Takethefollowingprecautionstoreducetheriskofpropertydamage.
● Preventmoisture,dust,ornoncondensablecompoundsfromenteringtherefrigerantcycleduring
installationwork.Foreignmattercoulddamageinternalcomponentsorcauseblockages.
● Ifairltersarerequiredonthisunit,donotoperatetheunitwithouttheairltersetinplace.Iftheair
lterisnotinstalled,dustmayaccumulateandbreakdownmayresult.
● Donotinstallthisunitinanyplacewheresilicongasescancollect.Ifthesilicongasmoleculesattach
themselvestothesurfaceoftheheatexchanger,thennedsurfaceswillrepelwater.Asaresult,any
amountofdrainagemoisturecondensatecanoverowfromthedraincondensatepanandcouldrun
insideoftheelectricalbox,possiblycausingelectricalfailures.
● Wheninstallingtheunitinahospitalorotherfacilitywhereelectromagneticwavesaregenerated
fromnearbymedicaland/orelectronicdevices,beawareofnoiseandelectronicinterference
ElectromagneticInterference(EMI).DonotinstallwhereEMI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unittomalfunction.Theoperationoftheunit
mayalsoadverselyaffectthesesamedevices.Installtheunitatleast10ft.(approximately3m)away
fromsuchdevices.
● Whenawirelesscontrollerisused,locateatadistanceofatleast3.3ft.(approximately1m)between
theindoorunitandelectriclighting.Ifnot,thereceiverpartoftheunitmayhavedifcultyreceiving
operationcommands.
● 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affecttheanimalsandplants.
● Donotinstalltheunitwithanydownwardslopetothesideofthedrainadapter.Ifyoudo,youmay
havecondensateowingbackwhichmaycauseleaks.
● Besurethecondensatehosedischargeswaterproperly.Ifconnectedincorrectly,itmaycauseleaks.
● 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ventilationunit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.
● Ifthewiredcontrollerisinstalledinalocationwhereelectromagneticradiationisgenerated,make
surethatthewiredcontrollerisshieldedandcablesaresleevedinsideconduittubing.
● Ifthereisasourceofelectricalinterferencenearthepowersupply,installnoisesuppression
equipment(lter).
● Duringthetestrun,checktheunit’soperationtemperature.Iftheunitisusedinanenvironment
wherethetemperatureexceedstheoperationboundary,itmaycauseseveredamage.Checkthe
operationaltemperatureboundaryinthemanual.Ifthereisnospeciedtemperature,usetheunit
withintheoperationaltemperatureboundaryof32to104°F(0to40°C).
● ReadinstallationandappropriateusermanualsforconnectionwithPCorperipheraldevices.Ifa
warningwindowappearsonthePC,theproductstops,doesnotworkproperlyorworksintermittently,
immediatelystopusingtheequipment.
