Cutting through or kinking the capillary of the surface-mounting thermostats
will result in permanent instrument failure!
Minimum permissible bending radius of the capillary is 5 mm.
The temperature probe must be installed in JUMO pockets, otherwise the
approval of the surface-mounting thermostat becomes invalid.
The temperature probe must be completely immersed in the medium.
To ensure their overall response accuracy, the thermostats must only be used
in conjunction with the pockets supplied by the factory.
When used in air, a process connection without pocket must be chosen.
