Assembly of a vacuum system
+
Assemble vacuum connection lines between vacuum pump, CVC
3000 and 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 filtration 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 filter cake).
+
Set ”
Set vacuum
” 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 filter cake).
+
Set
”Maximum”
pressure setting so that pump will switch off at the end
of the filtration process, or in the event that a filter cake cracks, leading
to a sudden pressure increase.
+
Start process by pressing ”START/STOP” key.
+
Tip for filtration:
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 fil
-
tration has finished, the pressure increases and the pump is switched
off automatically.
