Unpacking transducers
Prior to installation or use, transducers, sonar heads and hydrophones must be unpacked
from their transport boxes. It is important that this unpacking is done without inflicting
damage to the equipment.
Prerequisites
Observe the procedure for unpacking of standard parts and units.
Context
Transducers may be supplied mounted to a hull unit (if any), or packed separately. Sonar
heads and hydrophones are normally packed and shipped in separate boxes. Boxes are
identified by the order number and the serial number of the unit inside.
Note
Once a transducer, sonar head or hydrophone is unpacked, make sure that the body and
the cabling are not exposed to any mechanical stress. Protect the transducer face with a
padded cover plate to prevent damage.
Transducers may be heavy.
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 lift the transducer by the cable.
•
Do not
step on the transducer cable.
• 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.
Procedure
1 Obtain the necessary lifting equipment, and make sure that the equipment is
certified for the weight.
2 Lift the transducer, sonar head or hydrophone out of the transportation box.
3 Place it in a stable position on the floor/work bench.
4 Inspect the unit for visual damage.
5 Make sure that the relevant protection is kept in place until the final stages of the
installation.
6 Collect and keep the relevant user manuals and/or documents provided with the unit.
