Properties and conditions of use of the cell :
• When the water temperature descends below 15°C, its chemical properties cause premature wear to the cell.
In this situation, turn off the electronics unit.
• The water in the cell must not freeze under any circumstances.
• Provided the cell is not connected to a power supply, leaving it installed on the pipework poses no risk of
deterioration. In this instance, carry out a suitable chemical treatment, preferably without the use of stabilisers.
