Three capacity levels can be set on the control-
ler, making the unit suitable for up to four residen-
tial units.
The unit is preset. The presetting is appropriate
for the most common applications. It is neces-
sary to adjust the unit if there are special require-
ments.
The unit operates according to the principle of
intelligent 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 this is not the case, the softening column is
regenerated by only the exact percentage nec-
essary to fully replenish the supply of softened
water to 100%.
With intelligent regeneration, no remaining supply
of softened water is discarded.
This intelligent regeneration method is only pos-
sible because of the precision flowmeter, which is
able to allocate the low quantities of brine required
for partial regeneration.
The consumption of regenerative and water is
reduced to the technically required minimum.
In the event of a power failure, the data and the
time are retained (approx. 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 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.

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. Install a bleed device if neces-
sary.
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 softening unit.
A protective filter must be installed in the direction
of flow no further than 1 m
softening unit. The filter must be functional before
the softening unit is installed. This is the only way
to ensure that dirt and corrosive products do not
enter the water softener.
