Applicable standards for filling facility with system separation
(DIN) EN 1717 Protection against pollution of potable water installations
(DIN) EN 14367 Non controllable backflow preventer - Family C, type A
Also observe the country-specific standards and guidelines on installation and operation.
Installation and operating information:
The filling facility contains a system separator CA (class b) to DIN EN 14367.
According to DIN EN 1717, system separators of type CA are approved for liquids up to and including hazard
category 3 (e.g. heating water without inhibitors).
For Germany and Austria, only drinking water may be used for the (initial) filling of the heating system using the fill-
ing facility with system separator. An (initial) filling with treated water (deionised water, etc.) corresponds to a higher
hazard category, for which the CA system separator may not be used.
To ensure long-term and fault-free operation of the filling facility, we recommend using a dirt trap (fine filter) in the
DHW installation.
Operation:
For the filling procedure, open the fill valve and fill to about 2 bar system pressure (observe pressure indication on
control unit display). After filling, close the fill valve.
Maintenance:
The filling facility with CA system separator does not require any maintenance.
If there is water leaking from the CA system separator outlet, correct function can no longer be guaranteed and the
CA system separator should be replaced.
