VD (E2.1) 07/2017 page 10/96
Any solvent contained in the charging material must not be explosive or inflammable. I.e., irrespective of
the solvent concentration in the steam room, NO explosive mixture with air must form. The drying
temperature must lie below the flash point or below the sublimation point of the charging material.
Familiarize yourself with the physical and chemical properties of the charging material, as well as the
contained moisture constituent and its behavior with the addition of heat energy and changes in pressure.
Familiarize yourself with any potential health risks caused by the charging material, the contained
moisture constituent or by reaction products that may arise during the drying process. Take adequate
measures to exclude such risks prior to putting the chamber into operation.
DANGER
Electrical hazard.
Danger of death.
∅ The oven must NOT become wet during operation or maintenance.
The chambers were produced in accordance with the relevant VDE regulations and were routinely tested
in accordance to VDE 0411-1 (IEC 61010-1).
During and shortly after operation, the temperature of the inner surfaces almost equals the set-point.
CAUTION
The inner chamber will become hot during operation.
Danger of burning.
∅ Do NOT touch the inner surfaces or the charging material during operation.
In the case of operation with inert gas, the chamber is supplied with an oxygen-displacing gas (e.g. N
2
).
The gas emerging from the system must therefore be removed from the installation area by means of a
suitable extraction system (see technical ventilation measures in the DGUV guidelines 213-850 on safe
working in laboratories (formerly BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the
employers’ liability insurance association) (for Germany).
With use of a vacuum system or a vacuum pump, observe the permitted gas inlet
temperature. Observe the safety instructions of the pump manufacturer.
