6.2 - SPECIFIC SAFETY INSTRUCTIONS FOR THE INSTALLATION STEP

WARNING!

Before proceeding with installation, make sure that the upstream and downstream valves installed on the

line are shut off.

WARNING!

Installation may also take place in areas where there is a risk of explosion, which implies that all necessary
prevention and protection measures have to be taken.
For these measures, please refer to the regulations in force at the place of installation.
