• Use shielded wires for transmission wires between the indoor and the outdoor units and connect the shielded
part to the ground screw in the electrical box of the indoor unit as shown below.
• Use wires not lighter than the ordinary neoprene (polychloroprene) sheathed flexible cord (code designation
H05RN-F).
