There are some steps in which the retort
CANNOT be opened and others in which
the retort MUST NOT be opened.
While a program is running, NEVER open the retort lid in a step
other than “Processing”. Alarms may occur that would make the
computer control system abort the process. Potentially toxic or
flammable substances may exit from the retort.
The retort
can be opened when the second message line displays “Processing”.
Please take the following precautions:
•
Close the lid as soon as possible.
•
Immediately close the lid if the “Processing” message changes.
Respect all the safety rules about the precautions to take when
handling toxic or flammable substances.
•
If the system is processing during a vacuum step, it will be necessary to
press the key VACUUM RELEASE before opening the retort. The second
message line will then display “Normalizing pressure in the retort,” and,
after 10 seconds, the retort can be opened. Within one minute the
processor will again try to create a vacuum if the step requires this
operation. If the Retort is not closed within this time, a non-blocking alarm
will occur (VACUUM TIME-OUT) and for the remaining time of the step the
processor will
NOT try again to create a vacuum. Processing quality could
be compromised.
•
If the opening of the retort is difficult, DO NOT force it. Instead, press the
VACUUM RELEASE key and try again. This may also be necessary when
the closed retort is passing from a “hot” to a “cold” state (e.g., immediately
after a process) as this creates an internal vacuum that makes it difficult or
impossible to open.

At the end of a program, the instrument leaves the last reagent in the Retort to
prevent the samples from drying out. Press
ENTER to empty the retort.
