usetoolsandpipecomponentsspecicallymadeforusewithR410Arefrig-

erant.TheR410ArefrigerantintheHFCsystemispressurized1.6timesthe

pressureofusualrefrigerants.IfpipecomponentsnotdesignedforR410A

refrigerantareusedandtheunitisnotinstalledcorrectly,thepipesmayburst

andcausedamageorinjuries.Inaddition,waterleakage,electricshock,or

remayresult.

• Theunitmustbeinstalledaccordingtotheinstructionsinordertominimize

theriskofdamagefromearthquakes,typhoons,orstrongwinds.Anincor-

rectlyinstalledunitmayfalldownandcausedamageorinjuries.

• Theunitmustbesecurelyinstalledonastructurethatcansustainitsweight.

Iftheunitismountedonanunstablestructure,itmayfalldownandcause

damage

orinjuries.

• Iftheairconditionerisinstalledinasmallroom,measuresmustbetakento

preventtherefrigerantconcentrationintheroomfromexceedingthesafety

limitintheeventofrefrigerantleakage.Consultadealerregardingtheappro-

priatemeasurestopreventtheallowableconcentrationfrombeingexceeded.

Shouldtherefrigerantleakandcausetheconcentrationlimittobeexceeded,

hazardsduetolackofoxygenintheroommayresult.

• Ventilatetheroomifrefrigerantleaksduringoperation.Ifrefrigerantcomes

intocontactwithaame,poisonousgaseswillbereleased.

• Allelectricworkmustbeperformedbyaqualiedtechnicianaccordingto

localregulationsandtheinstructionsgiveninthismanual.Theunitsmustbe

poweredbydedicatedpowerlinesandthecorrectvoltageandcircuitbreakers

mustbeused.Powerlineswithinsufcientcapacityorincorrectelectrical

workmayresultinelectricshockorre.

• UseC1220copperphosphorus,forcopperandcopperalloyseamlesspipes,

toconnecttherefrigerantpipes.Ifthepipesarenotconnectedcorrectly,the

unitwillnotbeproperlygroundedandelectricshockmayresult.

• Useonlyspeciedcablesforwiring.Thewiringconnectionsmustbemade

securelywith notension appliedontheterminalconnections. Also,never

splicethecablesforwiring(unlessotherwiseindicatedinthisdocument).

 Failuretoobservetheseinstructionsmayresultinoverheatingorare.

• Theterminalblockcoverpaneloftheoutdoorunitmustbermlyattached.If

thecoverpanelismountedincorrectlyanddustandmoistureentertheunit,

electricshockorremayresult.

• Theapplianceshallbeinstalledinaccordancewithnationalwiringregulations.

• Ifthesupplycordisdamaged,itmustbereplacedbythemanufacturer,its

serviceagentorsimilarlyqualiedpersonsinordertoavoidahazard.

• Wheninstallingorrelocating,orservicingtheairconditioner,useonlythe

speciedrefrigerant(R410A)tochargetherefrigerantlines.Donotmixitwith

anyotherrefrigerantanddonotallowairtoremaininthelines.

 Ifairismixedwiththerefrigerant,thenitcanbethecauseofabnormalhigh

pressure in the refrigerant line, and may result in an explosion and other

hazards.

 Theuseofanyrefrigerantotherthanthatspeciedforthesystemwillcause

mechanical failure or systemmalfunctionor

 unit breakdown.Intheworst

case,thiscouldleadtoaseriousimpedimenttosecuringproductsafety.

• UseonlyaccessoriesauthorizedbyMitsubishiElectricandaskadealeroran

authorizedtechniciantoinstallthem.Ifaccessoriesareincorrectlyinstalled,

waterleakage,electricshock,orremayresult.

• Donotaltertheunit.Consultadealerforrepairs.Ifalterationsorrepairsare

notperformedcorrectly,waterleakage,electricshock,orremayresult.

• Theusershouldneverattempttorepairtheunitortransferittoanotherloca-

tion.Iftheunitisinstalledincorrectly,waterleakage,electricshock,orre

mayresult.Iftheairconditionermustberepairedormoved,askadealeror

anauthorizedtechnician.

• Afterinstallationhasbeencompleted,checkforrefrigerantleaks.Ifrefriger-

antleaksintotheroomandcomesintocontactwiththeameofaheateror
