Important
The steps outlined here will expose sensitive electronic equipment and so
appropriate steps should be taken to prevent any static discharge occurring
which may harm the equipment.
Caution
Servicing of the SeaKing unit should only be carried out by competent personnel
in a dry, clean environment with full ESD precautions.
Service tools required
• Clean absorbent wipes
• Silicon grease MS-111 lubricant (or equivalent)
• A M3 Allen Key or Hex driver
• A 5.5mm spanner, or nut spinner
• A small nose flush plier, or M2.5 spanner
Procedure
1. Rinse the unit and connector in fresh water and dry with absorbent wipes
2. Using the M3 Allen key, loosen each of the retaining screws of the Pressurised blanking
cap (if present)
3. Using the M3 Allen key, loosen each of the retaining screws of the MAIN and AUX (if
present) waterblocks. Each screw should be loosened by a quarter turn in order to prevent
damage to the screw threads.
4. Remove the connector endcap locking ring
5. Using the endcap puller, pull the connector endcap off the unit
6. The electronics block will then slide out of the housing attached to the connector endcap.
7. On the top of the electronics block, use the 5.5mm spanner to carefully remove the two
retaining nuts and the short nose flush pliers to remove the two bullet posts
8. In turn, remove each PCB and each set of four stand off posts underneath until only the
PCB closest to the endcap remains – the COM PCB
9. Remove the last PCB and then unscrew the four guide posts from the connector endcap
Once fully disassembled, inspect the various o-ring seals and sealing surfaces for signs of
damage and corrosion. Pitting and corrosion within an o-ring sealing area can cause a unit
to lose integrity and lead to water ingress and significant damage.
