6.1.2 Installing the instrument
WARNING!
Risk of burns!
The cooling element can be hot as a result of previ-
ous use. Allow the cooling element to cool before-
hand.
■ 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 flats provided for this purpose and
using a suitable tool.
When there is a cooling element, the lower hexagon should
be used for tightening (see figure 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.
