Installation Requirements
Observe all applicable installation regulations,
general guidelines, hygiene requirements and
technical specifications.
Water softeners may not be installed in water
supply systems that provide water for fire extin-
guishing purposes.
The pipeline network must be flushed before the
unit can be installed.
The hard water to be fed into the unit must always
meet the specifications of the German Drinking
Water Ordinance [“Trinkwasserverordnung”] or
EU Directive 98/83/EC. The total dissolved iron
and manganese may not exceed 0.1 mg/l. The
hard water to be fed into the unit must always be
free of air bubbles. If necessary, a exhauster must
be installed.
Continuous operation of the water softener with
water containing chlorine or chlorine dioxide is
possible if the concentration of free chlorine/chlo-
rine dioxide does not exceed 0.5 mg/l.
However, continuous operation with water con-
taining chlorine/chlorine dioxide causes the ion
exchange resin to age prematurely. A water sof-
tener reduces the concentration of free chlorine
and chlorine dioxide. In other words, the concen-
tration in the outflow of a water softener is gener-
ally considerably lower than in the inflow.
The unit should be sized in such a way that re-
generation is necessary at least once a day based
upon the throughput. If water consumption is re-
duced, e.g. during holidays, a shut-off device must
be fully opened for at least 5 minutes before wa-
ter can be used again (DIN 1988, parts 4 and 8).
Use corrosion-resistant pipe materials for instal-
lation. Pay attention to corrosion-causing chemi-
cal properties when different pipe materials are
combined (mixed installation), even in the direc-
tion of flow upstream of the water softener.
A protective filter must be installed in the direction
of flow no further than 1 m

1 m upstream from the
water softener. The filter must be functional be-
fore the water softener is installed. This is the
only way to ensure that dirt and corrosion prod-
ucts do not enter the water softener.

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 or-
der 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 (in com-
pliance with the German Technical and Scientific
Association for Gas and Water [DVGW).

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.

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.
