The steel conduit must preferably be straight. Start the conduit immediately above the
transducer, and terminate it well above the water line. If you must introduce bends on
the steel conduit, take the minimum cable bending radius into consideration.
2 Manufacture the steel conduit according to the relevant production standards.
3 Mount the steel conduit.
Secure the steel conduit to decks and/or bulkheads with welds. Observe relevant
requirements and guidelines from the classification society, and make sure that the
conduit is properly supported, strong and watertight.
Note
The quality of the welding is critical to the safety of the vessel. Welding must only be
done by a certified welder.
4 If relevant, allow the maritime authority and/or classification society to inspect and
approve the design and the installation of the steel conduit.

Unpacking the transducer from its transport
crate
Prior to installation, the transducer must be unpacked from its box, and placed under the
mounting location.
Context
A transducer must always be handled as a delicate instrument. Incorrect actions may damage
the transducer beyond repair. Observe these transducer handling rules:
• Do not activate the transducer when it is out of the water.
• Do not handle the transducer roughly and avoid impacts.
•
Do not
expose the transducer to direct sunlight or excessive heat.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer face.
•
Do not
damage the outer protective skin of the transducer face.
