Notes
1. indicates wiring on site.
2.Use twin core cord (0.75~1.25mm
line between indoor unit and outdoor unit, and
signal line between indoor units.

3.Use twin core cord (0.3mm ) at remote
controller line. See spec sheet of remote
controller in case that the total length is more
than 100m.
4.Do not put signal line and remote controller line
alongside power source line.
