f To protect the drinking water, the national directives for drinking water installations
(e.g. DIN 1988, EN 1717) must be observed during all work on the filter system.
f If you are asked by the relevant authorities to boil the tap water because it is contaminated by
microbes, this applies to the filtered water too. If the authorities later state that the water is
safe to drink, the filter system must be replaced and the connections cleaned. Improper use can
cause damage to your health.
f A type-tested non-return valve in accordance with DIN EN 13959 is integrated into the filter head.
If large kitchen appliances, which due to their contamination potential (e.g. cleaning chemicals)
require a higher level of protection against backflow, are connected downstream of the filter
system, the appropriate safety devices must be integrated into the large kitchen appliance.
f Before carrying out maintenance work on the drinking water supply, the filter system must be
disconnected from the water supply. Flush the water pipe thoroughly before reconnecting the
filter system.
f The power supply to the end appliance must be disconnected (remove mains plug) prior to
installation.
I
CAUTION!
f Improper installation of the filter system can cause property damage. Observe the national
installation regulations (e.g. DIN 1988, EN 1717), general hygiene conditions and technical
data for the protection of the drinking water.
f Unauthorised alterations to the filter system and technical modifications are not permitted.
f Mechanical damage to the filter system will invalidate the warranty.
f Install a check valve upstream of the filter system.
f Use only connections with gaskets. Conical seals damage the filter head connections and will
invalidate the warranty claim.
f The appliance may only be connected using hoses in accordance with DVGW W 543.
f If the product has been stored below 0 °C, leave the unpacked product at the ambient
temperature of the installation location for a minimum of 24 hours prior to operation.
f Do not install the filter system near heat sources or naked flames.
f Chemicals, solvents and vapours must not come into contact with the filter.
f The installation location must be frost-resistant and protected against direct sunlight.

INFORMATION!
f For installation and operation of the filter system, the BG regulation "Rules for Safety and Health
Protection When Working in Kitchens" of the "Food and Beverages" expert committee of BGZ
(BGR111) must be observed. The filter system has been hygienetested in accordance with
Section 7.4 DIN 18879-1. The materials are selected in accordance with the requirements of
DIN 18879-1 and EN 14898. The pressure resistance of the filter system conforms to
DIN 18879-1.
f A type-tested non-return valve in accordance with DIN EN 13959 is integrated into the filter head.
f The filtered drinking water conforms to liquid category 2 in accordance with EN 1717.
f Clean and descale the appliance, e.g. coffee machine, before installing the water filter
system for the first time.
f For certain groups of people, such as babies and those with reduced immunity, it is re-
commended to boil the tap water before drinking. This also applies to filtered water.
f The filter contains small amounts of silver to suppress microbial growth. A small amount of silver
may be added to the water. This is perfectly safe and complies with the relevant re-
commendations of the World Health Organisation (WHO).
f During the filtering process, the sodium content rises slightly. If a special low-sodium diet is to be
followed, we recommend that you contact your doctor.
