CAUTION (Couldleadtoseriousinjuryinparticularenvironmentswhenoperatedincorrectly.)

n Do not install the unit by yourself (user). Incompleteinstallationcouldcausefireorelectricshock,injuryduetotheunit

falling,orleakageofwater.Consultthedealerfromwhomyoupurchasedtheunitoraqualifiedinstaller.

n Perform the installation securely referring to the installation manual. Incomplete installationcouldcausefire,electricshock, injuryduetothe

unitfalling,orleakageofwater.n When installing the unit, use appropriate protective equipment and

tools for safety. Failuretodosocouldcauseinjury.n Install the unit securely in a place which can bear the weight of the

unit. Iftheinstallationlocationcannotbeartheweightoftheunit,theunitcould

fallcausinginjury.n Electrical work should be performed by a qualified, experienced electri-

cian, according to the installation manual. Be sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit.

If the capacity of thepower circuit is insufficient or there is incompleteelectricalwork,itcouldresultinafireoranelectricshock.

n Do not damage the wires by applying excessive pressure with parts or screws.

Damagedwirescouldcausefireorelectricshock.n Be sure to cut off the main power in case of setting up the indoor P.C.

board or wiring works. Failuretodosocouldcauseelectricshock.n Use the specified wires to connect the indoor and outdoor units

securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Do not extend the wires, or use intermediate connection.

Incompleteconnectingandsecuringcouldcausefire.n Do not install the unit in a place where inflammable gas may leak. Ifgasleaksandaccumulatesintheareaaroundtheunit,itcouldcausean

explosion.n Do not use intermediate connection of the power cord or the extension

cord and do not connect many devices to one AC outlet. Itcouldcauseafireoranelectricshockduetodefectivecontact,defective

insulation,exceedingthepermissiblecurrent,etc.n Be sure to use the parts provided or specified parts for the installation

work. Theuseofdefectivepartscouldcauseaninjuryorleakageofwaterdue

toafire,anelectricshock,theunitfalling,etc.n When plugging the power supply plug into the outlet, make sure that

there is no dust, clogging, or loose parts in both the outlet and the plug. Make sure that the power supply plug is pushed completely into the outlet.

Ifthereisdust,clogging,orloosepartsonthepowersupplyplugortheoutlet,itcouldcauseelectricshockorfire.Ifloosepartsarefoundonthepowersupplyplug,replaceit.

n Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.

Iftheelectricalcoveroftheindoorunitand/ortheservicepaneloftheoutdoorunitarenotattachedsecurely,itcouldresultinafireoranelectricshockduetodust,water,etc.

n When installing, relocating, or servicing the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.

Anypresenceofforeignsubstancesuchasaircancauseabnormalpres-sureriseandmayresultinexplosionorinjury.Theuseofanyrefrigerantother than thatspecified for thesystemwillcausemechanical failure,systemmalfunction,orunitbreakdown.Intheworstcase,thiscouldleadtoaseriousimpedimenttosecuringproductsafety.

n Do not discharge the refrigerant into the atmosphere. If refrigerant leaks during installation, ventilate the room.

Ifrefrigerantcomesincontactwithafire,harmfulgascouldbegener-ated.Refrigerant leakagemaycausesuffocation.ProvideventilationinaccordancewithEN378-1.

n Check that the refrigerant gas does not leak after installation has been completed.

Ifrefrigerantgasleaksindoors,andcomesintocontactwiththeflameofafanheater,spaceheater,stove,etc.,harmfulsubstanceswillbegenerated.

n Use appropriate tools and piping materials for installation. ThepressureofR410Ais1.6timesmorethanR22.Notusingappropriate

toolsormaterialsandincompleteinstallationcouldcausethepipestoburstorinjury.

n When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.

Iftherefrigerantpipesaredisconnectedwhilethecompressorisrunningandthestopvalveisopen,aircouldbedrawninandthepressureintherefrigerationcyclecouldbecomeabnormallyhigh.Thiscouldcausethepipestoburstorinjury.

n Perform the drainage/piping work securely according to the installation manual.

Ifthereisdefectinthedrainage/pipingwork,watercoulddropfromtheunit,soakinganddamaginghouseholdgoods.

n Do not touch the air inlet or the aluminum fins of the outdoor unit. Thiscouldcauseinjury.

n Do not install the outdoor unit where small animals may live. Ifsmallanimalsenterandtouchtheelectricpartsinsidetheunit,itcould
