9. Installation
9.1
Mechanical installation
Softening Control must be installed in close proximity to the softening system to be moni-
tored. Installation is possible as wall or base frame mounted device with an installation space
of 300 x 300 x 150 mm (wide x height x depth), preferably at eye level. For installation at the
mounting area the mounting hole at the device case are to be used. Fitting accessories are to
be provided on site.
For sampling of raw and soft water branch pipes with preferable ¼” internal thread and pre-
filter of ≤ 0.1mm should be installed at the process inlet and process outlet of the softening
system. Further it must be pointed out that during operation the device must be provided per-
manently with a water pressure of minimum 1 bar up to 10 bars.
After selection of mounting area and pre-installation of mounting screws and electrical con-
nections by removing the back panel, the device can be installed easily.
9.2 Hydraulic installation
The hydraulic installation of inlets, outlet and hardness sensor is only to be carried out after
the unit has been fixed at the wall resp. frame as following:
1.
Push raw water hose Ø 4 mm ( blue hose ) as far as it will go into the pre-installed plug-in
connector “RW” outside of the casing
2. Push soft water hose Ø 4 mm ( black hose ) as far as it will go into the pre-installed plug-
in connector “SW” outside of the casing
Do not forget the prefilters!
3. Push the drainage tube Ø 6 mm tightly into the T-fitting at the outlet of the measurement
chamber
4. Plug the sensor socket of the sensor system into the electrical connection of the flow
measurement chamber at the device and fix it with the safety bolt
5. Push the analytical side of the sensor tightly into the T-fitting
Do not touch or damage the electrodes!
6. Open up streamed raw and soft water stop valve and check leak-tightness of the installed
raw and soft water hoses
The system is now subject to water pressure up to the closed valves RW and
WW.
7. If the pressure test is successful, the installation has been completed.
