Safety Information
The lines may only be used after installation by qualified personnel in accordance with the corresponding installation instructions. Use for the manufacture of commercial goods is only permitted in certified countries. Otherwise, the product may only be used for testing purposes.
Note on PPH2 lines: For use with dry hydrogen only, in accordance with DIN EN 17124 (3.7 or higher). Due to the risk of corrosive effects, contact with moisture and/or water on the inner surface of the line must be strictly avoided under all circumstances.
