o
The circulation pump can be installed in the outflow or return flow pipe of
heating/air conditioning systems – arrows on the pump housing indicate
the flow direction.
o
Preferably, the pump should be installed above the minimum water level of
the heating boiler, and as far away as possible from bends, angles, and
branch pipes.
o
To simplify inspection and maintenance work, shut-off valves should be
fitted in the outflow and return flow pipes.
Markings
on
the
packaging
must
be
strictly
observed.
The
pump
should
only
be
unpacked
immediately
before
installation.
