VI. Maintenance
The only required maintenance for normal uninterrupted operation of your controller is cleaning of the
electrode(s). After initial start up, it is a good idea to clean the electrode frequently until a schedule based on
need has been developed. Since each application is unique, it is difficult to estimate the required frequency
of cleaning. The first cleaning should take place after about one week of the system being on line.
To determine the required cleaning frequency, record the reading on the controller before the electrode is
removed for cleaning. After cleaning, record the new reading. If a change is observed in the two readings,
the electrode was dirty. The more significant the change, the dirtier the electrode. If no change occurs,
cleaning needs to be done less often.
VII. Troubleshooting
The Advantage NanoTron controller is designed for many years of trouble free operation. Should a problem
occur, refer to the following chart to help identify the problem. If replacement is required, follow the procedures
