The installation of the cables has to be done in such a way that the basic insulated wires for the infrared sensor can not be touched. Use the power supply cord/cables with thickness, type, and protective devices specified in the installation manual. Prepare the interior power supply cord and cables wiring with current capacity sufficient for starting and usage of air conditioner. CAUTION 1. Wrong wiring connection may cause some electrical parts burn out. Be sure to use the cord clamps and the electric parts cover to the specified positions with attached to the product. Mount the electrical parts cover for cables of connecting section firmly with the screws. Do not damage or scratch the conductive core and inner insulator of power supply and inter connecting cables when peeling them. Be sure to comply with local cords on running the wire from indoor unit to outdoor unit (size of wire and wiring method etc. ) Wire type : More than H05 RN-F 5. Use the power supply cord and inter-connecting cable with specified thickness, specified type, and protective devices specified. No wire should touch refrigerant piping, compressor of any moving parts. Fig. Insert a flare nut into the pipe, and flare the pipe. Outer dia.
