Diagnostics
If you are sure none of the upstream flow system components are leaking,
check for leaks at the column fitting and plugged inlet. If you find leaks, tighten
the fittings and repeat the leak test.
If you can find no other leaks, the µ-ECD itself is probably leaking. The µ-ECD
Note
cannot be disassembled without special license from the Nuclear Regulatory
Commission or Agreement State Licensing Agency (USA only).
