C 150 (E2) 12/2012 page 66/90
The precise duration of the entire sterilization cycle depends on the ambient temperature at the installa-
tion site and can thus vary. At an ambient temperature of 25 °C / 77 °F, the total duration is approx. 12
hours. You can shorten the cooling-down time by aborting the sterilization cycle (chap. 15.5) during the
cooling-down phase, i.e. no sooner than after 6 hours.
During sterilization, the CO
2
valve is closed and the CO
2
controller turns off entirely.
15.4.2 Procedure for hot-air sterilization:
Before carrying out the first hot-air sterilization, remove any protective lamination sheet from
the inner metal surfaces.
When starting a hot-air sterilization, CO
2
control automatically becomes inactive.
The safety controller settings are inactive during sterilization. They become functional again
following abortion of the sterilization and/or restart of the unit at the main power switch.
Turn off the unit
Pull out the CO
2
sensor without any rotation from the connection socket in the upper part of the rear
and remove it from the inner chamber.
The CO
2
sensor is temperature resistant up to a maximum temperature of 60 °C / 140 °F. It is
therefore required to remove it before performing a hot-air sterilization.
CAUTION
Excess temperature.
Damage to the CO
2
sensor.
Do NOT expose the CO
2
sensor to hot-air sterilization.
The CO
2
sensor head was especially adjusted for your specific chamber. To avoid confusion, an ad-
hesive label with a serial number is adhered to the sensor head. When exchanging the sensor, repeat
CO
2
control adjustment.
CAUTION
Different CO
2
sensor.
Invalid calibration.
Do NOT change the CO
2
sensor head.
Write to down the serial number of the CO
2
sensor.
Empty the water pan.
WARNING
Danger of implosion.
Damage to the unit.
Empty the water pan before starting the hot-air sterilization.
Clean the C 150.
Water pan and shelves must be inside the incubator, the water pan at its usual place on the bottom.
Close the inner glass door and the outer unit door.
Turn on the unit.
Activate the sterilization procedure: Press the controller button 180 °Cfor 3 seconds to access the
sterilization program.
