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
