slack.
Electrical wiring
• Only a qualifi ed installer(*1) or qualifi ed service person(*1) is
allowed to carry out the electrical work of the air conditioner.
Under no circumstances must this work be done by an
unqualifi ed individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.
• Pipe-work shall be protected from physical damage.
• Compliance with national gas regulations shall be observed.
Selection of installation location
• If you install the unit in a small room, take appropriate measures
to prevent the refrigerant from exceeding the limit concentration
even if it leaks. Consult the dealer from whom you purchased
the air conditioner when you implement the measures.
Accumulation of highly concentrated refrigerant may cause an
oxygen defi ciency accident.
• Do not install the air conditioner in a location that may be
subject to a risk of expire to a combustible gas. If a combustible
gas leaks and becomes concentrated around the unit, a fi re
may occur.
• When transporting the air conditioner, wear shoes with
additional protective toe caps.
• When transporting the air conditioner, do not take hold of the
bands around the packing carton. You may injure yourself if the
bands should break.
• Do not place any combustion appliance in a place where it is
directly exposed to the wind of air conditioner, otherwise it may
cause imperfect combustion.
• Do not install the air conditioner in a poorly ventilated space that
is smaller than the minimum fl oor area (Amin).
This applies to:
• Indoor units
• Outdoor units installed
(example: winter garden, garage, machinery room, etc)
Refer to “15 Appendix - [2] Minimum floor area: Amin (m
2
)” to
determine the minimum floor area.
Installation
• Install the air conditioner at enough strong places to withstand
the weight of the unit. If the strength is not enough, the unit may
fall down resulting in injury.

until qualifi ed service person arrives. Continuing to use the
air conditioner in the trouble status may cause mechanical
problems to escalate or result in electric shocks, etc.
• After the work has fi nished, be sure to use an insulation tester
set (500 V Megger) to check the resistance is 1 MΩ or more
between the charge section and the non-charge metal section
(Earth section). If the resistance value is low, a disaster such as
a leak or electric shock is caused at user’s side.
• Upon completion of the installation work, check for refrigerant
leaks and check the insulation resistance and water drainage.
Then conduct a test run to check that the air conditioner is
operating properly.
• After the installation work, confi rm that refrigerant gas does
not leak. If refrigerant gas leaks into the room and fl ows near
a fi re source, such as a cooking range, noxious gas may be
generated.
Explanations given to user
• Upon completion of the installation work, tell the user where the
circuit breaker is located. If the user does not know where the
circuit breaker is, he or she will not be able to turn it off in the
event that trouble has occurred in the air conditioner.
• If you have discovered that the fan guard is damaged, do not
approach the outdoor unit but set the circuit breaker to the OFF

to the customer how to use and maintain the unit.
Relocation
• Only a qualifi ed installer(*1) or qualifi ed service person(*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unqualifi ed individual since a
fi re, electric shocks, injury, water leakage, noise and/or vibration
may result.
• When carrying out the pump-down work shut down the
compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left
open and the compressor still operating will cause air, etc. to
• The appliance shall be installed in accordance with national
wiring regulations. Capacity shortages of the power circuit or an
incomplete installation may cause an electric shock or fi re.
• Use wiring that meets the specifi cations in the Installation
Manual and the stipulations in the local regulations and laws.
Use of wiring which does not meet the specifi cations may give
rise to electric shocks, electrical leakage, smoking and/or a fi re.
• Be sure to connect earth wire. (Grounding work)
Incomplete grounding causes an electric shock.
• Do not connect ground wires to gas pipes, water pipes, and
lightning rods or ground wires for telephone wires.
• After completing the repair or relocation work, check that the
ground wires are connected properly.
• Install a circuit breaker that meets the specifi cations in the
installation manual and the stipulations in the local regulations
and laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
• Under no circumstances must the power cable be extended.
Connection trouble in the places where the cable is extended
may give rise to smoking and/or a fi re.
Test run
• Before operating the air conditioner after having completed the
work, check that the electrical parts control box cover of the
indoor unit and service panel of the outdoor unit are closed,
and set the circuit breaker to the ON position. You may receive
an electric shock etc. if the power is turned on without fi rst
conducting these checks.
