REQUIREMENT · 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. · Never connect 220­240V power to the terminal blocks ( A , B , etc. ) for control wiring. (Otherwise, the system will fail. ) · 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 wire clamp. · Run the refrigerant piping line and control wiring line in the same line. · Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes. How to wire 1. Connect the connecting wire to the terminal as identified with their respective numbers on the terminal block of indoor and outdoor unit. H07 RN-F or 245 IEC 66 (1. 5 mm2 or more) 2. Insulate the unsheathed redundant cords (conductors) with electrical insulation tape. Process them so that they do not touch any electrical or metal parts.
