1! Begin!O2!Concentrator!Testing! Start!the!diagnostic!process!for!a!work!order!on!O2!Concentrator.!
2! Does!the!machine!power!up?! With!unit!plugged!in,!and!power!switch!turned!on,!the!display!should!light!up!and!compressor!should!run,!making!noise.!
3! Is!the!inlet!filter!in!place?! Some!models!require!the!compressor!inlet!filter!to!be!in!place!in!order!for!machine!to!start.!For!all!other!models,!proceed!to!step!5.!4! Install!inlet!filter! If!available,!install!the!foam!inlet!filter.!
5! Troubleshoot!the!power!supply!(separate!chart)! Use!a!multimeter!at!the!leads!of!the!compressor!to!ensure!that!sufficient!voltage!is!reaching!the!machine.!!If!insufficient,!there!may!be!a!problem!with!the!wiring!or!fuse.!See!flowchart!on!Power!Supply!and!BTA!skills!on!Power!Supply.!
6! Does!the!alarm!sound!during!power!up?! Both!display!lights!and!an!audible!alarm!should!sound!after!power!switch!is!turned!on.!
7! Replace!9V!battery! Unplug!machine,!ensure!current!battery!has!correct!polarity,!and!replace!with!a!new!battery!if!necessary.!!


8! Does!the!pump!create!a!sufficient!flow?!
Flow!is!identifiable!by!the!floating!ball!in!the!flow!meter!and!by!bubbles!in!the!humidifier.!To!check!if!there!is!sufficient!flow,!remove!humidifier!and!place!finger!at!air!outlet.!When!outlet!is!covered,!the!ball!should!fall!down.!When!outlet!is!unobstructed!the!ball!should!float.!When!flow!rate!is!set!to!highest!setting!(5!liters!per!minute)!the!ball!should!be!at!its!highest!level!in!flow!meter.!!


9! Is!the!compressor!functioning!correctly?! Check!voltage!into!leads!of!compressor,!and!then!check!flow!rate!at!exit.!If!the!compressor!is!not!producing!max!flow!rate!at!sufficient!voltage!(120V),!the!compressor!is!not!functioning!correctly.!(Proceed!to!13)!10! Clean!inlet!filter! Foam!inlet!filter!should!be!cleaned!weekly!by!washing!with!soap!and!water.!Ensure!filter!is!dry!before!




replacing.!See!BTA!skills!on!Filters!(Plumbing)!!
11! Ensure!that!correct!sized!tubing!is!used!and!that!connections!are!tight.!


Check!that!the!diameter!of!all!O2Ycarrying!tubing!matches!the!machine!inlet!diameters.!Ensure!that!all!connections!are!tight.!Also!ensure!that!the!tubing!being!used!cannot!diffuse!O2.!!See!BTA!skills!on!Connections!(Plumbing)!
12! Look!and!listen!for!leaks!in!tubing! While!air!is!flowing,!listen!for!sound!of!escaping!O2!and!run!hand!over!tubing!to!feel!stream.!If!holes!exist,!tube!should!be!replaced,!not!patched.!See!BTA!skills!on!Leaking!(Plumbing)!
13! Clean!all!O2Ycarrying!tubing! Dirt!or!water!droplets!could!block!the!airway.!See!BTA!skills!on!Blockages!(Plumbing)!14! Clean!compressor! See!BTA!skills!on!cleaning/lubricating!(Motors)!
15! Defective!Compressor:!Consider!replacing! If!compressor!is!clean,!and!is!still!not!producing!correct!flow!rate!it!is!probably!faulty!and!needs!to!be!replaced.!
16! Is!the!O2!Concentration!over!60%?! See!BTA!skills!for!Oxygen!Concentration!Measurement!(MechanicalYCalibration)!
17! Has!the!zeolite!canister!expired?! Zeolite!canisters!should!be!replaced!every!25,000!hours.!The!granules!start!black!and!appear!gray!when!they!are!no!longer!efficient!for!use.!
18! Replace!if!possible! If!available,!replace!expired!zeolite!canisters!with!new!granules.!
19! Check!tubing!for!kinks!or!blockages! Ensure!that!all!O2Ycarrying!tubes!are!elongated!and!not!twisted!or!bent.!See!BTA!skills!on!Blockages!(Plumbing)!
20! Check!for!restrictions!in!muffler!and!resonator.!! A!restricted!muffler!would!prevent!waste!gas!from!exiting!the!system!freely.!Disconnect!the!muffler!and!operate!unit!to!see!if!this!fixes!concentration.!
21! Defective!part:!Consider!replacing!PC!board.! PC!board!could!have!tears!or!kinks!that!may!be!irrecoverable.!!
22! Does!the!machine!run!without!overheating!and!making!excessive!noise?! The!unit!should!not!feel!hot!to!the!touch!or!make!loud!excessive!noises.!
23! Ensure!exhaust!vent!is!at!least!3”!from!wall.! The!exhaust!pipe!should!be!far!enough!away!from!external!obstructions!that!the!waste!gas!can!flow!freely!into!the!atmosphere.!
