I WARNING!
Any use contrary to the intended use, e.g., if the filter system is fed with water that is not of
f
drinking water quality, results in a health hazard when the water is drunk:
­ Microbiological hazard due to contamination with pathogenic germs
­ Hazard from too high a concentration of heavy metals or organic contamination
To protect the drinking water, maintenance and any other work on the filter system has to be carried
f
out considering national directives for drinking water installations (e.g. DIN 1988, EN 1717) and
applicable state and local regulations.
If the authorities or the operator of the water supply system release instructions to boil the potable
f
water due to microbial contamination it is necessary to boil the filtered water before consumption. If
the drinking water quality is restored the filter system must be replaced and connections cleaned.
Two type-tested non-return valves (in accordance with DIN EN 13959) are included in the filter
f
head. Large kitchen appliances may require a higher level of protection against backflow due to
their contamination potential (e.g. cleaning chemicals). If such appliances are connected down­
stream of the filter system, the appropriate safety devices must be integrated into the large kitchen
appliance.
Separate the filter system from the water supply prior to maintenance work on the drinking water
f
supply. Rinse the water line before reconnecting the filter system.
Disconnect the power supply of the appliance prior to installation.
f
I CAUTION!
Observe all national directives for drinking water installations (e.g. DIN 1988, EN 1717) and
f
applicable state and local regulations, general sanitary requirements and technical data for the
protection of drinking water.
A check (shut­off) valve upstream of the filter system must be installed.
f
Use only connections with gaskets or flat seals. Conical seals damage the filter head connections
f
and will invalidate the warranty claim.
The appliance needs to be connected with hoses in accordance with DVGW W 543 or NSF 42/53.
f
If the product has been stored below freezing point (0°C), leave the unpacked product at the
f
ambient temperature of the installation location for a minimum of 24 hours prior to operation.
Do not install the filter system near heat sources, open fire places or naked flames.
f
Chemicals, solvents and vapours must not come into contact with the filter system.
f
Unauthorised alterations to the filter system and technical modifications are not permitted.
f
The installation location must be protected against freezing and direct sunlight.
f
NOTE!*

For installation and operation of the filter system, the BG regulation "Rules for Safety and Health
f
Protection When Working in Kitchens" of the "Food and Beverages" expert committee of BGZ
(BGR111) must be observed. The filter 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.
f
The pressure resistance of the filter system conforms to DIN 18879-1.
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 initial installation of the filter system.
f
For immunocompromised people and infants it is recommended to boil the tap water before
f
drinking. This also applies to filtered water.
For the protection against microbiological growth the filter cartridge contains a small amount of
f
silver ("bacteriostatic")*. There might be a harmless release of silver in concentrations below the
recommendations of the World Health Organization (WHO). The term "bacteriostatic" indicates that
the system limits the passage or growth of bacteria already existing in the incoming water*. It does
not mean that the water leaving the system is safer to drink than the water entering it.
During the filtering process, the sodium content rises slightly. If a special low­sodium diet is to be
f
followed, BWT recommends to seek medical advice.
