3. Remove the tubing and lift the rotameter up and out of the bracket.
4. Loosen the tube nut, flat of male thread and washer on the new
rotameter and insert into the bracket openings with the flat of male
thread and washer on the inside of the bracket (analyzer side) and
the white plastic base against the outside bracket edge.
5. Tighten the flat of male thread and washer to hand tight.
6. Use the 7/8” wrench to further tighten with a 1/8 turn to secure.
7. Reinstall the tubing into the inlet and outlet of the rotameter.
8. Tighten the tube nut with a 7/16” open-end wrench while holding the
flat of male thread with the extra-thin 5/8” open-end wrench about
a 1/8 turn.
9. Refer to the section called “To start up the simplified sample
system” on page 4-7 to put the system back online.
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 4-9.
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. 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
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.
