8. Maintenance
8.1. ELECTROLYSIS CELL
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:
• Stop the electrolysis system and the rest of equipment of the pool.
• Close valves and empty the electrolysis cell.
• 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.
• 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 nite life. In order to optimise electrode
lifetime, please consider the following advices:
• Although all Astralpool Chlore 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.
• Manually cleaning/washing the electrodes (as described above) will shorten their.
• Prolonged operation of the system at salinities lower than 3 g/l (3000 ppm) will
cause a premature deterioration of the electrodes.
• Frequent use of copper based algaecides will promote the formation of copper
deposits on the electrodes, progressively damaging the coating.
8.2. CALIBRATION OF THE PH SENSOR
The integrated pH-controller has two calibration modes of the pH-electrode: “FAST” and
“STANDARD”. We recommend carrying out it at least once a month during the period of use of
the swimming pool.
