1.1 General safety notes
The units are designed for operation with non-flammable liquids to DIN EN 61010-2-010.
A laboratory thermostat is intended for heating, cooling and pumping liquids according to the needs of the user. This
leads to hazards by high or low temperatures, fire, and the general hazards due to the application of electrical energy.
The user is largely protected through the application of the appropriate standard specifications.
Further hazard sources may arise from the type of material being thermostated, for example by exceeding or undercut-
ting certain temperature thresholds or by the fracture of the container and reaction with the heat transfer liquid.
It is not possible to cover all possibilities; they remain largely within the responsibility and the judgement of the operator.
The unit must only be used as intended and as described in these Operating Instructions. This includes operation by suit-
ably instructed qualified personnel.
The units are not designed for use under medical conditions according to DIN EN 60601-1 or IEC 601-1!
