Visual inspection of the hull unit
A visual inspection of the hull unit is required to make sure that the unit has not been
physically damaged during the installation. It is also important to check that the unit has
been installed correctly.
Prerequisites
The MF90 system hardware units are installed as specified in this manual. The MF90 system
is turned off. You need the following equipment:
• Multimeter
Context
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.
Procedure
1 Make sure that the hull unit is installed in the correct location, and that it is suitably
oriented for easy maintenance and replacement of parts.
2 Make sure that the unit is not physically damaged, and that the surfaces and paint-work
are clean without dents or scratches.
The physical handling during the installation may have caused some minor scratches
to the surfaces or paint-work. This can be accepted. However, if rough handling has
caused serious damage, this must be recorded with a written statement and necessary
photos, so that corrective actions can be made.
3 Make sure that the unit has been identified with the relevant product label(s), and that
one label includes the part and serial numbers.
4 Make sure that the physical installation of the unit has been completed.
a Make sure that the welds and brackets used to support the hull unit are substantial
enough to hold the unit securely under all operating conditions.
b Make sure that the compartment ("sonar room") in which the hull unit is mounted
is clean and dry.
