Translation of the original operating manual
At the end of the process, a pop-up window with a safety enquiry
(confirmation prompt) opens. Following the confirmation of this enquiry, the
freeze-dryer will be switched to standby.
Evaluation:
The test is passed if the dishes do not contain any water/ice after the end of
the process.
Capacity test -50°C (4)
NOTE
The capacity test -50°C is intended for units with a minimum of two
double-stage refrigeration systems.
The capacity test -50°C is a freeze-drying program/ for verifying the ice
condenser capacity (when the shelves are cooled to -50°C in the "Freezing"
phase). For this purpose, the shelves must be loaded.
Procedure:
• Load the shelves evenly with water in dishes for the test. The water
quantity must be 2/3 of the maximum ice condenser capacity that is
specified for the freeze-dryer.
• In the main window "Manual", select the button "Operating mode:
select/start"
– "Standard unit test".
• Select "Capacity test -50°C" and start the program via the "Run" button.
In the "Freezing" phase, the shelves are cooled to -50°C. The parameters
for the subsequent "Main drying" and "Secondary drying" sections have
been configured in such a way that the water will be completely sublimated
out of the dishes and bound on the ice condenser after 24 hours.
At the end of the process, a pop-up window with a safety enquiry
(confirmation prompt) opens. Following the confirmation of this enquiry, the
freeze-dryer will be switched to standby.
Evaluation:
The test is passed if the dishes do not contain any water/ice after the end of
the process.
