The electrt$•sis cel must be kept in suitable conditions to ensure a bng [fetime. This salt chlorination unit has an automatic
electrode cleaning system that helps to prevent scale build-up on the electrode surface. If the salt chlorination system is
operated in accordance with these instructions, and in particular if the pool water balance is kept within the recommended
parameters. it should not be necessary to manualy dean the electrodes. However, if the pod water and the salt
chlorination system are not maintained in line with these instructions then it may be necessary to manually cban the
electrodes folbwing the procedure outlined below:
I.Cut off the 230 Vac unit's sup$'.
2.1Jnscrewthe &sing nut located at the end where the ekctrodes are located, and remove the electrode package.
3.1Jsedluted hydrochbric acid (a part Ofcommercial acid in 10 parts Ofwater), submerging the electrode package in the

4.NEVER SCRAPE OR SWEEP
The electrodes of a salt chlorination system comprise of a titanium sheet coated with a layer of noble metal oxides. The
electrdysis 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, g*easeconsider the folbwing aspects:
IAthough al salt electroysis
waters of high hardness can produce scale formation on the surface of the electrodes. Scaling on the electrodes surface
wil progressively deteriorate the coating, causing a decrease Of lifetime.
2.Manually cleaning/washing the electrodes (as described above) wil shorten their life.
3.Prolonged operation Of the system at sainities lower than 3 gn (3000 ppm) will cause a premature deterioration Ofthe
