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. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.

CAUTION!
Damage to the instrument
To avoid possible damage to gas density indicator or to test equipment,
follow the steps below:
▶
▶

▶
▶
1. Seal the sealing faces.
2. At the mounting point, screw the gas density indicator in hand-tight.
▶
When screwing in, do not cross the threads.
3. Tighten with a torque spanner using the spanner flats.

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.
Make sure the threaded connections are clean and undamaged.
The maximum permitted torque of the thread is 13.5 Nm = 10 ftlbs. This
permitted torque must NEVER be exceeded.
The instrument should be installed in such a way that process-related
electrostatic charges (e.g. caused by flowing media) can be excluded.
The case is rotatable by 330°. When turning do not touch the display.
If the message "OL" is displayed, the measuring range has been
exceeded and the pressure source must be removed immediately to
prevent damage to the internal sensor.
