Notes
- Cooling and heating performance and electrical characteristics are based on temperature conditions and standard piping (piping equivalent length 7.5m (5m for P40~P63 models), 0m head) according to JIS B 8616:2015. Values in < > indicate the capacity range.
- Power supply voltage should not fluctuate by more than ±10%.
- When using four indoor units, the values shown are per indoor unit.
- Remote control switches are optional accessories. Refer to the 'Remote Control Outline Drawing' for remote control wiring length.
- The Annual Performance Factor (APF) used for the "Judgment Standards for Energy Saving for Air Conditioner Performance" (commonly known as the Energy Saving Law Standards) by the Ministry of Economy, Trade and Industry Public Notice No. 213 is based on "APF (JIS B 8616:2006)".
- Rated airflow is for "High+" setting.
- External static pressure must be adjusted on-site if changed.
- Air filters are not included as standard. Prepare filters on-site or use optional filter chambers, antibacterial high-performance filters, etc.
- Rated sound power level is based on JIS B 8616:2015.
- Sound pressure level is based on JIS B 8616:2006.
- If the leakage breaker is for ground fault protection only, install a main switch + fuse or a circuit breaker. Use a harmonic-aware leakage breaker.
- Depending on optional accessories, the external dimensions, appearance, mass, sound level, and performance characteristics of the air conditioner may change.
