7.1 Assembly instructions
Before starting work:
• Read the operating instructions and, in particular, the safety information.
• Check the current system status, e.g., pressure, temperature, medium,
operating status.
• Clean, empty and/or depressurise the piping system.
• Disconnect pneumatic and electric connections from the actuator.
Caution – damage to components!
Installation of faulty or non-specified parts or using the same as replacement parts may
disable or disrupt functionality considerably.
– Only use parts and equipment approved by the manufacturer.
– After the work has been carried out, the function of the valve must be checked.
Warning – Welding hazards!
When dismantling valves or setting up a system, pipes must be welded. This can lead to
a fire. The fire can seriously injure people.
During disassembly/assembly, sharp-edged pipe ends may be present. The staff can cut
themselves at the sharp edges.
Welding or cutting pipes creates hot surfaces. These can lead to burns.
Therefore, please note the following before welding:
– Welding work may only be carried out by qualified personnel.
– Remove all flammable parts from the environment before welding.
– Cover combustible parts that cannot be removed.
– Prior to commencement of flame, welding, soldering and/or grinding operations,
approval must be obtained from the plant manager for open fire/welding work.
– Work only with a release certificate.
– Have fire extinguishing agents, e.g. powder extinguishers ready.
– Organize fire stations.
– Check the workplace for fire nests several times up to 24 hours after completion
of the work.
– Wear personal protective clothing during welding.
