+
Select function ”
VACUULAN”.
+
Set ”Set vacuum” to a pressure which can be reached reliably in the
vacuum network. Take account of the ultimate vacuum of the pump
and of the system’s leak rate in case of no vacuum demand.
+
Set ”Switch on” pressure appropriately to ensure sufficient vacuum for
all connected applications.
+
Set ”Delay” if necessary.
+
Start process by pressing ”START/STOP” key.
Vacuum for VACUU•LAN networks
Vacuum for filtration and suction
+
Select ”
Pump down” function.
+
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” (and ”Hysteresis”, if necessary) to a value which
does not lead to evaporation of the solvent.
+
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.
alternatively:
+
Select
”Vac control” function to dry at a predetermined vacuum level.
+
Set ”Set vacuum” to the preferred evaporation vacuum of the solvent.
Adapt ”Hysteresis” if necessary.
+
Set a process time (”Duration”) if necessary.
+
Start process by pressing ”START/STOP” key.
