vibration.
Mount the Detector more than 15 m

temperature. See technical specification.
Install the flange more than 75 mm (3 in)
from the extraction point.
Exceed the maximum probe
temperature. See technical specification.
Site the analyser where the ambient
temperature is less than 0 ºC (32 ºF) or
greater than 45 ºC (113 ºF).
The probe must be situated where the
temperature will not exceed the rating of
the sample line. Unless cabinet heaters
or coolers are provided.
Install the probe where the filter can be
eroded by coal dust.
