Recommended procedure:
Turn off the unit
Pull out the sensor
Spray the sensor head with alcohol or wipe it clean with a soaked cloth. Observe the reaction time of
the disinfectant used.
Before reinserting the CO
2
sensor, it must be completely dry.
The filter in the front of the sensor only needs replacing when damaged or dirty.
The CO
2
sensor head was especially adjusted for the specific chamber. To avoid confusion, an adhesive
label with a serial number is adhered to the sensor head. When exchanging the sensor, repeat CO
2
ad-
justment.
CAUTION
Different CO
2
sensor.
Invalid calibration.
Do NOT change the CO
2
sensor head.
 Write down the serial number of the CO2 sensor.
15.4 Hot-air sterilization at 180 °C / 356 °F
The very first sterilization after operation may cause an odor. This is not a quality defect. We
recommend ventilating well the room during sterilization.
15.4.1 Overview
Heating up Holding Cooling down
approx. 2
hours
4 hours approx. 6 hours
Sterilization cycle of approx. 12 hours
Figure 32: Set-point profile during the sterilization cycle
The C 150 can perform an automatically controlled hot-air sterilization cycle. This procedure will take
approx. 12 hours and consists of the following steps:
Heating up phase: The incubator heats up the inner chamber as fast as possible to the sterilization
set-point temperature
Holding phase: Constant sterilization set-point temperature
The sterilization set-point temperature is pre-set in factory to 190 °C / 374 °F. When this temperature
is reached, the holding phase begins. The duration of the holding phase is in total 4 hours. This en-
sures that 180 °C / 356 °F is maintained on all internal surfaces for at least 30 minutes.
Cooling down phase: until 37 °C / 98.6°F is reached.
When 37 °C / 98.6 °F ± 1 ° is reached, the display "End" in the lower controller display (Figure 36 page
68) indicates the end of the sterilization procedure.
