- the first lid 120 is then put back in place.
- the inner element 104 is replaced by a spare inner element of same size and shape.
- the plugs 154 of the first inner element may be removed, to allow the electrical resistances 152 to be pushed out of the boreholes 147.
- the electrical resistances 152 are then inserted into the boreholes 147 of the spare inner element, before said spare inner element is inserted in the inner chamber 113 through the first opening 116.
- the electrical resistances 152 are replaced by spare electrical resistances embedded in the spare inner element.
- the helical crest 146 is in contact with the inner wall 112, in order to seal the helical path 151.
- the removal of the inner element 104 may cause frictions due to the cylindrical shapes of the inner wall 112 of the outer body and of the lateral wall 138 of the inner element
- the frustoconical shapes of the inner wall 212 of the outer body and of the lateral wall 238 of the inner element allow an easier removal, with a lower level of friction.
