Step 2
The user is prompted to remove all reagent bottles from the
instrument (
Fig. 220 ). When the prompt has been confirmed
by the operator, a vacuum is generated at each reagent position
and then any remaining reagent in the hose is drawn into the
retort. During this process, a check is carried out of whether (a
greater than negligible quantity) of reagent has penetrated into
the retort and whether the vacuum is released quickly enough.
This serves to detect whether the bottle has really been re-
moved.
Finally, pressure is built up in the retort several times; then it is
vented normally (pressure cycles).

Step 3
Before the third step, the operator is prompted to place an empty system bottle or RTU-bottle in the position in the drawer that was
defined with cleaning xylene (in the example,
Fig. 221 , item D5).
This must be confirmed by touching the OK button in the message window.
