Electrical wiring
• Only a qualified installer(*1) or qualified 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 unqualified individual since failure to carry out
the work properly may result in electric shocks and/or electrical leaks.
• 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 fire.
• Use wiring that meets the specifications in the Installation Manual and the stipulations in the local regulations and
laws. Use of wiring which does not meet the specifications may give rise to electric shocks, electrical leakage,
smoking and/or a fire.
• 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 specifications 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 fire.
Test run
• Before operating the air conditioner after having completed the work, check that the electrical parts 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 first conducting these checks.
• When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of
burning, abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the
air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact
a qualified service person. Take steps to ensure that the power will not be turned on (by marking "out of service"
near the circuit breaker, for instance) until qualified 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 finished, be sure to use an insulation tester set (500V 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, confirm that refrigerant gas does not leak. If refrigerant gas leaks into the room and flows
near a fire 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 position, and contact a qualified service person(*1) to have the repairs done. Do not set the circuit breaker
to the ON position until the repairs are completed.
• After the installation work, follow the Owner's Manual to explain to the customer how to use and maintain the unit.
Relocation
• Only a qualified installer(*1) or qualified service person(*1) is allowed to relocate the air conditioner. It is dangerous
for the air conditioner to be relocated by an unqualified individual since a fire, 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 be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly
resulting in reputing, injury, etc.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY
OZONE LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working
pressure of R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the
new refrigerant, the refrigeration machine oil has also been changed. Therefore, during installation work, be sure that
water, dust, former refrigerant, or refrigeration machine oil does not enter the new type refrigerant R410A air
conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main
unit and installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are
required for the new refrigerant (R410A) units. For connecting pipes, use new and clean piping materials with high
pressure fittings made for R410A only, so that water and/or dust does not enter.
To Disconnect the Appliance from the Main Power Supply
• This appliance must be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm.
• The installation fuse (all fuse types can be used) must be used for the power supply line of this conditioner.
Do not wash air conditioners with pressure washers.
• Electric leaks may cause electric shocks or fires.
