CAUTION!
f Observe all national directives for drinking water installations (e.g. DIN 1988, EN 1717) and applicable state and local regulations, general
sanitary requirements and technical data for the protection of drinking water.
f A check (shut-off) 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 and will invalidate the warranty claim.
f 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 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, open fire places or naked flames.
f Chemicals, solvents and vapours must not come into contact with the filter system.
f The installation location must be protected against freezing and direct sunlight.
NOTE!
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 hygiene tested in accor-
dance with Section 7.4 DIN 18879-1.
f 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 firstly installing the filter system.
f For immunocompromised people and infants it is recommended to boil the tap water before drinking. This also applies to filtered water.
f For the protection against microbiological growth the filter cartridge contains a small amount of silver ("bacteriostatic")*. There might
be a harmless release of silver in concentrations below the recommendations of the World Health Organization (WHO). The term
"bacterio static" 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.
f During the filtering process, the magnesium content rises slightly. If a special low-magnesium diet is to be followed, BWT recommends
to seek medical advice.
4.1
Responsibility of the operator
The installation and operating instructions must be kept in the immediate vicinity of the filter
system and must be accessible at any time.
The filter system may only be operated in a technically perfect state ensuring a safe
operation.
The instructions in this installation and operating manual must be followed entirely.
4.2 Warranty and exclusion of liability
BWT warrants to the original purchaser/consumer all equipment that it munufactures to be free
from defects in material and workmanship for a period of 2 years from the date of purchase. This
warranty is subject to exclusions and limitations
The notes and recommendations listed, as well as local drinking water and recycling regulations,
must be met. All information and notes in this installation and operating manual account for
the applicable standards and regulations, state-of-the-art technology as well as our expertise
in water treatment. BWT does not assume any liability for damages or subsequent/secondary
damages arising from:
Failure to comply with the instructions in this installation and operating manual

4.3 Qualified personnel
Only authorised, trained persons and professionals shall install, commission and maintain the
filter system.
Authorised, trained persons have obtained instructions regarding the assigned tasks and
possible risks in case of misuse or improper operation.
Professionals are in a position to install, commission and maintain the device, as a result
of their technical training, knowledge and experience, as well as knowledge of applicable
regulations.
4.4 Pressure
I
CAUTION!
f If the maximum nominal pressure exceeds 8 bar (116 psi) a pressure reducer must be installed upstream of the filter system.
NOTE!
f Installing a pressure reducer can reduce the flow.
f The inlet pressure of the filter system should be higher than 1.2 bar (17.4 psi).
Pressure surges are to be avoided. If they do occur, the sum of pressure surge and idling
pressure must not exceed the nominal pressure of 8 bar (116 psi). The positive pressure surge
must not exceed 2 bar (29 psi) and the negative pressure shock must not fall below 50% of the
settling flow pressure (see DIN 1988 Part 2.2.4).
4.5 Operation after a break or shutdown / Replacement intervals
In the event of longer breaks in operation, close the shut-off valve in the inlet of the filter system.
After a break in operation exceeding two days (weekends, vacation, ...), rinse the filter system
with 4-5 litres (1.1-1.3 gallons) of water before reuse.
Replace the filter cartridge ...
on reaching the capacity stated in Section 3.2.
no later than 6 months after installation.
after a shutdown of 4 weeks or more.
4.6 Disposal
Dispose of exhausted filter cartridges, surplus parts and packaging according to local
regulations. If local collection points are available, recycle all product components to protect the
environment.
5 Installing the filter system
NOTE!
f Decarbonized water contains free carbonic acid. Only appropiate materials are to be used for installation. Original BWT accessoiries are
recommended.
5.1
Unpacking the filter system
Remove the filter system from the packaging. Inspect the delivery for completeness and
transport damage. Defective parts must be replaced immediately.
I
CAUTION!
f Faulty or defect parts must be replaced immediately.
f Always ensure a safe and clean working environment.
