Assembly and maintenance instructions - 481/681, 482/682
• Only use the valve:
- for the intended purpose
- in satisfactory condition
- with respect for safety and potential hazards.
• Always observe the installation instructions.
• Standards DIN EN 806-2 and DIN 1988-200 must be considered and applied to
the use of pressure reducing valves.
• 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 responsible
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.
