Water vapour intake
In order to pump down any water vapour, the following operations
are recommended:
Before aspiring vapors, 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 with Gas-ballast open.
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.
See “Techincal Information” for the insertion procedure or exclusion
of the gas ballast.
Maintenance
Personnel responsible for pump operation and maintenance must be
well-trained and must be aware of the accident prevention rules.
In addition to the requirements listed below, please refer to the
paragraph “Safety rules”.
WARNING!
Introduce air in the inlet circuit before every maintenance operation.
