Swimming pool salt electrolysis works perfectly when the electrodes are clean. Conductivity and chlorine production are then at their peak. This chemical process requires little maintenance, nevertheless it is still essential to clean regularly.
Why Clean The Salt Chlorinator Cell
There are two reasons for descaling the salt chlorinator cell.
The first, because the lime, by attaching itself to the electrodes, decreases or prevents a normal production of salt. A thin layer of limestone decreases the production of chlorine and the disinfection of the swimming pool suffers, the water becomes cloudy, green.
The second reason, this cleaning will make it possible to keep the cell in good condition, to prolong its life by avoiding the premature erosion of the electrodes.
When Do You Need To Clean The Salt Chlorinator Cell
Descaling is to be carried out according to how clogged the cell is and how hard is the water.
Every week, every 15 days, every month, if the appliance is not self-cleaning. At least once a year if the device can reverse polarity. There are no hard and fast rules. But, regardless of the characteristics of the swimming pool salt chlorinator, cleaning every 6 months is recommended.
Products To Descale The Salt Chlorinator Cell
The products used can be alcohol vinegar, hydrochloric acid or special anti-limescale products for swimming pools. Alcohol vinegar is slower but less dangerous than acid. It may be enough to solve the problem, plus it is environmentally friendly and economical! The higher the acidity of the vinegar, the faster the lime will be dissolved.
Hydrochloric acid acts faster but it pollutes (5 parts of water for one part acid). It is a dangerous product, to be handled with care. Protection such as gloves and goggles are essential, as well as covering your arms and legs.
How To Descale A Pool Chlorinator Cell
The part of the cell that will be cleaned is the part that contains the electrodes.
- Steps to follow:
- The electrode must be switched off.
- The water supply is cut off, for this it is necessary to close the 2 vertical bypass valves and all the water circulation valves to prevent the pump from being deactivated.
- The cell is removed from its housing, the cell’s electrical cable is disconnected, the connections unscrewed. A little water will spill out, it is the emptying of the cell and the junction pipes.
- The joints of the fitting are removed especially if acid is used! The cell is placed so that it can be filled with the descaling product.
- The vinegar, acid or anti-lime product is poured in, until the cell is submerged. With the acid, it is necessary to let act only a few minutes without rubbing or immersing the connection buttons.
- The process should be repeated until the electrodes are clean.
- When the cell is free of lime, it should be rinsed thoroughly.
If the descaling is done in season, the gaskets are replaced in the fittings, the cell is put back in place, the circulation valves and those of the bypass are reopened and the electricity is reconnected.
If the descaling is done during the winter while the water is at a temperature of 16 ° C, the by-pass valves must remain closed, the cell is stored in a frost-free place in the away from dust. If the pool water is at a temperature above 12 ° C, the water circulation valves are open and the pump is restarted. While waiting for the swimming pool to be completely winterized, a substitution treatment must be done.
