23.3.2 Performance during sterilization
Normal display during sterilization (example during heating up phase)
Sterilization
The information message “Sterilization” is shown alternating with the indication “Temp. / CO2”.
The CO
2
actual value display shows “ – – – – ” because the CO
2
sensor is disconnected.
The zero-voltage relay alarm output and the buzzer are not activated.
When starting a hot-air sterilization, CO
2
control deactivates automatically.
The safety controller settings are inactive during sterilization. They become functional again
following termination of the sterilization and/or restarting the chamber at the main power
switch.
Glass door and inner chamber become hot during sterilization.
CAUTION
Danger of burning by touching hot chamber parts during a sterilization.
Burns.
∅ Do NOT touch the glass door, glass door, inner surfaces, and door gaskets during a
sterilization.
Opening the outer door leads to prematurely terminating the running sterilization cycle (chap. 23.5). If this
happens during the heating up or holding phase (during 6 hours after starting the sterilization cycle), steri-
lization will be ineffective (chap. 23.4.1).
NOTICE
Danger of interrupting the temperature reaction time by opening the outer door
during the heating up or holding phase.
Ineffective sterilization.
∅ Do NOT open the chamber doors during the heating up or holding phase of the sterili-
zation cycle
23.3.3 Completing the entire sterilization cycle
After 6 hours the information message “Sterilization success” indicates the successful sterilization. The
cooling down phase starts.
The entire sterilization cycle ends after a total of approx. 12 hours.
• When the inner chamber has cooled down to a value below 60 °C / 140 °F, turn off the chamber and
plug in the CO
2
sensor.
The CO
2
sensor is temperature resistant up to a maximum temperature of 60 °C / 140 °F
• Start up the chamber (chap. 6)
The chamber is now ready to operate.
