NOTICE
Danger of interrupting the temperature reaction time by prematurely terminating
the sterilization.
Ineffective sterilization.
If necessary, repeat the sterilization.
The glass door and inner chamber become hot during sterilization.
CAUTION
Danger of burning by touching hot chamber parts during or after a sterilization.
Burns.
∅ Do NOT touch the glass door and inner surfaces for approx. 7 hours after prematurely
terminating the sterilization cycle.
21.3.4.2 Prematurely terminating the sterilization cycle after more than 4 hours, i.e.,
during the cooling-down phase: successful sterilization
The duration of the entire sterilization is 10 hours. If you want to shorten the sterilization procedure in order
to save time, you can prematurely terminate it during the cooling-down phase, i.e. no sooner than after 4
hours. At this point, the inner temperature is still approx. 140 °C / 284 °F.
The effective sterilization phase (heating up and holding phase) is automatically finished after 4 hours The
chamber is in the cooling-down phase, meaning that the necessary duration for the proper sterilization has
occurred.
The information “Successful sterilization” on the
controller display indicates a successful hot-air
sterilization.
The interior may still be hot. Do not touch the
glass door and inner surfaces!
Confirm the message with the Confirm icon.
After confirming the message the controller changes to Fixed value operation mode. The setpoints of Fixed
value operation mode are then equilibrated.

control is deactivated and will only be activated after confirming the information
message “Successful sterilization” and when the temperature has cooled down to a value
below < 80 °C.
If you prefer accelerating cooling-down, proceed as follows:
• If required, open the outer door.
• Cooling-down time:
• Front door open: at least 1 hour
• Front door closed: at least 4 hours
• If required, open the glass door.
