Do not install the air conditioner at a place where combustible gas may leak.
If gas leaks and is collected at surrounding the unit, the production of fire may be caused.
Be sure to attach an earth leakage breaker; otherwise an electric shock may be caused.
Using a torque wrench, tighten the flare nut in the specified method.
If the flare nut is exceedingly tightened, the flare nut is broken and a refrigerant leakage may be caused after a long

ELECTRIC WIRING

Using the exclusive circuit, a person qualified for electrician shall work for the electric work in
conformance with the regulations of the local electric company and the Installation Manual.
If there is capacity shortage of the power circuit or incomplete electric work, a fire or electric shock is caused.
For wiring, use the specified wires and connect them securely so that external force of wire does not
transmit to the terminal connecting section.
If connection or fixing is incomplete, a fire is caused.
Be sure to connect the earth wire.
Grounding work is necessary based upon a law. If the earth grounding is incomplete, an electric shock is caused.
Do not connect earth wire to gas pipe, lightning rod, or earth wire of telephone.
Be sure to attach an earth leakage breaker; otherwise an electric shock may be caused.
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm.
• Perform wiring of the power supply in conformance with the regulations of the local electric company.
• For wiring of power supply in the indoor unit, refer to the Installation Manual of each indoor unit.
• Never connect the 220–240V power to the terminal block (U1, U2, U3, U4, U5, U6) for control wires.
(Trouble is caused.)
• Arrange the wires so that the electric wires do not come to contact with high-temperature part of the pipe;
otherwise coating melts and an accident may be caused.
• After connecting wire to the terminal block, take off the trap and then fix the cable with wire clamp.
• Store wiring system for control and refrigerant piping system in the same line.
• Do not turn on power of the indoor unit until vacuuming of the refrigerant pipe will finish.
• For wiring of the power supply of the indoor unit and the inter-unit cabling between indoor and outdoor units, refer to
the Installation Manual of indoor unit.
Power supply specifications
