1. HOW TO INSTALL THE SYSTEM
1.1 Hull Unit
Note 1: The control box on the hull unit contains a inertial measurement unit. Handle
the hull unit carefully.
Note 2: Handle the transducer carefully. Rough handling will damage its sensitive
components.
1.1.1 Installation considerations
Decide the location of the hull unit through consultation with the dockyard and ship
owner. When deciding the location, the following points should be taken into account.
• Select an area where propeller noise, cruising noise, air bubbles and interference
from turbulence are at a minimum. 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 ad-
vantageous for minimizing oil consumption 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 from the keel to prevent a rolling effect. For large ship with deep
draft, the hull unit can be installed at the bow.
• Select a place where the hull bottom is flat and the draft is sufficiently deep. Normal-
ly, 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 transducers is minimal. The hull unit
should be 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 aer-
ated water, resulting in poor sonar performance.
• The physical distance between the hull unit and the transceiver unit should be no
more than 5 m.
• The space shown in the figure on the next page is required around the hull unit for
wiring and maintenance.

• If the ambient temperature around the unit will be below 0°C, provide the sonar
compartment with a heater to keep the temperature above 0°C.
Note: After you mount the hull unit, be sure to install anti-vibration stays, referring to
page 1-5.

1.1.2 Guideline for how to shorten the retraction tank
Shorten the tank as necessary so that the transducer positions well below the keel
when it is fully lowered. The following table provides guidelines for shortening the tank.
Refer also to the retraction tank installation drawing at the back of this manual.
Note 1: Adjust the position for the TX limit switch, according the retraction tank length.
For how to adjust the position for the TX limit switch, see section 1.1.4.
Note 2: When maximum length is removed and "D" is minimum, the effect of air foam
is minimized because the transducer fully protrudes in water.
Guidelines for installation of the retraction tank
• If the keel plate on the inside of the hull is not adequate for installing the retraction
tank, install a secondary keel plate.
• Install the retraction tank where the keel plate and hull frame intersect.
• If there is no suitable location where the hull frame and keel intersect, install suitable
“T” shaped reinforcement ribs, then weld the base of the frame to the reinforcement
ribs and the sides of the reinforcement ribs to the hull walls or other nearby
reinforcement ribs. The reinforcement ribs should be secured in the fore, aft, port
and starboard directions.
• Install the reinforcement ribs as near as possible to the top of the retraction tank,
allowing 150 to 200 mm space for tightening of nuts and bolts.
• Fit a doubling plate (a plate added to another to give extra strength or stiffness) to
the location where the retraction tank is welded to the hull bottom. While it is
recommended that both sides attach to the hull, consult with the installer
regarding length and diameter.

1.1.3 How to install the hull unit on the retraction tank
Weld the retraction tank and allow sufficient time for cooling. Install the hull unit as fol-
lows:
Prepare the materials and tools as shown below.
1. Clean the flange and O-ring groove of the retraction tank (welded to hull). Use
waste cloths moistened with ethyl alcohol.
2. Coat the O-ring and O-ring groove with lithium grease, then place the O-ring in its
groove on the tank flange.
3. Orient the hull unit so that the bow mark (inscribed on its flange) points toward the
ship's bow.
Note: If the bow mark on the hull unit flange is not facing the ship's bow, rotate the
transducer so that the bow mark on the transducer points toward the ship’s bow
(see section 3.9).
4. Confirm the following points, then place the hull unit on the retraction tank.
• Clean the flange platform.
• Wipe the undersurface of the hull unit flange with clean waste cloths.
• Keep O-ring in its groove.

How to install the stays (anti-vibration and anti-shock measures)
This measure must be done after installing the hull unit to prevent damage from vibra-
tion or impact shock to the transducer. Stays should be as sturdy as possible
(75×75×9 mm minimum recommended). Install a minimum of two stays, one in the aft
direction, one in the fore direction. Where possible install two more stays (one in the
port and one in the starboard direction), making a total of four stays. Where the hull
unit is installed off center from the bow-stern line, install the stays at right angles with
the bow mark on the hull unit.
Where horizontal installation of the stays is not possible, install the stays in a diagonal
manner to reduce vibration in the hull unit.

1.1.4 How to adjust the TX limit switch position
Adjust the TX limit switch position so that the switch is turned on where the transmit-
ting face of the transducer is projected from the hull unit.
Distance to the transmitting position (A) can be selected from 450 mm, 425 mm, 400
mm, 375 mm or 350 mm. The distance to the transmitting position can be calculated
with the following formula. Select the value closest to the calculation.
• A = T- 450 mm
For example, when the tank length (T) is 820 mm, the calculated value is “ A = 820 -
450 = 370 mm”. Therefore, adjust the TX limit switch so that the distance to the trans-
mitting position is 375 mm.
Note: The transducer can transmit when the transducer is projected 300 mm from the
retraction tank.
