Context
1 0° transducer mark
2 Forward (label)
3 Mechanical support brackets (Due to its
height and weight, the hull unit gantry
must be secured to the bulkhead by means
of mechanical support brackets.)
4 Strengthening knee plates (stiffereners)
(The location of strengthening plates
(stiffeners) on the installation trunk is
indicated. Minimum four strengthening
plates must be used.)
5 Forward
The hull unit is fitted with a label that indicates
the forward (bow) direction. Mount the hull
unit with the arrow on the mounting flange pointing forward. This places the 0° transducer
mark at an angle of approximately 120 degrees on the port side relative to the bow.
The hull unit, transducer and transducer cable must be handled with care.
Note
• The transducer is protected with a thick layer of foam to prevent damage during transport
and hull unit installation. This protection must remain attached while the hull unit is
being manoeuvred into the sonar room.
• The transducer is covered with a thick red or black protective coating made of a special
plastic type. The protective coating is a vital part of the transducer. It is very important
that neither this coating nor the internal parts of the transducer are damaged during the
handling, installation or cleaning. Any holes and/or scratches in the transducer surface
will allow water to penetrate the transducer. If a leak occurs, the transducer must be
replaced.
• The top mating surface of the installation trunk must be protected with a blind flange
or wooden cover at all times until the hull unit is installed. It is very important that
this surface is clean and undamaged. It must be watertight after the hull unit has been
installed.
• The Motor Control Unit must never be physically dismounted from the hull unit gantry.
