damaged by high temperatures. The filter prevents dust and particulates
from entering the electronics compartment. The fan filter can be cleaned,
but it can also be replaced as part of the FTIR maintenance kit. Use the
following procedure to periodically clean or replace the fan filter, which is
located on the left side panel of the analyzer.
Important Note Do not remove the screws that secure the fan filter
housing to the panel.
