WARNING
High concentration of inert gas.
Risk of death by suffocation.
∅
Do NOT set up units in non-ventilated recesses.
 Ensure technical ventilation measures.
 Respect the relevant regulations for handling these gases.
 When decommissioning the vacuum drying oven, shut off the inert gas supply: Close
valve (6).
Install a pressure reducer for inert gas operation. Set the pressure reducer to a pressure slightly above
ambient pressure. Ensure that the pressure reducer will open. Do not change this setting in order to avoid
perturbation inside the oven and release of big quantities of inert gas after flooding the VDL.
Following evacuation, an inert gas, e.g., nitrogen, is led into the inner chamber via the fine dosing valve for
inert gas (6), until pressure compensation with the atmosphere occurs. Depending on the individual appli-
cation, you can perform a second evacuation and repeat the inert gas flooding.
When the inert gas fine dosing valve is open, a maximum of approx. 0.6 m³/h gas flows into the inner
chamber. The introduction of inert gas by under-flooding in the lower region of the inner chamber rear wall
and the extraction at the inner chamber ceiling allow an effective inert gas flushing.
