Maintenance and Troubleshooting
Extended Shutdown
If analyzer is planned to stop running over 2 weeks, extended
shut down need to be performed. To avoid clogging, flush the
entire system with distilled water before shutdown.
Disconnect and empty out the reagents box and flush the
lines by using distilled water in the grab sample bottle. Put
reagent cap in a beaker contains distilled water. Use the Grab
Sample Analysis for 15 minutes to allow for extended flushing.
Remove the electrode from the flow cell and let it hang dry by
its cable.
Complete Removal
For complete removal from service, disconnect the
equipment using the following steps:
1. Remove electric power through appropriate local Lock
out / Tag Out procedures.
2. Shutoff flow to the TRO analyzer.
3. Remove reagent from the analyzer.
4. Disconnect all tubing connected to the TRO analyzer.
5. Remove the mechanical fasteners for complete removal.
Sensor
The TRO sensor should be inspected every 6 months for
damage or discoloration. If necessary, it can be
refurbished or replaced.

of the reagent bag and twist counter-clock to
remove the cap from reagent bag.
Do NOT re-use or re-fill old or existing reagent
boxes. Dispose of the used boxes and contents
safely and according to local regulations.
