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 water supply, the Hydro Shield filter system must
be disconnected from the water supply. Flush the water pipe thoroughly before reconnecting
the Hydro Shield system.
I
CAUTION!
f Improper installation of the Hydro Shield 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 Hydro Shield system and technical modifications are not
permitted.
f Mechanical damage to the Hydro Shield system will invalidate the warranty.
f Install a valve upstream of the Hydro Shield system.
f Use only connections with gaskets. Conical seals damage the filter head connections and will
invalidate the warranty claim.
f The Hydro Shield system may only be connected using hoses in accordance with DVGW W 543.
f If the cartridge 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 Hydro Shield system near heat sources or open flames.
f Chemicals, solvents and vapours must not come into contact with the Hydro Shield system.
f The installation location must be frost-resistant and protected against direct sunlight.
INFORMATION!
f For installation and operation of the Hydro Shield system, the BG regulation "Rules for Safety
and Health Protection When Working in Kitchens" of the "Food and Beverages" expert com-
mittee of BGZ (BGR111) must be observed. The Hydro Shield system has been hygiene tested
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 combi steamer, bake off oven or other appliance before installing the
Hydro Shield system if the oven is not brand new.
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 Hydro Shield 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.
