Oil burnt from overheating Flush the vacuum pump
Replace the exhaust filter
Fill in new oil
( page 8: Maintenance)
In case the oil life is too short: use oil with
better heat resistance (
page 17: Oil) or ret-
rofit cooling
Mains frequency or voltage outside tolerance
range Provide a more stable power supply
Partial clogging of filters or screens
Partial clogging in the suction, discharge or
pressure line
Remove the clogging
Long suction, discharge or pressure line with
too small diameter Use larger diameter
The vacuum pump fumes or expels oil drop-
lets through the gas discharge

Version with oil return valve (RB 0006 C/E):
In case the vacuum pump runs for more than
0.5 hours without interruption, oil can collect
in the upper chamber of the oil separator (f)
to an extent that it gets expelled together
with the discharged gas
Regularly shut down the vacuum pump for
short periods of time. Check that the oil return
valve functions properly and lets oil run from
the upper into the bottom chamber of the oil
separator (f) as soon as the vacuum pump is
shut down (

The oil is watery and coloured white The vacuum pump aspirated water or signifi-
cant amounts of humidity
Version with gas ballast:
The filter of the gas ballast is clogged
