To prolong the service life of the membrane, it has to be descaled periodically. When you notice that the flow rate from the tap has decreased, you need to follow the descaling procedure below. The time schedule for how often you will need to do this will depend on your particular water supply, especially on its levels of calcium ("hardness", see table, right), iron, manganese and possibly silicon, as well as of microorganisms. Even with regular descaling, the maximum flow of purified water from the appliance will decrease gradually on account of the normal properties of the membrane. When you notice that the flow is about half of what it was when the membrane was new, contact your dealer to have the membrane replaced. It takes about ten hours, during which time you will not be able to use the appliance. [. . . ] The adjusting screw in the tap may need adjustment, or washers in the tap may be damaged. · Check all connections. · Check that both ends of the hose for purified water are cut straight and clean, and not deformed.
