4 Operation
4.1 Operating advices
See safety information page 3.
When removing condensable vapours, a gas ballast valve must be installed.
The vacuum pump must be run for 30 minutes before operating with condensable
vapours with the inlet connection closed, in order to reach the operating tempera-
ture of about 75 °C. Only up from this operating temperature, condensable va-
pours can be pumped. After use, the pump has to be left running for an additional
30 minutes with the inlet connection closed, to clear the oil of condensate.
Use ear protection in case of operation at high inlet pressures.
Clean eventual oil on the floor.
4.2 Shutdown
The inlet flange of the SOGEVAC
®
pumps contains an anti-suck back valve. It
closes the inlet flange when the pump is voluntarily or accidentally shut down,
thus maintaining the vacuum in the connected system and preventing oil from
being sucked back into the system.
Except the indications in chapter 4.1 (operating advices) there are no particular
precautions for the shutdown of the pump.
If the pump must be stopped for a longer period, see chapter 2.3.
