instrument without the filters will put the analyzer at high risk to damage the
pump and sensors. These filters should be replaced as needed.
3. The built-in thermoelectric chiller removes moisture from the stack gas as it
enters the analyzer, and the automatic condensate drain pump sends
accumulate condensate out the bottom of the analyzer. It is best to let the
E8500 Plus run with the main gas pump on for at least a few minutes after
measuring is done to let all of the condensate automatically drain out of the
analyzer and to also fully purge the stack gases out of the unit.
4. Do not expose the probe tip to open flame.
5. Do not rest the stack probe’s sampling line on a hot boiler surface.
6. Allow the probe tip to cool off and the instrument to aspirate clean air before
packing the probe.
7. It is strongly recommended to use single span calibration gas mixtures,
preferably with balance nitrogen when calibrating the sensors for the most
precise calibrations.
8. Keep the analyzer upright in the protective carrying case with the LCD display
facing up for best operations of the unit.
WARNING: Never lay the E8500 Plus on its side with the display screen
& keypad upside down.
9. If the analyzer enclosure if ever unscrewed and taken apart, be careful when
pulling the top piece off the bottom piece because there is a ground wire
connecting the two main pieces. Do not over-tighten the screws that hold the
two main enclosure pieces together.
