8. Commissioning
8.1 Adjust softening
1. Measuring the water hardness with support from the
total hardness test-kit, included in the scope of deli-
very, the water hardness should be measured
before the installation.
2. Set the dilution unit with the blue adjustment handle
o The suitable dilution setting (marker 0-3 on the
casing of the dilution unit, remove insulation lining
if necessary) is dependant on the regional water
hardness and the desired residual hardness. The
value can be extracted from the table attached to
the cartridge.
8.2 Filling up the system
1. Slowly open the ball valve on the inlet and outlet
side of the blending unit
2. After filling up the system, close the ball valves
3. Note the required parameters listed on the label on
the cartridge
9. Maintenance
9.1 Maintenance
In accordance with DIN EN 1717 a regular mainte-
nance must be taken.
9.2 Replacing cartridge
1. Close the ball valve on the inlet and outlet side of the
blending unit
2. Decompress the outlet side by opening the
sampling valve (air bleed valve of the blending unit)
3. Unscrew the cartridge from the blending unit
4. Screw the new cartridge in manually
5. Open ball valves on the inlet and outlet side
10. Disposal
• Dezincification-resistant brass housing
• Mechanical components of the blending unit made
of high-quality synthetic material
• EPDM sealing washers
11. Troubleshooting
Observe the information in the instruction manual
of the total hardness test-kit
Maintenance, service and repair work may be
carried out only by authorised technicians.
We recommend a planned maintenance contract
with an installation company
Frequency: every 1-3 years (depending on local
operating conditions)
To be carried out by an installation company
When the filling level of the heating system
exceeds the specified capacity, a cartridge
exchange has to be performed.
The maximum capacity is determined according
to the total water hardness and the dilution
setting. (see table in chapter 14)
The capacity is noted on a table included in the
scope of delivery, as well as the respectively
added amounts of water. If the filling level
exceeds the noted water flow meter end value, a
cartridge exchange has to be performed.
An exchange of the softening cartridge is recom-
mended at least 12 months after its first usage
due to technical safety purposes.
Problem
Cause
Remedy
No or too small water flow rate Ball valves up- or downstream of refilling
combination are not fully open
Open ball valves entirely
