CAUTION!

This mark indicates procedures which, if improperly performed,

might possibly result in personal harm to the user, or damage to

property.

Read carefully all security information before use or install the air conditioner.

Do not attempt to install the air conditioner or a part of the air conditioner by yourself.

This unit must be installed by qualified personnel with a capacity certificate for handling

refrigerant fluids. Refer to regulation and laws in use on installation place.

e installation must be carried out in compliance with regulations in force

in the place

of installation and the installation instructions of the manufacturer.

This unit is part of a set constituting an air conditioner. It must not be installed alone or

with non-authorized by the manufacturer.

Always use a separate power supply line protected by a circuit breaker operating on all

wires with a distance between contact of 3mm for this unit.

The unit must be correctly grounded and the supply line must be equipped with a

differential breaker in order to protect the persons.

The units are not explosion proof and therefore should not be installed in explosive

atmosphere.

Never touch electrical components immediately after the power supply has been turned

off. Electric shock may occur. After turning off the power, always wait 5 minutes before

touching electrical components.

This unit contains no user-serviceable parts. Always consult authorized service

personnel to repairs.

When moving, consult authorized service personnel for disconnection and installation of

the unit.

2. ABOUT THE UNIT

2.1. Precautions for using the R410A refrigerant

WARNING

• Do notintroduceanysubstance other than the prescribed refrigerant into the

refrigeration cycle.

If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become

abnormally high and cause the piping to rupture.

• Ifthereisarefrigerantleakage,makesurethatitdoesnotexceedtheconcentration

limit.

If a refrigerant leakage exceeds the concentration limit, it can lead to accidents such

as oxygen starvation.

• Do nottouch refrigerant thathas leaked fromthe refrigerant pipe connections or

other area. Touching the refrigerant directly can cause frostbite.

• If a refrigerant leakage occurs during operation, immediately vacate the premises

and thoroughly ventilate the area.

 Iftherefrigerantcomesincontactwithaame,itproducesatoxicgas.

2.2. Special tool for R410A

WARNING

• To install a unit that uses the R410Arefrigerant, use dedicated toolsand piping

materialsthathavebeenmanufacturedspecicallyforR410Ause.

 BecausethepressureoftheR410Arefrigerantisapproximately1.6timeshigherthan

the R22, failure to use dedicated piping material or improper installation can cause

rupture or injury.

Furthermore, it can cause serious accidents such as water leakage, electric shock, or

re.

Tool name Contents of change

Gauge manifold

•Pressureishugeandcannotbemeasuredwithaconventional

gauge. To prevent erroneous mixing of other refrigerants, the

diameter of each port has been changed.

It is recommended to use a gauge manifold with a high

pressuredisplayrange–0.1to5.3MPaandalowpressure

displayrange–0.1to3.8MPa.

Charging hose

•Toincreasepressureresistance,thehosematerialandbase

1. SAFETY PRECAUTIONS

• BesuretoreadthisManualthoroughlybeforeinstallation.

• ThewarningsandprecautionsindicatedinthisManualcontainimportantinformation

pertaining to your safety. Be sure to observe them.

• HandthisManual,togetherwiththeOperatingManualtothecustomer.

Request the customer to keep them on hand for future use, such as for relocating or

repairing the unit.

WARNING!

This mark indicates procedures which, if improperly performed,

might lead to the death or serious injury of the user.

• Requestyourdealeroraprofessionalinstallertoinstalltheunitinaccordancewith

thisManual.

An improperly installed unit can cause serious accidents such as water leakage,

electricshock,orre.

 IftheunitisinstalledindisregardoftheinstructionsintheInstallationManual,itwill

void the manufacturer’s warranty.

• DonotturnONthepoweruntilallworkhasbeencompleted.

 Turning ON the power before thework is completed can cause serious accidents

suchaselectricshockorre.

• Ifrefrigerantleakswhileworkisbeingcarriedout,ventilatethearea.

Iftherefrigerantcomesincontactwithaame,itproducesatoxicgas.

• Installationworkmustbeperformedinaccordancewithnationalwiringstandardsby

authorized personnel only.

• ExceptforEMERGENCY, neverturn offmainas wellassub breakerof theindoor

units during operation. It will cause compressor failure as well as water leakage.

First, stop the indoor unit by operating the control unit, converter or external input

device and then cut the breaker.

 Makesuretooperatethroughthecontrolunit,converterorexternalinputdevice.

When the breaker is designed, locate it at a place where the users cannot start and

stop in the daily work.

3. INSTALLATION WORK

3.1. Selecting an installation location

Especially, the installation place is very important for the split type air conditioner

becauseitisverydifculttomovefromplacetoplaceaftertherstinstallation.

WARNING

• Selectinstallationlocationsthatcanproperlysupporttheweightoftheindoor.Install

the units securely so that they do not topple or fall.

CAUTION

• Donotinstalltheunitinthefollowingareas:

• Areawithhighsaltcontent,suchasattheseaside.

It will deteriorate metal parts, causing the parts to fail or the unit to leak water.

• Arealledwithmineraloilorcontainingalargeamountofsplashedoilorsteam,

such as a kitchen.

It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.

• Area that generates substances that adversely affect the equipment, such as

sulfuric gas, chlorine gas, acid, or alkali.

It will cause the copper pipes and brazed joints to corrode, which can cause

refrigerant leakage.

• Areathatcancausecombustiblegastoleak,containssuspendedcarbonbersor

ammabledust,orvolatileinammablessuchaspaintthinnerorgasoline.

PIPE INSTALLATION

CAUTION

• Be careful that foreign matter (oil, water, etc.) does not enter the piping with

refrigerantR410Amodels.Also,whenstoringthepiping,securelysealtheopenings

by pinching, taping, etc.

• While brazing the pipes, be sure to purge with dry nitrogen gas.

4.1. Selecting the pipe material

CAUTION

• Do not use existing pipes.

• Use pipes that have clean external and internal sides without any contamination

which may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or

water.

• It is necessary to use seamless copper pipes.

Material:Phosphordeoxidizedseamlesscopperpipes

Itisdesirablethattheamountofresidualoilislessthan40mg/10m.

• Do not use copper pipes that have a collapsed, deformed, or discolored portion

(especiallyontheinteriorsurface).Otherwise,theexpansionvalveorcapillarytube

may become blocked with contaminants.

• Improperpipeselectionwilldegradeperformance.AsanairconditionerusingR410A

incurs pressure higher than when using conventional refrigerant, it is necessary to

choose adequate materials.

•

ThicknessesofcopperpipesusedwithR410Aareasshowninthetable.

•

Never use copper pipes thinner than those indicated in the table even if they are

available on the market.

• Usepipewithwater-resistantheatinsulation.

CAUTION

• Install heat insulation around both the gas and liquid pipes. Failure to do so may

cause water leaks.

Useheatinsulationwithheatresistanceabove120°C.(Reversecyclemodelonly)

In addition, if the humidity level at the installation location of the refrigerant piping is

expectedtoexceed70%,installheatinsulationaroundtherefrigerantpiping.Ifthe

4.3.2. Bending pipes

•

If pipes are shaped by hand, be careful not to collapse them.

•

Donotbendthepipesinananglemorethan90°.

•

When pipes are repeatedly bend or stretched, the material will harden, making it

difculttobendorstretchthemanymore.

•

Do not bend or stretch the pipes more than 3 times.

CAUTION

• To prevent breaking of the pipe, avoid sharp bends.

• If the pipe is bent repeatedly at the same place, it will break.

4.3.3. Pipe connection

CAUTION

• Be sure to install the pipe against the port on the indoor unit correctly. If the centering

isimproper,thearenutcannottightensmoothly.Ifthearenutisforcedtoturn,the
