5.1 Installation and start-up
Switch o
ff
the pump and pull the pump’s mains plug. Remove the
existing output line on the actual pump. Ensure that you bleed the
pump correctly (refer to the pump’s manual for further details). Screw
the connection adapter (Fig. 1 / Item 4) to the output line connector
on the pump (Fig 3). Fit the
fl
ow switch (Fig. 1 / Item 1) with the con-
nection thread (Fig. 2 / Item 5) to the connection adapter and secure
it to the connection adapter using the union nut (Fig. 4 / Item 10) (Fig.
4). The
fl
ow switch must be in an upright position, in other words the
connector for the pump (Fig. 2 / Item 5) must be at the bottom and the
connector for the output line (Fig. 2 / Item 6) must be at the top. If it is
in any other position, the
fl
ow switch cannot work correctly. Raise the
non-return valve at the handle (Fig. 2 / Item 7) (Fig. 5) and carefully
fi
ll
the
fl
ow switch with the transport
fl
uid up to the bottom end of the th-
read on the pressure connector (Fig. 2 / Item 6) to prevent the system
running dry. Now screw the output line to the connector provided for
it (Fig. 2 / Item 6) on the
fl
ow switch and ensure that you seal the con-
nection properly, for example with Te
fl
on tape (not supplied). Connect
the pump’s mains plug to the socket (Fig. 1 / Item 2) on the rear of the
fl
ow switch. After checking all the connections and lines, connect a
consumer to the output line and open it so that any air in the output
line can escape when the transport process is started. Connect the
mains lead (Fig. 1 / Item 3) on the
fl
ow switch to an adequately fused
(at least 10 A) 230V ~ 50Hz safety mains socket with a ground con-
tact. The
fl
ow switch is now ready for use. Switch on the pump if it is
fi
tted with a switch, otherwise the pump will now start automatically
and will start to transport the medium. The consumer can be closed
as soon as the transport
fl
uid is emitted from it. The
fl
ow switch will
now switch o
ff
the socket (Fig. 1 / Item 2). To dismantle, proceed in
reverse order. If you place it into storage, ensure that the
fl
ow switch
does not contain any transport
fl
uid so as to avoid frost damage.
