Refrigerant Precautions
Toreducetheriskofseriousinjuryordeath,thefollowingrefrigerant
precautionsmustbefollowed.
Asoriginallymanufactured,thisunitcontainsrefrigerantinstalledbyJohnsonControls.Johnson
Controlsusesonlyrefrigerantsthathavebeenapprovedforuseintheunit’sintendedhomecountry
ormarket.JohnsonControlsdistributorssimilarlyareonlyauthorizedtoproviderefrigerantsthat
havebeenapprovedforuseinthecountriesormarketstheyserve.Therefrigerantusedinthisunit
isidentiedontheunit’sfaceplateand/orintheassociatedmanuals.Anyadditionsofrefrigerantinto
thisunitmustcomplywiththecountry’srequirementswithregardtorefrigerantuseandshouldbe
obtainedfromJohnsonControlsdistributors.Useofanynon-approvedrefrigerantsubstituteswillvoid
thewarrantyandwillincreasethepotentialriskofinjuryordeath.
Ifinstalledinasmallroom,takemeasurestopreventtherefrigerantfromexceedingthemaximum
allowableconcentrationintheeventthatrefrigerantgasesshouldescape.Theinstallationshould
meettherequirementsinASHRAEStandards15and34.Ifrefrigerantgashasleakedduringthe
installationwork,ventilatetheroomimmediately.
Checkthedesignpressureforthisproductis601psi(4.15MPa).Thepressureoftherefrigerant
R410Ais1.4timeshigherthanthatoftherefrigerantR22.Therefore,therefrigerantpipingfor
R410AshallbethickerthanthatforR22.Makesuretousethespeciedrefrigerantpiping.Ifnot,the
refrigerantpipingmayraptureduetoanexcessiverefrigerantpressure.Besides,payattentionto
thepipingthicknesswhenusingcopperrefrigerantpiping.Thethicknessofcopperrefrigerantpiping
differsdependingonitsmaterial.
TherefrigerantR410Aisadopted.Therefrigerantoiltendstobeaffectedbyforeignmatterssuch
asmoisture,oxidelm,(orfat).Performtheinstallationworkwithcaretopreventmoisture,dust,or
differentrefrigerantfromenteringtherefrigerantcycle.Foreignmattercanbeintroducedintothecycle
fromsuchpartsasexpansionvalveandtheoperationmaybeunavailable.
Toavoidthepossibilityofdifferentrefrigerantorrefrigerantoilbeingintroducedintothecycle,the
sizesofthechargingconnectionshavebeenchangedfromR407CtypeandR22type.Itisnecessary
topreparetheappropriatetoolsbeforeperforminginstallationwork.
UserefrigerantpipesandjointswhichareapprovedforusewithR410A.
Acompressor/unitcomprisesapressurizedsystem.Neverloosenthreadedjointswhilethesystemis
underpressureandneveropenpressurizedsystemparts.
Beforeinstallationiscomplete,makesurethattherefrigerantleaktesthasbeenperformed.If
refrigerantgasesescapeintotheair,turnOFFthemainswitch,extinguishanyopenamesand
contactyourservicecontractor.Refrigerant(Fluorocarbon)forthisunitisodorless.Iftherefrigerant
shouldleakandcomeintocontactwithopenames,toxicgascouldbegenerated.Also,becausethe
uorocarbonsareheavierthanair,theysettletotheoor,whichcouldcauseasphyxiation.
Wheninstallingtheunit,andconnectingrefrigerantpiping,keepallpipingrunsasshortas
possible,andmakesuretosecurelyconnecttherefrigerantpipingbeforethecompressorstarts
operating.Iftherefrigerantpipingisnotconnectedandthecompressoractivateswiththestop
valveopened,therefrigerantcyclewillbecomesubjectedtoextremelyhighpressure,whichcan
causeanexplosionorre.
Tightenthearenutwithatorquewrenchinthespeciedmanner.Donotapplyexcessiveforcetothe
arenutwhentightening.Ifyoudo,thearenutcancrackandrefrigerantleakagemayoccur.
Whenmaintaining,relocating,anddisposingoftheunit,dismantletherefrigerantpipingafterthe
compressorstops.
Whenpipesareremovedoutfromunderthepipingcover,aftertheinsulationworkiscompleted,
coverthegapbetweenthepipingcoverandpipesbyapacking(eld-supplied).Ifthegapisnot
covered,theunitmaybedamagedifsnow,rainwaterorsmallanimalsentertheunit.
Donotapplyanexcessiveforcetothespindlevalveattheendofopening.Otherwise,thespindle

otherwise,thesedeviceswillbedamaged.(Itisclosedbeforeshipment.)
Ifthearrangementforoutdoorunitsisincorrect,itmaycauseowbackoftherefrigerantandresultin
