The user is responsible for the installation of main shut-off valves at the site of installation. The
following main shut-off valves are required:
•

The main shut-off valves have to be easily accessible. They must close off the connections to the
corresponding media when needed. The main shut-off valves have to be lockable in their OFF
position in order to prevent accidental re-activation.
As the user is responsible for installing the main shut-off valves, he/she should also provide in-
structions how to operate the main shut-off valves properly.

Appropriate safety labels on the microscope warn users of hazards. Each safety label is
affixed close to the point where a particular hazard exists. Moreover, you will find several labels
