t
until the vacuum pump does not reduce the pressure further, i.e. until the minimum possible
vacuum pressure is reached.
Enter this value and confirm the values.

Start process: Lift ...
Only variants with motor-driven lift: In this menu, define the behavior of the flask lift at the start of
the process.
Touch the function button to switch between the two options:
t
[Start process: Lift on]: With this selection, the flask lift automatically moves to the lower
y
end position when starting the process and the evaporation flask is thus automatically
immersed in the heating bath.
[Start process: Lift off]: With this selection, the flask lift remains in the upper end position
y
on starting the process; the evaporation flask must be immersed in the heating bath
manually.
Confirm your entry with [OK] to accept the selection.
t
Deactivate this function when using a foam brake and on devices using a
large evaporation flask to prevent damage to the flask!
