1. General information
The HYDRO
ION
®
VAS
– CS softener is designed as Simplex system consisting of one resin vessel
(pressure vessel) with ion exchange resin and support quartz gravel as well as one control valve on
top of the filter vessel each. All operation modes are realized by means of a micro processor control.
The softener system HYDRO
ION®
VAS 25 is filled with exchange resin ex works. The system
up to “VAS 600” has to be filled with exchange resin in situ (chapter
IV
section 3.1).
The resin vessel for the HYDRO
ION
®
VAS range is dispatched empty for handling purposes
and must be filled with the gravel and ion exchange resin on site (see Chapter 6.5.1.). The resin
will be supplied separately in 25l bags.
It is the responsibility of the commissioning engineer to fill the resin vessel with the gravel and
resin. Hydrotec (UK) Ltd. will perform this service during commissioning visit.
Necessary pipe connections to the central control valve must be performed on site.
Softener is controlled via water flow meter installed in the soft water pipe.
The control settings are programmed in the microprocessor control unit.
Information and parameters such as time, regeneration status, residual capacity, water
consumption, operation days, functions and actual state for inputs and outputs are shown in the
display of the microprocessor control unit.
The brine container / salt bin which holds the tablet salt regenerant must be located immediately
adjacent to the resin vessel.
The supply of the regenerant to the control valve of the respective vessel is by float valve and
hose line into the vessel.
Wash water (waste water) is discharged to drain.
Incoming water is drinking water
According to standard EN1717 (DIN 1988), water softeners have to be provided with the
following safety fittings:
-
Black flow prevention device
Due to the installation of a back flow prevention device, the pipe work is protected against
the return of treated drinking water into the drinking water system.
Please consult local regulation.
-
Protective filter
Suited for the protection of the pipe installation and the softener against malfunction and
corrosion damage that can arise by foreign particles such as rust, sand etc.
According to standard DIN 13443-1, a filter has to be installed in the pipe before the system
separator and just after the water meter in case of metal pipe work.
The installation of a protective filter is recommended for plastic pipe work as well.
