4. Insert the flue probe into the sample hole of the device under test. The
probe tip should be in the middle of the flue pipe or exhaust stream.
Ensure the In-Line Filter / Water Trap hangs below the analyzer in the proper
vertical position when readings are being taken. Failure to comply reduces
the effectiveness of the water trap and may result in damage to the instru-
ment. Refer to the pictures below for correct and incorrect use.
WARNING: - Should the CO reading rise above 2,000ppm the probe should
immediately be disconnected from the instrument and the instrument
returned to a clean air environment. This ensures the analyzer will not be
subjected to an abnormally high concentration of CO, and will protect the
sensors.
Make sure to check the water trap periodically during testing to ensure it
does not fill with condensate and empty it as necessary. If the filter begins to
fill during a test, open the lid and empty out the condensate. After closing the
lid, allow readings to stabilize again.
IMPORTANT: The water trap is fitted with a water block filter (p/n A794W) in
the lid to prevent water from flowing down into the pump. If the water trap
fills the water block filter will stop the flow to the analyzer and the pump will
slow and no longer pull a sample. The water trap should be emptied immedi-
ately if this happens. The water block filter may need to be dried out
or replaced before testing can resume.
