Takethefollowingprecautionstoreducetheriskofpropertydamage.
● Becarefulthatmoisture,dust,orvariantrefrigerantcompoundsnotenter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coalesce.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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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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condensatepipe.Ifyoudo,youmay
havedrainwater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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.
● 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.
