Base
Base
of indoor unit (recommended for downflow unit) , outdoor unit
support
or concrete base (determined based on scenarios)
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.
