Assembly of a vacuum system
+ Assemble the vacuum connection line between the vacuum pump and
the vacuum application.
+ Assemble the vacuum connection line between the controller and the
vacuum application, if the controller is not part of a pumping unit.
+ Assemble electrical connections.
+ Connect coolant if necessary.
Vacuum for ltration and suction
+ Select ”Pump down” function.
+ If necessary, set value for ”Speed” (high or low pumping speed). Re-
duce the speed in case of fast sedimentation (formation of a lter cake).
+ Set ”Minimum” to a value which provides adequate suction but does
not lead to evaporation of the solvent.
+ Start process by pressing ”START/STOP” key.
alternatively:
+ Select ”Vac control” function.
+ Set ”Set vacuum” to a value which does not lead to evaporation of the
solvent.
+ If necessary, set value for ”Speed” (high or low pumping speed). Re-
duce the speed in case of fast sedimentation (formation of a lter cake).
+ Set ”Maximum” pressure setting so that pump will switch off at the end
of the ltration process, or in the event that a lter cake cracks, leading
to a sudden pressure increase.
+ Start process by pressing ”START/STOP” key.
+ Tip for ltration: Adjust preset pressure to a value well above the
boiling pressure of the solvent (e.g., for water >>15 Torr (20 mbar)).
Set the maximum pressure to e.g., 375 Torr (500 mbar). Once the l-
tration has nished, the pressure increases and the pump is switched
off automatically.
