there is no restrictive statement from the health authorities concerning danger
to health in the event of short-term exposure at low concentration, for
example, should the measuring system fracture.

3. Mounting / General information
Capillary / temperature probe / pocket
General information
■ If the capillary of the surface-mounting thermostat is cut through or becomes
kinked, this could result in permanent device failure!
■ The minimum bending radius allowed for the capillary is 5 mm.
■ JUMO pockets must be used when installing the temperature probe, if the approval
for the surface-mounting thermostat is to remain valid.
■ The temperature probe must be fully immersed in the measurement medium.
■ When air is the measurement medium, you must choose a process connection
without a pocket.
■ To ensure the general accuracy of the operating value, the instruments must only
be used with the pockets supplied on delivery (diameter D = 8, 10 mm).
■ Only a probe of diameter d = 8 mm may be used in pockets of D = 10 mm.
■ Multiple assignments of pockets are only allowed with 2 or 3 cylindrical probes of
Ø 6 mm and pockets of 15 x 0.75 mm.
■ If two probes are assigned, the spring clip provided on delivery must be installed in
the pocket.
■ With pockets 22, 32, 41, 42 and 45 made from St 35.8I/16Mo 3 materials, the
allowed operating period at operating temperatures above 420°C is limited to
200,000 hours. Compliance with TRD 508 is essential for applications in this range.
