System Maintenance

Changing the air filters

To make sure that the electrical components in the spectrometer are properly
cooled, the air filters must allow sufficient air into the instrument. Check the
filters regularly and change them if they are dirty.
You should not need to change the filters more than once every year if the
environmental conditions are as described under Chapter 6, Laboratory
Requirements.
Replacement filters are available; see Chapter 5, Parts and Supplies for the part
number.
1. Carefully pull off the snap-on plastic grid that holds the air filter in place.
2. Replace the filter and push the grid back into place.
