CAUTION
Refer to Figure 2-3 for disassembly of the spectrometer header.
6. Loosen screws (10X) and remove spectrometer header from spectrometer body. The
vacuum system vents to atmosphere as the screws are loosened. Retain the socket head
cap screws and Belleville washers. Maintain correct orientation of Belleville (conical)
washers when removing.
7. Remove the spectrometer header. Rest upside-down on the four posts sticking up from the
printed circuit board.
8. Remove metal gasket and discard. Do not scratch the mating surface when removing the
gasket. To prevent scratching of any sealing surface, do not use metal tools for this task.
Do not attempt to reuse the gasket.
9. Examine the spectrometer cavity for discolored areas. If the inside of the spectrometer
body appears dirty, clean it with Vac-u-solv spectrometer cleaning kit (Agilent part number
670029096).
