1. BEFORE INSTALLATION1-1. THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY• Besuretoread“THEFOLLOWINGSHOULDALWAYSBEOBSERVEDFORSAFETY”beforeinstallingtheairconditioner.• Be sure to observe the warnings and cautions specified here as they include important items related to safety• Afterreadingthismanual,besuretokeepittogetherwiththeOPERATINGINSTRUCTIONSforfuturereference.• EquipmentcomplyingwithIEC/EN6�000-3-�2.

1-2. SPECIFICATIONS

CAUTION (Couldleadtoseriousinjuryinparticularenvironmentswhenoperatedincorrectly.)

n Do not install the unit by yourself (user). Incomplete installation could cause fire or electric shock, injury due to the

unitfalling,or leakageofwater.Consultthedealerfromwhomyoupur-chased the unit or a qualified installer

n Perform the installation securely referring to the installation manual. Incomplete installation could cause fire, electric shock, injury due to the

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. If the installation location cannot bear the weight of the unit, the unit

couldfallcausinginjury.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 the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock

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

Damaged wires could cause fire or electric shockn 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 se-

curely 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.

Incomplete connecting and securing could cause firen Do not install the unit in a place where inflammable gas may leak Ifgas leaksandaccumulates intheareaaroundtheunit, itcouldcause

anexplosion.n Do not use intermediate connection of the power cord or the exten-

sion cord and do not connect many devices to one AC outlet. It could cause a fire or an electric shock due to defective contact, defec-

tiveinsulation,exceedingthepermissiblecurrent,etc.n Be sure to use the parts provided or specified parts for the installa-

tion work. Theuseofdefectivepartscouldcauseaninjuryorleakageofwaterdue

to a fire, an electric shock, the unit falling, etcn 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 complete-ly into the outlet.

Ifthere isdust,clogging,or loosepartsonthepowersupplyplugortheoutlet, it could cause electric shock or fire. If loose parts are found on the powersupplyplug,replaceit.

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

Iftheelectricalcoverofthe indoorunitand/ortheservicepaneloftheoutdoor unit are not attached securely, it could result in a fire or an electricshockduetodust,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.

Any presence of foreign substance such as air can cause abnormalpressureriseandmayresult inexplosionor injury.Theuseofanyre-frigerant other than that specified for the system will cause mechanical failure,systemmalfunction,orunitbreakdown. In theworstcase, thiscouldleadtoaseriousimpedimenttosecuringproductsafety.

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

If refrigerant comes in contact with a fire, harmful gas could be generated.Refrigerantleakagemaycausesuffocation.Provideventilationinaccord-ancewithEN378-�.

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

If refrigerant gas leaks indoors, and comes into contact with the flameofa fanheater,spaceheater,stove,etc.,harmfulsubstanceswillbegenerated.

n Use appropriate tools and piping materials for installation. ThepressureofR4�0Ais�.6timesmorethanR22.Notusingappropri-

atetoolsormaterialsandincompleteinstallationcouldcausethepipestoburstorinjury.

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

If the refrigerantpipesaredisconnectedwhile thecompressor is run-ningandthestopvalveisopen,aircouldbedrawninandthepressurein the refrigeration cycle could become abnormally high. This couldcausethepipestoburstorinjury.

n When installing the unit, securely connect the refrigerant pipes before starting the compressor.

Ifthecompressorisstartedbeforetherefrigerantpipesareconnectedandwhen thestopvalve isopen,aircouldbedrawn inand thepres-sure in the refrigerationcyclecouldbecomeabnormallyhigh.Thiscouldcausethepipestoburstorinjury.

n Fasten a flare nut with a torque wrench as specified in this manual. If fastened too tight, a flare nut may break after a long period and cause

refrigerantleakage.n The unit shall be installed in accordance with national wiring regu-

lations. n Earth the unit correctly. Donotconnecttheearthtoagaspipe,waterpipe,lightningrodortel-

ephoneearth.Defectiveearthingcouldcauseelectricshock.

n Install an earth leakage breaker depending on the installation place. Ifanearthleakagebreakerisnotinstalled,itcouldcauseelectricshock.n Perform the drainage/piping work securely according to the installa-

tion manual. If there isdefect in thedrainage/pipingwork,watercoulddrop from the

unit,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. Ifsmall animals enterand touch the electricparts inside the unit, it

could cause a malfunction, smoke emission, or fire. Also, advise user tokeeptheareaaroundtheunitclean.

WARNING (Couldleadtodeath,seriousinjury,etc.)

*� Connect to the power switch which has a gap of 3 mm or more whenopentointerruptthesourcepowerphase.(Whenthepowerswitchisshutoff,itmustinterruptallphases.)

*2 Use wires in conformity with design 60245 IEC 57. Use the indoor/out-door connecting wire in conformity with the wire specifications specified in theinstallationmanualoftheindoorunit.
