With this dosing method, the chlorine content must be measured regularly using a color
method. If the chlorine content is too low, the time must be extended. If the chlorine
content is too high, the time must be reduced.
11.3) PH+ or PH-
Press the lower button. The setting "PH+ or PH-" is now checked. Press
the middle button to activate this setting. A - sign appears. Press the
middle button again. You have now set the supply of PH-.
PH- must always be set when using liquid chlorine. Liquid chlorine
already contains PH+. This is always added as a stabilizer.
PH- should always be set when using salt electrolysis. When chlorine is produced by the salt
electrolyzer, PH+ (NaOH) is formed as a by-product.
We recommend the use of 15% sulfuric acid, the weaker the sulfuric acid and the more
accurately the pH dosage will work
In the exceptional case that the pH drops below 7.2, it is best to bring it back to zone 7.2-7.6
by manually adding pH plus
As an additional safety measure, we recommend that - when the pH minus canister is full -
the suction nipple is not lowered to the bottom of the canister. If something should go
wrong with the dosage, the entire canister of acid will not be pumped into the pool.
It is not possible to apply both PH+ and PH- : PH- or PH+, never both at the same time.
11.4) PH SP(SetPoint)
Press the lower button. The "PH SP" setting is now checked. Press the
middle key to activate this setting. You will now see the preset value. Now
you can set the value higher or lower with the upper or lower button and
confirm by pressing the middle button. The value is now set according to
your needs.
