Operation

2.1

Connection to the Vacuum System

The Vacuum Switch is mounted vertically. This ensures
that condensate can escape. Flange and gaskets must
be free of dust and grease. If the Vacuum Switch is to be

floated (electrically) it has to be separated from the
vacuum system by an insulating piece (Equipment see
Section 1.4.2).
