Notes: For actual capacity performance based on indoor unit type and number of indoor units connected, please refer to MXZ Operational Performance. The maximum connectable capacity can exceed rated capacity, but the outdoor unit cannot provide more than 100% of its rated capacity. This over-capacity capability is useful for load shedding or applications where not all connected units operate simultaneously.
