Warnings
• If you turn off the analyzer or the process is shut down, turn off the
aspirator air to avoid plugging problems.
• The outside of the sensor cover and all sensor assembly components
are extremely hot (up to 500°F (260°C) inside the cover), even after a
considerable period from shutdown. Turn off the power to the sensor
and control unit when working inside the sensor. Use caution and wear
appropriate gloves when handling components.
• Be extremely careful when performing maintenance on the sensor
while the process is running, especially if the process is under signifi -
cant positive pressure. Removing any part of the sensor plumbing can
allow process gases and gases of high temperature to escape into the
sensor.
Cautions
•
• Always use a backup wrench when working on sensor plumbing. This
helps to prevent damaging welds and distorting sensor plumbing.
• Never use pipe dope or any other contaminant that gives off combus -
tible vapor on any joints of the sample tubing. Combustible vapor in
the sample tubing can lead to erroneous readings.
