Rule for injecting pH Perfect

Proportional cyclic dosing - exclusive to Zodiac
• To reach the set point in the best possible conditions (the quickest, but with
the least possible corrective solution), your pH Perfect automatically detects
the difference of the pH value measured in the pool compared with the desired
set point (default value = 7.4 pH).
• This proportional injection is cyclic and the cycle time is 10 minutes.
What will change in dosing is the different times of injection and pause.
• This type of dosing makes it possible to reach the set point quickly and precisely
with the following advantages:
– Optimal consumption of corrective solution (better balance of water, little
action on the buffering capacity or TAC).
– Water treatment functioning in the best conditions (the active chlorine is
more effective with a good pH).
Rule for injecting pH Perfect
The proportions are adjusted automatically and the different dosages are
distributed in steps of 0.15 pH.
• E.g.: For 4 cycles with a set point of 7.4 pH and acid regulation (pH minus):
– pH ≤ 7.55 : 20 % injection (2 minutes) & 80 % pause (8 minutes)
– pH ≤ 7.70 : 50 % injection (5 minutes) & 50 % pause (5 minutes)
– pH ≤ 7.85 : 75 % injection (7 minutes 30 secondes) & 25 % pause
(2 minutes 30 secondes)
– pH ≥ 7.90 : 100 % injection (10 minutes, continuous)
Note: The rule for injecting is reversed if an alkaline dose is chosen.
