2.6. Special conditions for safe use (X conditions)

Pressure surges must be avoided at all costs. Open the shut-off valves slowly.
„
Temperature increases due to compression warming absolutely must be taken
„
into account. In these cases it may be necessary to throttle the rate of change
of pressure or reduce the permissible medium temperature.
The end user must ensure that the instrument is connected to the equipotential
„
bonding of the end-use application via the process connection.
Avoid handling substances that might react dangerously with the materials of
„
the instrument.
Avoid handling substances that are liable to spontaneous combustion.
