The recommended minimum flow pressure at
the installation position is ≥ 0.19 MPa. Solely
specialist contractors and expert personnel are
permitted to install and maintain this valve. The
generally accepted codes of practice and the

may lead to damages to the
system or malfunctions.
Important notes for the erection
• Remove the valve from the packaging just
before installation.
• Thoroughly flush the pipework before
installation.
• Mount the valve so that the drain faces
down vertically.
• Comply with the direction of flow!
• For inspection and maintenance purposes,
the installation site should be easily acces-
sible.
• Observe the minimum clearances given in
the technical specifications (chart „Interfe-
rence dimensions, page 20).
• Install the valve only in rooms that are
protected from frost and flooding.
•
According to DIN EN 1717, in order to
maintain flawless functioning of the BA
backflow preventer, a flanged dirt trap must
be installed in the direction of flow before
the BA backflow preventer.
• Do not connect any fast-closing valves or
stopping equipment before or after the
valve. Fast closing, e.g. of solenoid valves
or ball valves on devices and machines can
lead to serious malfunctions in the PROTECT
RPZ Outlet Valve Type BA. For that reason,
always use slowly closing valves or drives
that close slowly.
• If the inlet-side static system pressure is
high, it is recommended to install a pressure
reducing valve in the supply line.
• No additional, unprotected drinking water
connections are permitted after the backflow
preventer.
