the protective packing.

Mount the replacement filament on the ion source. Slide the filament
assembly toward the setscrews so that the plate of the filament assembly is
parallel to the plate of the ion source.
Note
Do not twist the filament assembly, otherwise the ionization chamber will
be deformed.

Mount the 3 nuts on the setscrews and tighten them with the special socket
wrench.

Grip the U-sections with flat-nose pliers, introduce the electrical connections
of the filament laterally at the U-sections and tighten the screws.
The dust filter at the air intake must be cleaned whenever there is clearly visible
contamination. Use a vacuum cleaner to extract the dust from the filter. For this
work it is not necessary to detach the QME from the QMA
WARNING
Do not forget this cleaning, even if the unit is installed in such a way that the
contamination cannot be easily seen.
For cleaning the housing use only a piece of cloth lightly moistened with water, and
possibly some dishwashing detergent.
