Safety Considerations
• Read these Safety Considerations carefully to ensure
correct installation.
• ThismanualclassiestheprecautionsintoDANGER,
WARNING and CAUTION.
Be sure to follow all the precautions below: they are all
important for ensuring safety.
DANGER ........... Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING ......... Failure to follow any of WARNING
is likely to result in such grave
consequences as death or serious
injury.
CAUTION .......... Failure to follow any of CAUTION
may in some cases result in grave
consequences.
• After completing installation, test the unit to check for
installation errors. Give the user adequate instructions
concerning the use and cleaning of the unit according to the
Operation Manual.
DANGER
• Refrigerant gas is heavier than air and replaces oxygen.
A massive leak could lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death.
• If the refrigerant gas leaks during installation, ventilate the
area immediately.
Refrigerant gas may produce a toxic gas if it comes
incontactwithresuchasfromafanheater,stoveor
cooking device.
Exposure to this gas could cause severe injury or death.
• After completing the installation work, check that the
refrigerant gas does not leak.
Refrigerant gas may produce a toxic gas if it comes
incontactwithresuchasfromafanheater,stoveor
cooking device.
Exposure to this gas could cause severe injury or death.
• Do not ground units to water pipes, telephone wires or
lightning rods because incomplete grounding could cause
a severe shock hazard resulting in severe injury or death,
and to gas pipes because a gas leak could result in an
explosion which could lead to severe injury or death.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that
children will not play with them.
Children playing with plastic bags face the danger of death
by suffocation.
• Donotinstallunitinanareawhereammablematerials
are present due to risk of explosion resulting in serious
injury or death.
• Do not ground units to telephone wires or lightning rods
because lightning strikes could cause a severe shock
hazard resulting in severe injury or death, and to gas
pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

WARNING
• Installation shall be left to the authorized dealer or another
trained professional.
Improper installation may cause water leakage, electrical
shock,re,orequipmentdamage.
• Install the air conditioner according to the instructions
given in this manual.
Incomplete installation may cause water leakage,
electricalshock,reorequipmentdamage.
•
Besuretousethesuppliedorexactspeciedinstallationparts.
Use of other parts may cause the unit to come to fall,
waterleakage,electricalshock,reorequipmentdamage.
• Install the air conditioner on a solid base that is level and
can support the weight of the unit.
An inadequate base or incomplete installation may cause
injury or equipment damage in the event the unit falls off
the base or comes loose.
• Electrical work shall be carried out in accordance with
the installation manual and the national, state and local
electrical wiring codes.
Insufcientcapacityorincompleteelectricalworkmay
causeelectricalshock,reorequipmentdamage.
• Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance.
Follow all appropriate electrical codes.
• For wiring, use a wire or cable long enough to cover the
entire distance with no splices if possible.
Do not use an extension cord. Do not put other loads on
the power supply.
Use only a separate dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock,
reorequipmentdamage.)
• Usethespeciedtypesofwiresforelectricalconnections
between the indoor and outdoor units.
Follow all state and local electrical codes.
Firmly clamp the inter-unit wire so their terminals receive
no external stresses.
Incomplete connections or clamping may cause terminal
overheating,reorequipmentdamage.
• After connecting all wires be sure to shape the cables so
that they do not put undue stress on the electrical covers,
panels or terminals.
Install covers over the wires. Incomplete cover installation
maycauseterminaloverheating,electricalshock,reor
equipment damage.
• When installing or relocating the system, be sure to keep
the refrigerant circuit free from all substances other than
thespeciedrefrigerant(R410A),suchasair.
(Any presence of air or other foreign substance in the
refrigerant circuit causes an abnormal pressure rise which
may result in rupture, resulting in injury.)
• During pump down, stop the compressor before removing
the refrigerant piping.
If the compressor is still running and the stop valve is
open during pump down, air will be sucked in when the
refrigerant piping is removed, causing abnormally high
pressure which could lead to equipment damage or and
personal injury.
• During installation, attach the refrigerant piping securely
before running the compressor.
If the refrigerant pipes are not attached and the stop valve
is open during installation, air will be sucked in when the
compressor is run, causing abnormally high pressure
which could lead to equipment damage and personal injury.
• Be sure to install a ground fault circuit interrupter.
Failure to install a ground fault circuit interrupter may
resultinelectricallyshocks,orrepersonalinjury.
CAUTION
• Do not install the air conditioner where gas leakage would be
exposedtoopenames.
Ifthegasleaksandbuildsuparoundtheunit,itmaycatchre.
• Establish drain piping according to the instructions of this
manual.
Inadequate piping may cause water damage.
• Tightenthearenutaccordingtothespeciedtorque.A
torque wrench should be used.
Ifthearenutistightenedtoomuch,thearenutmaycrack
over time and cause refrigerant leakage.
• Donottouchtheheatexchangerns.
Improper handling may result in injury.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any
PP bands for a means of transportation. It is dangerous.
• Make sure to provide for adequate measures in order to
prevent that the outdoor unit be used as a shelter by small
animals.
Small animals making contact with electrical parts can cause
malfunctions,smokeorre.Pleaseinstructthecustomerto
keep the area around the unit clean.
• The temperature of refrigerant circuit will be high, please
keep the inter-unit wire away from copper pipes that are not
thermally insulated.
• Electrical work must be performed in accordance with the
NEC/CEC by authorized personnel only.

Precautions for Selecting the Location
1) Chooseaplacesolidenoughtobeartheweightandvibrationoftheunit,wheretheoperatingsoundwillnotbeamplied.
2) Choose a location where the hot air discharged from the unit or the operating sound will not cause a nuisance to the
neighbours of the user.
3) Avoid places near a bedroom and the like, so that the operating sound will cause no trouble.
4) Theremustbesufcientspacesforcarryingtheunitintoandoutofthesite.
5) Theremustbesufcientspaceforairpassageandnoobstructionsaroundtheairinletandtheairoutlet.
6) Thesitemustbefreefromthepossibilityofammablegasleakageinanearbyplace.
7) Installunits,powercordsandinter-unitwireatleast10ft(3m)awayfromtelevisionandradiosets.(Thisistoprevent
interferencetoimagesandsounds.Noisemaybeexperiencedeveniftheyaremorethan10ft(3m)awaydependingonradio
wave conditions.)
8) In coastal areas or other places with a salty atmosphere or one containing sulphate gas, corrosion may shorten the life of the
air conditioner.

2. Drain work
(only for heat pump models)
• Ifthedrainportiscoveredbyamountingbaseoroor
surface, place additional foot bases of at least 1-1/4
inch(30mm)inheightundertheoutdoorunit’sfeet.
• In cold areas, do not use a drain socket, drain
caps (1,2) and a drain hose with the outdoor unit.
(Otherwise, the drain water may freeze, impairing
heating performance.)
1) Attach Cdrain cap (1) and Ddrain cap (2).
2) Attach Bdrain socket.
3. Flaring the pipe end
1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing
downward so that the chips do not enter the pipe.
3) Putthearenutonthepipe.
4) Flare the pipe.
5) Checkthatthearingisproperlymade.
Check
Flare’s inner
surface must
be flaw-free.
The pipe end must
be evenly flared in
a perfect circle.
Make sure that the
flare nut is fitted.
Set exactly at the position shown below. Flaring

WARNING
• Donotusemineraloilonaredpart.
• Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
• Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.
• NeverinstalladriertothisR410Aunitinordertoguaranteeitslifetime.
• The drying material may dissolve and damage the system.
• Incompletearingmaycauserefrigerantgasleakage.
4. Refrigerant piping
CAUTION
• Usethearenutxedtothemainunit.(Thisistopreventcrackingofthearenutasaresultofdeteriorationovertime.)
• Topreventgasleakage,applyrefrigerationoilonlytotheinnersurfaceoftheare.(UserefrigerationoilforR410A.)
• Useatorquewrenchwhentighteningthearenutstopreventdamagetothearenutsandgasleakage.
• Alignthecentersofbotharesandtightenthearenuts3or4turnsbyhand.Thentightenthemfullywithaspanneranda
torque wrench.
