Maintenance of the electrolysis cell
EN
The electrolysis cell must be kept in suitable conditions to ensure a long lifetime. This salt chlorination unit has an automatic
electrode cleaning system that helps to prevent scale build-up on the electrode surface. If the salt chlorination system is
operated in accordance with these instructions, and in particular if the pool water balance is kept within the recommended
parameters, it should not be necessary to manually clean the electrodes. However, if the pool water and the salt
chlorination system are not maintained in line with these instructions then it may be necessary to manually clean the
electrodes following the procedure outlined below:
1.Cut off the 230 Vac unit's supply.
2.Unscrew the closing nut located at the end where the electrodes are located, and remove the electrode package.
3.Use diluted hydrochloric acid (a part of commercial acid in 10 parts of water), submerging the electrode package in the
prepared solution for no more than 10 minutes.
4.NEVER SCRAPE OR SWEEP THE CELL OR THE ELECTRODES.
The electrodes of a salt chlorination system comprise of a titanium sheet coated with a layer of noble metal oxides. The
electrolysis processes that take place on their surface produce a progressive wearing down – the electrodes do have a
finite life. In order to optimise electrode lifetime, please consider the following aspects:
1.Although all salt electrolysis units are SELF-CLEANING, a prolonged operation of the system at pH values over 7.6 in
waters of high hardness can produce scale formation on the surface of the electrodes. Scaling on the electrodes surface
will progressively deteriorate the coating, causing a decrease of lifetime.
2.Manually cleaning/washing the electrodes (as described above) will shorten their life.
3.Prolonged operation of the system at salinities lower than 3 g/l (3000 ppm) will cause a premature deterioration of the
electrodes.
4.Frequent use of copper based algaecides will promote the formation of copper deposits on the electrodes, progressively
damaging the coating. Remember that chlorine is the best algaecide.
Electrodes
The system has a light indicating malfunction of the electrolysis cell electrodes. This usually occurs at the end of the
electrodes 'useful life, when they lose their power. However, although this is a self-cleaning system, this malfunction could
also be due to excessive scaling on the electrodes when the system operates with hard water with a high pH value.
In case of replacement of electrodes, remove the temperature probe to insert it into the new replacement.
