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 must be installed so that the housing can drain on its own.
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.
•
the valve is installed so that the flow is directed against the valve disc.
•
the valve is ideally installed in vertical position.
