Unpacking mechanical units
Prior to installation or use, mechanical units 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
Mechanical and electromechanical units may be heavy.
Hull units provided for sonar systems are provided with the transducer already mounted.
Note
The transducer is a delicate item. Make sure that it is not exposed to physical damage during the storage, unpacking, lifting and installation of the hull unit. The transducer is protected with a box shaped foam. Do not remove this protection until the final stages of the hull unit installation.
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.
Procedure
1 Obtain the necessary lifting equipment, and make sure that the equipment is certified for the weight.
2 Lift the unit 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 Remove any packing material that may be inside the unit.
6 Collect and keep the relevant user manuals and/or documents provided with the unit.
