• A mild synthetic detergent and a plastic brush
• A piece of wood or plastic without sharp corners
• Citric acid (<50%) (only if required)
Context
During normal use, the transducer is subjected to biological fouling. If this marine growth is
excessive, it will reduce the performance of the ES120-7C. Whenever opportunity arise,
typically when the vessel is dry-docked, the transducer face must be cleaned for shells
and other marine growth.
It is important to check the transducer for physical damage. Any cracks, fractures or holes
in the red protective coating may result in a water leak, and a leak may cause irreparable
damage to the transducer.
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.
• Do not lift the transducer by the cable.
•
Do not
step on the transducer cable.
• Do not damage the transducer cable, and avoid exposure to sharp objects.
Procedure
1 Allow for sufficient access to clean and inspect the entire surface of the transducer.
2 Remove biological fouling carefully using a plastic brush, a suitable synthetic detergent
and fresh water.
Biological material which is strongly rooted in the substrate can be removed carefully
with a piece of wood or plastic. If required, you can also use citric acid. Apply, leave it
working for several hours, and rinse thoroughly with fresh water.
Note
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.
