• 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.
• 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 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 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.
Installation
• 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.
• Carry out the specied 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 fire, noxious
gas may generate.
• Use forklift to carry in the air conditioner units and use winch or hoist at
installation of them.
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.
