5. Start up
After connecting the electrical supply (chap. 4.1), turn on the chamber by the main power switch (1).
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.
