Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L) 45/140
CAUTION!
Pay special attention to the three-phase motor, where an inversion of polarity
causes inversion of the direction of rotation of the pump with consequent
possibilities of mechanical damage.
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 (version with single-phase motor) or of the multipolar switch
(version with three-phase motor).
WARNING!
The pump is designed for operation with neutral or non-corrosive fluids. It is
absolutely forbidden to use potentially explosive or flammable substances.
There are no special procedures for switching the pump off; it needs
only to be disconnected from the electric power by means of the
bipolar switch (version with single-phase motor) or of the multipolar
