Max. temperature: ........................................ 55°C
5. Installation and start-up
Switch o
ff
the pump and pull the pump’s mains
plug. Remove the existing output line on the actu-
al pump. Ensure that you bleed the pump correct-
ly (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 bot-
tom end of the thread on the pressure connector
(Fig. 2 / Item 6) to prevent the system running dry.
Now screw the output line to the connector pro-
vided for it (Fig. 2 / Item 6) on the
fl
ow switch and
ensure that you seal the connection 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) 230 V ~ 50Hz safety mains
socket with a ground contact. 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 medi-
um. 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.
6. Operation
The
fl
ow switch cannot be adjusted or switched, it
is fully automatic. There are only 3 LEDs (Fig. 2 /
Item 8) to indicate its operating status.
Green LED:
The
fl
ow switch is connected to the power supply
Yellow LED:
The
fl
ow switch has tripped, the socket (Fig. 1 /
Item 2) is live.
Red LED:
The
fl
ow switch has detected a fault
The following operating statuses are indica-
ted:
Green is lit:
The
fl
ow switch is ready for use, no transport
fl
uid
is required. The pump is not running.
Green and yellow are lit:
The pump is operating, a consumer for dischar-
ging transport
fl
uid is open.
Green and red are lit:
The pump is running dry without transport
fl
uid.
The
fl
ow switch will attempt to rectify the dry
running three times before the dry running guard
fi
nally trips.
Green is lit, red is
fl
ashing:
The dry running guard has tripped, it is no longer
possible to draw in the transport
fl
uid. Find the
cause of the fault using the pump’s operating ma-
nual (for example leaking intake line) and rectify
it. Then restart the pump by pressing the Reset
button (Fig. 2 / Item 9) on the
fl
ow switch.
