Loading

Without technical ventilation the chamber must not be loaded with material containing sol-
vents.
The chamber cannot be loaded when turned off / in standby mode .
Before loading the material to be loaded, note:
When loading the chamber also in the context of intended use, an explosive mixture may form in the wor-
king space. Therefore, a safety area of at least. 1 m in front of the oven must be considered.
• Ensure equipotential bonding. The accessible installation and operating surface of the equipment must
be conductive. This installation and operating surface must be connected with the vacuum drying oven
according to the grounding plan (Chap. 6.6).
• The personal protective equipment (PPE) of the operating personnel must be implemented ESD pro-
tected. This applies also to gloves.
• Activate the technical ventilation (extraction):
The operator shall provide active ventilation (technical ventilation according to country-specific regula-
tions (TRBS 2152 Part 2 for Germany) prior to commissioning of the chamber. It must include the enti-
re installation area of the vacuum drying oven; in addition, extraction must be provided on the floor
behind the chamber. Loading must take place under technical ventilation in the safety area in front of
the oven.
• Introduce only those solvents for which the auto-ignition temperature and the maximum drying tempe-
rature (safety temperature) have been determined and setting on the saftey controller has been per-
formed.
• Acc. to IEC 60079-0, only substances with an auto-ignition temperature above 200 °C / 392 °F may be
introduced into the chamber. This chamber is NOT suitable for drying substances with an auto-
ignition temperature below 200 °C.
Explosion or implosion hazard and danger of poisoning by introduction of unsui-
table loading material.
Serious injury or death from burns and / or explosion pressure or by poisoning.
∅ Do NOT introduce any substance with an auto-ignition temperature below 200 °C /
392 °F into the chamber.
∅ Do NOT introduce any substance which is combustible or explosive at working tempe-
rature into the chamber.
∅ Do NOT introduce energy sources such as batteries or lithium-ion batteries into the
chamber.
∅ Do NOT introduce any substance, which fall under the explosives law into the chamber
∅ Do NOT introduce any combustible dust into the chamber.
∅ Do NOT introduce any substance which could lead to release of toxic gases into the
chamber.
If the auto-ignition temperature of a solvent contained in the drying material is exceeded during the drying
process, there is an immediate risk of fire and explosion. Make sure that the auto-ignition temperature of
a solvent contained will NEVER be reached.
