Instruction 0024-9435 19Fyrite Tech4.3 Operating Tips• When an analyzer is brought in from a cold vehicle, let it warm up slowlyto minimize condensation. Temperatures below freezing will not dam-age the analyzer; however, bringing a cold analyzer into a warm humidenvironment may cause condensate to form inside the case.• If the CO channel (Fyrite Tech 60) is set up for Auto Zero (refer to Sec-tion 3.5.3), ensure that the analyzer is sampling fresh air when turnedON. Pulling a flue-gas sample through the analyzer during its warm-upperiod will not damage the analyzer, but it will result in incorrect COreadings. Also note that a CO sensor error will occur if the detected COlevel is above 50 ppm during warm-up.• For analyzers that are used to measure flue-gas, note that flue-gascondensate is acidic and very corrosive. It is important not to allow theanalyzer's internal components to become soaked in condensate for longperiods of time.• Before each use, inspect the filter element of the water trap / filter assem-bly. Replace the filter if it looks dirty.• When sampling flue-gas, keep the analyzer above the water-trap, andkeep the trap in a vertical position. This will maximize the effectivenessof the trap and keep liquid condensate from being drawn directly into theanalyzer.• When liquid condensate is seen inside the water trap, empty the trapbefore it becomes full. Refer to Section 5.6.• It is recommended that the analyzer be purged after taking a flue-gasmeasurement before turning it OFF. Once the probe is removed from thestack, disconnect the hose assembly from the bottom of the analyzer andlet the pump run for 10 minutes or so to completely remove any remain-ing flue gases and dry any condensate from inside the sensor chamber.• When storing the analyzer, it's a good idea to empty the water trap andleave it open to further dry it out.• Calibrate the analyzer every 6 months to ensure its accuracy.
