4.3 Operating Tips
• When an analyzer s brought n from a cold vehcle, let t warm up
slowly to mnmze condensaton. Temperatures below freezng wll not
damage the analyzer; however, brngng a cold analyzer nto a warm,
humd envronment may cause condensate to form nsde the case.
• If the CO channel (Fyrte Tech 60) s set up for Auto Zero (refer to Sec-
ton 3.5.3), ensure that the analyzer s samplng fresh ar when turned
ON. Pulling a flue-gas sample through the analyzer during its warm-
up perod wll not damage the analyzer, but t wll result n ncorrect
CO readngs. Also note that a CO sensor error wll occur f the detect-
ed CO level s above 50 ppm durng warm-up.
• For analyzers that are used to measure flue-gas, note that flue-gas
condensate s acdc and very corrosve. It s mportant not to allow
the analyzer’s nternal components to become soaked n condensate for
long perods of tme.
• Before each use, inspect the filter element of the water-trap / filter as -
sembly. Replace the filter if it looks dirty.
• When sampling flue-gas, keep the analyzer above the water-trap, and
keep the trap n a vertcal poston. Ths wll maxmze the effectve-
ness of the trap and keep lqud condensate from beng drawn drectly
nto the analyzer.
• When lqud condensate s seen nsde the water trap, empty the trap
before t becomes full. Refer to Secton 5.6.
• It is recommended that the analyzer be purged after taking a flue-gas
measurement before turnng t OFF. Once the probe s removed from
the stack, dsconnect the hose assembly from the bottom of the analyz-
er and let the pump run for 10 mnutes or so to completely remove any
remaining flue gases and dry any condensate from inside the sensor
chamber.
• When storng the analyzer, t’s a good dea to empty the water trap and
leave t open to further dry t out.
• Calbrate the analyzer every 6 months to ensure ts accuracy.
