7.4 'TEST CELL'
Interpretation:
The electrode is dirty, scaled and/or worn.
Possible causes:
Faulty filtering (pre-filter or diaphragm), water too hard (TH), electrode too old.
This message will also de displayed after 9,000 hours of operation of the Ei cell, to have your
retailer check the condition of the cell.
Solutions:
> Clean and/or check the filtering system (pump & filter).
> Check the TH level and add calcium sequestering products if needed. Change the polarity
inversion cycle intervals if the TH > 40 °f or 400 ppm (see the important note in the Inspecting
and cleaning the electrode paragraph).
> Replace the electrode with a new one.
7.5 « INVERSION»
Interpretation:
The Ei chlorinator is inversing the cell polarity. This is an automatic self-cleaning cycle; the message
does not indicate an error but is displayed for information purposes only.
Solution:
Wait for about 10 minutes and the chlorine production will resume automatically at the set levels.
