6 Assembly and installation
6.1 Safety instructions
Hazardous situations during installation can be avoided by safety-conscious and
proactive behaviour of the personnel.
For installation, the following principles apply:
• Only qualified personnel are allowed to set-up, install and commission the
component.
•
Ensure that adequate working and traffic areas are available at the place of
installation.
• Observe the maximum load-bearing capacity of the installation surface.
• Observe the transport instructions and markings on the part(s) to be
transported.
•
Remove any nails protruding from transport crates immediately after opening
the crate.
• Under no circumstances should anyone stand under a suspended load.
•
Safety devices of the component may not work effectively during installation.
• Reliably secure sections of the plant which have already been connected
against inadvertently being switched on.
6.2 Notes on installation
The valve is normally installed in upright position. Care must be taken to ensure
that the valve housing, the pipe system, and the leakage cavity can drain
properly.
If the valve is installed in the horizontal position, pay attention that the vent hole
in the actuator is aligned horizontally on one side.
To prevent damage, make sure that:
• the valve is installed in the pipe system free of tension and
•
no foreign materials (e.g. tools, bolts, lubricants) are left in the system
6.3 Valve with Detachable Pipe Connection Elements
This section describes the procedure to fit the valve.
Caution!
Liquids in pipes

► Therefore, before releasing any pipe connections or hinged clamps: drain
the pipe and, if necessary, clean or rinse it.
► Separate the pipe section in which the valve is to be fitted from the rest
of the piping system to prevent product entering again.
