Abstract

A water-conditioning cartridge has a housing that encloses an ion exchanger and can be screwed via a screw thread onto a cartridge-connecting fitting. The cartridge is provided with a water inlet for admission of untreated water, especially from a water-supply system, and with a water outlet, which is connected or can be connected to a consuming component, especially a beverage machine. To ensure that the water-conditioning cartridge can be screwed onto only a particular cartridge-connecting fitting designed for this type of water-conditioning cartridge, the housing and the cartridge-connecting fitting are each provided with a plurality of annular coding ribs, which are disposed concentrically relative to the thread axis of the screw thread, and which engage with one another when the housing is screwed onto the cartridge-connecting fitting.
