6 Operating in CI Mode
The CI Flow Control Module
When a CI system is installed along with a JetClean system, the MFC is shared
by both systems. By design, its use is restricted to one of these systems at a
time. In this case, the Gas B supply is dedicated to hydrogen used for source
cleaning. For detailed information on the JetClean system refer to the JetClean
Operating manual installed on your PC along with this manual.
