Specification of Ph addition
The pH value is corrected with pH min. We recommend the use of 15% -30% sulfuric acid,
the weaker the sulfuric acid and how accurate 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 adding pH plus.
As an additional safety measure, we recommend that you do not lower the suction cup to
the bottom of the canister. If something would go wrong with the dosage, the whole can
will not be pumped acid into the pool.
Calibration and verification Chlorine /Ph
The correctness of pH and Chlorine must be regularly (weekly) verified by means of a
proper measurement with color (for example Poollab ZWMX1060.
Every installation should be calibrated at least once a year. In case of a long swimming
season, or in case of deviation between color method measurement and pH/Rx values, it is
advisable to also calibrate half-yearly, i.e. twice a year.
The procedure for calibrating and adjusting the setpoint has already been described in
detail above.
Connecting a flow switch
A flow switch can be added to the unit, for units produced in 2020 or later.
On the circuit board with the display, there is the connection "FS" at the bottom left. These
are connected to the two contacts of the flow switch. If no flow is detected, neither acid
nor chlorine pump will run, and an alarm will be generated.
