cable is required.
When the NetCol8000-A045/A055/A060 indoor unit is used,
prepare one group of outdoor unit cables for each indoor unit. (If
two indoor units are used, prepare two groups of outdoor unit
cables.) When the NetCol8000-A090/120 indoor unit is used,
prepare two groups of outdoor unit cables for each indoor unit.
