8. Care and Maintenance

There are no user serviceable parts within the mini series other than changing batteries. See section 5.2. The

instruments are remarkably robust, being primarily constructed of titanium. The only maintenance required, other

than periodic recalibration as necessary, is to keep the sensor as clean as possible.

After use, rinse all parts in fresh water removing any growth or debris as necessary, but take exceptional care not

to touch or damage the pressure diaphragm itself, if fitted.

The following handling procedures should be adopted when using SubConn connectors:

The connector should not be exposed to long term heat or sunshine.

If this occurs, and the connectors are very dry, soak in fresh water before use.

Ensure the connectors are lubricated - the recommended lubricant is:

Loctite 8021 in a spray can

Molykote 44 Medium - but use very sparingly.

Any accumulation of sand or mud in the female contact should be removed with fresh water. Failure to do so

could result in the splaying of the female contact and damage to the O-ring seals.

When using bulkhead connectors ensure that there are no angular loads as this destroys the connector.

Connectors must be greased with Molykote 44 Medium before every mating

A layer of grease corresponding to minimum 1/10 of socket depth should be applied to the female connector

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

After greasing, fully mate the male and female connector in order to secure optimal distribution of grease on

pins and in sockets

To confirm that grease has been sufficiently applied, de-mate and check for grease on every male pin. Then

re-mate the connector

When disconnecting, pull straight, not at an angle
