9. If the system will not be used immediately in reg-
ular operation, then switch the switchgear over to
Standby mode.
NOTE
In the event of prolonged system downtime
before regular operation, please close all of the
shut-off devices and switch off the switchgear.

6.2. Operation

6.2.1. Application limits
The defined utilisation limits must not be exceed-
ed:
• Max. inlet:
• CORE 20.2: 20 m³/h
• CORE 45.2: 45 m³/h
• CORE 50.2: 50 m³/h
• CORE 60.2: 60 m³/h
The maximum inflow must always be less than
the volume flow of the pump at the respective
duty point
• Max. reservoir flooding:
• CORE 20.2: 5 m for max. 3 h
• CORE 45.2, 50.2, 60.2: 6,7 m for max. 3 h
• Max. permitted pressure in the system pressure
pipe: 6 bar
• Max. fluid temperature: 40 °C
• Max. ambient temperature: 40 °C
• Fluid is present.
Dry running can lead to damage to the motor,
and is strictly prohibited!
6.2.2. Conduct during operation
When operating the lifting unit, always follow the
locally applicable laws and regulations for work
safety, accident prevention and handling electri-
cal machinery.
The motor housing of the sewage pump can reach
temperatures of up to 100°C during operation.
A corresponding working area must be defined
by the end-user. No personnel are permitted in
this safety zone during operation and no readily
flammable and combustible objects may be
stored there.
The working area must be marked in a way that
is unambiguous and clearly recognisable!
BEWARE of burns!
The motor housing can reach temperatures
of up to 100°C during operation. There is a
risk of burns! If personnel are present in the
working area during operations, then a guard
must be installed.
To help ensure safe working practice, the respon-
sibilities of employees should be clearly specified
by the operator. All personnel are responsible for
ensuring that regulations are observed.

COMMISSIONING/OPERATION
6.2.3. Regular operation
The lifting unit operates in automatic mode by
default and is switched on and off using the inte-
grated level control device.
1. Switching on the system via the switchgear: Main
switch to "ON".
2. Check the switchgear's operating mode. The
switchgear should be in automatic mode.
3. Check whether all shut-off devices are opened
and open any shut-off devices which may be
closed:
• 1x Inlet pipe
• 2x Blocking of the solids separation reservoir
• 2x Discharge pipeline
• On-site shut-off devices in the pressure pipe if
necessary
4. The unit now runs in automatic mode.
6.2.4. Overflow of the lifting unit
The lifting unit is overflow-proof, and can contin-
ue to be operated even in flooded condition.
6.2.5. Emergency operation as single-pump system
DANGER due to toxic substances!
During emergency operation, there is poten-
tial for contact with fluids that represent a
health hazard. The following points must be
observed without fail:
• Wear appropriate full-body protection as well
as protective goggles and mouth protection.
• Immediately wipe up drips.
• Channel the flushing water into the sewer
system at a suitable point!
• The protective clothing and cleaning cloths
must be disposed of acc. to waste code
TA 524 02 and EC Directive 91/689/EEC, or acc.
to local directives!
In the event of a fault, the function of the lifting
unit can be maintained in emergency operation.
The lifting unit can continue to be operated as a
single-pump system to this end.
The following points must be observed if the
system is working in emergency operation:
• The inlet in the respective solids separation reser-
voir must be closed off and the respective pump
must be switched off via switchgear.
• The operating mode of the pump must be ob-
served for the operation of the active pump!
• Given that the system continues to be in opera-
tion, the collection reservoir will continue to be
filled. If the pump is dismantled, then the sewage
will be pressed out of the collection reservoir via
the connection port!
A shut-off lid for the connection port is available
as an accessory for operation without pump. This
must be mounted immediately after the pumping
procedure!
• The solid materials remain in the solids separation
reservoir. They must be disposed of accordingly
when the solids separation reservoir is opened.
