Replacing Optional Anti-Foulant Devices (SBE 49)
As an option, the FastCAT is supplied with anti-foulant device fittings and
Anti-Foulant Devices. The Anti-Foulant Devices are installed:
• in the T-C Duct assembly;
• in the anti-foulant device cup and cap (part of the external pump exhaust
tubing).
Wearing rubber or latex gloves, follow this procedure to replace each Anti-
Foulant Device (two):
Anti-Foulant Device in T-C Duct Assembly
1. Remove the large screw securing the T-C Duct to the mast.
2. Gently pull the T-C Duct straight out - you will feel some resistance as the
seals disengage. Do not twist the T-C Duct or apply any sideways
motion, or you may damage the conductivity cell.
3. Remove the two small Phillips-head screws securing the T-C Duct top to
the T-C Duct base.
4. Pull the T-C Duct top off of the base.
5. Remove the old Anti-Foulant Device. If the old device is difficult to
remove, use needle-nose pliers and carefully break up material.
6. Place the new Anti-Foulant Device in the T-C Duct base.
7. Replace the T-C Duct top on the base, reinstalling the two small Phillips-
head screws.
8. Carefully slide the T-C Duct assembly over the temperature sting,
aligning the large screw hole with the screw hole in the mast. Push the
assembly onto the end of the conductivity cell - you will feel some
resistance as the seals engage. Do not twist the T-C Duct or apply any
sideways motion, or you may damage the conductivity cell.
9. Reinstall the large screw to secure the assembly to the mast.
