Keep the key "SET" pressed until the indicator signals the required ORP value within the
range 600 ÷ 850 mV and release it release it after it has been selected.
The pH integrated regulator is equipped with a safety system (PUMP-STOP FUNCTION)
which intervenes on the pump and makes it possible to avoid the following situations:
Damages to the pump caused by its dry operation (draught can with exhausted acid)
Over dosage of pH-minus product (damaged or worn out sensor).
pH adjusting problems due to the high alkalinity of the water (recently filled pool, high
carbonate levels).
When the PUMP-STOP function is enabled (factory configuration), the system stops
the dosing pump after the set time (1hr) has elapsed without having reached the pH set
point.
The pH display shows the code E2
At this point, check as follows:
Proper operation of the pH sensor;
pH-minus tank level;
Water alkalinity (probable high level).
