• This system consists of multiple indoor units. Mark each indoor unit as unit A, unit B..., and be sure
the terminal board wiring to the outdoor unit and BS unit are properly matched. If wiring and piping
between the outdoor unit and an indoor unit are mismatched, the system may cause a malfunction.
• A circuit breaker capable of shutting down power supply to the entire system must be installed.
• Refer to the installation manual attached to the outdoor unit for the size of power supply wiring
connected to the outdoor unit, the capacity of the circuit breaker and switch, and wiring instructions.
