Section 7: System Description
Revision – September 2009 7 - 15
This sequence does not remove hazardous
gases to a low enough concentration to
permit operator maintenance or other
activity on the process line or downstream
components. The customer must develop
purge and evacuation procedures for the
process line and components downstream
of the Distribution System to assure
acceptable low concentrations of
hazardous gas to permit maintenance of
this equipment.
NOTE: Either the Flow Purge or the Rough Line Evacuation
sequence will be installed in the TE10 controller per the original
order. See the System Specific Information provided with the
equipment to determine which process line purging sequence is
installed for this system.
