4. Maintenance

4.1 Washing the pool fi lter (backwash)

The appliance must be switched off when washing the fi lter. When the appliance is on (fi ltrati on on), press
the butt on for 5 seconds to switch it off .
Aft er cleaning the fi lter, switch the appliance on again by pressing the
resume normal operati on (producti on slaved to fi ltrati on for Ei² and GenSalt OE).
For Ei² Expert, producti on will occur as per the ti mer setti ngs.
The manufacturer cannot be held liable in case of incorrect handling.

4.2 Cleaning the electrode

The appliance 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 chlorinator and the fi ltering system, close the isolati on valves, remove the protecti on cover and disconnect
the cell power cable.
• Unscrew the ti ghtening ring and remove the cell. The ring is crenelated thus allowing a lever to be used in the event of
it jamming. Place the cell backwards and fi ll it with a cleaning soluti on so that the electrode plates are immersed.
• Leave the cleaning soluti on to dissolve the scale deposit for about 15 minutes. Dispose of the cleaning soluti 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 put it back on the cell fi xture collar (there is a foolproof marker to ensure
correct alignment).
• Refi t the ti ghtening ring, reconnect the cell cable and refi t the protecti ve cover. Open the isolati on valves and restart
the fi ltering system and chlorinator.
• If you do not use a commercially available cleaning soluti 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 protecti ve equipment!).
• Make sure that the setti ng of the polarity inversion cycles is adapted to the pool's water hardness. See
"3.2.6.b Polarity inversion" to change them.

4.3 Winterising

The chlorinator has a protecti ve system to limit chlorine producti on under bad operati ng conditi ons such as cold
water (winter) or a lack of salt.
• Acti ve winterising = fi ltering operati onal in winter: below 10 °C it is preferable to switch off the chlorinator. Above this
temperature you can leave it running.
• Passive winterising = lower water level and drained piping: leave the electrode dry in its cell with its isolati on valves
open.
