off
switch.
4. The transducer should rise/lower smoothly with even force in upper to lower
limits. If not, the centers of the main body flange and the retraction tank are
not aligned.Adjust the hull mounting position if necessary.
