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.
• Install the indoor unit at least 8'2" (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
• Suction duct length must be longer than 33.5" (850 mm).
• When the indoor unit is to be suspended, the designated hanging
bolts W3/8" (M10) and nuts W3/8" (M10) 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.

• 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.
• 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.
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.
