Section 8 – Maintenance

8.1 Introduction

Before any maintenance activity is carried out on the equipment, ensure

Section 2 "Safety"

is read and

fully understood.

8.2 Retrieval from the Water

See

Section 7 "Retrieval and Storage"

8.3 Cleaning

Clean the transponder as follows:

1. Thoroughly wash the transponder in warm clean fresh water to remove accumulations of salt,

sand or silt and marine growth, paying particular attention to the electrical connectors.

Note

Do not use any abrasive brushes or sharp tools to remove marine growth when cleaning the

instrument as this will damage the protective coating and increase the risk of corrosion.

2. If a sound speed sensor is fitted, clean the transducer and reflector faces with warm clean fresh

water.

3. Remove any attached cabling or dummy plugs/protective caps and wash the external socket.

4. Dry the instrument and any attached cabling with a clean lint free cloth.

5. Replace any dummy plugs/protective caps.

8.4 Inspection

Regularly inspect the instrument for the following:

1. Inspect the Pressure Relief Vent Valve;

Section 4.2.1 "Check the Pressure Relief Vent Valve"

2. Inspect the housing for signs of corrosion or damage. When in full working depth, the housing is

at risk of failure if corrosion or damage is present. If any corrosion is found it can be treated as
described in

Section 8.12 "Corrosion Removal"

3. Inspect the connectors and cables for signs of abrasion, damage or corrosion.

4. Check the security of the connector by fitting the locking sleeve from the mating half of the

connector, and check for movement. Any movement will require attention and the connector to
be secured.

5. Inspect the jointing faces of the endcaps and the main housings. Signs of corrosion indicate

leakage of water into the transponder.

6. Check the guard for distortion.

7. Check there is sufficient zinc remaining on the anodes, replace if necessary.

8. Inspect the rubber boot on the transducer for signs of splitting.

9. Check the brass filling screw is in place.

10. Inspect the connector contacts for signs of corrosion.
