Continuous pumping

Pumping down until the ultimate vacuum of the pump is
attained 

(e. g. pump down to dry the system from volatile liq-

uids):
If the controller is in mode two-point control:

Press key MODE to change to continuous pumping.

Mode change is only possible if the process control is inac-
