Electrolysis cell maintenance
The cell must be maintained in good condition to ensure it remains operational for a long time. The salt electrolysis system has
an automatic electrode cleaning system that prevents scale buildup on the electrodes, so it is unlikely that there will be any need
to clean them. However, if it is necessary to clean the inside of the cell, proceed as follows:
1. Disconnect the 230 V AC power supply from the device.
2. Unscrew the locking nut at the end of the electrode and remove the electrode pack.
3. Use a dilute solution of hydrochloric acid (one part acid to 10 parts water), immersing the electrode pack in the solution for
a maximum of 10 minutes.
4. NEVER SCRAPE OR BRUSH THE CELL OR ELECTRODES.
The electrodes of a salt electrolysis system consist of titanium plates coated with a layer of noble metal oxides. The electrolysis
processes that take place on their surface cause their progressive wear, so the following aspects should be taken into account
in order to optimise the lifetime of the electrodes:
1. Although these are SELF-CLEANING salt electrolysis systems, prolonged operation of the system at pH values above
7.6 in hard water can cause scale deposits to build up on the surface of the electrodes. These deposits will progressively
deteriorate the coating, leading to a decrease in its service life.
2. Frequent cleaning/washing of the electrodes (as described above) will shorten their service life.
3. Prolonged operation of the system at salinities below 3 g/L causes premature deterioration of the electrodes.
4. Frequent use of algaecide products with a high copper content can lead to the deposit of copper on the electrodes, gradually
damaging the coating. Remember that the best algaecide is chlorine.
Electrodes
The system has a malfunction indication LED for the electrodes of the electrolysis cell. This malfunction will normally be due to
electrode passivation once they have reached the end of their service life. However, despite being a self-cleaning system, this
malfunction could also be due to excessive scale buildup on the electrodes if the system is used in hard water or water with high pH.
