2.1.2 Appliance injec on programme
Example of 4 cycles with a set point at 7.4 pH and acid regula on (standard alkalinity):
 : 20% injec on (2 min) & 80% pause (8 min)
 : 50% injec on (5 min) & 50 % pause (5 min)
 : 75% injec on (7 min 30 sec) & 25% pause (2 min 30 sec)
 : 100% injec on (10 min)
• The injec on programme is of course inverted when a basic dosage is selected.
• Ac ve chlorine is more effi cient with the correct pH level.
• Maximum release rate is 1.5 L/h. This dosage ensures that the set point is reached quickly and
accurately.
• This propor onal injec on is cyclic and the cycle dura on is 10 minutes. The
dose will change according to the distribu on of injec on  mes and pauses.
The propor onality adjusts automa cally and the balancing between the
di erent doses is made in 0.15 pH steps.
2.1.3 Adjus ng dosage according to alkalinity
The pH level of water is poten ally unstable. Its stability is governed by the level of water alkalinity (also called "TA" for
‘‘Total alkalinity’’). If the TA is low (< 100 ppm), the pH will become poten ally unstable and conversely if the TA is high
(>150 ppm).
In order to always achieve op mal water balance, the appliance has a feature that allows users to adjust the quan ty of
corrector product poten ally injected depending on the water TA (see §"3.5.4 "Dosage" menu")
