Application
®
The GROHE Blue Mg 2+ filter cartridge reduces total
hardness and filters out heavy metals such as lead and
copper. Furthermore calcium ions would be changed against
magnesium ions and additionally drinking water will be
enriched with magnesium. The magnesium enrichment
depends on the water hardness of the water.
Moreover, clouding and organic contamination, as well as
substances which impair odour and taste (chlorine), are
reduced. Furthermore, the filter material captures particles
such as sand and suspended solids.
The water filtrate is classified as Category 2 according
to EN 1717.
Safety notes
• The filter system may only be operated with cold water of
foodstuff grade.
• The filter head is equipped with a non-return valve according
to EN 13959.
• At the installation location, the filter system must be
protected against mechanical damage, heat and direct
sunlight.
Do not install near heat sources or an open fire.
• Following storage and transport at temperatures below 0 °C,
a replacement filter cartridge must be stored in its opened
original packaging at ambient temperatures of 4 – 40 °C for
at least 24 hours before use.
• The maximum shelf life of a replacement filter cartridge in its
unopened packaging is 2 years.
• The filter head must be replaced after 5 years.
• The filter system must be put out of service if an official
boilwater notice is issued, e.g. by the water supplier. The
filter cartridge must be changed once the boil-water notice
is lifted.
• It is generally recommended to boil tap water for certain
groups of people (e.g. immuno-compromised people,
babies). This also applies to filtered water.
• Filtered water is a foodstuff and must be used
within 1 – 2 days.
• GROHE recommends not leaving the filter system out of
service for extended periods of time. If the GROHE Blue
filter system is not used for 2 – 3 days, at least 4 – 5 litres
®
of GROHE Blue water must be drawn off and discarded.
®
If the GROHE Blue filter system is not used for more
than 4 weeks the filter cartridge must be changed.

During commissioning and when changing the filter,
cleanliness and hygiene must be observed!
The filter system must be flushed each time the filter is
changed.
®
- Open Blue handle and draw off and discard at
least 4 – 5 litres of water.
Setting the filter size, see technical product information for
the cooler or the control unit.
For use of the Mg 2+ filter cartridge, the control unit of the
®
GROHE Blue system must be set to F7.
Setting the total hardness, see technical product information
for the cooler or the control unit.
The relevant water supplier can provide information on the
total hardness.
