11.3) PH+ of PH-
Press the bottom button. The "PH+ or PH-" setting is now highlighted.
Press the center button to activate this setting. On - sign appears. Press
the middle button again. You have now turned on the power supply
with PH-.
PH- should always be adjusted when salt electrolysis is used. When
chlorine is produced by the salt electrolysis unit, PH+ (NaOH) is formed as a
by-product.
PH- should always be adjusted when liquid chlorine is used. After all, liquid chlorine already
contains PH+, which is always added as a stabilizer.
PH- should always be adjusted when using the salt electrolysis. When chlorine is produced by the
salt electrolysis unit, PH+ (NaOH) is produced as a by-product.
It is not possible to add PH+ AND PHOTO: PH or PH+, never both at the same time.
In other cases, PH plus can be adjusted.
11.4) PH SP(SetPoint)
Press the bottom button. The "PH SP" setting is now activated. Press the
center button to activate this setting. You will now see a preset value.
Now you can move the value up or down with the top or bottom key.
Then confirm with the middle button. The value is now set according to
your needs.
As a rule, the pH value is set to 7.4.
11.5) Rx SP (Redox SetPoint)
The redox is a measure of the chlorine content.
During commissioning, we recommend setting the set point to 700 mV,
as described above for the pH value. After the first commissioning,
measure the chlorine content using a colour method. If necessary,
adjust the redox setpoint (decrease if the chlorine content is too high,
increase if the chlorine content is too low).
Read carefully the chapter "Setting the Rx setpoint" in the manual
