8. Calibrate the PID prior to use after the 5minute warm up periods ends.To clean the lamp1. Follow the directions above to remove thelamp from the instrument.2. Make sure your hands are clean.3. Coat the cotton swab in a thin layer of lampcleaning powder of 0.1 to 0.25 m -alumina.4. Pick up the lamp with the other hand. Do nottouch the top of the lamp window with barefingers.5. Using the cotton swab dipped in the cleaningpowder, polish the top of the lamp with aswirling motion. Cleaning typically takesabout 30 seconds and is finished when theswab starts to squeak.6. Reassemble the sensor and the PHD6. Seesteps 2-8 above in the directions to replacethe stack or lamp.6.5 Sample probe assemblyThe PHD6’s sample draw probe is the standardprobe assembly from Honeywell Analytics. Theillustration below gives a breakdown of all parts inthe sample draw probe with part numbers. Thesample probe handle contains moisture barrierand particulate filters designed to removecontaminants that might otherwise harm theinstrument.Sample probe filters should be replacedwhenever visibly discolored due tocontamination.CAUTION: Never perform remote samplingwithout the sample probe and hose assembly.The sample probe handle contains replaceable29filters designed to block moisture and removeparticulate contaminants. If the pump isoperated without the probe assembly in place,contaminants may cause damage to the pump,sensors and internal components of the PHD6.Particulate contaminants are removed by meansof a cellulose filter. The hydrophobic filterincludes a Teflon barrier which blocks the flowof moisture as well as any remaining particulatecontaminants.6.5.1 Changing sample probe filtersThe threaded sample probe handle is accessesthe filters. The particulate filter is held in place bymeans of a clear filter cup. To replace theparticulate filter, remove the old filter and cup,insert a new filter into the cup, and slide the cupback into place in the probe handle. Thehydrophobic barrier filter fits into a socket in therear section of the probe handle. (The narrowend of the hydrophobic barrier filter is insertedtowards the rear of the handle.)To avoid accidentally introducing particulatecontaminants into the system, turn the sampleprobe upside-down prior to removing either thehydrophobic filter or the particulate filter.The following replacement filter kits are currentlyavailable from Honeywell Analytics:#Particulatphobic#Hydro-Part No. Kit54-05-K0401 Standard 10 354-05-K0402 Economy 10 054-05-K0403 Economy 30 1054-05-K0404 Bulk 0 2554-05-K0405 Bulk 100 06.5.2 Changing sample probe tubes (wands)The standard 11.5” long butyrate probe tube isheld in place with a hex-nut compression fittingand compression sleeve. The standard probetube can be interchanged with other customlength sections of 1/4” OD tubing, or probe tubesmade of other materials (such as stainless steel).Probe tubes are exchanged by loosening thehex-nut compression fitting, removing the oldtube, sliding the compression sleeve into placearound the new tube, inserting the new tube intothe probe handle, then replacing and tighteningthe hex-nut.Note: The sample probe must be checkedfor leakage (as discussed in Section 3.1.1)whenever filters or probe tubes areexchanged or replaced before beingreturned to service.6.6 PHD6 Pump MaintenancePHD6 pumps are fairly maintenance free with theexception of the replacement of the pump filterson a regular basis.
6.6.1 Replacing pump filters1. Remove the two screws that hold the inletport to the pump.2. Gently pull the dust filter holder free of thepump.3. Remove and replace the dust filter that islocated in the holder.4. The hydrophobic filter is located beneath theinlet port in the pump housing. Use a smallscrewdriver or other object to punch throughthe filter and remove it. The gasket that sitsbetween the inlet port and the filter shouldcome out with the filter.5. Place the new hydrophobic filter with the filterside down in place of the one removed instep 4. The gasket should be located on topof the filter and should sit against the dustfilter holder, which will be reinstalled in step6.6. Replace the dust filter holder (which now hasa new filter in it) and secure it with the twoscrews removed in step 1.30
