• When the air conditioner is installed in a small room, provide appropriate measures to ensure
that the concentration of refrigerant leakage occur in the room does not exceed the critical
level.
• Install the air conditioner securely in a location where the base can sustain the weight adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• 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.
• 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
might generate.
• Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix. To prevent external
forces applied to the terminals from affecting the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.

ACCESSORY AND REFRIGERANT
Accessory and Installation Parts Refrigerant Piping
• Piping kit used for the conventional refrigerant cannot be
used.
• Use copper pipe with 0.8 mm or more thickness for Ø9.5.
Use copper pipe with 1.0 mm or more thickness for
Ø15.9.
• Flare nut and flare works are also different from those of
the conventional refrigerant. Take out the flare nut
attached to the main unit of the air conditioner, and use it.
