Maximum permissible operating pressure:
In the sample water line: 2 bar at 30 °C (sample
water)
1.
Tighten all threaded connectors prior to initial commissioning
2.
Open the shut-off valves downstream of the metering pumps,
in the sample water line and also the shut-off valves in your
system
3.
Insert the suction lances into the relevant chemical storage
tanks for acid or disinfectant (e.g. sodium-calcium hypo‐
chlorite)
4.
Plug the mains plug into the socket and switch on the mains
voltage
6.1 Setting the setpoint for pH
You need to adjust the pH in the swimming pool water to a setpoint
of pH 7.2 during commissioning, as the pH of the water can be
between 6.5 and 7.8 depending on the treatment method and
water quality. As the disinfection effect of the chlorine decreases
with higher pH values and, on the other hand, pH values below 7
can scarcely be determined using the phenol red method, we rec‐
ommend pH 7.2 as a setpoint. The handling of the controller is
described in chapter
Chapter 7 ‘Operating and replacing the
6.2 Setting the setpoint for ORP
The redox potential is a parameter for presenting the oxidative and
therefore disinfecting effect of the chlorine. You need a minimum
redox potential of 650 mV for a disinfecting effect. Ensure that the
redox potential is at least 700 mV, taking into account measuring
inaccuracies and to achieve adequate disinfection speed. The han‐
dling of the controller is described in chapter
ating and replacing the storage tank’ on page 23.
The chlorine content should be between 0.3 and 1.0 mg/l,
depending on the treatment method and type of swimming pool, in
compliance with the German Swimming Pool Standard DIN 19643.
The redox potential is also influenced by other constituents in the
water and, above all, also by the pH value as well as the chlorine
content. The direct correlation between the chlorine content and
redox potential differs in each swimming pool and can change over
time.
We therefore recommend first setting a chlorine content of approx.
0.5 mg/l and a pH of 7.2 in the swimming pool water and carrying
over the redox potential measured by the controller as the setpoint,
providing it lies above 700 mV. The chlorine content can be
increased, if necessary, if the redox potential lies below this level.
