Applicablestandardsforthellingfacility:
(DIN) EN 1717 Protection against pollution of potable water installations
(DIN)EN14367Noncontrollablebackowpreventer-FamilyC,typeA
DIN 1988-100 (for Germany) Codes of practice for drinking water installations
Alsoobservethecountry-specicstandardsandguidelinesoninstallationandoperation.
Installationandoperatinginformation:
ThellingfacilitycontainsahydraulicseparatorCA(classb)toDINEN14367.
According to DIN EN 1717, hydraulic 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)llingoftheheatingsystemusingthelling
facility.An(initial)lling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llingfacility,werecommendusingadirttrap(nelter)inthe
DHW installation.
Operation:
Forthellingprocedure,openthehandwheelandlltoabout2barsystempressure(observepressureindication
onpressuregaugeordisplaymodule).Afterlling,closethehandwheel.

Maintenance:
Thelling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.
