Automatic triggering of regeneration process
If the capacity is not exhausted within 4 days, the
electronics trigger a regeneration cycle.
The system is characterised by its compliance with
all relevant national and international standards.
Electrical power failure
In the case of an electrical power failure of more
than 8 hours, the softener will restart with automatic
regeneration.
The pre-programmed parameters are perma-nently
stored and are not affected by a power outage.

5 Installation conditions
5.1 General
The unit must be installed as described in the in-
stallation 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.
Observe all applicable local installation regulations,
general guidelines, sanitary requirements and tech-
nical specifications.
5.2 Installation site and environment
Water softeners may not be installed in systems
that provide water for fire extinguishing purposes.
The installation site must be kept free of frost, must
protect the unit from chemicals, paint, solvents
and fumes, must be structurally waterproofed in
accordance with DIN 18195-5 and must allow for
easy connection to the water supply system.
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.
If there is no floor drain, the Aqua Stop safety func-
tion 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 softener
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.
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.
