• The refrigerant inside the unit is fl ammable. If the refrigerant
leaks in the room and comes in contact with fi re from a burner,
a heater, or a cooker, it may result in fi re or the formation of a
harmful gas.
• Turn off any combustible heating devices, ventilate the room,
and contact the dealer from which you purchased the unit.
• Do not use the unit until a service person confi rms that the
portion from which the refrigerant leaked is repaired.
• When installing, relocating, or servicing the air conditioner, use
only the specifi ed refrigerant (R32) to charge the refrigerant
lines. Do not mix it with any other refrigerant and do not allow
air to remain in the lines.
• Pipe-work shall be protected from physical damage.
• Compliance with national gas regulations shall be observed.
Selection of installation location
• If you install the unit in a small room, take appropriate measures
to prevent the refrigerant from exceeding the limit concentration
even if it leaks. Consult the dealer from whom you purchased
the air conditioner when you implement the measures.
Accumulation of highly concentrated refrigerant may cause an
oxygen defi ciency accident.
• Do not install the air conditioner in a location that may be
subject to a risk of expire to a combustible gas. If a combustible
gas leaks and becomes concentrated around the unit, a fi re
may occur.
• When transporting the air conditioner, wear shoes with
additional protective toe caps.
• When transporting the air conditioner, do not take hold of the
bands around the packing carton. You may injure yourself if the
bands should break.
• 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.
• Do not install the air conditioner in a poorly ventilated space that
is smaller than the minimum fl oor area (A
This applies to:
• Indoor units

• Outdoor units installed
(example: winter garden, garage, machinery room, etc)
Refer to "15 Appendix - [2] Minimum fl oor area: A
determine the minimum fl oor area.
Installation
• Install the air conditioner at enough strong places to withstand
the weight of the unit. 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, etc.
• The designated bolts (M10) and nuts (M10) for securing the
outdoor unit must be used when installing the unit.
• Install the outdoor unit property in a location that is durable
enough to support the weight of the outdoor unit.
• Insuffi cient durability may cause the outdoor unit to fall, which
may result in injury.
• 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 be generated.
• The installation of pipe work shall be kept to a minimum.
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 fl are nut with a torque wrench in the specifi 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.
• For installation and relocation work, follow the instructions in
the Installation Manual and use tools and pipe components
specifi cally made for use with R32 refrigerant. If pipe
components not designed for R32 refrigerant are used and the
unit is not installed correctly, the pipes may burst and cause
damage or injuries. In addition, water leakage, electric shock, or
fi re may result.
