Installation
The pipeline network must be flushed before the
unit can be installed.
You must check whether a mineral metering device
needs to be installed downstream from the water
softener for the purpose of preventing corrosion.
Use corrosion-resistant pipe materials for installati-
on. Pay attention to corrosion-causing chemical pro-
perties when different pipe materials are combined
(mixed installation), even in the inflow direction
upstream of the water softener.
A protective filter must be installed in the direction
of flow 1 m upstream of the unit. The filter must be
functional before the softener is installed. This is the
only way to ensure that dirt and corrosive products
do not enter the water softener.
Test sample extraction points must be installed
upstream and downstream of the unit, according
to the specifications of VDI 6023.
The hose attached to the overflow point of the
regenerative container and the flushing water hose
must be routed at an incline to the sewage system
or connected to a pump.
According to EN 1717, the flushing water hose and
the overflow hose must be connected to the sewage
system at a specified distance above the highest
possible waste water level. (Distance is greater than
the diameter of the drain pipe).
If the flushing water is fed into a p ump, it must be
designed for a water volume of at least 2 m
35 l/min for units for building services and at least
3 m
/h or 50 l/min for Rondomat and AQA perla

professional units.
If the pump is used for other units concurrently,
it must be of a larger size to suit the units' water
output volumes.
The pump must be salt-water resistant.
5.5
Operation
The performance specifications of the unit must
match the expected usage conditions. Related
information can be found in DIN 1988-200 and in
the technical specifications.
After periods in which little or no water is tapped,
e.g. during holidays, you must fully open the tap
for at least 5 minutes before you can use the water
again (see the section on stoppages in the operating
instructions).
The microbiological quality of the softened water is
also determined by the quality of the regenerative
used.

Prerequisite for function and
warranty
Softening plants or ion exchange plants require
regular function monitoring, maintenance and the
replacement of functionally relevant parts after
certain time intervals.
The required quantities of dosing and regenerating
agent are subject to consumption depending on the
operating conditions.
Softening systems must be cleaned and, if neces-
sary, disinfected regularly. The maintenance inter-
vals can be found in the installation and operating
instructions. We recommend the conclusion of a
maintenance contract.
