WARNING!
Before storing the instrument (following operation),
remove any residual media. This is of particular impor-
tance if the medium is hazardous to health, e.g. caustic,
toxic, carcinogenic, radioactive, etc.
The use of liquid damping is always recommended for
temperatures near the dew point (±1 °C around 0 °C).
6. Commissioning, operation
When screwing the instrument in, the force required to do this must
not be applied through the casing, but only through the spanner flats
provided for this purpose and using a suitable tool.

When using thermowells, they must be filled with a thermal contact
medium in order to reduce the heat transfer resistance between the
outer wall of the sensor and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.
WARNING!
Do not fill hot thermowells. There is a risk of the oil
spraying out!
