The furnace will have been installed by an Agilent field service
engineer during installation of the instrument. However, if you have
removed the furnace to replace the electrodes or clean the sample
compartment, reinstall the furnace workhead as follows:
1 Ensure that both the spectrometer and GTA control unit are
switched off.
2 Remove the left panel on the instrument. To do this, lift the
bottom of the panel upward and then pull it forward (see
Figure 4).
