Our LIQUIPURE systems come standard inclusive two filter cartridges. The filter material (mixed bed resin) is blended with a color indicator. Fresh material is blue, but the color changes in the course of the use from blue to brown. When the resin is entirely brown the whole cartridge has to be replaced by a new one.

Cartridge change
Turn off the tap and open the filter housing with the help of the supplied spanner (big and white). Then take out the brown cartridge and dispose it via the household waste. Put the second cartridge in the place of the first one and finally, place a fresh cartridge onto the free position next to the water outlet.
