1. Safetyprecautions

1.3. Beforeelectricwork

Caution:

• Besuretoinstallcircuitbreakers.Ifnotinstalled,electricshockmayresult.

• Forthepowerlines,usestandardcablesofsufcientcapacity.Otherwise,a

shortcircuit,overheating,orremayresult.

• Wheninstalling the powerlines,do notapplytension tothecables. Ifthe

connectionsareloosened,thecablescansnaporbreakandoverheatingor

remayresult.

1.4. Beforestartingthetestrun

Caution:

• Turnonthemainpowerswitchmorethan12hoursbeforestartingoperation.

Startingoperationjustafterturningonthepowerswitchcanseverelydamage

theinternalparts.Keepthemainpowerswitchturnedonduringtheoperation

season.

• Beforestartingoperation,checkthatallpanels,guardsandotherprotective

partsarecorrectlyinstalled.Rotating,hot,orhighvoltagepartscancause

injuries.

• Donottouchanyswitchwithwethands.Electricshockmayresult.

• Besuretogroundtheunit.Donotconnectthegroundwiretogasorwater

pipes,lightningrods,ortelephonegroundinglines.Iftheunitisnotproperly

grounded,electricshockmayresult.

• Usecircuitbreakers(groundfaultinterrupter,isolatingswitch(+Bfuse),and

moldedcasecircuitbreaker)withthespeciedcapacity.Ifthecircuitbreaker

capacityislargerthanthespeciedcapacity,breakdownorremayresult.

• Do not touch the refrigerant pipes with bare hands during operation. The

refrigerantpipesarehotorcolddependingontheconditionoftheowing

refrigerant.Ifyoutouchthepipes,burnsorfrostbitemayresult.

• Afterstoppingoperation,besuretowaitatleastveminutesbeforeturning

offthemainpowerswitch.Otherwise,waterleakageorbreakdownmayresult.

1.5. UsingR410Arefrigerantairconditioners

Caution:

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

toconnecttherefrigerantpipes.Makesuretheinsidesofthepipesareclean

anddonotcontainanyharmfulcontaminantssuchassulfuriccompounds,

oxidants,debris,ordust.Usepipeswiththespeciedthickness.(Referto

4.1.)NotethefollowingifreusingexistingpipesthatcarriedR22refrigerant.

- Replacetheexistingarenutsandarethearedsectionsagain.

- Do not use thin pipes. (Refer to 4.1.)

• Storethepipestobeusedduringinstallationindoorsandkeepbothendsof

thepipessealeduntiljustbeforebrazing.(Leaveelbowjoints,etc.intheir

packaging.)Ifdust,debris,ormoistureenterstherefrigerantlines,oildete-

riorationorcompressorbreakdownmayresult.

• Useesteroil,etheroil,alkylbenzeneoil(smallamount)astherefrigeration

oilappliedtothearedsections.Ifmineraloilismixedintherefrigeration

oil,oildeteriorationmayresult.

• DonotuserefrigerantotherthanR410Arefrigerant.Ifanotherrefrigerantis

used,thechlorinewillcausetheoiltodeteriorate.

• UsethefollowingtoolsspecicallydesignedforusewithR410Arefrigerant.

The following tools are necessary to use R410Arefrigerant. Contact your

nearestdealerforanyquestions.

Tools (for R410A)

Gauge manifold Flare tool

Charge hose Size adjustment gauge

Gas leak detector Vacuum pump adapter

Torque wrench Electronic refrigerant charging scale

• Besuretousethecorrecttools.Ifdust,debris,ormoistureenterstherefriger-

antlines,refrigerationoildeteriorationmayresult.

• Donotuseachargingcylinder.Ifachargingcylinderisused,thecomposition

oftherefrigerantwillchangeandtheefciencywillbelowered.

1.2. Beforeinstallation(relocation)

Caution:

• Beextremelycarefulwhentransportingtheunits.Twoormorepersonsare

neededtohandletheunit,asitweighs20kgormore.Donotgraspthepack-

agingbands.Wearprotectiveglovestoremovetheunitfromthepackaging

andtomoveit,asyoucaninjureyourhandsonthensorotherparts.

• Besuretosafelydisposeofthepackagingmaterials.Packagingmaterials,such

asnailsandothermetalorwoodenpartsmaycausestabsorotherinjuries.

• Thebaseandattachmentsoftheoutdoorunitmustbeperiodicallychecked

forlooseness,cracksorotherdamage.Ifsuchdefectsareleftuncorrected,

theunitmayfalldownandcausedamageorinjuries.

• Donotcleantheairconditionerunitwithwater.Electricshockmayresult.

• Tightenallarenutstospecicationusingatorquewrench.Iftightenedtoo

much,thearenutcanbreakafteranextendedperiodandrefrigerantcan

leakout.

1.1. Beforeinstallation

Caution:

• Donotusetheunitinanunusualenvironment.Iftheairconditionerisinstalled

inareasexposedtosteam,volatileoil(includingmachineoil),orsulfuricgas,

areasexposedtohighsaltcontentsuchastheseaside,orareaswherethe

unitwillbecoveredbysnow,theperformancecanbesignicantlyreduced

andtheinternalpartscanbedamaged.

• Donotinstalltheunitwherecombustiblegasesmayleak,beproduced,ow,

oraccumulate.Ifcombustiblegasaccumulatesaroundtheunit,reorexplo-

sionmayresult.

• Theoutdoorunitproducescondensationduringtheheatingoperation.Make

suretoprovidedrainagearoundtheoutdoorunitifsuchcondensationislikely

tocausedamage.

• Wheninstallingtheunitinahospitalorcommunicationsofce,bepreparedfor

noiseandelectronicinterference.Inverters,homeappliances,high-frequency

medicalequipment,andradiocommunicationsequipmentcancausetheair

conditionertomalfunctionorbreakdown.Theairconditionermayalsoaffect

medicalequipment,disturbingmedicalcare,andcommunicationsequipment,

harmingthescreendisplayquality.
