Power failure and power return are noted in the event list (chap. 15.3).
If during power failure the inner chamber temperature or the CO
2
/ O
2
concentration has fallen below the
alarm thresholds, confirm the alarms (e.g., tolerance range, safety controller). See chap. 11.3.

Performance when opening the door
When you open the door, CO

Turning on the chamber
After connecting the supply lines (chap. 4), turn on the chamber by its main power switch. The lit pilot
lamp shows the chamber is ready for operation.
When the main power switch is turned on and yet the controller display is dark, the display is in stand-by
mode. Press on the touchscreen to activate it.
Check that the CO
2
control is activated (chap. 6.8).
Chamber with active humidification:
Fill the freshwater bag (chap. 4.5). Check that the humidifying system is activated (chap. 6.8).
After the first turning on of the chamber or after an interruption of the power supply the relative
humidity will increase after a delay of about 20 minutes. During this period, the relative humidity can
drop considerably.
Chamber with O
2
control:
Check that the O
2
control is activated (chap. 6.8).
Warming chambers may release odors in the first few days after commissioning. This is not a quality
defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for
one day and in a well-ventilated location.
WARNING: If customer should use a BINDER chamber running in non-supervised
continuous operation, 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.
