2.1.2 Appliance injecti on programme
Example of 4 cycles with a set point at 7.4 pH and acid regulati on (standard alkalinity):
• pH ≥ 7.55: 20% injecti on (2 min) & 80% pause (8 min)
• pH ≥ 7.7: 50% injecti on (5 min) & 50 % pause (5 min)
• pH ≥ 7.85: 75% injecti on (7 min 30 sec) & 25% pause (2 min 30 sec)
• pH < 7.9: 100% injecti on (10 min)
• The injecti on programme is of course inverted when a basic dosage is selected.
• Acti 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 proporti onal injecti on is cyclic and the cycle durati on is 10 minutes. The
dose will change according to the distributi on of injecti on ti mes and pauses.
The proporti onality
diff erent doses is made in 0.15 pH steps.
2.1.3 Adjusti ng dosage according to alkalinity
The pH level of water is potenti 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 potenti ally unstable and conversely if the TA is high
(>150 ppm).
In order to always achieve opti mal water balance, the appliance has a feature that allows users to adjust the quanti ty of
corrector product potenti ally injected depending on the water TA (see §"3.5.4 "Dosage" menu")
