Function
The unit operates according to the principle of
intelligent regeneration.
Intelligent quantity-dependent regeneration:
When the unit is started, the available supply of
softened water is programmed (depending on the
hardness of the drinking water).
At a user-defined time (e.g. at night), the unit checks
whether the remaining supply of softened water is
sufficient for the following day.
If not, the softening column is regenerated in order
to refill the supply of softened water up to 100%.
In the event of a power failure, the data and the time
are kept (about 1 year).
The unit is equipped with a device that disinfects
the ion exchange resin during the regeneration.
Spring-loaded non-return valves protect all water
connections on the inlet side of the unit.
Automatic activation of regeneration:
If the capacity is not used up within four days, the
electronic system triggers a regeneration.
The system complies with all relevant national and
international standards.
Bewamat 75 A only:
Two capacity levels can be set on the controller,
making the unit suitable for larger applications.
The unit is preset. In case less performance
is necessary, this can be set by after-sales
service.

5.3
Site of installation and surround-
ing area
Water softeners must not be installed in water sup-
ply systems that provide water for fire extinguishing
purposes.
Make sure that the site of installation is frost-proof,
guarantees protection of the unit against chemicals,
dyes, solvents and vapours and enables easy con-
nection to the water supply.
Device must be installed immediately
downstream of an AS/NZS 2845.1 backflow
prevention valve! Please contact your plum-
ber!
Caution! Do not install or expose the product
to direct sunlight or UV!
A wastewater connection, a floor drain and a se
-
parate network connection (230 V/50 Hz) must be
close by. The power supply must be permanently
guaranteed.
If the treated water is exclusively for use in technical
applications, the ambient temperature must not
exceed 40 °C.
Separate protection against water deficiencies does
not exist and must be fitted locally – if required.
