„SAFE" appears in the Display Speed
Whether or not the safety cut-off is active (ON) or switched off (OFF) is shown in Display II (Temp

Switching off the safety cut-off is the sole responsibility of the user.
This function does not work during distillation without vacuum! Here, the safety
cut-off offers protection in case of excess pressure.
Even when using the auto function, the function only activates after the limit value
is exceeded. Ensure by experimentation that the set limit values are never reached!
The current limit value is shown in Display I (vacuum)
e.g. 900 mbar. The limit value can be changed with the arrow
keys.
The process must be concluded by switching off the master
switch „Power".
