General Notes of Safety
• Only use the valve:
- for the intended purpose
- in satisfactory condition
- with respect for safety and potential hazards.
• Use only for gases and liquids compatible with the materials used.
• Always observe the installation instructions.
• To ensure correct use always make sure to only install the pressure reducer
in places where the operating pressure and temperature do not exceed the
design criteria on which the order is based. The manufacturer shall not be re-
sponsible for damage caused by outside forces or other external influences!
Hazards at the pressure reducer caused by the flow medium and operating
pressure are to be avoided through appropriate measures.
• All assembly work is to be carried out by authorized specialist staff.
• If the medium leaks at the secondary pressure relief, ensure that there is no
risk to persons or the surrounding area.
