5. Installation and start-up
Switch off 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 flow switch
(Fig. 1 / Item 1) with the connection 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 flow 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 flow switch
cannot work correctly. Raise the non-return valve at
the handle (Fig. 2 / Item 7) (Fig. 5) and carefully fill
the flow switch with the transport fluid up to the
bottom 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 provided
for it (Fig. 2 / Item 6) on the flow switch and ensure
that you seal the connection properly, for example
with Teflon tape (not supplied). Connect the pump's
mains plug to the socket (Fig. 1 / Item 2) on the rear
of the flow 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 flow switch to an
adequately fused (at least 10 A) 230V ~ 50Hz safety
mains socket with a ground contact. The flow switch
is now ready for use. Switch on the pump if it is fitted
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 fluid is emitted from it. The flow switch will
now switch off the socket (Fig. 1 / Item 2). To
dismantle, proceed in reverse order. If you place it
into storage, ensure that the flow switch does not
contain any transport fluid so as to avoid frost
damage.

6. Operation
The flow 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 flow switch is connected to the power supply
Yellow LED: The flow switch has tripped, the socket
(Fig. 1 / Item 2) is live.
Red LED: The flow switch has detected a fault
The following operating statuses are indicated:
Green is lit: The flow switch is ready for use, no
transport fluid is required. The pump is not
running.
Green and yellow are lit: The pump is
operating, a consumer for discharging transport
fluid is open.
Green and red are lit: The pump is running dry
without transport fluid. The flow switch will
attempt to rectify the dry running three times
before the dry running guard finally trips.
Green is lit, red is flashing: The dry running
guard has tripped, it is no longer possible to draw
in the transport fluid. Find the cause of the fault
using the pump's operating manual (for example
leaking intake line) and rectify it. Then restart the
pump by pressing the Reset button (Fig. 2 / Item
9) on the flow switch.
7. Replacing the power cable
If the power cable for this equipment is damaged, it
must be replaced by the manufacturer or its after-
sales service or similarly trained personnel to avoid
danger.
8. Maintenance
The flow switch requires no maintenance. The only
requirement is for regular checks on the screw
connections and line to ensure that they are correctly
positioned, secure and not leaking so that error
sources can be identified and rectified as soon as
possible.
