Once the appliance has been switched off, the water in the hose flows
back; this can be prevented by fitting a check valve. Installing a quick
shut-off valve to disconnect the hose in a suitable point simplifies

cleaning and maintenance. If the appliance is used in a drain sump
or pump pit, the holding reservoir must be large enough in volume to
ensure that the appliance is able to operate.
The appliance's float switch (A5) must be able to float freely, with no
restrictions, as otherwise normal operation cannot be assured. If it is
not certain that the float switch (A5) is able to trip on and off correctly,
the appliance must only be run under supervision.
6.4 Safety Measures
The user must prevent damage arising from the flooding of premises
or other causes in the event of a failure of the appliance or external
components by adopting suitable measures (e.g. installation of an
anti-flooding protection circuit, alarm system, backup pump, collection
tank or similar features), which must be connected to a separate,
fail-safe electrical circuit. The safety measures must be suited to the
specific conditions of use and must be able to reduce and/or prevent
the damage caused by water leaks.
The user must also install a spray guard to prevent water leaks or
splashes due to a pump failure from causing damage. A backup pump
or a floor drain must be installed to ensure that any water from leaks
is promptly removed. Otherwise, an alarm system can be installed
to trigger an alarm and/or an emergency shut-down of the appliance
and water supply in the event of a water leak, before damage to the
equipment or property can occur.
We also recommend raising all equipment in appliance installation
rooms about 5-10 cm above the floor so that any water leaks will
not cause immediate damage. The manufacturer accepts no liability
for damage caused by failure to comply with this recommendation.
Warning - danger! Dry operation
If the appliance runs for more than 5 minutes with the water suction point
closed, it may be damaged due to overheating. Switch off the appliance when
the normal water flow is obstructed.
Dry operation will damage the appliance beyond repair, so never allow it to
run dry for more than 10 seconds.
7 ADJUSTMENTS
7.1 Preliminary adjustments
The appliance is ready for operation; the only setting required is
adjustment of the float switch (A5) on and off tripping points to suit
the specific application.
7.2 Float switch adjustment
To adjust the float switch tripping point, shorten the cable of the float
switch in its clip (A5 b, fig. 7). The shorter the cable, the longer before
the switch trips on and the sooner it will trip off.
7.3 Special functions
7.3.1 Base variable for clean water or wastewater
In multi-purpose models, the feet on the base of the appliance can be
folded (A6) to switch the pump from wastewater to clean water mode.
In this case, the appliance sucks in water down to a residual depth of 5
mm, but it is only able to deal with suspended solids with particle size
up to max. 5 mm (fig. 8).

7.3.2 Locking the float switch (A5)
In some models, the float switch (A5) can be locked in the vertical
position in a support (A5 b, fig. 9). When the float switch is locked, the
appliance operates continually, regardless of the water level, and it
must only be operated under supervision to prevent dry running.
8 START-UP AND PRIMING
Warning - danger!
All installation and assembly operations must be performed with the appliance
disconnected from the mains power supply (fig. 3).
8.1 Start-up
After connecting the appliance as described in point 6 and after
implementing all safety instructions, the plug (A12) can be connected.
The appliance then starts automatically when the water level reaches
the height set for tripping of the float switch, and switches off again
when the switch-off level is reached.
8.2 Priming the pump
For priming / start-up, the appliance needs a water level about
30 - 50 mm above the minimum suction level. Once the appliance has
been primed, it is then able to pump down to the minimum level set.
The appliance sucks in water through the suction strainer (A1) in its
base and conveys it along a delivery hose connected to the delivery
sleeve (A3).
If water is not sucked in even though the water level is sufficient and
the motor is running, there may still be air in the pump body (A4).
Proceed as described in point 6.2 and bleed the appliance again.
8.3 Priming the pump
The appliance's stated flow rate values are maximum values, which
are reduced if external components (e.g. delivery hose, elbows,
restrictors, etc.) are used. This should be borne in mind when choosing
the appliance. The actual flow rate for specific installation conditions is
stated in the flow rate graph (fig. 10).
9 MAINTENANCE
Warning - danger!
Before any maintenance procedure and/or during troubleshooting, disconnect
the power cable (A8) from the socket. All maintenance and cleaning work can
then be carried out.
9.1 Cleaning
After each use, sluice the appliance and all external components with
clean water. Remove hard deposits with a jet of water. Dirt and clay
inside the pump body (A4) cause jamming of the impeller, leading to
malfunctions when the pump is restarted.
In the event that this procedure is overlooked, the appliance can be
immersed in water at up to 35°C for several days to dissolve the dirt.
9.2 Operating check
Check tripping of the float switch (A5) regularly to prevent malfunctions.
10 STORAGE
It is essential to protect the appliance from frost, and in case of
temperatures of +5°C or below it must be uninstalled and stored in a
dry place, protected from frost.
