8.3 System Separator for Fresh Water:
Servicing
The regular servicing of the System Separator BA is obligatory.
Accordingly, service contracts between the operating company and the installer make sense. The checking of the correct and
proper functioning of the valves takes place after the first year of operation, then at intervals dependent on the operating
conditions, but after one year at the latest. The ball valve connections present in each pressure zone enable a functional
check using an appropriate pressure measurement device (Service Case No. 6600.00.902). The design of the system
separator with a cartridge system allows simple and problem-free servicing of the valves.

Function Description:
System separators of the type BA are divided in 3 pressure zones. In Zone (1)
the pressure is higher than that in Zone (2) and there higher than that in Zone
(3). A discharge valve is connected to Zone (2) which opens at the latest when
the differential pressure between Zone (1) and (2) has fallen to 0.14 bar. Water
from Zone (2) flows into the open, both non-return valves close and thereby
separate Zone (2) from Zones (1) and (3). Thus, the risk of back pressure or
back suction into the supply network is avoided. The pipeline is disconnected
and the drinking water network is protected
