gas leak and accumulate around the unit, it may ignite and cause a fire.
• 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.
Installation
• 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 specied 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.

• 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.

Installation Manual
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(*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 finished, use an insulation tester set (500V Megger) to
check the resistance is 1MΩor 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.
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.
• While 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.
