WARNING:Thissection
containsimportantinformation
regardingtheuseofthisregulator
withenrichedairnitrox.Donot
usethisregulatorwithenriched
airnitroxifyoudonotfully
understandthissection.Todo
otherwiseputsyouatrisk
ofseriousinjuryordeath.
WARNING: Obtainan
enrichedairnitroxdiving
certication.Inordertofully
understandtherisksinvolvedwith
divingelevatedpercentagesof
oxygen(above21%),youmust
obtainacerticationinenriched
airnitroxfromarecognized
trainingagency.
YourXSScubaregulatorhasbeen
preparedforusewithenriched
airnitrox(EAN)wheretheoxygen
percentagedoesnotexceed
40%(EAN40).Thisisbecause
yourregulatorwasbuilttoahigh
standardofcleanlinessusingEAN
compatiblepartsandlubricant.
Ifitisyourintentiontouseyour
newXSScubaregulatorwithEAN
upto40%O2,itiscriticalthatyou
maintaintheinternalcleanliness
ofyourregulator(seesectionon
CareandMaintenance).
Ifitisyourintentiontouseyour
regulatorinterchangeablywith
breathingair,thebreathingair
shouldbe“oxygen-compatible”
or“hyper-ltered”whereasthe
condensedhydrocarbonsinthe
Enriched Air Nitrox Use

airdonotexceed0.1mg/m3.
YourlocalXSScubaDealercan
helpyoudeterminewhetherthe
breathingairtheyprovidemeets
thiscriterion.
Standardcompressedbreathing
air,oftenreferredtoas“Grade
E”doesnotnecessarilymeet
thiscriterion.GradeEbreathing
airmaycontaincertainlevelsof
hydrocarbons,includingtraces
ofcompressoroils,thatwhilenot
consideredharmfultobreathe,
canposeariskinthepresenceof
elevatedoxygencontent.
Passinghydrocarbonsthrough
avalveandregulatorcreates
acumulativeeffectwherethe
hydrocarbonsbuildupovertime
alongtheinternalpassageways
oftheequipment.Whenthese
hydrocarbonscomeincontact
withhighpressureoxygen
enrichedair,theycanposea
veryrealhazardthatcanleadto
combustion.
Therefore,ifaregulatorhasbeen
usedwithGradeEbreathingair,
itshouldreceiveoverhaulservice,
includinghydrocarboncleaning,
priortobeingputbackintonitrox
service.
Althoughsecondstage
componentsarenotsubjected
tohighpressureEAN,XSScuba
recommendsthatthesame
guidelinesapply.

Venturi Lever
Youwillnoticealeverontheside
ofthesecondstageoppositethe
hoseconnection.Movingthis
leverbackandforthchangesthe
directionoftheairinternallyin
thesecondstage.Whenpulled
back,towardsyourmouth,to
theplus“+”setting,theairow
createsa“venturi”effectwhich
createsaniceboostinbreathing
performance.Whenmoved
forward,awayfromthemouth,
totheminus“-”setting,the
venturieffectisinterruptedwhich
increasesyourbreathingeffort.
Thedeeperyougo,themore
noticeablethisbecomes.
Itisimportanttonote,thatwhen
theleverisontheplus“+”setting
andtheregulatorisoutofyour
mouth,thesecondstagecanget
bumpedandgointoafreeow
condition.Shouldthishappen,just
movethelevertotheminus“-”
positionandthefreeowwillstop.
NOTE:Thesimplestwayto
usethisperformancefeatureis
toplacetheleverintheplus“+”
positionwhentheregulatorisin
yourmouthandmoveittothe
minus“–”positionwhenitisout
ofyourmouth.

TheInhalationControlKnob,
locatednexttotheventurilever
oncertainmodelsecondstages,
adjuststheeffortrequiredto
initiatetheinhalationcycle.Asitis
turnedin(clockwise),theopening
effortwillincrease.Thiswillmake
thesecondstagelesssensitive
tosuddenchangesinambient
pressure.
Turningtheknob“out”(counter-
clockwise)willdecreasethe
openingefforttomakebreathing
easier.Sometimesaslighthissing
maybeheardinthissetting.Ifthis
occurs,turntheknobclockwise
justenoughtostopthehissing.
Inhalation Control Knob

www.XSscuba.com
TheInhalationControlKnob
isparticularlyusefulatdeeper
depths,orinvariableconditions
thataffecttheopeningeffortof
thesecondstage,suchasfacing
intostrongcurrentsorwhileusing
adiverpropulsionvehicle(DPV).
Itwillalsoallowcompensation
foradifferenceinthehydrostatic
pressurebetweenyoursecond
stageandthecenterofyour
lungs,suchaswhenyouarein
ahead-downposition.Youcan
usetheInhalationControlKnob
totuneyourregulatortomaintain
itspeakperformancethroughout
thecourseofyourdive,or
youcanleaveitsetinitsmid-

Care and Maintenance
Assoonaspossibleafterthedive,
itisimportanttosoakorrinseyour
regulatorinfreshwater.Warm
water(<120°F/49°C)isbest.
Thebestmethodistosoakit
inatubofwaterwhileitisstill
connectedtothecylinderand
pressurized.Thiskeepsrinse
wateroutofthehosesandthe
rststage.
Ifthisisnotpossible,then
youmaysoakitwhileitis
depressurizedaslongasyou
followthesesteps:
•Ensurethatthedustcapis 
makingawatertightsealover
theregulator’sinlettting.
