2. Switch on the cooling trap and/or the vacuum pump.
3. Close the lid.
4. Starting the warm-up phase:
• Enter the set values for the warm-up phase into "menu" – "options" –
"Timer warm-up" und "Temperature warm-up", confirm your entries
and quit the menu.
• Press the left-hand function key "mode".
• Select the "Warm-up" menu and confirm.
• Open the lid when the warm up phase has ended.
• Install the rotors and close the lid.
5. Changing the set values for time, temperature, vacuum and safety
pressure:
• Select "menu" with the right-hand function key.
• Select "Change set values for manual mode" from the main menu.
• Select the set value by using the up/down keys and confirm with the
right-hand function key "edit".

• Start the evaporation process by pressing the right-hand function
key.
• The function "Evaporation program" can only be selected if a
program has been created before.
• The start of the evaporation process starts the following automatic
process run:
- The rotor speed increases (rotating direction left),
- At 70% of the selected maximum speed: the aeration valve closes
automatically (to avoid delays in boiling),
- At 80% of the selected maximum speed: the stop valve opens the
connection to the vacuum pump,
- Further speed increase until the preselected maximum rotor speed
is reached.
7. Interrupting an evaporation process:
• Press the left-hand function key "mode".
• Select "Stop evaporation" and confirm.
Without an interruption, the evaporation process ends after the
preselected time. The following process runs automatically:
• At maximum speed: the stop valve closes the connection to the vacuum
pump, the aeration valve opens; the rotor speed is maintained for 30
sec (aeration phase, to avoid delays in boiling).
