NOTICE
Insufficiently filled pump housing.
Danger of de-priming!
 It is imperative that the level sensor is set correctly so
that the pump casing is completely filled for immediate
pumping.
• Switch on the power.
• Check the phase connection:
The control box is equipped with a phase monitor to prevent two-
phase operation. Force start the pump (pumps, one after the other on
two-pump systems). In case of a «Phase» alarm, switch off the power at
the station, connect the 3 phases correctly at the control box.
• Check the direction of rotation of the pump:
Using a coin, unscrew the small cover on top of the pump. The upper
part of the motor shaft is now visible and marked with a trace of paint.
Turn the pump on by hand. Observe the direction of rotation of the
mark and compare it with the direction of the arrow (motor housing). If
they are not identical, switch off the power and invert 2 of the phases
at the control box. Screw the cover back on. Two-pumps installation: do
the same with the other pump.
WARNING
Presence of cutting impeller.
Risk of pinching, cutting or amputating fingers or other
body parts.
 Keep away from moving parts.
• On the control box, press the button «Auto» to carry a test Run:
– Open the inspection cover.
– Fill the collecting tank via the normal inlet (washbasin, toilet...) un-
til the pump switches on. The station must automatically switch on,
pump the tank empty and siwtch off again. After switching off, no
wtare may flow from the pressure line back into the tank.
– Double installations: both pumps must be switched on alternately.
– Correct the delay time according to the installation conditions and
the discharge height so that the pump empties the collection tank as
much as possible and only runs briefly in snore mode (louder noise
during pumping). The dip tube must no longer be immersed in the
liquid at the end of the pumping process (display 0 cm in the control).
The delay time can be changed on the control box.
– During the initial test run, check pipes for tightness and reseal them,
if necessary.
– Close the inspection cover.
If the station is working properly, leave it in automatic mode.
• Setting at the control box:
Activate the option «Automatic start every 24 hours» («24h start» then
«is activated» on the display of the control box). The pump(s) is (are)
then activated briefly even if no load is applied via the switch-on level.
This prevents blocking due to non-use.
5.3 OPERATING LIMITS
NOTICE
Pressure and temperature limits exceeded.
Leakage of hot or toxic fluid!
 Observe the operating specifications in the documen-
tation.
 Avoid running the pump with the valve closed.
 Dry running, without pumped fluid, must be avoided.
When in use, observe the following parameters and values:
Parameter
Max. allowed temperature of the
fluid
Operating mode
• The lifting unit is not designed for continuous operation! The convey-
ing data stated on the factory plate apply only for intermittent periodic
duty (S3 25 %).
• The maximum permissible feed flow must always be smaller than the
feed volume of a pump (see 3.6).
• Do not leave the lifting station unused for a long time (see 5.2).
NOTICE
Lifting station not in use for a long time.
Risk of seal blockage.
 Activate the option «24 hours start» on the control box.
 Do not disconnect the power supply to the lifting sta-
tion when not in use.
Value
35°C
up to 55°C when pumped 5 min
max.
Intermittent service S3 25%
6. DECOMMISSIONING
1. Close the valve on the inlet pipes.
2. Drain the tank by pressing the forced mode button on the control
box. Close the valve on the discharge pipes.
3. Switch off the electrical power supply and record the installation.
4. Inspect the hydraulic parts and shredding blades (depending on the
model). Clean them if necessary.
WARNING
Presence of cutting impeller.
Risk of pinching, cutting or amputating fingers or other
body parts.
 Even when switched off, care must be taken when han-
dling a pump.
 Keep away from moving parts.
 Never touch the impeller without protective equipment.
5. Clean the tank.
7. CLEANING/MAINTENANCE
DANGER
Disconnect electrical power before working

on the unit!
WARNING
Work performed on the pumping station by unquali-
fied staff.
Risk of injury !
 Repairs and maintenance must be performed by spe-
cially trained staff
WARNING
Work on the pumping station without adequate
preparation.
Risk of injury!
 Properly stop the pumping station and secure it against
inadvertent operation.
 Close the inlet valves.
 Drain the pumping station.
 Close the valve on the discharge pipes.
 Allow the pumping station to cool to room temperature.
7.1 INSPECTION AND MAINTENANCE SCHEDULE.
In accordance with EN 12056-4, pumping stations must be maintained
to ensure the proper disposal of wastewater and to detect and elimi-
nate malfunctions at an early stage.
The proper functioning of pumping stations must be checked by the
user once a month by observing at least two operating cycles. While
doing so, attention has to be paid for abnormalities, e.g unusual run-
ning noises of the pump. If irregularities are noted, call qualified staff.
According to DIN EN 12056-4, lifting units have to be regularly checked
within the following time intervals:
• every 12 months in case of installation in detached houses,
• every 6 months in apartment blocks,
• every 3 months in case of installation in commercial and industrial
enterprises.
In order to guarantee permanent operational safety of the lifting unit,
we recommend to conclude a maintenance agreement.
7.2 CHECKLIST FOR INSPECTION AND MAINTENANCE
Check the power supply. Compare the values with those of the rating
plate.
Check the connection of the power supply to the earth.
Check the connection of the power supply to a 30 mA GFCI breaker.
Check the proper operation of the motors by pressing the forced mode
buttons. If abnormal, make sure the pump is not clogged, check the
resistance values of the engine coils.
Check the motor rotation direction.
Perform a functional test over several cycles.
Check the correct installation and state of wear of the couplings.
Check the proper operation and effectiveness of the alarm device.
Check the proper operation and seal of the shut-off valves and non-re-
turn valves.
Dismount and clean the pitot tube.
Check the control line, check connections on the tank and on the con-
trol box.
Consult the alarm log (control box)
Consult the pump operation log (control box)
