4. Maintenance
4.1 Cleaning the electrode
The electrolyser is equipped with a smart polarity inversion system designed to prevent the electrode plates from
scaling. However cleaning may be required in regions where the water is very hard.
• Turn off the electrolyser and the fi ltering, close the isola on valves, remove the protec on cover and disconnect the
cell power cable.
• Unscrew the  ghtening ring and remove the electrode from the body of the cell. The ring is crenelated thus allowing a
lever to be used in the event of it jamming. Place the electrode in a cleaning solu on without immersing the connec on
terminals.
• Leave the cleaning solu on to dissolve the scale deposit for about 15 minutes. Dispose of the cleaning solu on at an
approved waste recycling site, never pour into the rainwater drainage system or into the sewers.
• Rinse the electrode using clean water and refi t it into the body of the cell (there is a fail-safe on the alignment).
• Refi t the  ghtening ring, reconnect the cell cable and refi t the protec ve cover. Open the isola on valves and restart
the fi ltering and electrolyser.
• If you do not use a commercially available cleaning solu on, you can manufacture it yourself by carefully
mixing 1 volume of hydrochloric acid with 9 volumes of water (Warning: always pour the acid into the
water and not the opposite and wear suitable protec ve equipment!).
• If the water is too hard (high carbonate content, HL>40 °f or 400 ppm), it is possible to change the polarity
inversion cycle  mes on your electrolyser to have more eff ec ve electrode self-cleaning. Consult your
reseller if you are in this situa on (professional access).
4.2 Wintering
The electrolyser has a protec ve system to limit chlorine produc on under bad opera ng condi ons such as cold
water (winter) or a lack of salt.
• Ac ve wintering = fi ltering opera onal in winter: below 10°C it is preferable to switch off the electrolyser. Above this
temperature you can leave it running.
• Passive wintering = lower water level and drained piping: leave the electrode dry in its cell with its isola on valves open.
