5 Installation conditions
5 1 General
The product must be installed as described in the
installation guide in compliance with the general
requirements for the supply of water in Germany
[“AVB Wasser”] V, section 12.2 by a water supply
company or by a party registered in the water supply
company’s index of fitters.
Observe all applicable local installation regulations,
general guidelines, sanitary requirements and tech-
nical specifications.
5 2 Installation locations and
environment
Softening units may not be installed in systems
that provide water for fire extinguishing purposes.
The installation location must meet the following
criteria:
● Protected against frost, chemicals, dyes, solvents
and fumes.
● Structurally waterproofed.
● Easy to connect to the water supply system.
● Sufficient clearance to open the technology
cover. (For minimum clearance, see chapter
“17.1 Dimensions”, page 75; the clearance
should be greater to allow for convenient refilling
of regenerative).
NOTE
► A sewage system connection, floor
drain and separate power supply must
be available in the immediate vicinity. For
power supply data, see chapter “17 Tech-
nical data”, page 74.
If there is no floor drain and the softening unit does
not have an integrated AQA Stop function, a sepa-
rate safety device will have to be installed on site in
the direction of flow upstream of the softening unit.
This safety device (e.g. external AQA Stop) has to
shut off the water supply when there is no current in
order to prevent unintended water leakage from the
softening unit if the product is damaged.
The rated mains power and the requisite operating
pressure must be present at all times. For data, see
chapter “17 Technical data”, page 74. A separate
means of protection against a shortage of water is
not provided and must be installed on site if desired.
5 2 1 Installation conditions with pump
If the flushing water is fed into a pump, the pump
must be appropriately equipped and sized:
● The pump must be resistant to salt water.
● Flow rate at least 2 m
3
/h or 35 l/min for products
for building services.
● Flow rate at least 3 m
3
/h or 50 l/min for products
in the Rondomat and BWT Perla Professional
series.
● Appropriate larger sizing if the pump is used
simultaneously for other products.
5 2 2 Reception conditions at the
installation location
In order to benefit from the connectivity of the prod -
uct, either GSM reception or integration into a home
network via LAN or Wi-Fi should be possible at the
installation location (see chapter “9 Connection”,
page 28).
5 3 Inflow water
The inflow water must always meet the specifi -
cations of the Trinkwasserverordnung (German
Drinking Water Ordinance) or EU directive 98/83/
EC. The total dissolved iron and manganese must
not exceed 0.1 mg/l. The inflow water must always
be free of air bubbles. Install a bleed device if
necessary.
If the treated water is intended for human con-
sumption as defined in the Trinkwasserverordnung
(German Drinking Water Ordinance), the ambient
temperature must not exceed 25 °C.
If the treated water is intended for industrial pur-
poses only, the ambient temperature must not
exceed 40 °C.
The product’s maximum operating pressure must
never be exceeded (see chapter “17 Technical
data”, page 74). If the network pressure is higher,
a pressure reducer must be installed upstream of
the product.
The product requires a minimum operating pressure
to function correctly (see chapter “17 Technical
data”, page 74).
The optimal operating pressure is between 3 and
6 bar.
