• For information about the power cable specifications for indoor and outdoor units, refer to the installation
manual .
• After peeling off cable wires from the pre-installed tube, insert a contraction tube .
• If cable wires are connected without using connecting sleeves, their contact area becomes reduced, or corrosion
develops on the outer surfaces of the wires (copper wires) over a long time . This may cause an increase of
resistance (reduction of passing current) and consequently may result in a fire .
