See Fig.2 for combinations for outdoor and indoor units. For the GJ series air conditioning system, one
outdoor unit is able to drive up to five indoor units which can be cassette type, duct type, high wall or floor
console type. The outdoor unit will run as long as any one indoor unit receives the running command, and all
indoor units stop once the outdoor unit is turned off.
