SAFETYINSTRUCTIONS
Do not work inside the
equipment unless totally
familiar with electrical
circuits.
Hazardous voltage which can
shock exists inside the equip-
ment.
Turn off the power at the
mains switchboard before
beginning the installation.
Post a sign near the switch
to indicate it should not be
turned on while the equip-
ment is being installed.
Fire or electrical shock can
result if the power is left on or
is applied while the equip-
ment is being installed.
WARNING
Install the display unit and transceiver
unit where they will not be exposed to
water splash or rain.
Fire or electrical shock can result if water
leaks inside those units.
Ensure no water leaks through the
mounting location for the transducer.
The ship may sink if water leaks through the
mounting location. Check the location care-
fully at installation.
The retraction tank should be con-
structed of the specified material and
installed in accordance with the pro-
cedures set forth in this manual. Use of
other material or procedure is the
responsibility of the shipyard. In any
case the tank should be installed so
the hull will not be seriously damaged
in the event the tank is struck by an
object.
CAUTION
Use the proper fuse.
Use of a wrong fuse can result in fire or
permanent equipment damage.
Replace zinc block near the transducer
yearly.
If not replaced corrosion between trans-
ducer and main shaft may result.
Do not exceed speed noted in the speci-
fications when operating the equipment
or lowering or raising the transducer.
The transducer may become damaged.
Ground the equipment to
prevent mutual interference.
POSSIBILITY OF INJURY
1. If breaker (hull unit) trips do the
following:
1) Turn off power swich on hull unit.
2) Wait 60 sec after breaker has tripped.
3) Press breaker.
2. Turn off hull unit before using hand
crank.
WARNING
POSSIBILITY OF WATER LEAKAGE
To prevent loss of main shaft of the hull
unit and water leakage tighten bolts fixing
shaft retainer for torque of 2000-2500 N•
cm and tighten fastening band for torque
600-800 N•cm.

MOUNTING
1.1 General Mounting and Handling Considerations
• Be sure the power supply matches equipment voltage rating. Improper power supply will
damage the equipment.
• Locate the transducer where the affects of noise and air bubbles are minimal. Noise and air
bubbles will affect performance.
• When selecting a mounting location keep the following points in mind:
• Keep equipment out of direct sunlight.
• Keep equipment away from air conditioner.
• The useable temperature range of the display unit is 0°–50°C.
• Provide sufficient ventilation.
• Select location where vibration is minimal.
• Locate the equipment away from magnets and magnetic materials.
• 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.
• Magnetic compass performance will be affected if it is placed too close the display unit.
Observe the compass safe distances shown below to prevent deviation of a magnetic com-
pass.
Standard compass: 1.3 m
Steering compass: 1.0 m

1.2 Mounting the Hull Unit
Location
Discussion and agreement are required with the dockyard and ship owner in deciding the loca-
tion 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 turbu-
lence 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 keep to prevent a rolling effect.
1/2 1/3 Within 1 m
Figure 1-1 Installation location for hull unit
• Select a place where interference from the transducers of other sounding equipment is mini-
mal.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.
• The following space is required around the hull unit for wiring and maintenance. If the
transducer is to be operated in ambient temperature below 0°C, the sonar compartment must
be provided with a heater to keep the temperature above 0°C.

Installation of the retraction tank
The retraction tank is 1000 mm in length as supplied. Shorten the tank referring to the table
below so the transducer fully protrudes beyond the keel when it is lowered. Refer to pages D-1
to D-6 for details.
