Inspect And Clean The Underwater Connectors; Storage; Recommended Spares - Edgetech 4200 User Hardware Manual

After washing down the tow vehicle, the transducer arrays can be cleaned if needed using a mild, non-
abrasive detergent and water. Do not use any abrasive detergents or ammonia-based cleaners. After
cleaning, thoroughly spray the transducer arrays again with fresh water.

4.3 Inspect and Clean the Underwater Connectors

Regularly inspect the contacts on the male pins of each underwater connector in the tow vehicle and on
the tow cable for corrosion or oxidation. To remove any oxidation, rub the contacts lightly with 800 grit
emery cloth cut into strips equal to or less than the width of a contact. A pencil eraser can also be used
for this purpose. The female sockets can be cleaned using a cotton swab and rubbing alcohol. A .22 caliber
bore brush with only nylon bristles can be used to remove light oxidation.
To extend the life and increase the reliability of the connectors, apply a thin film of silicone dielectric
grease, such as Novagard G624 general purpose silicone grease or an equivalent, to the entire surface of
each male pin. A small amount of grease should also be applied to the opening of each female socket.
NOTE:
connector when not in use to prevent damage.

4.4 Storage

When not in use, all the components of the 4200 Series High Definition Dual-frequency Side Scan Sonar
System should be packed in their original shipping containers in the same manner in which they were
originally shipped. Store the equipment in a dry area until needed for another survey.

4.5 Recommended Spares

EdgeTech recommends purchasing spare parts, such as circuit boards, power supplies, cables, and other
critical items, at the same time as purchasing the original equipment. Doing so ensures that all spares are
of the same make and model as the originals installed in the equipment. All spares are optional, but a few
are recommended. For a list of these recommended items, contact
of purchase.
