pan and start cleaning the incubator.
3.
Only water or mild detergent should be used.
4.
During cleaning pay attention not to damage the temperature and CO
2
sensors in the chamber.
5.
Having finished cleaning, you should allow the chamber to dry completely.

Disinfection of the CO
2
sensor
17.3.
To ensure proper disinfection and operation of the CO
2
sensor, VWR recommends wiping the sensor head with pure alcohol
or a non-corrosive, acid and chlorine-free alcohol based surface disinfectant.
Use only the detergents or disinfectants recommended by VWR. Other products are not approved, since they could in
particular damage the CO
2
sensor.
Advice on how to safely store the unit
18.
1.
Close the CO
2
pressure cylinder valve and disconnect the CO
2
gas hose.
2.
Remove load from the chamber.
3.
Clean the chamber and empty the water pan.
4.
Before disconnecting the unit from the mains, the chamber
must be dried
(e.g. by door opening, chamber ventilating
or chamber heating without the water pan). Turning the unit off without drying will cause water condensation in CO
2
sensor and its malfunction.
5.
Disconnect the incubator from the mains.
6.
Leave the inner/ outer doors and access port open to allow adequate ventilation.
7.
Store in temperature between 10°C and 50°C and relative humidity maximum of 70%.
To maintain the proper function of the CO
2
sensor, never spray the sensor with any cleaning detergents
or disinfectants. Generally perform any disinfection only when the chamber is turned off. The sensor may be
only superficially disinfected with a damp cloth. The hot air sterilization routine is intended for a through
sterilization of the entire chamber.
NOTICE: Danger of damage to the CO
2
sensor due to unsuitable disinfection procedures.
NEVER spray the disinfectant directly on the CO
2
sensor. Wipe the sensor with a lint-free cloth soaked with
the disinfectant.
