3. USE AND DESIGN
The BWT MyAQUA Soft filter cartridge refines your tap water into best, filtered water in four
filtration stages (see Fig. 1).
1 Prefiltration filters out particles such as sand or rust.
2 Activated carbon pre-filtration reduces odour and taste disturbing substances such as
chlorine and protects the filter.
3
Ion exchanger reduces the total hardness of drinking water and thus protects appliances from
lime deposits. It reduces heavy metals such as copper, lead and nickel.
4 Fine filtration captures even the finest particles.
The BWT MyAQUA filter head A is fitted with an Aquastop, which prevents unintentional leakage
of water during filter installation.
Note:
The filtered drinking water corresponds to Liquid Category 2 in accordance with EN 1717.
The BWT MyAQUA filter head is only suitable for original BWT MyAQUA and BWT AQA drink
filter cartridges.
4. OPERATING AND SAFETY INSTRUCTIONS
» The BWT filter cartridge can only be used with cold water that meets the legal requirements
for drinking water quality.
» Comply with all country-specific installation regulations (e. g. DIN 1988, EN 1717), general
hygiene conditions and technical data relating to the protection of drinking water.
» Two non-return valves in accordance with DIN EN 13959 are integrated in the filter head.
» The installation location must be protected against frost and direct sunlight. Do not install
the unit near any sources of heat or open flame.
» The filter system must not come in contact with or be exposed to any chemicals, solvents
and vapours.
» The filter head must never be under water mains pressure for long periods without the filter
cartridge mounted in place.
» The filter head must be replaced after 5 years in service.
» The filter system can be operated in either a vertical or horizontal position:
- Vertical: Leave approx. 65 mm clearance above the ground to facilitate filter replacement.
- Horizontal: The filter cartridge must rest on the ground.
» If the filter system is used with a filter tap, a slight overrun may occur when the BWT MyAQUA
filter cartridge is put into operation. This subsides as soon as the filter cartridge is completely
vented, at the latest after a few days.
» If the authorities require tap water to be boiled, this requirement also applies to filtered water.
Once the drinking water supply has been approved again as harmless, the filter cartridge
must be replaced and all hoses and connections cleaned.
» For certain groups of people (e.g. immunocompromised persons, infants) it is recommended
to boil tap water before consumption. This also applies to filtered water.
» Breaks in operation:
- Lasting 2 days or longer: Rinse filter system with 3 litres of water
- Lasting 4 weeks or longer: Filter cartridge must be replaced
