WARNING!
Physicalinjuriesanddamagetopropertyandthe
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosi-
ve, toxic, carcinogenic, radioactive), and also with refrigera-
tion 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.
▶
Wear the requisite protective equipment (see chapter 3.6
“Personal protective equipment”).
▶
With hazardous media, the drain valve may only be
opened for a short time so that the condensate can run out.
CAUTION!
Checking the screw connections
Due to the settling of the components on the glass indicator,
the screw connections must be checked as in chapter 5.2
“Mounting of models LGG-R, LGG-T, LGG-M”:
▶
Immediately after commissioning
▶
Repeat every 24 hours until each screw connection
retains its torque
