7.2 I Inspecting 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 duration can be modified, see
“5.2.13 Configuring the duration of polarity
reversal”
. However cleaning may be required in regions where the water is very hard.
•
Turn off the appliance and the filtration system, close the isolation valves, remove the protection cover and
disconnect the cell power cable.
•
Unscrew the compression ring and remove the cell,
see figure
. 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 solution.
•
Leave the cleaning solution to dissolve the scale deposit for about 15 minutes. Dispose of the cleaning
solution 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 fixture collar (there is a foolproofing key
to ensure correct alignment).
•
Refit the tightening ring, reconnect the cell cable and refit the protective cover.
•
Re-open the isolation valves and restart the filtering system and appliance.
If you are not using a commercially-available cleaning solution, you can make your own by
carefully mixing 1 part hydrochloric acid with 9 parts water. (Caution: always pour
the acid into the water and not the opposite and wear suitable protective equipment!).
