• 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 floor area: A
determine the minimum floor 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 an 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.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not
slack.
Electrical wiring
• Only a qualifi ed installer(*1) or qualifi ed 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
unqualifi ed individual since failure to carry out the work properly
may result in electric shocks and/or electrical leaks.
