Toreducetheriskofseriousinjuryordeath,thefollowinginstallation
precautionsmustbefollowed.
Wheninstallingtheunitinto…
Awall:Makesurethewallisstrongenoughtoholdtheunit’sweight.Itmaybenecessaryto
constructastrongwoodormetalframetoprovideaddedsupport.

Damporunevenareas:Usearaisedconcretepadorconcreteblockstoprovideasolid,level
foundationfortheunittopreventwaterdamageandabnormalvibration.
Anareawithhighwinds:Securelyanchortheoutdoorunitdownwithboltsandametalframe.
Provideasuitablewindbafe.
Asnowyarea:Installtheoutdoorunitonaraisedplatformthatishigherthandriftingsnow.
Providesnowprotectionhood.
Iftheremotesensorsarenotusedwiththiscontroller,thendonotinstallthiscontroller…

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.
WhenR410Aisused,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tosuch
partsastheexpansionvalvecausingoperationalissues.
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verifytheappropriatetoolsareonhand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properlyandthecompressorstartswith
thestopvalveopened,airmaybepulledintothesystemand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withadditionalinsulatingmaterial(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excessiveforcetothestopvalvewhenopening.Ifdamaged,thestopvalvecouldcome
apartduetorefrigerantpressure.Atthetestrun,fullyopenthegasandliquidvalves,otherwise,

VRF Air Conditioners
Johnson Controls proudly introduces new Variable Refrigerant Flow (VRF) air conditioners, a highly-efcient
and reliable air-conditioning system. Recently, increased numbers of buildings are requiring "intelligent"
facilities that include communication networks, ofce automation, and a comfortable environment. In
particular, a comfortable environment is becoming more of a year-around requirement in ofce buildings.
The VRF multi-split system air conditioner meets these requirements. The proven combination of the scroll
compressor and inverter provides the best air conditioning for small and medium ofce buildings.
VRF System
Johnson Controls has developed the VRF system with its customers in mind.
This system, allows the interconnection of indoor units for all our VRF air conditioners.
This system provides the consumer with greater exibility for installation, which means that the air-
conditioning systems will integrate better within complex facility structures.

2.3.1 General Data
NOTES:
*1. Nominal capacity is based on combinations within the VRF system under the following conditions:
Cooling Operation Conditions
Indoor Air Inlet Temperature: 80°F DB (26.7°C DB)
67°F WB (19.4°C WB)
Outdoor Air Inlet Temperature: 95°F DB (35.0°C DB)
Heating Operation Conditions
Indoor Air Inlet Temperature: 70°F DB (21.1°C DB)
Outdoor Air Inlet Temperature: 47°F DB (8.3°C DB)
43°F WB (6.1°C WB)
Piping Length: 24 ft. 7-3/16 in. (7.5m) Piping Lift: 0ft. (0m)
*2. The sound pressure level is based on the following conditions.
4.9 ft. (1.5m) beneath the units.
The above data was measured in an anechoic chamber so that reected sound should be taken into consideration in the eld.
*3. For the (H,Y)IDH series, the fan speeds are only “High” and “Low”. Therefore, the fan speed indication of the LCD is changed as
High → Low , by pressing the fan speed key “
” or “ ”.
If one wired controller is connected to multiple indoor units (included with 3 or 4 taps speed of the indoor unit), the fan speed
indication of LCD is changed as (High 2 →) High → Medium → Low . However, the actual fan speed is as shown in the table
below.
