Binder CB 160 - Terminating the Completed Sterilization Cycle

CB (E6.1) 07/2017 Page 113/145
To abort the sterilization cycle proceed as described in chap. 18.3.3. The
symbol then disappears
from the controller display.
The inner chamber and parts inside can still be hot. Do not touch.
The defined cooling down phase lasts 6 hours until reaching 37 °C / 98.6°F and is followed by a holding
phase at 37 °C / 98.6°F of unlimited duration
If you prefer accelerating the cooling- down phase, 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.
CAUTION
The glass door handle reaches a temperature of approx. 150 °C / 302 °F.
Danger of burning.
 Use gloves or a tool (e.g. pincers) to open the glass door.
• When the inner chamber has cooled down to a value below 60 °C / 140°F, turn on the chamber (chap.
5).
Gas control (CO
2
, and O
2
(chamber with O
2
control) is deactivated during the sterilization cycle. To
activate gas control, the following conditions are required:
1. Confirming the information message “STERILIZATION FINISHED” with “Ok”
2. Aborting the still running hot-air sterilization cycle
3. Inner chamber temperature below 80 °C
If the temperature exceeds < 80 °C, gas control will remain deactivated even after confirming
the information message “STERILIZATION FINISHED” with “Ok” and aborting the sterilization
cycle.
Only after the temperature has decreased below 80 °C, gas control will turn on again.
18.3.6 Terminating the completed sterilization cycle
The effective sterilization phase (holding phase) is automatically finished after 4 hours. Then comes a
defined 6-hours cooling down phase until 37 °C / 98.6°F is reached. This entire sterilization cycle of 10
hours duration is followed by an equilibration phase of unlimited duration with a constant setpoint
temperature of 37 °C / 98.6 °F.
This symbol on the controller display indicates a successful hot-air sterilization.
The sterilization cycle is first in the cooling-down phase and after completing the sterilization
cycle in the subsequent equilibrating phase of 37 °C / 98.6°F.
To terminate the hot-air sterilization cycle before completing the entire cooling-down phase,
proceed as described in chap. 18.3.5.
