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.
Warning
To avoid potentially dangerous shock, do not touch anything inside
the Analyzer while observing the sample pump.
