WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
flammable or toxic substances), harmful media (e.g. corro-
sive, toxic, carcinogenic, radioactive), and also with refrige-
ration plants and compressors, there is a danger of physical
injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
5.1 Mounting instructions for instruments with EHEDG and 3-A
Observe the following instructions, especially for EHEDG-certified and
3-A-compliant instruments.
Mount the instrument with minimal dead space and able to be
■
cleaned easily.
The mounting position of the instrument, welding socket and instru-
■
mentation T-piece should be designed to be self-draining.
The mounting position must not form a draining point or cause a basin
■
to be formed.
Mounting position with slight downward inclination so that the
■
cleaning agents wet all parts and run off cleanly.
With the process connection via an instrumentation T-piece, the
■
