2.6 Operating advices (See chapters 1.1.1, 1.1.2, 1.1.3 and
1.2)
When removing condensable vapours, a gas ballast valve must be installed or
opened.
The vacuum pump must be run for 30 minutes prior to operation with the
inlet connection closed, in order to reach the operating temperature of about
75°C. Only up from this operating temperature, condensable vapours can be
transported. After use, the pump has to be left running for an additional 30
minutes with the inlet connection closed and open gas ballast, to clear the oil of
condensate.
2.7 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 2.6 (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 1.7.
