Handling of underwater connectors
Correct handling of the underwater connectors is very important to avoid any leakage
and corrosion problems to the EM 2040C transducers.
Important
You must follow these instructions carefully to ensure correct use of your SubConn ®
underwater connectors.
1 Disconnect the connector by pulling it straight out, not at an angle. Do not pull
the cable, and avoid sharp cable bends.
2 The connectors must not be exposed to long periods of heat or direct sunlight. If a
connector becomes very dry, it should be soaked in fresh water before use.
3 General cleaning and removal of any accumulated sand or mud on a connector
should be performed using spray based contact cleaner (isopropyl alcohol). New
grease must be applied again prior to mating.
4 Always apply grease before mating.
Greasing and mating above water (dry mate):
a Connectors must be greased with Molykote ® 44 Medium before every mating.
b A layer of grease corresponding to minimum 1/10 of socket depth should
be applied to the female connector.
c The inner edge of all sockets should be completely covered, and a thin
transparent layer of grease left visible on the face of the connector.
d After greasing, fully mate the male and female connector in order to secure
optimal distribution of grease on pins and in sockets.
e To confirm that grease has been sufficiently applied, de-mate and check for
grease on every male pin. Then re-mate the connector.
Greasing and mating under water (wet mate):
a Connectors must be greased with Molykote
®
44 Medium before every mating.
b A layer of grease corresponding to approximately 1/3 of socket depth should
be applied to the female connector.
c All sockets should be completely sealed, and transparent layer of grease left
visible on the face of the connector.
d After greasing, fully mate the male and female connector and remove any
excess grease from the connector joint.
The recommendations from the manufacturer of the underwater connectors may be
subject to change without prior notice. Please refer to the manufacturers website for
updated information.
