Precautions for safety

The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
WARNING
General
• Before starting to install the air conditioner, read through the Installation Manual carefully, and follow its instructions
to install the air conditioner.
• Only a qualified installer or service person is allowed to do installation work. Inappropriate installation may result in
water leakage, electric shock or fire.
• Do not use any refrigerant different from the one specified for complement or replacement. Otherwise, abnormally
high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or
an injury to your body.
• Before opening the intake grille of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the
OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts. Only a qualified installer (*1) or qualified service person (*1) is allowed to remove the intake grille
of the indoor unit or service panel of the outdoor unit and do the work required.
• Before carrying out the installation, maintenance, repair or removal work, set the circuit breaker to the OFF position.
Otherwise, electric shocks may result.
• Place a "Work in progress" sign near the circuit breaker while the installation, maintenance, repair or removal work
is being carried out. There is a danger of electric shocks if the circuit breaker is set to ON by mistake.
• Only a qualified installer (*1) or qualified service person (*1) is allowed to undertake work at heights using a stand of
50 cm or more or to remove the intake grille of the indoor unit to undertake work.
• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Do not touch the aluminium fin of the unit. You may injure yourself if you do so. If the fin must be touched for some
reason, first put on protective gloves and safety work clothing, and then proceed.
• Do not climb onto or place objects on top of the outdoor unit. You may fall or the objects may fall off of the outdoor
unit and result in injury.
• When work is performed at heights, use a ladder which complies with the ISO 14122 standard, and follow the
procedure in the ladder's instructions. Also wear a helmet for use in industry as protective gear to undertake the work.
• Before cleaning the filter or other parts of the outdoor unit, set the circuit breaker to OFF without fail, and place a
"Work in progress" sign near the circuit breaker before proceeding with the work.
• Before working at heights, put a sign in place so that no-one will approach the work location, before proceeding with
the work. Parts and other objects may fall from above, possibly injuring a person below. While carrying out the work,
wear a helmet for protection from falling objects.
• The refrigerant used by this air conditioner is the R410A.
• The air conditioner must be transported in stable condition. If any part of the product is broken, contact the dealer.
• When the air conditioner must be transported by hand, carry it by two or more people.
• Do not move or repair any unit by yourself. There is high voltage inside the unit. You may get electric shock when
removing the cover and main unit.
Selection of installation location
• When the air conditioner is installed in a small room, provide appropriate measures to ensure that the concentration
of refrigerant leakage occur in the room does not exceed the critical level.
• Do not install in a location where flammable gas leaks are possible. If the gas leak and accumulate around the unit,
it may ignite and cause a fire.
• To transport the air conditioner, wear shoes with additional protective toe caps.
• To transport the air conditioner, do not take hold of the bands around the packing carton. You may injure yourself if
the bands should break.
• Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure themselves or receive
electric shocks if they poke their fingers or other objects into the indoor unit while the air conditioner is running.
• 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.
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 specified 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 fire, 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 flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a
crack in the flare nut after a long period, which may result in refrigerant leakage.
• 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.
• 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 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.
• To connect the electrical wires, repair the electrical parts or undertake other electrical jobs, wear gloves to provide
protection for electricians and from heat, 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 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.
• 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 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.
• To install 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 fire.
• 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.
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 first 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 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 or other trouble.
• After the work has finished, 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.
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 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.
