When the Turbo-V pump and the backing pump are stopped and
the system is at atmospheric pressure, for a better bearing
protection it is advisable to leave the purge gas flowing into the
Turbo-V pump, with the chamber or the Turbo-V vent valve
opened, to avoid system overpressures. If the vent valve can't be
kept opened, the backing pump should be left operating.
