Deactivating the ISE unit
If you intend not to use the ISE unit for more than one week, you should deactivate it.
This saves ISE fluids and reduces wear and tear of the tubing, and lowers the
likelihood of malfunctions and errors occurring.
This situation may occur, for example, if you need close the laboratory temporarily,
or if you want to relocate the Cedex Bio instrument with the ISE unit.
