The drying and heating ovens FED do not dispose of any measures of explosion protection.
DANGER
Explosion hazard.
Danger of death.
∅
Do NOT introduce any substance into the heating oven which is combustible or
explosive at working temperature.
∅
NO explosive dust or air-solvent mixture in the inner chamber.
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 temperature
inside the chamber 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.
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 temperature process. Take
adequate measures to exclude such risks prior to putting the drying and heating ovens into operation.
DANGER
Electrical hazard.
Danger of death.
∅
The unit must NOT become wet during operation or maintenance.
The drying and heating ovens were produced in accordance with the 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, the exhaust duct, the door window (option), the door gaskets,
and the access ports will become hot during operation.
Danger of burning.
∅
Do NOT touch the inner surfaces, the exhaust duct, the door window, the access ports,
the door gaskets, or the charging material during operation.
1.6 Intended use
The drying and heating ovens FED are suitable for drying and heat treatment of solid or pulverized
charging material, as well as bulk material, using the supply of heat. The solvent content must not be
explosive or flammable. A mixture of any component of the charging material with air must NOT be
explosive. The operating temperature must lie below the flash point or below the sublimation point of the
charging material. The drying and heating ovens FED can be used to dry e.g. glassware.
Other applications are not approved.
The drying and heating ovens FED are not classified as medical devices as defined by the Medical
Device Directive 93/42/EEC.
Do NOT use the unit for drying processes when large quantities of vapor would form and result in
condensation.
