3. Intended use 4. Efciency of the lter cartridge
The BWT water ltering system may only be operated with cold water
fullling the legal requirements made on potable water quality.
The water lter is unsuitable for the production of potable water; i. e. the
lter may not be used for treatment of contaminated water.
The BWT ltered water is intended for short-term use. It may not be exposed
to direct radiation of the sun, is to be stored in a cool place and not longer
than 24 hours. If the ltered water is kept longer than 24 hours in the water
ltering system, white marks may occur in the jug through the evaporation
of water, which can easily be removed through cleaning.
After ltering more than 3 litres subsequently, a pause of at least 15
minutes should be made.
Permanent water contact of the lter cartridge is not particularly necessary,
in order to guaranty long-term operation of the lter cartridge. The lter cart-
ridge continues to function, also if it was taken out of the water for some time.
If from the ofcial side you are requested, to boil the tap water due to
contamination with germs, this also applies to BWT ltered water. When
the authorities classify the tap water again as harmless and release it for
consumption, the lter cartridge must in any case be changed. The water
ltering system is to be cleaned (see chapter 6.1 and 8).
For certain groups of people, e.g. persons with limited immune defence and
for the preparation of baby food, the BWT ltered water is to be boiled.
For hygienic reasons the lter cartridge contains small quantities of silver, in
order to suppress the growth of germs. A small quantity of silver may be given
off to the water. It is harmless and in compliance with the corresponding re-
commendations of the World Health Organization (WHO) for potable water.
The lter cartridge shall be replaced at least 4 weeks after its rst use.
Appliance for the treatment of drinking water.
Important: this appliance requires regular periodic maintenance in order to
guarantee the requisites of the drinkability of the water treated and that the
improvements as declared by the manufacturer are maintained.
The service life of the lter cartridge varies according to the place of applica-
tion, as the quality of water is not everywhere the same. The capacity of the
lter cartridge compared to the retained hardness depends on the hardness of
the water. The harder the water, the earlier the lter cartridge will be exhausted.

The mentioned substances, e.g. lead and copper, which are reduced by the
lter, are not always contained in potable water.
The water lter fulls the microbiological requirements made on water lters
according to DIN 10521. The requirements according to DIN 10521 made on
chlorine, lead and copper retention are fullled.
