Periodic SCS Maintenance
The status of the SCS should be checked regularly to confirm proper operation
(pressures, flows, etc.) and detect potential problems or failures before
damage occurs. If maintenance is required, isolate the part of the system to be
serviced by following the appropriate procedure under “Shutting Down the
SCS” on page 3-10.
All filter elements should be checked periodically for loading. Obstruction of a
filter element can be observed by a decreasing supply pressure or bypass flow.
If loading of a filter is observed, the filter should be cleaned and the filter
element replaced. Refer to “To check the filter” on page 3-15 and “To
replace the filter” on page B-3 for instruction. After observation for some
time, a regular schedule can be determined for replacement of filter elements.
No other regularly scheduled maintenance should be required for the system.
Preventive and On-Demand SCS Maintenance
Preventive and on-demand maintenance will be required when components
and parts deteriorate or fail as a result of continuous use. The performance of
the entire SCS and individual components should be monitored regularly so
that maintenance may be performed on a scheduled basis in order to prevent
a failure that could take the system out of operation.
The SCS is designed for convenient removal and replacement of component
parts. Complete spare components should always be available. In general, if a
problem or failure occurs, the complete part should be removed and replaced
to limit system down time. Some components may be repaired (replacement
of seats and seals, etc.) and then reused.
If the sample transport line does not appear to completely clear during normal
operation, it may be necessary to clean the sample transport line to remove
any liquid that may adhere to the wall of the tubing. The sample transport line
should be purged dry with air or nitrogen before the system is placed back in
operation.
Due to the chemical properties of the process samples, care must
be taken to repair or replace components with proper materials of
construction. Maintenance personnel should have a thorough
knowledge and understanding of the chemical characteristics of
the process before performing maintenance on the SCS.
