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.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not
slack.

• Do not connect ground wires to gas pipes, water pipes, and
lightning rods or ground wires for telephone wires.
• After completing the repair or relocation work, check that the
ground wires are connected properly.
• Install a circuit breaker that meets the specifi cations in the
Installation Manual and the stipulations in the local regulations
and laws.
