CAUTION (Couldleadtoseriousinjuryinparticularenvironmentswhenoperatedincorrectly.)
nDo not install the unit by yourself (user).
 Incompleteinstallationcouldcausereorelectricshock,injuryduetotheunit
falling, or leakage of water. Consult the dealer from whom you purchased
theunitoraqualiedinstaller.
nPerform the installation securely referring to the installation manual.
 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 tel-
ephone 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.
