HS452, HS652 Rotary Vane Pumps User Manual / 87-900-978-01 (H) 45/102
Use
Before being put into service, in order to reach maximum vacuum,
the pump must be left running for about an hour with the gas ballast
valve open. This will eliminate any humidity from the oil.
There are no special procedures for switching the pump on; it needs
only to be connected to the electric power by means of the bipolar
switch.
WARNING!
The pump is designed for operation with neutral or non-corrosive fluids. It is
absolutely forbidden to use potentially explosive or flammable substances.
