G3621a/p Stack Gas Oxygen Analyzing System 6 Commissioning 6.1 Installation and Setup Pre-checks After completing the installation and before starting the system for the first time, please check the following: Check and confirm that all electrical connections are carried out according to the manual.
Routine Maintenance 7 Routine Maintenance Warning The sensor/probe is hot and can cause severe burning of personnel if not handle with care. Turnoff the analyzer before working with the probe and sensor. Before removing the probe from the stack, make sure that there is no over-pressure or hot exhaust gas inside the stack.
G3621a/p Stack Gas Oxygen Analyzing System 7.3 Diffusion Probe The probe filter is normally cleaned by automatic backflushing. The period between backflushing’s is determined by the setup and should be set and changed according to the actual flue gas condition and how dirty the filter gets. Regular backflushing will normally keep the filter clean.
Page 24
Routine Maintenance Turn off the analyzer and remove the blue cover plate of the probe. Unplug the sensor connection. Loose the sensor from the probe head by using a spanner and pull out the sensor. Screw a new sensor into the probe and set the sensor plug to the sensor connector. Then close the cover plate.
