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

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.
Three-phase version: check the motor rotation direction.
Perform a functional test over several cycles.
Check the correct installation and state of wear of the flexible cou-
plings.
Check the proper operation and effectiveness of the alarm device.
Check the proper operation and seal of the shut-off valves and non-re-
