ASSEMBLY
Safety Instructions
WARNING!
Danger of injury during assembly of the valve.
• Such work may only be performed by authorized service
personnel and using suitable tools!
• After an interruption of the electricity or compressed air
supply, ensure that the process is restarted in a defi ned
or controlled manner!
Fluid Installations
DANGER!
Danger from high pressure!
Working on the unit involves acute risk of injury.
• Cut off pressure before detaching lines and valves.
Before assembly
Any installation position, preferably with the actuator up-
wards.
→
Before assembly, remove contamination from pipes and
fl ange connections.
