8. Assembly
8.1 Installations Guidelines
• All works should only be carried out by a qualified
person
• Ensure that installation is not subject to freezing or
extreme heat
o Avoid direct exposure to sunlight.
• The softening device should rest on an even
surface.
• If the input pressure is more than 5 bar, then a pres-
sure reducer needs to be installed ahead of the
softening device according to DIN 1988.
• It should be checked whether a dosing device to
prevent corrosion should be added to the plant.
• A filter (e.g. F762) should be installed no more than
1 metre ahead in flow direction of the softening
device to protect the plant.
• The following is needed for operation in the close
vicinity of the device:
o a channel interface (at least DN50)
o separate mains connection (230 V / 50 Hz)
o Floor drain
8.2 Assembly instructions
To avoid irreplaceable damages on the softening
device, all welding and soldering work in the near
vicinity should be completed before the moun-
ting.
1. Thoroughly flush pipework
2. Install softening device
• Note flow direction (indicated by arrow)
• Install without tension or bending stresses
3. Establish the connections to the softening device
4. Connect the sewerage tube to the discharge
connection (inner tube ø min. 13 mm, 1/2")
Make sure the seal is fitted properly!

• The rinse water hose and the hose on the
safety overflow of the brine tank need to be laid
out with a decline towards the channel or fed
into a pumping station.
• The rinse water hose and the hose on the
safety overflow of the brine tank need to be
mounted acc. to DIN 1988 with at least 20 mm
distance (free outflow) to the highest possible
drainage water level.
• The pumping station needs to be constructed
for a water amount of at least 2 m³/h or 35l/min
and be salt-water proof. The pumping station
needs to have a greater capacity accordingly if
it is used for other plants as well.
8.3 Complying with the limit for the sodium
concentration
When operating a softening device, the limit value for
the sodium concentration (acc. drinking water ordi-
nance) of 200 mg/l may not be exceeded.
To reduce the water hardness by 1°dH, about 8mg/l
sodium needs to be added to the water. Additionally,
the basic sodium content* of the raw water needs to be
taken into account.
The maximum possible softening results from these
values.
Example:
Basic sodium content*Na

Result: the raw water hardness can be reduced
by 23.75 °dH.

9. Commissioning
1. Put diluting device into bypass position
o close the two outer valves
o open the middle valve
2. Open shut-off valve on inlet
3. Put diluting device into operating position
o Slowly open the input valve completely
o Slowly open the output valve completely
o Close middle valve
4. Check that the water connections do not leak
5. Pour water (about 1 litre) into the salt supply
