1.Scope of Supply
 Electrically heated muffle furnace with
 Controller B410
 Integrated processdocumentation

2.Defined Application
 The furnace had been designed for preheating or ashing in air.
 Only materials with known characteristics and melting temperatures may be used. Check the material safety data sheets if necessary.
 Use of the furnace for any other purpose whatsoever such as processingproducts other than those intended or handling hazardous substances orsubstances posing a health hazard constitutes improper use and must be agreed upon with Nabertherm.
 Operating the furnace with explosive gases or mixtures, including explosive gases ormixtures created as a result of heating/drying, is prohibited.

 This furnace features nosafety technology for processes which produce combustiblemixtures, for example debinding.If the furnace is still used for such processes despite this fact, the concentration of organicgas mixtures in the furnace must never exceed 3% of the lower explosion limit (LEL). Thispre-requisite applies not only to normal operation but, in particular, to exceptionalsituations such as process disruptions (caused, for example, by the failure of a power unit).You must ensure that the furnace is adequately ventilated and vented.
 Do not open the furnace when it is hot. If thefurnace must be opened at high temperaturesreduce this time to the minimum possible.Wear protective clothing and provide sufficientroom ventilation.
 Discolourations may occur on the stainlesssteel housing (especially when the hot furnaceis opened); these, however, do not affect thefunction.
