GettingStarted

 PlacementofSystem.Placethesystem:
i)inaproperlyventilatedareaeitheroutdoorsorinaventilatedlaboratory
environmentthathasbeenapprovedbyyourlocalfiremarshal
ii)onalevelsurface
 MountingofComponents.Ensurethat:

i)allvesselsaresecurelymountedtothemountingrack
ii)themountingrackunionsareproperlytightened
iii)thecomponentsarelevel
iv)allwheelsonthemountingrackarelocked

 Chiller/HeaterOptions.Forhazardous(ClassI,Division1andClassI,
Division2locations)environments,bothaliquidheatsourceandcooling
sourcewillneedtobeplumbedintothehazardousarea.Thisisgenerally
donebyusingaheaterandchiller,andplacingtheminanareadetermined
tobefitbyyourlocalbuildingdepartment.Ifrequired,youmayhaveto
utilizeULlistedequipmentforthistask,andsubmitabuildingplantoyour
municipality.YoushouldspeaktoyourPrecision®ExtractionSolutions
technicalrepresentativetoensurethatyourcoolingandheatingoptionsare
adequateforseamlessoperationofthePX1systeminapassive
configuration.ThePX1V2016extractionsystemcomespreconfiguredwith
heatingandcoolingunitssuitableforthispurpose.

 SolventRequirements.ThePX1V2016extractionsystemisdesignedtobe
usedwitheithera100%butane,100%propane,oranyblendthereof.

CHAPTER3
PressureTesting

PressureTesting/PreparingtheEquipmenttoOperate

YourPX1unitcomesfactorytestedandinspectedforsustainedpressureholding
capabilities.However,shippingandmovingoftheunitmaycreatepressureleaks,aswell
drasticchangeintemperature.Itistheoperator'sresponsibilitytocheckforpressurefor
leakspriortooperation.

Tocheckthesystemforleaks,pleaseattachallthecomponentsandhose
assembliesperthedrawinginthismanual.Ifpressuretestingtheentiresystemnew,the
solventvesselistobeincluded.Iftestingthesystemafterthesolventtankhasbeenfilled,
pleasekeepallvalvesonthesolventvesselCLOSED.AllothervalvesshouldremainOPEN.

Attacha3/8"JIChosetothecollectionvessel,andwithallthevalvesopenonthe
system,bringthesystempressureto150PSIusingcompressedairviaanaircompressor.
EnsuretheventdownnipplesonthegaugesareOPENEDpriortoperformingapressure
test.Notetheactualreadingsofthepressuregaugesbytakingapictureforlater
comparison.Allowthesystemtositunder150PSIforatleast1hourifthisisasecondary
test(betweenruns)or24hoursifitisaprimarytest(yourfirstpressuretest).Ifany
differenceinpressureisnoticed,thereisaleak,andtheunitisunsafetooperate.

Leakscanbeidentifiedbyfillingaspraybottlewithsoapywaterandsprayingthe
suspectedareawheretheunitisleaking.Theleakcanbeidentifiedbythepresenceof
bubbles.Themostcommonareastheleakarethevalveseats(whichcouldneedtobere-
taped),thesightglasses(whichmayneedtobetightened).Before
adjusting/tightening/re-tapinganypiecesontheunit,thesystemmustbeventeddown
to0PSI.

Oncetheunithaspassedapressuretest,youarenowreadytocharge/fillthe
solventvessel.

Youwillneedtodoseveralotherproceduresinordertopreparethemachineto
run.First,inspectitsoverallcleanliness.Ingeneral,Precisionkeepsourequipmentasclean
aspossiblepostproduction,however,shippingandhandlingoftheequipmentcancause
contamination.Becauseyouaremakingafoodgradeproduct,itisyourresponsibilityto
ensureallsurfacesusedarecleanandsanitaryatalltimes.

hydrocarbonsolventsuppliertoprocuretheproperfittings.

TochargeyourPX1solventvessel,beginbyvacuumingthetankdownto-30in/hg
oruntilthevacuumpumpbottomsout.MakesuretoalsoputthelinefromforPX1solvent
vesseltothesolventsourcetankunderavacuumalso.Vacuumreadingmaybeslightly
differentdependingonatmosphericconditions.

Oncethetankhasbeenvacuumeddown,itwillneedtobecooled.Ifusinga
Precisioncryogenicchiller,turnonthechillerandallowthetanktocool.Dependingon
youratmosphericconditions,thesolventsourcetankmayneedtobewarmed.Thiscan
bedonebyplacingitinahotwaterbath.Youarenowreadytofillthetank.WARNING:
NEVERINTRODUCEBUTANEORPROPANEINTOTHESYSTEMWHILETHEVACUUM
PUMPISRUNNING.ALWAYSDISCONNECTTHEVACUUMPUMPPRIORTO
INTRODUCINGSOLVENT.

Ifyouwish,youmayalsofillthePX1solventvesselwithitdetachedfromthe
mountingrack,whilesittingonarefrigerantscale,althoughthisisnotnecessary.

Startingwithallvalvesclosed,openthevalveonthePX1solventvesselleadingto
thesolventsource.Youmaynowopenthevalveonthesolventsourcetank.Remain
present,notingtheflowrateintothePX1solventvessel.Fortheinitialfillofthesystem,
arefrigerantscaleshouldbeuse.BeforefillingdisconnectthesolventvesselfromthePX1
mountingrackandtarethescaleto0withthesolventvesselonthescale.Thesolvent
vesselshouldbefilledwithnomorethan22LBSofsolventforthePX1V2016model,and

PreparingtoOperate

PreparingtoOperate-Passive

YouarenowreadytopreparetooperateyourPX1V2016system.Pleaseselectthe
appropriatesizedmaterialcolumntomatchtheweightandvolumeofyourinputmaterial.
Ensurethatthereisa4"screenedgasketatthebottomofthematerialcolumnabovethe
reducer.Ensurethatyourmaterialcolumnisproperlymountedtothemountingrack.Fill
yourmaterialcolumnleavingabout1-2inchesofheadspaceatthetopofthecolumn.
Thepackingdensityofthematerialisattheoperator'sdiscretion.Attachthematerial
columncaptothetopofcolumn.

NOTE:IFYOUARENEWTOUSINGACLOSEDLOOPSYSTEM,ITISRECCOMENDED
THATYOUBYPASSTHEDEWAXINGCOLUMNUNTILYOUBECOMEMOREFAMILIAR
WITHTHEPX1.

Youarenowreadytoputyourfiltersinplace.Note:Thelipidfilteringcolumnsits
belowandisattachedtothecryocolumn.Thefilterisinsidethelipidfilteringcolumn(see
componentsdiagraminthismanual).

Filtrationcanbedonewithavarietyofdifferentfiltersandmediaviathelipid
filteringcolumn.Coffeefilters,aretheleastlikelytoclog,anditisrecommendedthatyou
usesingleordoubleunbleachedcoffeefiltersinthesystemuntilyoubecomemore
familiarwiththesystem.Formoreadvancedusers,Whatman™gradequantitativeand
qualitativefiltersmaybeabetteroption.Pleaseeducateyourselfonwhatgradeof
filtrationisbestforyourapplicationandyourdesiredendproduct.Formoreonfiltration,
pleaseseeourYouTubechannel.

Atthistime,attheoperator'sdiscretion,youmayalsofillyourexpansion/filter
columnwitha3Aor4Amolecularsieve,whichmaybepurchasedfromDeltaAdsorbents.

Atthispoint,youwillcommencerunningyourrecirculatingchiller(i.e.,theDFR-50
orDFR-80,deepfreezerecirculators,sometimesreferredtoas“chillers”).Attheoperator's
discretion,youmaycoolthesolventvesseltoyourdesiredtemperatureviathechiller.

CHAPTER6
RunningtheExtractor

Allvalvesshouldnowbeclosed.

Openthesiphontubevalveonthesolventvessel(leadingtothematerialcolumn)
andtheinletvalveonthematerialcolumn(locatedonthelid)allowingsolventtoflood
thematerialcolumn.ThematerialcolumnisfullwhenthepressureiswithinafewPSIof
thetankpressure.Youmaynowclosethesiphontubevalve.Besurethatwhenrunning
passiveyoursolventisnottoocold,otherwiseallpressurewillbelostandthesolventwill
notwanttomoveoutofthetank.

Whenthedesiredmaterialcolumnsoaktimehasbeenreached,begintoopenthe
inletvalvetothecryocolumn.Itiskeytoallowthesolventto“stall”inthedewaxing/cryo
columninordertoallowforproperlipidcoagulation.Startwithonehourandadjustfrom
there.Youwillbeabletoviewtheclarityoftheoutputmaterialthoughthesightglasses
onthecollectionvessellid.Youcanadjustthespeed,temperature,andfiltration
dependingonthedesiredendproduct.

Asthecollectionvesselfillswithsolvent,thepressurewillbegintorise,andthe
vacuumpressurewillbelessthanadequatetocontinuetopulltheremainingsolvent
thoughthefilters.

Atthispoint,youmayexperienceacompletestopofsolvententeringthe
collectionvessel.Inordertopulltheremainingsolventintothecollectionchamber,turn
ontheheatingsourceforthecollectionvesselandexpansionfilter/columnandturnon
thecryogenicstocoolyoursolventvessel,andopenallthepropervalvestobegin
recovery.Thetemperaturevariationwillpullthecollectionvesselbackintoavacuumand
allowtheremainingsolventtoenterthecollectionvesselandre-condense.Throttlingof
theinletvalveonthesolventvesselisnecessarytoachieveamaximumpressure
differentialbetweenyourcollectionvesselandsolventvessel.Thehigherthepressure
differentialbetweenthesetwovesselsduringyourrecoveryprocess,thefasteryour
ultimatepassiverecoverywillbe.

Moreadvancedusers,usingfinegradefiltration,mayalsoopttouseavaporassist
atthetopofthematerialcolumnifthepumpisinadequateatpullingthesolventthrough.
Thiscanbedonebyconnectinganyvaporportofthesolventvesseltothevaporinput
onthetopofthematerialcolumn.

NOTE:IMPROPERKNOWLEDGEOFPROPERFILTRATIONGRADESAND
APPLICATIONSCANLEADTOCLOGSINTHESYSTEM.STARTWITHCOARSE
