• 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 speci
fi
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 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.
• 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
fl
are nut with a torque wrench in the speci
fi
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.
• 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.
• This appliance is intended to be used by expert or trained users
in shops, in light industry, or for commercial use by lay persons.
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
fl
ammable gas leaks are
possible. If the gas leak and accumulate around the unit, it may
ignite and cause a
fi
re.
• To transport the air conditioner, wear shoes with additional
protective toecap.
• 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
fl
oor level since
otherwise the users may injure themselves or receive electric
shocks if they poke their
fi
ngers 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 850 mm.
• 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.
