● WheninstallingCentralStationEXinahospitalorotherfacilitywhereelectromagneticwavesare

generatedfromnearbymedicaland/orelectronicdevices,bepreparedfornoiseandelectronic

interferenceElectromagneticInterference(EMI).Donotinstallwherethewavescandirectlyradiate

intotheelectricalbox,controllercable,orcontroller.Inverters,appliances,high-frequencymedical

equipment,andradiocommunicationsequipmentmaycausetheproducttomalfunction.

Theoperationoftheproductmayalsoadverselya󰀨ectthesesamedevices.Installtheproductat

least3mawayfromsuchdevices.

● Whenawirelesscontrollerisused,locateitatadistanceofatleast1meterbetweentheindoor

unitandelectriclighting.Ifnot,thereceiverpartoftheunitmayhavedi󰀩cultyreceivingoperation

● Donotinstalltheunitinanylocationwhereanimalsandplantscancomeintodirectcontactwiththe

outletairstream.Exposurecouldadverselya󰀨ecttheanimalsandplants.

● Donotinstalltheunitinanyplacewhereoilcanseepontotheunits,suchastableorseatingareasin

restaurants,andsoforth.Fortheselocationsorsocialvenues,usespecializedunitswithoil-resistant

featuresbuiltintothem.Inaddition,useaspecializedceilingfandesignedforrestaurantuse.These

specializedoil-resistantunitscanbeorderedforsuchapplications.However,inplaceswherelarge

quantitiesofoilcansplashontotheunit,suchasafactory,eventhespecializedunitscannotbeused.

Theseproductsshouldnotbeinstalledinsuchlocations.

Installation Precautions

Takethefollowingprecautionstoreducetheriskofelectricshock,reor

explosionresultinginseriousinjuryordeath:

● WheninstallingCentralStationEXinto…

▫ Awall:Makesurethewallisstrongenoughtoholdtheproduct’sweight.Itmaybenecessaryto

constructastrongwoodormetalframetoprovideaddedsupport.

▫ Aroom:Properlyinsulateanyrefrigeranttubingruninsidearoomtoprevent“sweating”thatcan

causedrippingandwaterdamagetowallandoors.

● DonotinstallCentralStationEXinthefollowingplaces.Doingsocanresultinanexplosion,re,

damage,corrosion,orproductfailure.

▫ Explosiveorammableatmosphere

▫ Whereare,oil,steamorpowdercandirectlyentertheunit,suchasnearbyorabovea

kitchenstove.

▫ Whereoil(includingmachineryoil)maybepresent.

▫ Wherecorrosivegasessuchaschlorine,bromine,orsuldecanaccumulate,suchasnearahot

tuborhotspring.

▫ Wheredense,salt-ladenairowisheavy,suchasincoastalregions.

▫ Wheretheairqualityisofhighacidity.

▫ Whereharmfulgasescanbegeneratedfromdecomposition.

● Performatestruntoensurenormaloperation.Safetyguards,shields,barriers,covers,andprotective

devicesmustbeinplacewhilethecompressor/unitisoperating.Duringthetestrun,keepngersand

clothingawayfromanymovingparts.

● Cleanupthesitewhennished,rememberingtocheckthatnometalscrapsorbitsofwiringhave

beenleftbehindinsidetheunitbeinginstalled.

Afterinstallationworkforthesystemhasbeencompleted,explainthe“SafetyPrecautions”,theproper

useandmaintenanceofCentralStationEXtothecustomeraccordingtotheinformationinallmanuals

thatcamewiththesystem.Allmanualsandwarrantyinformationmustbegiventotheuserorleftnearthe

Electrical Precautions

Takethefollowingprecautionstoreducetheriskofelectricshock,reor

explosionresultinginseriousinjuryordeath.

● Highlydangerouselectricalvoltagesareusedinthissystem.Carefullyrefertothewiringdiagram

andtheseinstructionswhenwiring.Improperconnectionsandinadequategroundingcancause

serious injury or death.

● Beforeservicing,openandtagalldisconnectswitches.Neverassumethatelectricalpoweris

disconnected.Checkwithmeterandequipment.

● Onlyuseelectricalprotectionequipmentandtoolssuitedforthisinstallation.

● UsespeciedcablesbetweenCentralStationEXandthepowersupply/airconditioner/external

equipment.

● Shieldedcommunicationcableisnotalwaysrequiredbutstronglyrecommendedtoprevent

communicationissuesforapplicationssuchas:HeavyandLightIndustrialBuildings,Telecom

Centers,DataCenters,Airports,RadioStations,Hospitals/Healthcarebuildings,andO󰀩ces.

● Useadedicatedpowersupplyfortheairconditionerattheunit’sratedvoltage.

● Besuretoinstallcircuitbreakers(groundfaultinterrupter,isolatingswitch,moldedcasecircuit

breakerandsoon),withthespeciedcapacity.Ensurethatthewiringterminalsaretightenedsecurely

torecommendedtorquespecications.

● Clampelectricalwiressecurelywithacableclampafterallwiringisconnectedtotheterminalblock.

Inaddition,runwiressecurelythroughthewiringaccesschannel.

● Wheninstallingthepowerlines,donotapplytensiontothecables.Securethesuspendedcablesat

regularintervals,butnottootightly.

● TurnOFFanddisconnectCentralStationEXfromthepowersourcewhenwiring.

DonotopenthebackcoverwithoutturningOFFthemainpowersupply.

● Donotcleanwith,orpourwaterinto,CentralStationEXasitcouldcauseelectricshockand/or

damagetheproduct.Donotusestrongdetergentsuchasasolvent.Cleanwithasoftcloth.

● Checkthatthegroundcableissecurelyconnected.Donotconnectgroundwiringtogaspiping,water

piping,lightningconductor,ortelephonegroundcables.

● Iftherearefrequentoccurrenceswithblownfusesorippedcircuitbreakers,shutdownthesystem

immediatelyandcontactyourservicecontractor.
