Start-up
30
➜ Enter the atmospheric pressure determined with the external pressure gauge.
➜ Close all openings on the evaporator system.
✓ When the atmospheric pressure has been entered and confirmed, the vacuum control
will start automatically. When the system has been evacuated to a low value and
keeps it stable, the second calibration value can be entered.
➜ Wait until the attached vacuum pump cannot reduce the pressure any further and
consequently the lowest possible vacuum pressure has been reached. Enter this
value.
➜ Confirm this value.
The calibration has now been corrected on the basis of the entered values.
If calibration is cancelled, the entered values are discarded. If you restore the factory
settings, the entered calibration values are also discarded and replaced by the default
values.
10. Lift activation
For motor lift devices, you can set that the flask is automatically lowered into the heating
bath upon starting the processes. The lift will move completely downwards. If you use
a foaming inhibitor or a different individual arrangement with a bigger glass flask, you
can also suppress the automatic downward movement of the lift at the start to prevent
potential glass breakage.
➜ Tap “Start all: Lift deactivated” /“Start all:
Lift activated”.
✓ If you have selected “Start all: Lift deacti-
vated”, you have to immerse the flask by
means of the lift buttons.
11. Factory settings
You can restore the factory settings at any time.
When you tap “Factory settings” and confirm the security prompt, your
favorites and ramp profiles are deleted!
➜ Tap “Factory settings”.
✓ The factory settings or the settings of the
last update are restored.
