SEQUENCE OF OPERATION
Verification of Battery Free Power Loss Alarm
CheckthePerfecto2concentratorforproperoperatingconditions.
1. Iftheunithasbeeninbelow‐freezingtemperatures,allowittowarmuptoroom
temperaturebeforeoperating.
2. Theconcentratormayneedtobeturnedonforfourtofivesecondstochargethe
BatteryFreePowerLossAlarm.Connectpowercordtooutletandturnthe
concentratoron.Turnflowcontrolknobcounterclockwiseandflowwillbegin
IMMEDIATELY.SetflowratetofiveL/min.Lettheunitrunfor30minutes,thenturn
unitoff.
3. UnplugthepowercordandpressOn/Off( )switchtotheOn()position.An
intermittentaudiblealarmwillsound.ThisconfirmsproperoperationoftheBattery
FreePowerLossAlarm.TurnOn/OffswitchOff( ).
4. Connectpowercordtooutletandturnonconcentrator.Unitwillbeeponstart‐up.
5. Checktheoxygenconcentrationperspecificationsafter30‐40minutesrunningtime.
Sequence of Operation
TurningOn()thepowerswitchapplies120VACtothecompressormotor,hourmeter,
transformer,coolingfanandtheprintedcircuit(P.C.)board.
Roomairentersthecompressorviathecabinetfilterandthecompressorinletfilter.The
airiscompressedbythewobblepistonsinthecompressortoapressureof21p.s.i.(144.79
kPa).
Asincreasedpressurecreatesincreasedtemperature,aheatexchangerisusedtolower
thetemperaturebeforetheairentersthe4‐wayvalve.Itisthenchanneledtoasievebed
containingtheadsorptionmaterial.Restrictiondownstreamofthesievebedcauses
pressuretobuild
upinsidethesievebedwhichisnecessaryfortheadsorptionprocess.A 
smallamountofrelativelypureoxygenentersthetopofthesecondbedthrougha
restrictiveleakinthepressureequalization(P.E.)valvewiththebalanceenteringa
storagetank.Thenitrogenremovedisexhaustedbackfromthebedthroughthe4‐way
valveintoroomair.Amufflerislocatedattheexhaustendofthevalvetomufflethe
soundoftheexhaustasitexitstheconcentrator.
Theoxygennotbeingusedtoexhaustischanneledintothestoragetank.Thepressurized
oxygenisregulateddowntofivep.s.i.(34.4kPa),entersanaccurateflow‐measuring
device,flowsthroughOutletHEPAfilterandcheckvalve,thenouttothepatient.
