Operating fluid return
line
Due to the automatic operating fluid return, it is not necessary to drain the operating fluid
manually.
However, depending on the process, filtered condensate in the oil sump should occa-
sionally be drained in the OME, since it could enter the operating fluid return to the pump.
NOTICE
Make sure that the return for the operating fluid is working properly.
The operating fluid can only be sucked out and returned when there is a minimum about
of operating fluid in the oil mist eliminator.
If necessary, top up with operating fluid in order to ensure the return of operating fluid
at the start of the evacuation phase.
Pour the operating fluid slowly into the outlet flange of the oil mist eliminator until it
can be seen in the sight-glass.
