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 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-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 (230 V/50 Hz) and the required
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 de-
vice (e.g. a hydrostop) must be used.

The installation site must be frost-proof and kept free of
chemicals, paints, solvents and fumes, and the ambient
temperature must not be too high.

If the softened water is intended for human consump-
tion as defined in the Trinkwasserverordnung [Drinking
water ordinance], 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 connected to a pump. Note:

Note: In

accordance with DIN 1988, the flushing water and over-
flow hoses must be connected at least 20 mm above
the highest possible waste water level (unimpeded drain-
age).

If flushing water is fed into a pump, it must be designed
for a water quantity of at least 2 m

/h or 35 l/min.). If the

pump is used for other units concurrently, it must be
sized larger appropriate to the units’ water output quan-
tities.
The pump must be salt-water resistant.

-----

Non-compliance with the installation conditions
and the operator responsibilities voids the war-
ranty.

The wearing parts as outlined in the “O perator
responsibilities” 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/combina-
tion, floating corrosion products or iron and
manganese deposits, or any resulting damage
thereof.

The use of regenerative that does not comply
with DIN EN 973 type A voids the warranty.
