
DonotturnOFFthemainpowersourceoftheindoorunitduringtheseasonofheatingandcooling.
Thewatercannotbedischargedforcedlysothatoverowsfromthedrainpan.
Astheresult,theoorandtheceilingsurfacearesmudged.


Holdtheairlterandtheairinletgrillebyhandwhenattaching(removing).
Ifnot,itmaycausefallingorinjury.
● Donotblowcoldairtoapersonforalongtimeorovercool.
Itmaycausedeteriorationofphysicalconditionandhealthimpairment.
● Donothandletheunitbyoneperson.Althoughtheunitmaybepackedbypolypropyleneband,donot
useitfortransportation.Iftheunitishandledbyhand,thensurfaceofheatexchangercausesacut.
● Donotinstalltheindoorunit,outdoorunit,wiredcontrollerandcablewithinapproximately3metersfrom
strongelectromagneticwaveradiatorssuchasmedicalequipments.
● Supplyelectricalpowertothesystemtoenergizetheoilheaterfor12hoursbeforestartupafteralong
shutdown.
● Makesurethattheoutdoorunitisnotcoveredwithsnoworice,beforeoperation.
● Insomecases,thepackagedairconditionermaynotbeoperatednormallyunderthefollowingcases.
* Incasethatelectricalpowerforthepackagedairconditionerissuppliedfromthesamepower
 transformerasthedevice*.
*Incasethatthepowersourcewiresforthedevice*andthepackagedairconditionerarelocatedcloseto
 eachother.
Device*: (Ex) Lift,containercrane,rectierforelectricrailway,inverterpowerdevice,arcfurnace,
 electricfurnace,large-sizedinductionmotorandlarge-sizedswitch.
Itconsumesalargequantityofelectricalpower.
 Regardingthecasesmentionedabove,surgevoltagemaybeinductedinthepowersupplywiringforthe
packagedairconditionerduetoarapidchangeinpowerconsumptionofthedeviceandanactivationof
switch.
Therefore,checktheeldregulationsandstandardsbeforeperformingelectricalworkinordertoprotect
thepowersupplyforthepackagedairconditioner.
● Donotinstalltheunitintheplacewheretheairowdirectlycatchestoanimalsorplants.
Itcouldbethecauseofadversea󰀨ecttoanimalsorplants.
● Donotcreateanupper-slopeorriseforthedrainpipingsincedrainwatercanowbacktotheindoorunit
andleakageintotheroomwilloccur.
● Donotapplyexcessiveforcetothearenutwhentightening.Ifitisapplied,thearenutmaycrackdue
toageddegradationandrefrigerantleakagemayoccur.Usethespeciedtighteningtorque.
● Itisrecommendedthattheroomwillbeventilatedevery3to4hours.
● Theheatingcapacityoftheheatpumpunitisdecreasedaccordingtotheoutdoorairtemperature.
Therefore,itisrecommendedthatauxiliaryheatingequipmentbeusedintheeldwhentheunitsis
installedinalowtemperatureregion.
