Termination of warranty!
Using chlorinated tap water or additives that
contain chlorine will void the manufacture
warranty. Similarly, the use of ultrapure water
whose conductivity is out of the range of 1 to
20

Starting operation
Starting and loading the device:
1. Fill the water tray with up to max. 3.0 l of processed water. Do not exceed
the upper level mark.
2. Make sure that the CO
2
supply system valve is open.
3. Turn the device on using the power switch.
4. Set nominal values for temperature and CO
2
content on the operating
panel.
5. Ventilate work space by leaving both device doors open until acoustic alarm
sounds.
6. Start device using auto-start routine.
7. Close device doors.
8. The temperature control adjusts the temperature to the set nominal value,
the humidity rises.
9. When the temperature and relative humidity are constant, automatic adju-
stment of the CO
2
measuring system is performed.
10.The ”auto-start” indicator goes off.
11.The CO
2
control supplies the set amount of CO
2
.
12.The device is ready for operation.
13.Load work space with cultures.
NOTE – Duration of the auto-start routine
When the device is cold and when the ambi-
ent temperature is low, the auto-start routine
may take up to 10 hours.
NOTE – Loading
To ensure sufficient air circulation and even
heating of the samples, the loading surface
within the work space should be used up to 70
% max. Large objects in the work space that
dissipate heat may impair heat
distribution.
