1/ check the ph value is included between 7.0 and 7.4.
2/ Measure the free chlorine rate.
➢ If the value is week, the display flashing is normal. Proceed to a forced march of
➢ If the value is high, check that the stabilizing agent rate is too high (inferior to 20
3/ check that the salt chlorinator is well enslaved to the device, that it is not stopped and
that its production is settled at most.
If the redox value is too high (> 800 mV) :
1/ Measure the free chlorine rate.
2/ Decrease the power of the salt chlorinator production.

1/ Check that the installation is in compliance with the diagram p.6 or 7 and that the probe
is connected on the good connector (§ 3.6, p.23).
2/ Measure manually the redox value with an external plan to check the value indicated by
the device.
3/ Test the redox probe by proceeding to the calibration with a standard solution 470 mV

4/ Check that the stabilizing agent rate is not too high (inferior to 20 particle by million
recommended). A chlorine too stabilized is no more oxidizer.
Securities pH influence
If the pH is superior at 8.5, the value is really too high and influence the redox measure.

The device stops the redox regulation until the pH value comes down below 8.5. Check the
