The furnace of the analyzer is fitted with an automatic furnace cleaning system with thermal
shield .

As a result, the springs at the top of the furnace are released and the knurled nuts can be
easily unscrewed.
2. Turn the main switch on the analyzer to Position 0 and pull out the power plug.
3. Wait until the furnace of the analyzer has cooled down sufficiently.
