Replacing the filter cartridge

New filter cartridges are available under type number WP3911.
Replace the filter cartridge if it is clogged to prevent damage to the
water purifier.
No part of the cartridge can be reused. Discard the used cartridge and
replace it with a new one.

When to replace the filter cartridge

The actual lifetime of the filter cartridge depends on the quality of the
local water and the water pressure. For optimal performance of the
water purifier, replace the filter cartridge if one of the following situations
occurs:
- The display shows that the remaining filter capacity is 0 litres and
keeps flashing.
- The hollow fibre of the filter cartridge (visible through the cartridge
window) has turned rust brown or dark grey (see section 'Cartridge
replacement indicator').
- You have used the filter cartridge for 6 months.
- The volume of purified water decreases substantially.
- The filtered water still has an unpleasant smell or is still turbid
after purification.

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. 28).
