NOTE: Performapreliminaryleakcheckatthecylinderneckwithasoapsolution(SwageLokSnooporequivalent)
onceithasbeenfilledhalfwaywithargon.Ifaleakisdetected,discontinuethefillforthatparticular
cylinder.
Verifythecontainerbyensuringthatthefinalfillpressureisasdetailedaboveat59°F(15°C).Ifrequired,
refertothepressurevs.temperaturechartforIG‐541inAppendixA.2.
Closevalvebyunscrewingthecentralscrewonthefillingadaptorandremovethetophalfoftheadaptor.
Noticethedowelontheinternalpieceofthefillingadaptormovedownwardsduringthisoperation.
ProceedwithremovalofthebottomhalfofthefillingadaptorbyunscrewingthetwoM6setscrews.Remove
thisadaptorfromvalveandcheckthatthespringwasherhasdroppedlowerthanitsoriginaldepth.
Ventthefillinghoseandcheckthatthereisnoflowfromthevalveoutlet.
Fitthevalvelockoutassembly ontothevalve(Figure4.2.3‐1)priortoremovingthefillinghose.
Removethefillinghoseandscrewtherecoilcapontothedischargeoutlet.
Removethevalvelockoutassemblyfromthevalveaftertherecoilcaphasbeenfitted.
Proceedtoleakchecking(Section5).
Checkthecontainerpressure(Section6).
Oncetestingiscomplete,screwthesh ipping/safetycapontothecylinder.
