Translation of the original operating manual
stated under "Aeration after stoppering" (see the illustration above, item
3). Then, the shelves are moved apart into the drying position. In the
second step, the system is aerated up to atmospheric pressure. This
method prevents the stoppers from being ejected from the vials (if the
shelves are moved apart without any prior aeration) and also from
sticking to the shelves (if the shelves are not moved apart until the
aeration to atmospheric pressure is complete).
3. Storage under defined conditions
The shelves are brought to the set "Storage" temperature (see the
illustration above, item 5) in order to store the product under optimum
conditions. These conditions are kept constant until the system is
manually set to the standby mode for unloading.
NOTE
If the variant "Aeration, storage" has been selected, the product is stored
at the "Aeration" pressure. In this case, the system must be aerated
manually up to atmospheric pressure prior to opening the loading door.

Special equipment: Preselection of the aeration medium
If the freeze-dryer is equipped with an automatic aeration valve and
automatic valves for media selection, this dialog box can be used to
preselect the medium that is to be used for the aeration medium requests
