） at signal line between indoor unit
and outdoor unit, and signal line between indoor units.
3. Use twin core cord（0.3mm
2
） at remote control line.
See spec sheet of remote control in case that the total length is more than 100m. 4. Do not put signal line and remote control line alongside power source line.
5. Circuit option in （※1） is not include
