7 Operating instructions
7.4 Operation
1. Check the cleaning unit for
correct operation (correct flow
from outlet, counter pressure
and vibration). This is especially
important the first time the cleaning
unit is run after installation or
dismantling and assembly.
2. When the collecting tank is
nearly full, the pump is stopped
automatically and the lamp on the
control unit lights up. The display
shows alarm. Empty the tank and
restart the pump to continue the
cleaning.

Recommended counter pressure
is 100 – 180 kPa
7.5 Standby
If an alarm occurs in Production mode, the system goes into Standby
mode. The feed pump is stopped and the pressure regulating valve
is opened. The operator can also choose to go to Standby by
tapping the Standby button. When there are no alarms active and
unacknowledged, the operator can tap the Start button to resume
separation by returning to Production mode.
NOTE
If an alarm has forced the system into standby, never do more than one pump
restart. Check and remedy the cause. Several restarts can damage the pump,
which can also result in damage to the pump housing and/or motor.
7.6 Stop
1. The cleaning unit is stopped by tapping the
Stop button, or if an alarm forces the system to
stop. Feed pump and separator are turned off.
Pressure regulating valve is opened.
NOTE
After each stop of the cleaning unit, the separator bowl
must be cleaned well. If not, an unevenly spaced sludge
cake will at next start result in heavy vibration and can
cause damage.
