Replacing the lter cartridge
New lter cartridges are available under type number WP3911.
Replace the lter cartridge if it is clogged to prevent damage to the
water purier.
No part of the cartridge can be reused. Discard the used cartridge and
replace it with a new one.
When to replace the lter cartridge
The actual lifetime of the lter cartridge depends on the quality of the
local water and the water pressure. For optimal performance of the
water purier, replace the lter cartridge if one of the following situations
occurs:
The display shows that the remaining lter capacity is 0 litres and
keeps ashing.
The hollow bre of the lter cartridge (visible through the cartridge
window) has turned rust brown or dark grey (see section ‘Cartridge
replacement indicator’).
You have used the lter cartridge for 6 months.
The volume of puried water decreases substantially.
The ltered water still has an unpleasant smell or is still turbid
after purication.
Cartridge replacement indicator
To help you determine when to replace the lter cartridge, the water
purier and each replacement lter 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 lter cartridge and stick the cartridge
replacement indicator to the inside of the cover. Check the colour of the
hollow bre of the lter cartridge through the cartridge window from time to
time. If the colour of the lter matches the rust brown or dark grey shown on
the cartridge replacement indicator, replace the lter cartridge (Fig. 28).
