I Inspecting And Cleaning The Electrodes - Zodiac eXPERT Manual De Instalación Y De Uso

6.2 I Inspecting and cleaning the electrodes
The appliance is equipped with a smart polarity inversion system designed to prevent the electrode plates
from scaling. The polarity reversal time can be modified, see § "4.3.4. "Reverse direct": Reversal adjustment
for cell cleaning". 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 discon-
nect the cell power cable.
• Unscrew the tightening ring and remove the cell. The ring is crenelated thus allowing a lever to be used in the event
of it jamming (see figure
• Submerge the part containing the electrode plates in a suitable recipient containing a cleaning solution (see figure
).
• Leave the cleaning solution to dissolve the scale deposit for about 10 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 an alignment foolproofer).
• 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 10 parts water. (Caution: always pour
the acid into the water and not the opposite and wear suitable protective equipment).
