Checking The Sample Pump - GE Sievers 900 Series Operation And Maintenance Manual

10. After 10 minutes, open the Analyzer case and check the tubing that leads to the resin bed
(ion exchange column). Most of the air originally in the tubing should be replaced with
water. If more than a few small bubbles remain in the tubing, repeat Steps 6 through 9.
To troubleshoot a lack of flow through the Analyzer, follow the steps in the next three sections:
"Checking the Sample Pump," "Checking the Inlet Tubing," and "Backflushing the Analyzer."

Checking the Sample Pump

While the Analyzer is operating, open the cover and make sure the sample pump is turning. If the
pump is not turning and the Analyzer is operating (the display screen indicates that analysis is
taking place), contact GE Analytical Instruments Technical Support for instructions.
To avoid potentially dangerous shock, do not touch anything inside
the Analyzer while observing the sample pump.
