SAFETY INSTRUCTIONS
WARNING
Indicates a condition that can cause death or serious
injury if not avoided.
CAUTION
Indicates a condition that can cause minor or moderate
injury if not avoided.
Warning, Caution Mandatory Action
Prohibitive Action
Read these safety instructions before you operate the equipment.
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.

1. 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 transducer.
• 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 account the follow-
ing 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.
• Select a place where interference from the transducers of other sounding equip-
ment is minimal. The hull unit should be at least 2.5 meters away from the transduc-
ers 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.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating or
plastic parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.

1. MOUNTING
1-2
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, watertighness) first, followed by ease of mainte-
nance and inspection.
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 as described
in the paragraph "Assembling and mounting of hull
unit" on page 1-3.
Note 1: Do not shorten the 1 meter retraction tank.
Shortening it may also necessitate shortening of
the top part of the main shaft, thereby destroying
the watertight construction of the 1.17 meter shaft.
Note 2: When the retraction tank is constructed lo-
cally, 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. Al-
so, do not position the welding bead in the ship’s
fore-aft line.
Note 3: Use of other manufacturer’s tank is permit-
ted. However, the dimensions should be the same
as those in the transducer tank outline drawing.
Mounting of transducer tank
Install the transducer tank referring to the hull unit out-
line drawings at the back of this manual.
Note: Locate one of the bolt holes 10° to port to mini-
mize mechanical shock at the raise/lower block during
pitching and rolling.
