Replacing the External Filter
If a filter is dirty or clogged, remove it by unscrewing it from the black gas inlet adapter on the
front of the instrument. Discard it and replace it with a new filter (P/N: 008-3022-000). Perform
a pump stall test to make sure the inlet and the external filter are installed properly so that there
are no leaks in the system.
IMPORTANT!
An AreaRAE Plus/Pro must not be calibrated or operated without a filter. Operation without a
filter may damage the instrument.
