Translation of the original operating manual
If the vacuum control system of the freeze-dryer uses a regulated gas
admission (injection), the preselected medium will be used for this purpose.
If the freeze-dryer is equipped with the "Aeration, Stoppering, Storage"
option, the preselected medium will be used for the aeration up to
stoppering (backfilling) as well as for the final aeration up to atmospheric
pressure.
The following media preselection settings are possible:
• Air: Preselects the media connection "Air".
• Inert gas: Preselects the media connection "Inert Gas".
• Automatic: Automatic media connection preselection depending on the
chamber pressure and stoppering status of the product vials:
- Chamber pressure 950 mbar or product vials already sealed by
way of "Aeration, Stoppering, Storage": Preselection of the media
connection "Air".
- Chamber pressure < 950 mbar and product vials not yet sealed by
way of "Aeration, Stoppering, Storage": Preselection of the media
connection "Inert gas".
As a result, during automatic aeration, stoppering, and storage, backfilling
can be performed automatically with inert gas and the subsequent aeration
of the chamber up to atmospheric pressure with air.
Special equipment: Gas injection with a proportional valve (4)
see chapter 6.5.1.3 - "Main window "Options"", section "Special equipment:
Gas injection with a proportional valve"
Program templates (2)
The PGMplus programmer module offers various program templates that
include recipes for all kinds of freeze-drying applications. They are
suggestions for orientation purposes and must be adapted to the specific
area of application of the freeze-dryer.
NOTE
Some of the tests that are described under chapter 6.5.1.1 - "Main window
"Manual"", section "Operating mode: select/start", are also available in the
form of program templates.
Following the selection of a program template, a window containing
information concerning the drying process will be displayed.
