Safety Considerations
• Read these Safety Considerations carefully to ensure
correct installation.
• ThismanualclassiestheprecautionsintoDANGER,
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
incontactwithresuchasfromafanheater,stoveor
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
incontactwithresuchasfromafanheater,stoveor
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.
• Donotinstallunitinanareawhereammablematerials
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,orequipmentdamage.
• Install the air conditioner according to the instructions
given in this manual.

• 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.
Insufcientcapacityorincompleteelectricalworkmay
causeelectricalshock,reorequipmentdamage.
• 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,
reorequipmentdamage.)
• Usethespeciedtypesofwiresforelectricalconnections
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,reorequipmentdamage.
• 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
maycauseterminaloverheating,electricalshock,reor
equipment damage.
• When installing or relocating the system, be sure to keep
the refrigerant circuit free from all substances other than
thespeciedrefrigerant(R410A),suchasair.
(Any presence of air or other foreign substance in the
refrigerant circuit causes an abnormal pressure rise which
mayresultinrupture,resultingininjury.)
• 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
resultinelectricallyshocks,orrepersonalinjury.
CAUTION
• Do not install the air conditioner where gas leakage would be
exposedtoopenames.

• 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.

WARNING
• Donotmixanysubstanceotherthanthespeciedrefrigerant(R410A)intotherefrigerationcycle.
• If refrigerant gas leaks should occur, ventilate the room as soon and as much as possible.
• R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.
• Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum
pump or the unit.
• When piping work is complete, it is necessary to perform a pressure test
and evacuate system with a vacuum pump.
• If using additional refrigerant, perform air purging of the refrigerant pipes
and indoor unit using a vacuum pump, then charge additional refrigerant.

5. Relling refrigerant
Check the type of refrigerant to be used on the machine nameplate.
Precautions when adding R410A
Fill from the liquid pipe in liquid form.
This is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal
operation.
1)Beforelling,checkwhetherthecylinderhasasiphonattachedornot.(Itshouldhavesomethinglike“liquidllingsiphon
attached”displayedonit.)
Filling a cylinder with an attached siphon
Stand the cylinder upright when filling.
There is a siphon pipe inside, so the
cylinder need not be upside-down to
fill with liquid.
Filling other cylinders
Turn the cylinder upside-down
when filling.
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.

Trial Operation and Testing
• Before starting the test run, measure the voltage at the primary side of the circuit breaker.
• Check that all liquid and gas stop valves are fully open.
• Check that piping and wiring all match. The wiring error check can be conveniently used for underground wiring and other wiring
that cannot be directly checked.
1. Wiring error check
This product is capable of automatic correction of wiring error.
PressthewiringerrorcheckswitchontheoutdoorunitservicePC-board.However,the
wiring error check switch will not function for 3 minutes after the safety breaker is turned
on,ordependingontheoutsideairconditions(SeeNote2.).About15-20minutesafter
the switch is pressed, the errors in the connection wiring will be corrected.
The service monitor LEDs indicate whether or not correction is possible, as
shown in the table below. For details about how to read the LED display, refer to
the service manual.
If self-correction is not possible, check the indoor unit wiring and piping in the usual
manner.

• Operate the indoor units in accordance with the included operation manual. Check that they operate normally.
3. Test items
Are the indoor units installed securely?
Has an inspection been made to check for gas leakage?
Has complete thermal insulation been done (gas pipes, liquid
pipes, indoor portions of the drain hose extension)?
Is the drainage secure?
Are the ground wire connections secure?
Are the electric wires connected correctly?
Is the wiring in accordance with the specifications?
Are the inlets/outlets of the indoor and outdoor units free of any obstructions?
Are the stop valves open?
Do the marks match (room A, room B, room C, room D) on the

Considérations sur la sécurité
• Lisez attentivement ces Considérations sur la sécurité
pour assurer une installation correcte.
• Ce manuel classe les précautions de la manière suivante
DANGER, AVERTISSEMENT et ATTENTION.
Assurez-vous de suivre toutes les précautions ci-dessous:
elles sont toutes essentielles pour assurer la sécurité.
DANGER ........... Indique une situation extrêmement
dangereuse qui, si elle n'est pas
évitée, entraînera la mort ou des
blessures graves.
AVERTISSEMENT
... Le non-respect de l'une des
précautions AVERTISSEMENT
est susceptible d'entraîner des
conséquences aussi dramatiques
que la mort ou de graves blessures.
ATTENTION ...... Le non-respect de l'une des
précautions ATTENTION peut, dans
certains cas, entraîner de graves
conséquences.
• Après avoir terminé l'installation, testez l'unité pour
vérierqu'iln'yapasd'erreurdansl'installation.Donnez
à l'utilisateur les instructions adéquates concernant
l'utilisation et le nettoyage de l'unité conformément au
manuel d'utilisation.
DANGER
• Le gaz réfrigérant est plus lourd que l'air et remplace
l'oxygène. Une fuite importante peut conduire à un
appauvrissement en oxygène, en particulier en sous-sol,
et un risque d'asphyxie peut survenir et entraîner des
blessures graves ou la mort.
•
Si vous constatez des fuites de gaz réfrigérant pendant
l'installation, aérez immédiatement la zone.
Le gaz réfrigérant peut produire un gaz toxique s'il entre en
contactavecuneammecommeàpartird'unventilateur
de chauffage, une cuisinière ou un appareil de cuisson.
L'exposition à ce gaz peut provoquer des blessures graves
ou la mort.
•
Aprèsl'achèvementdestravauxd'installation,vériezque
le gaz réfrigérant ne fuit pas.
Le gaz réfrigérant peut produire un gaz toxique s'il entre en
contactavecuneammecommeàpartird'unventilateur
de chauffage, une cuisinière ou un appareil de cuisson.
L'exposition à ce gaz peut provoquer des blessures graves
ou la mort.
• Ne reliez pas les unités à des conduites d'eau, à des
câbles téléphoniques ou à des paratonnerres, car une
mise à la terre incomplète peut provoquer un risque
d'électrocution important pouvant entraîner des blessures
graves ou la mort; ne les reliez pas non plus à des tuyaux
de gaz car une fuite de gaz peut provoquer une explosion
et entraîner des blessures graves ou la mort.
