5 Installation conditions

1 General
1.1 The unit must be installed as described in the
installation instructions and in compliance with
AVB Wasser V, §12.2 (general requirements
for the supply of water in Germany). It must be
installed by a water utility company or by an
installation company registered in the water
utility company's index of installers.
1.2 Observe all applicable local installation regu-
lations, general guidelines, sanitary require-
ments and technical specifications.
2 Installation site and environment
2.1 Water softeners may not be installed in sys-
tems that provide water for fire extinguishing
purposes.
2.2 The installation site must be kept free of frost,
must protect the unit from chemicals, paint,
solvents and fumes, must be structurally wa-
terproofed in accordance with DIN 18195-5
and must allow for easy connection to the
water supply system.
2.3 A connection to the sewage system, a floor
drain and a separate mains connection (230
V/50 Hz) must be located in the immediate
vicinity.
2.4 If there is no floor drain, the Aqua Stop sa-
fety function integrated in the water softener
(available with some models) or the internal
Aqua Stop function may suffice.
However, this is at the property insurer's
discretion. It is the unit operator's responsibility
to clarify this.
If there is no floor drain and the water softe-
ner does not have an integrated Aqua Stop
function, a separate safety device will have
to be installed on site in the direction of flow
upstream of the softener.
This safety device (e.g. BWT Aqua Stop) has
to shut off the water supply when there is no
current in order to prevent unintended water
leakage from the water softener when the unit
is damaged.
2.5 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.
3 Feed water
3.1 The hard water to be fed into the unit
must always meet the specifications of
the Trinkwasserverordnung (German drin-
king water ordinance) or EU Directi-
ve 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 necessary.
3.2 If the treated water is intended for human con-
sumption as defined in the Trinkwasser-verord-
nung (German drinking water ordinance), the
ambient temperature must not exceed 25°C.
If the treated water is intended for industrial
purposes only, the ambient temperature must
not exceed 40 °C.
3.3 The unit's maximum operating pressure must
never be exceeded (see technical specifi-
cations). If the network pressure is higher, a
pressure reducer must be installed upstream
of the unit.
The unit requires a minimum operating pressu-
re to function (see 12 Technical specifications).
During pressure fluctuations and surges, the
sum of the pressure surge and the standing
pressure must not exceed the nominal pres-
sure. The positive pressure surge must not
exceed 2 bar and the negative pressure surge
must not be less than 50% of the self-adjusting
flow pressure (see DIN 1988-200/3.4.3).
3.4 Continuous operation of the water softener
with water containing chlorine or chlorine dioxi-
de is possible if the concentration of free chlo-
rine/chlorine dioxide does not exceed 0.5 mg/l.
Continuous operation with water containing
chlorine/chlorine dioxide will cause premature
ageing of the ion exchange material. A water
softener reduces the concentration of free
chlorine and chlorine dioxide. In other words,
the concentration in the outflow of a water
softener is generally considerably lower than
in the inflow.
4 Installation
4.1 The pipeline network must be flushed before
the unit can be installed.
