Note:
With regard to the installation of water softeners with optional
accessories (refer to chapter C, 6.2), the operation manuals enclosed
with these accessories must be observed as well.
1.1 Water installation
Certain binding rules must definitely be observed when installing the
water softener Weichwassermeister
®
GSX. Additional recommenda-
tions facilitate the work with the water softener. The installation in-
structions described herein are summarised in Fig. D-1.
Binding rules
The installation of a water softener represents a major interference with
the drinking water system. Only authorised experts may install such sys-
tems.
Observe the local installation guidelines and the general
guidelines.
Downstream of the Weichwassermeister
®
GSX, a water tap has to be
provided close by others on site for the purpose of checking the soft
water quality.
The water softener must be preceded by a drinking water filter (e. g.
BOXER
®
KD incl. pressure reducer) and if necessary, by a pressure re-
ducer. Recommended pressure: 4 bar.
If the process (e. g. reverse osmosis system) established downstream
requires such, a system separator has to be installed.
Use corrosion-resistant material for the soft water pipe (e. g. stainless
steel, plastic, PE-X). In case of galvanised steel or copper, we recom-
mend dosing a corrosion inhibitor (refer to optional accessories: EXA-
DOS
®
dosing computer)
Note:
If required, the drain connection can be made at up to 1 m above
the water softener. However, in case of a high drain connection, the
connection of the overflow hose of the brine tank cannot be made (but
this safety feature is not necessarily required as a float valve is installed in
the brine tank as an initial safety measure).
Note:
Excerpt from DIN 1988 part 7 (4.2.2)
“… Comment:
In general the corrosion behaviour of copper pipes, gal-
vanised steel pipes and stainless steel pipes is not influenced by the sof-
tening process. However, when switching to softened water in galva-
nised steel pipes, the water may turn brownish, or in copper pipes it
may become greenish. A dosing unit … can counteract this effect.”
