○ ： Wires that are minimum required to operate the ionizer.
△ ： Wires that are required to use the functions.
－ ： Wires that are not necessary with the pulse DC mode. These wires should not be short-circuited with other cables.
7. Air piping
・When the piping is only connected to one port, the other unused port should be plugged with the M-5P
that is packaged together with the ionizer.
