When installing the unit, select a location where the unit
can easily be connected to the water supply network.
A connection to the sewage system (at least DN50), a
floor drain and a separate mains socket (230V/50Hz)
must be nearby.
The emission of interference (voltage peaks, high-fre-
quency electromagnetic fields, interference voltages,
voltage fluctuations, etc.) by the surrounding electrical
systems may not exceed the maximum values speci-
fied in EN 61000-6-4.
The rated mains power (230V/50Hz) and the requisite
operating pressure must be present at all times. A
separate means of protection against a lack of water is
not provided and must be installed on-site if required.
If no floor drain and/or structural waterproofing compli-
ant with DIN 18195-5 is present, a separate safety
device (e.g. a hydrostop) must be used.
The installation site must be free of frost and kept free
of chemicals, paint, solvents and fumes, and the ambi-
ent temperature must not be too high.
If the softened water is intended for human consump-
tion as defined in the German drinking water regula-
tions, the ambient temperature must not exceed 25°C.

The hose attached to the overflow of the brine con-
tainer and the flushing water hose must be routed at an
incline to the sewage system or connected to a pump.

Note: According to DIN 1988, the flushing water hose
must be secured at a distance of at least 20mm from
the highest possible waste water level (free discharge).
If flushing water is fed into a pump, it must be designed
for a water quantity of at least 2m3/h or 35 l/min.). If the
pump is used for other units simultaneously, it must be
sized larger by a factor of their water output quantities.
The pump must be salt-water resistant.

- Non-compliance with the installation condi-
tions and/or the operator responsibilities voids
the warranty.
- The wearing parts as outlined in the
“Operator Responsibilities” chapter and the
consequences of failing to replace these
parts on time is not covered by the 2-year
legal warranty.
- BWT does not assume responsibility if the
unit fails or if the capacity becomes deficient
due to incorrect material selection/combina-
tion, floating corrosive products or iron and
mineral deposits, or any resulting damage
thereof.
- Using regenerative that does not comply with
DIN EN 973 type A voids the warranty.
