NOTICE
Damage to the pump due to condensate in the operating fluid!
Returned condensate generated by vapors or by temperature differences between the
oil mist filter and pump impairs the quality of the operating fluid and negatively impacts
the pump's final vacuum.
Drain operating fluid built up with condensate in a time manner.
NOTICE
Risk of the filter elements becoming blocked with resin!
When pumping gases and vapors with a tendency towards polymerization, the ONF fil-
ter elements can become resinified.
Observe the corresponding safety devices such as the saturation indicator or pres-
sure relief valve.
NOTICE
Make sure that the return for the operating fluid works.
Operating fluid is only sucked in and returned from an operating pressure of < 100 hPa
and starting from a minimum quantity of operating fluid in the ONF.
Long evacuation phases with a high intake pressure should always be followed by
operating phases with a lower operating pressure.
