from the water softener for the purpose of pre-
venting corrosion.
When installing the water softener, select a loca-
tion where the unit can easily be connected to the
water supply network. A connection to the sew-
age system (at least DN 50), a floor drain and a
separate power supply (230 V / 50 Hz) must be
located in the immediate vicinity.
The emission of interference (voltage peaks, high-
frequency electromagnetic fields, interference
voltages, voltage fluctuations, etc.) by the sur-
rounding electrical systems may not exceed the
maximum values specified in EN 61000-6-4.
The rated mains power (230 V / 50 Hz) and the
required operating pressure must be present at
all times. A separate means of protection against
a shortage of water is not provided and must be
installed on site if desired.
If no floor drain and/or structural waterproofing
compliant with DIN 18195-5 is present, a sepa-
rate safety device (e.g. a hydrostop) must be
used.
The installation site must be protected against
frost and provide protection against chemicals,
paints, solvents, fumes and excessive ambient
temperatures.
If the softened water is intended for human con-
sumption as defined in the German Drinking Wa-
ter Ordinance ["Trinkwasserverordnung"], the
ambient temperature must not exceed 25°C.

The hose attached to the overflow of the brine
container and the flushing water hose must be
routed at an incline to the sewage system or con-
nected to a pump. Note:
1988, the flushing water and overflow hoses must
be connected at least 20 mm above the highest
possible waste water level (unimpeded drainage).
If flushing water is fed into a pump, it must be
designed for a water volume of at least 2 m
35 l/min. If the pump is used for other units con-
currently, it must be of a larger size to suit the
units' water output volumes.
The pump must be salt-water resistant.

- Non-compliance with the installation conditions
and the operator responsibilities voids the war-
ranty.
- The wearing parts defined in the "Operator re-
sponsibilities" section and the consequences
of failing to replace these parts on time are not
covered by the 2-year legal warranty.
- BWT assumes no liability in the event that the
unit fails or if the capacity becomes deficient
due to incorrect material selection/combination,
floating corrosion products or iron and manga-
nese deposits, or any resulting damage
thereof.
- The use of regenerative that does not comply
with DIN EN 973 type A voids the warranty.
