• 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 truck to carry in the air conditioner units and use winch
or hoist at installation of them.
• Helmet must be worn to protect your head from falling objects.
Especially, when you work under an inspection opening, helmet
must be worn to protect your head from falling objects from the
opening.
• The unit can be accessed from the service panel shown in the figure.
• After the unit has been suspended and installed, take dust-proof
measures for the air intake and air discharge openings (cover
these openings) to ensure that no dust will enter inside the unit at
any point until the construction work has been completed.
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 an 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 tightly and in a proper
manner.
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, 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.
• Be sure to connect earth wire. (Grounding work)
Incomplete earthing 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.
