Applicable standards for the filling facility:
(DIN) EN 1717 Protection against pollution of potable water installations
(DIN) EN 14367 Non controllable backflow preventer – Family C, type A
DIN 1988-100 (for Germany) Drinking water supply systems
For installation and operation, observe country-specific standards and directives.
Installation and operating information:
The filling facility contains a hydraulic separator CA (class b) to EN 14367.
According to 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 filling
facility. An (initial) filling with treated water (deionised water, etc.) corresponds to a higher hazard category, for which
the CA hydraulic 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 hand wheel and fill to about 2 bar system pressure (observe pressure indication
on pressure gauge or display module). After filling, close the hand wheel.
Maintenance:
The filling facility with CA hydraulic separator does not require any maintenance.
If there is water leaking from the CA hydraulic separator outlet, correct function can no longer be guaranteed and the
CA hydraulic separator should be replaced.
