mode when positions are deactivated. This allows a fast and efficient flushing when using a reduced

Flush into waste:
• Open MENU  FLUSH. Set the time to flush with
solvent. FLUSH INTO makes it possible to choose
between waste or vial. Choose WASTE using the

according to the recommended parameter in the
table above. The CURRENT row in the SOLVENT
section shows the settings of the currently active
method. Press COPY to use these entries or set
new values using the selection knob. Press START
on the function button.
NOTE
The green START and red STOP button do not have
any influence on the flush process. To stop the process
open the flush submenu again and press STOP.

• Open MENU  FLUSH and choose VIAL for the
FLUSH INTO entry using the selection knob. Set all
other parameters as described above and shown in
the reference settings table.

When changing the solvent reservoirs (e.g. from hexane to ethanol), take out the filter and rinse it
thoroughly with the new solvent to prevent contamination with the old solvent.
6.2.7 Activating the EcoMode
In the normal operating mode the instrument is ready for operation and therefore keeps the tempera-
ture constant at the level set in the PREHEAT menu. It is however possible to activate the EcoMode
which automatically turns off the heater once the current extraction is finished. It is recommended that
this mode be used for unattended last extraction runs such as overnight runs. By turning the instru-
ment off and on, the EcoMode is automatically deactivated.
Activating the EcoMode:
• Open EXTRACTION  PREHEAT. Move down to
ECOMODE with the corresponding function button
and activate it using the selection knob. There is no
need to confirm with ON. By simply ticking it the
ECOMODE is already activated.
NOTE
The EcoMode can also be activated while the last extraction is already running without interruption.
It is therefore not necessary to pause the process. Simply open the PREHEAT submenu and tick
ECOMODE.
