and connected to earth. This ensures that the strainer
is included in the system's equipotential bonding.

of application (see 2). Always observe the pressure
and temperature limits stated on the type plate as well
as all other technical data and safety information
during device installation, commissioning and
operation.
Always observe national and international regulations
concerning the operation of devices and systems
under pressure.
Prior to installation, the operator has to ensure that
the pressure bearing parts have not been damaged
during transportation.
The devices have to be installed, operated and
serviced by qualified personnel. The operator has the
responsibility to ensure that the personnel have
received sufficient and appropriate training. In cause
of doubt, please contact the manufacturer.
