• Use the specified wires for wiring connect the terminals.
Securely fix them to prevent external forces applied to the
terminals from affecting the terminals.
Incomplete connection or fixation may cause a fire or other trouble.
• Connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect earth wires to gas pipes, water pipes, lightning
conductor or telephone earth wires.
• Appliance shall be installed in accordance with national wiring
regulations.
Capacity shortage of power circuit or incomplete installation may
cause an electric shock or a fire.
• If incorrect / incomplete wiring is carried out, it will cause an electrical
fire or smoke.
• Install an earth leakage breaker that is not tripped by shock waves.
If an earth leakage breaker is not installed, an electric shock may be
caused.
• Use the cord clamps attached to the product.
• Do not damage or scratch the conductive core and inner insulator of
power and inter-connecting wires when peeling them.
• Use the power cord and Inter-connecting wire of specified thickness,
type, and protective devices required.
• Do not connect 220 V – 240 V power to the terminal blocks ( , , ,
) for control wiring and the terminal blocks (COM, S1, S2, S3, S4,
S5) for output function. (Otherwise, the system will fail.)
• Do not damage or scratch the conductive core and inner insulator of
power and inter-connecting wires when peeling them.
• Perform the electric wiring so that it does not come to contact with the
high-temperature part of the pipe.
The coating may melt resulting in an accident.

• For power supply wiring, strictly conform to the Local Regulation in each country.
• For wiring of power supply of the outdoor units, follow the Installation Manual of each outdoor unit.
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.The
coating may melt resulting in an accident.
• After connecting wires to the terminal blocks, provide a trap and fix wires with the cord clamp.
• Run the refrigerant piping line and control wiring line in the same line.
• Do not turn on the power of the hot water module until vacuuming of the refrigerant pipes completes.
