11.3 Brief operating instructions
1.
Switch the system on via the mains power switch on the right side of the
unit.
2.
Switch the vacuum pump and/or the cooling trap on.
3.
Close the lid.
4.
Starting the warm-up phase:
• Enter the set values for the warm-up phase under "menu"
"options"
"timer warm-up" and "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 with the aid of the up/down keys and confirm
with the right-hand function key "edit".
• Change the set value with the aid of the up/down keys and confirm
with the right-hand function key "ok".
• Quit the menu with the left-hand function key.
6.
Starting the process "evaporation manual":
• Open the "mode" menu with the left-hand function key.
• Select "evaporation manual" using the up/down keys.
• Start the evaporation process by pressing the right-hand function
key "enter".
The start of the evaporation process starts the following automatic
process run:
• The rotor speed increases (direction of rotation: anti-clockwise)
• At 70% of the selected maximum speed: the aeration valve closes
automatically (to avoid boiling retardation).
• 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 with the right-hand function
key.
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 boiling retardation).
• The rotor decelerates until it is at a standstill. After the standstill of
the rotor the lid can be opened in order to remove the rotors.
