alternatively:
For diaphragm pump with in-line valve and/or Vacuum-Management-
System
+
Select ” Vac control” function.
+
Set ”Set vacuum” (and ”Hysteresis”, if necessary) depending on the
solvent and the bath temperature.
+
Considering the hysteresis and the bath temperature, set ”Set vacu-
um” to a value which ensures that the solvent will definitely boil.
+
To set ”Maximum” is usually not necessary, unlike filtrations, because
the pressure does not increase at the end of the evaporation.
+
Set a value for ”Duration” if the process should be terminated auto-
matically after a definite time.
+
Use ”Delay” to pump out condensate and clean the pump at the end of
the process. The in-line valve is closed and so the pump is separated
from the application. During ”Delay” the coolant valve is still open.
+
Start process by pressing ”START/STOP” key.
alternatively:
For NT VARIO / VARIO-B diaphragm pumps (vacuum control with
pinpoint precision)
+
Select ” Vac control” function.
+
Set a maximum ”Speed”, to select a faster or slower process.
+
To set ”Maximum” is usually not necessary, unlike filtrations, because
the pressure does not increase at the end of the evaporation.
+
Set a value for ”Duration” if the process should be terminated auto-
matically after a definite time.
+
Set ”Set vacuum” depending on the solvent and the temperature.
+
Start process by pressing ”START” key.
+
To temporarily switch to ”Auto mode”: Press ”MODE” key. The
controller switches to ”Auto mode”. The setting of the controller does
not change due to this switching. After pressing ”START/STOP” key
the controller is in ”Vac control” again.
