4.3 Replacing a lter cartridge
Once 90 % of the lter capacity has been used up, at the latest after 360 days, you are prompted to re-
place the lter cartridge:
⇒ Run the ushing hose into a suitable container (e.g., a bucket) or into a drain.
⇒ Slowly unscrew the used lter cartridge anti-clockwise. This releases it from the lter head and it can be
removed.
♦ During this procedure, the consumer unit and the water supply line are hydraulically disconnected
from the lter head and the system is decompressed. In this case, it can happen that a minimal quan-
tity of decompression water can escape from the ushing hose due to pressure peaks. Take this into
consideration and place a suitable container underneath.
⇒ Open the purge valve (5) (OPEN, Fig. 3).

⇒ Close the purge valve (5) (CLOSE, Fig. 4).
⇒ Enter the date of installation and the time of replacement in the corresponding elds on the sticker on
the lter cartridge (a ballpoint pen can be used).

If the lter cartridge is removed from the lter head without being replaced by a new one, the wa-
ter supply to the lter head must be shut o󰀨.
4.3.1 Resetting the counter / checking the lter capacity
If a lter cartridge of the same size was used when replacing the lter cartridge, only the counter needs to
be reset.
If a larger lter cartridge is used, its capacity must be entered rst.
