 Incompleteinstallationcouldcausere,electricshock,injuryduetothe
unit falling, or leakage of water.
nWhen installing the unit, use appropriate protective equipment and
tools for safety.
Failure to do so could cause injury.
nInstall 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 could
fall causing injury.
n Electrical work should be performed by a qualied, 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 insufcient or there is incomplete
electricalwork,itcouldresultinareoranelectricshock.
n Do not damage the wires by applying excessive pressure with parts
or screws.
 Damagedwirescouldcausereorelectricshock.
n Be sure to cut off the main power in case of setting up the indoor P.C.
board or wiring works.
Failure to do so could cause electric shock.
n Use the specied wires to connect the indoor and outdoor units
securely and attach the wires rmly 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re.
n Do not install the unit in a place where inammable gas may leak.
If gas leaks and accumulates in the area around the unit, it could cause an
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.
 Itcouldcauseareoranelectricshockduetodefectivecontact,defective
insulation, exceeding the permissible current, etc.
n Be sure to use the parts provided or specied parts for the installation
work.
The use of defective parts could cause an injury or leakage of water due
toare,anelectricshock,theunitfalling,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.
If there is dust, clogging, or loose parts on the power supply plug or the
outlet,itcouldcauseelectricshockorre.Ifloosepartsarefoundonthe
power supply plug, replace it.
n Attach the electrical cover to the indoor unit and the service panel
to the outdoor unit securely.
If the electrical cover of the indoor unit and/or the service panel of the
outdoorunitarenotattachedsecurely,itcouldresultinareoranelectric
shock due to dust, water, etc.
n When installing, relocating, or servicing the unit, make sure that no
substance other than the specied refrigerant (R410A) enters the
refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pres-
sure rise and may result in explosion or injury. The use of any refrigerant
otherthanthat speciedforthesystemwill causemechanicalfailure,
system malfunction, or unit breakdown. In the worst case, this could lead
to a serious impediment to securing product safety.
n Do not discharge the refrigerant into the atmosphere. If refrigerant
leaks during installation, ventilate the room.
 Ifrefrigerantcomesincontactwithare,harmfulgascouldbegener-
ated. Refrigerant leakage may cause suffocation. Provide ventilation in
accordance with EN378-1.
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ame
of a fan heater, space heater, stove, etc., harmful substances will be
generated.
n Use appropriate tools and piping materials for installation.
The pressure of R410A is 1.6 times more than R22. Not using appropriate
tools or materials and incomplete installation could cause the pipes to
burst or injury.
n When pumping down the refrigerant, stop the compressor before
disconnecting the refrigerant pipes.
If the refrigerant pipes are disconnected while the compressor is running
and the stop valve is open, air could be drawn in and the pressure in the
refrigeration cycle could become abnormally high. This could cause the
pipes to burst or injury.
n When installing the unit, securely connect the refrigerant pipes
before starting the compressor.
If the compressor is started before the refrigerant pipes are connected
and when the stop valve is open, air could be drawn in and the pressure
in the refrigeration cycle could become abnormally high. This could cause
the pipes to burst or injury.
n Fasten a are nut with a torque wrench as specied in this manual.
 Iffastenedtootight,aarenutmaybreakafteralongperiodandcause
refrigerant leakage.
n The unit shall be installed in accordance with national wiring regula-
tions.
nEarth the unit correctly.
Do not connect the earth to a gas pipe, water pipe, lightning rod or tele-
phone earth. Defective earthing could cause electric shock.
nBe sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shock or
re.
nPerform the drainage/piping work securely according to the installation
manual.
If there is defect in the drainage/piping work, water could drop from the unit,
soaking and damaging household goods.
n Do not touch the air inlet or the aluminum ns of the outdoor unit.
This could cause injury.
nDo not install the outdoor unit where small animals may live.
If small animals enter and touch the electric parts inside the unit, it could
causeamalfunction,smokeemission,orre.Also,adviseusertokeep
the area around the unit clean.

•Over-tighteningmaycausedamagetothearenut,resultinginrefrigerantleakage.
•Besuretowrapinsulationaroundthepiping.Directcontactwiththebarepipingmayresultinburnsorfrostbite.
3-3. INSULATION AND TAPING
1) Cover piping joints with pipe cover.
2) For outdoor unit side, surely insulate every piping including valves.
3) Using piping tape (E), apply taping starting from the entry of outdoor unit.
• Stoptheendofpipingtape(E)withtape(withadhesiveagentattached).
• Whenpipinghavetobearrangedthroughaboveceiling,closetorwherethetemperatureandhumidityare
high, wind additional commercially sold insulation to prevent condensation.
1) Remove service port cap of stop valve on the side of the outdoor unit
gas pipe. (The stop valves are fully closed and covered in caps in
their initial state.)
2) Connect gauge manifold valve and vacuum pump to service port of
stop valve on the gas pipe side of the outdoor unit.
3) Run the vacuum pump. (Vacuumize for more than 15 minutes.)
4) Check the vacuum with gauge manifold valve, then close gauge
manifold valve, and stop the vacuum pump.
5) Leave as it is for one or two minutes. Make sure the pointer of gauge
manifoldvalveremainsinthesameposition.Conrmthatpressure
gaugeshows-0.101MPa[Gauge](-760mmHg).
6) Remove gauge manifold valve quickly from service port of stop valve.
7) Fully open all stop valves on the gas pipe and the liquid pipe. Operating
without fully opening lowers the performance and this causes trouble.
8) Refer to 1-2., and charge the prescribed amount of refrigerant if
needed. Be sure to charge slowly with liquid refrigerant. Otherwise,
composition of the refrigerant in the system may be changed and
affect performance of the air conditioner.
9) Tighten cap of service port to obtain the initial status.

4-2. GAS CHARGE
Perform gas charge to unit.
1) Connect gas cylinder to the service port of stop valve.
2) Perform air purge of the pipe (or hose) coming from refrigerant gas cylinder.
3)Replenishspeciedamountoftherefrigerant,whileoperatingtheairconditioner
for cooling.
Note:
Incaseofaddingrefrigerant,complywiththequantityspeciedfortherefrigerat-
ing cycle.
CAUTION:
When charging the refrigerant system with additional refrigerant, be sure to use
liquid refrigerant. Adding gas refrigerant may change the composition of the refriger-
ant in the system and affect normal operation of the air conditioner. Also, charge
the liquid refrigerant slowly, otherwise the compressor will be locked.
To maintain the high pressure of the gas cylinder, warm the gas cylinder with
warmwater(under40°C)duringcoldseason.Butneverusenakedreorsteam.

4-4. LOWERING THE OPERATION NOISE OF THE OUTDOOR UNIT
• Descriptionofthefunction:
 Withthisfunction,oncetheoperationmodeislockedtoeitherCOOL/DRYmode
orHEATmode,theairconditioneroperatesinthatmodeonly.
* Changing the setting is required to activate this function. Please explain about
this function to your customers and ask them whether they want to use it.
[How to lock the operation mode]
1) Be sure to turn off the main power for the air conditioner before making the
setting.
2)Setthe“1”ofSW1ontheoutdoordisplayboardtoONtoenablethisfunction.
3)TolocktheoperationmodeinCOOL/DRYmode,setthe“2”ofSW1onthe
outdoordisplayboardtoOFF.TolocktheoperationinHEATmode,setthe
same switch to ON.
4) Turn on the main power for the air conditioner.
• Descriptionofthefunction:
With this function, the operating noise of the outdoor unit can be lowered by reducing the operation load, for example, during nighttime in COOL mode.
However,pleasenotethatthecoolingandheatingcapacitymaylowerifthisfunctionisactivated.
* Changing the setting is required to activate this function. Please explain about this function to your customers and ask them whether they want to use it.
Lower the operating noise
[How to lower the operating noise]
1) Be sure to turn off the main power for the air conditioner before making the
setting.
2)Setthe“3”ofSW1ontheoutdoordisplayboardtoONtoenablethisfunction.
3) Turn on the main power for the air conditioner.
4-5. TEST RUN
• Testrunsoftheindoorunitsshouldbeperformedindividually.Seetheinstallationmanualcomingwiththeindoorunit,andmakesurealltheunitsoperate
properly.
• Ifthetestrunwithalltheunitsisperformedatonce,possibleerroneousconnectionsoftherefrigerantpipesandtheindoor/outdoorunitconnectingwires
cannot be detected. Thus, be sure to perform the test run one by one.
Make sure that the following is done.
• Powerissuppliedtotheunit.
• Stopvalvesareopen.
About the restart protective mechanism
Once the compressor stops, the restart preventive device operates so the compressor will not operate for 3 minutes to protect the air conditioner.
When relocating or disposing of the air conditioner, pump down the system following the procedure below so that no refrigerant is released into the atmosphere.
1) Turn off the breaker.
2) Connect the gauge manifold valve to the service port of the stop valve on the gas pipe side of the outdoor unit.
3) Fully close the stop valve on the liquid pipe side of the outdoor unit.
4) Turn on the breaker.
5) Start the emergency COOL operation on all the indoor units.
6)Whenthepressuregaugeshows0.05to0MPa[Gauge](approx.0.5to0kgf/cm2), fully close the stop valve on the gas pipe side of the outdoor unit and
stop the operation. (Refer to the indoor unit installation manual about the method for stopping the operation.)
 * Iftoomuchrefrigeranthasbeenaddedtotheairconditionersystem,thepressuremaynotdropto0.05MPa[Gauge](approx.0.5kgf/cm2), or the protec-
tion function may operate due to the pressure increase in the high-pressure refrigerant circuit. If this occurs, use a refrigerant collecting device to collect
all of the refrigerant in the system, and then recharge the system with the correct amount of refrigerant after the indoor and outdoor units have been
relocated.
7) Turn off the breaker. Remove the pressure gauge and the refrigerant piping.
When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.
The compressor may burst and cause injury if any foreign substance, such as air, enters the pipes.
