7.2 I Inspecti ng and cleaning the electrodes
The appliance is equipped with a smart polarity reversal system designed to prevent the electrode plates
from scaling. The polarity reversal durati on can be modifi ed, see
“5.2.13 Confi guring the durati on of polarity
reversal”
. However cleaning may be required in regions where the water is very hard.
•
Turn off the appliance and the fi ltrati on system, close the isolati on valves, remove the protecti on cover and
disconnect the cell power cable.
==> eXO®(iQ) cell:
•
Unscrew the compression ring and remove the cell,
see fi gure
. The ring is crenelated thus allowing a
lever to be used in the event of it jamming. Submerge the part containing the electrode plates in a suitable
recipient containing the cleaning soluti on.
==> GenSalt OT cell:
•
Positi on the cell upside down and fi ll it with a cleaning soluti on such that the electrode plates are
submerged.
eXO® (iQ) cell
•
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 foolproofi ng key
to ensure correct alignment).
•
Refi t the ti ghtening ring, reconnect the cell cable and refi t the protecti ve cover.
•
Re-open the isolati on valves and restart the fi ltering system and appliance.
If you are not using a commercially-available cleaning soluti on, you can make your own by
carefully mixing 1 part hydrochloric acid with 9 parts water. (Cauti on: always pour
the acid into the water and not the opposite and wear suitable protecti ve equipment!).
