General safety notes
The equipment is not applicable for heating, drying or conditioning of specimen which is intrinsically
explosive, flammable or toxic or, which may liberate hazardous substances under normal
operating temperature conditions!
The equipment is intended for heating, drying, conditioning of specimen which may liberate steam or
other gas mixture. This leads to potential hazards of high temperatures, fire, fume and the
general hazards related to the application of electrical energy.
Further hazard sources may arise from the type of material being treated and by the fracture of the
container and other glass vessels.
It is not possible to cover all possibilities; they remain largely within the responsibility and the
judgment of the operator!
The equipment must only be used as intended and described in these Operating Instructions. This
includes operation by suitably trained qualified personnel.
The maximum temperature deviation both in normal condition and in electro-magnetic interference
field according to IEC 61326-1 is ±0.5 °C.
