1 For optimal performance of the water purifier, replace the filter
cartridge if either of the following situations occurs:
a You have used the filter cartridge for six months.
B The hollow fibre of the filter cartridge (visible through the cartridge
window) has turned rust brown or dark grey (see section 'Cartridge
replacement indicator').
C The volume of purified water decreases substantially.
D The filtered water still has an unpleasant smell or is still turbid
after purification.
 To change the filter, close the tap and set the water selection lever
to the unfiltered stream position. (Fig. 22)
 Tilt the used filter cartridge 90° backwards and pull it off the water
purifier housing (Fig. 23).
 Write down the replacement date on the information label of the
new cartridge.
5 Tilt the new filter cartridge 90° backwards and insert it into the
water purifier housing.
6 Pull the cartridge upwards until it is in upright position. (Fig. 24)
Cartridge replacement indicator
To help you determine when to replace the filter cartridge, the water
purifier and each replacement filter cartridge comes with a self-adhesive
colour-coded cartridge replacement indicator. Place this replacement
indicator in a convenient place for future reference.
Tip: Remove the cover of the filter cartridge and stick the cartridge
replacement indicator to the inside of the cover. Check the colour of the
hollow fibre of the filter cartridge through the cartridge window from time to
time. If the colour of the filter matches the rust brown or dark grey shown on
the cartridge replacement indicator, replace the filter cartridge (Fig. 27).
