This process is performed three times. The programme will then calculate the mean
of the three samples and thus determine the chlorine consumption of the dosing
system.
Once the last weight has been entered, the device shows the dosing performance
during continuous operation. Confirm this value with OK and change to the start
screen using the Return button (white arrow).

Section 6.2.8, Settings;
Appropriate dosing performances for chlorine and acid can be set in the menu. The
value for chlorine should not be lower than 50%, due to the sensitivity of the
"Chlorine missing" switch on the dissolving cyclone.
The dosing performance for acid must be set to ensure that the chlorine solution
is pH-neutral (pH 7.0 +/- 0.2). The chlorine and acid dosing must be matched
according to the concentration of the chlorine granulate, the hardness of the
dissolving water / swimming pool water, its pH value and the acid concentration.
The acid dosing is initially set to 50% of the chlorine dosing performance (e.g. 50%
chlorine and 25% acid) using 37% sulphuric acid. The pH value of the chlorine
solution must be measured and evaluated after the first filling and mixing of the tail
for approx. 2-5 minutes; pH value too high: more acid; pH value too low: less acid.
Repeat this process until the pH value is in order.
