6.1.2 Installing the instrument
WARNING!
Risk of burns!
The cooling element can be hot as a result of previous use. Allow the cooling
element to cool beforehand.
GB
When screwing the instrument in, the force
required to do this must not be applied through
the case or the cap ring, but only through the
spanner lats provided for this purpose and
using a suitable tool.
When there is a cooling element, the lower
hexagon should be used for tightening (see
igure a "Mounting cooling element")
The correct torque depends on the dimensions
of the process connection and the gasket used
(form/material).
When screwing in, do not cross the threads.
For heat dissipation, the cooling element must
not be insulated.
If the instrument is mounted upside down, it
must be ensured that no water can collect on
the electrical connection and on the cap ring.
Water can block the pressure compensation
diaphragm.
