During normal operation a white calcium residue will build up on the plates of the electrolytic cell within your salt generator. The cell operates most efficiently when the cell is clean so the manufacturers recommend cleaning these cell at least once a year. This guide describes how to dismantel and clean a Compupool cell. Note: some cells such as this Compupool cell have an auto cell cleaning process that significantly reduces a calcium buildup. This in turn reduces the need to clean the cell as often. Under normal conditions, a cell should be replaced after 12,500 hours of use.
Generally the Cell can be extracted from the Cell Assembly without removing the Cell Assembly from the piping. If, however, your work space is tight and you have to remove the Cell Assembly, loosen the barrel unions that connect the Cell Assembly to the piping and lift the Cell Assembly off the piping. Check the O-rings for wear and replace is required.
