5.9 Water vapour intake
In order to pump down any water vapour, the following operations are recommended:
Let the pump run for thirty minutes at the maximum vacuum in order to bring the pump
temperature to its operating value.
At the end of the working cycle, in case of further presence of condensate in the oil, let
the pump run for at least thirty minutes at the maximum vacuum.
It is advisable to carry out this operation before stopping the pump for a long time. The
gas ballast valve will allow the elimination of water condensate from the lubricating oil.
