2.1.2 Appliance injection programme
Example of 4 injection cycles with a set point at 650 mV:
• Redox ≥ 580 mV: 20% injection (2'') & 80% pause (8'')
• Redox ≥ 510 mV: 50% injection (5') & 50 % pause (5')
• Redox ≥ 530 mV: 75% injection (7'30'') & 25% pause (2'30'')
• Redox < 530 mV: 100% injection (10 minutes)
This proportional injection is cyclic and the cycle duration is 10 minutes. What changes the doses is the distri-
bution of injection times and pauses. The proportionality automatically adjusts and the balancing between the
different doses is made using 70 mV steps.
The appliance uses measurements of the disinfectant capacity of the water (= potential Redox) to determine whether
chlorine should be injected or not. However, 2 parameters have a significant influence on the potential Redox:
- water pH: ideally it should be between 7.2 and 7.4.
- the level of chlorine stabiliser in the water (= cyanuric acid): do not exceed 30 mg/L, otherwise the potential Redox will
be significantly reduced (and the set point will need adjusting accordingly).

2.2.1 Sensor location
• The Redox sensor must be placed after the filter and before the heating system,
• It must be placed vertically or sloping at a maximum of 45°, it should never point downwards.
