If no CO
2
concentration is indicated (display showing “ – – – – ”) the CO
2
sensor is not con-
nected.
Note when setting high gas concentrations
Carbon dioxide (CO
2
) in high concentrations is hazardous to health. It is colorless and almost odorless
and therefore practically imperceptible. Any CO
2
gas that may escape must be safely led out via good
room ventilation or a suitable connection to an exhaust system. We recommend installing a CO
2
warning
system.
DANGER
Danger of suffocation and poisoning by high concentration of CO
2
(> 4 Vol.-%).
Death by suffocation.
∅
Do NOT set up chambers in non-ventilated recesses.

Ensure technical ventilation measures.

Observe the relevant regulations for handling CO
2
.
If CO
2
is released, leave the area und inform the security service or fire department.
8. Placing samples in the incubator
In order to detect possible transport damages we recommend a 1 or 2 days test run at the desired set-
points before placing valuable samples. Then you can load the chamber with the samples.
WARNING: If customer should use a chamber running in non-supervised continuous opera-
tion, we strongly recommend in case of inclusion of irrecoverable specimen or samples to
split such specimen or samples and store them in at least two chambers, if this is feasible.
During the equilibration phase of approx. 2 hours after turning on the chamber, undefined temperature
and CO
2
conditions occur within the chamber. During this phase, do not place any sample materials in
the chamber.
HINWEIS
Danger of undefined temperature and CO
2
conditions in the equilibration phase.
Destruction of samples.

Load the chamber only after equilibration of temperature and CO
2
.
Do not exceed the maximum load of each shelf and the permitted total load (see chap.26.4).
