7.5 Operation
1. Check the cleaning unit for correct operation
(temperature, counter pressure and vibration).
This is especially important the first time the
cleaning unit is run after installation or dismantling
and assembly.

Recommended counter pressure is 60 – 90 kPa
2. For purifier mode only!
Check that no oil is leaking out via the water outlet
(1). Preferably use a torchlight for checking.
If leakage is occurring, see
8.12 Some liquid
escaping through drain outlet to collecting tank
on page 53
.
3. When the collecting tank is nearly full, the
pump is stopped automatically and the lamp on
the control unit lights up. Empty the tank and
restart the pump to continue the cleaning. It
is possible to recover any oil by proceeding as
described in

7.6 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.
