The scale from 1 to 10 corresponds to a speed range of 20
to 300 rpm under nominal load.
Fill the evaporation flask
Manual filling: You can fill the evaporation flask manually
prior to creating the vacuum. The evaporation flask should
not be filled more than half its volume.
Automatic filling: Prior to filling the evaporation flask, a
vacuum controller is used to regulate the glass apparatus
to the target pressure.
• Now fill the evaporation flask using the back feed line.
Set up the heating bath
Refer to the operating instructions

of the heating bath!
• Move the drive to the bottom position and check the
position of the heating bath in relation to the evaporation
flask. When using larger evaporation flasks or depending
on the angle of the rotary drive, you can move the heating
bath to the right.
• Fill the heating bath with the tempering medium until the
evaporation flask is surrounded by tempering medium to
2/3 of its volume.
Adjust the drive height
To adjust the drive height, grasp the height adjusting
handle and hold the trigger (1).
The lift is unlocked and you can move the drive up and
down. Release the trigger, the lift is locked in the adjusted
height.
