• Do not power other equipment such as vacuum pump from the
outdoor unit. Doing so may cause a fire or a malfunction of the air
conditioner.

so may cause fire, electric shock, injury or water leaks.
• This appliance is intended to be used by expert or trained users
in shops, in light industry, or for commercial use by lay persons.
• We do not take any responsibility on the local design.
Selection of installation location
• Due to the use of the mildly flammable refrigerant R32, there are
safety and legal installation conditions for installing equipment
such as indoor units, Outdoor units, and Shut-off Valve units.
Install each unit according to the section "Installation conditions
for each equipment".
• Do not install in a location where flammable gas may leaks are
possible. If the gas should leak and accumulate around the unit,
it may ignite and cause a fire.
• When transporting the air conditioner, wear shoes with protective
toe caps, protective gloves and other protective clothing.
• When transporting the air conditioner, do not take hold of the
bands around the packing carton. You may injure yourself if the
bands break.
• Install the indoor unit at least 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

unit may cause a disturbance. (Especially at the boundary line
with a neighbor, install the air conditioner while considering the
noise)
Installation
• 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 failure.
• 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. Insufficient
durability may cause the outdoor unit to fall, which may result in
injury.
• Install the unit in the prescribed manner for protection against
strong wind and earthquake. Incorrect installation may result in
the unit falling down, or other accidents.
• Be sure to fix the screws back which have been removed for
installation or other purposes.
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.
