The unit has been shut down for several days, and there is still a certain level of vacuum in the primary evacuation system – why is that?

The group has been shut down for several days, and there is still a certain level of vacuum with primary evacuation – why is that? The pressure gauge is fine
I’m not sure whether you stopped the system at stage 1 or stage 2 when parking it, and whether steam or air was stopped first. I think there’s an issue with the sequence in which those valves on the extractor are closed, but it should be fine
That’s impossible, unless there’s a problem with the pressure gauge
