5-EN 6-EN
Installation
• When the indoor unit is to be suspended, the designated hanging bolts (M10 or W3/8) and nuts (M10 or W3/8) must be
used.
• Install the air conditioner securely in a location where the base can sustain the weight adequately. If the strength is not
enough, the unit may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow these instructions may
cause the product to fall down or topple over or give rise to noise, vibration, water leakage or other trouble.
• Carry out the specifi ed installation work to guard against the possibility of high winds and earthquake. If the air
conditioner is not installed appropriately, a unit may topple over or fall down, causing an accident.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas
comes in contact with fi re, noxious gas may generate.
• Use forklift to carry in the air conditioner units and use winch or hoist at installation of them.
Refrigerant piping
• Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the compressor is
operated with the valve open and without refrigerant pipe, the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
• Tighten the fl are nut with a torque wrench in the specifi ed manner. Excessive tighten of the fl are nut may cause a crack
in the fl are nut after a long period, which may result in refrigerant leakage.
• 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.
• When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the
air completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not 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.
• To connect the electrical wires, repair the electrical parts or undertake other electrical jobs, wear gloves to provide
protection for electricians, insulating shoes and clothing to provide protection from electric shocks. Failure to wear this
protective gear may result in electric shocks.
• 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.
• Connect earth wire. (Grounding work)
• Incomplete grounding causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning conductor or telephone earth wires.
• After completing the repair or relocation work, check that the earth 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 the power wire must not be extended. Connection trouble in the places where the wire is
extended may give rise to smoking and/or a fi re.
• Electrical wiring work shall be conducted according to law and regulation in the community and installation manual.
Failure to do so may result in electrocution or short circuit.
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 the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF position, and contact
a qualifi ed 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 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 or
other gas to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly
resulting in rupture, injury or other trouble.
CAUTION
New refrigerant air conditioner installation
• This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also
been changed. Therefore, do not let water, dust, former refrigerant, or refrigerating oil enter the refrigerating cycle during
installation work.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the
main unit and installation tools are changed from those for the conventional refrigerant.
• Accordingly the exclusive tools are required for the new refrigerant (R410A).
• For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not
enter.
To disconnect the appliance from 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 types can be used) must be used for the power supply line of this conditioner.
(*1) Refer to the “Defi nition of Qualifi ed Installer or Qualifi ed Service Person.”
Test run
• Before operating the air conditioner after having completed the work, check that the electrical 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 if the power is turned on without fi rst conducting these checks.
• If there is any kind of trouble (such as an error display has appeared, smell of burning, abnormal sounds, 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 qualifi ed service person (*1). Take steps to ensure
that the power will not be turned on (by marking “out of service” near the circuit breaker, for instance) until qualifi ed
service person (*1) arrives. Continuing to use the air conditioner in the trouble status may cause mechanical problems to
escalate or result in electric shocks or other trouble.
• After the work has fi nished, 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
7-EN 8-EN
drainage. Then conduct a test run to check that the air conditioner is operating properly.
