Notes
- (Note 1) Cooling and heating performance, and electrical characteristics are based on JIS B 8616:2015 temperature conditions and standard piping (piping equivalent length 7.5m (5m for P40~P63 models), 0m head difference). Values in < > indicate the capacity range.
- (Note 2) Power voltage should not exceed ±10% fluctuation.
- (Note 3) When using four indoor units, the values shown are per indoor unit.
- (Note 4) Remote control switches are sold separately. Refer to the 'Remote Controller Outline Drawing' for remote control wiring length.
- (Note 5) The Annual Performance Factor (APF) according to the "Judgment Standards for Manufacturers, etc. for Improving Air Conditioner Performance" (commonly known as the Energy Saving Law Standards) notified by the Ministry of Economy, Trade and Industry, Notification No. 213, is based on "APF (JIS B 8616:2006)".
- (Note 6) Standard airflow is for 'Rapid' setting.
- (Note 7) External static pressure must be adjusted on-site if changed.
- (Note 8) Rated noise (sound power level) is based on JIS B 8616:2015.
- (Note 9) Operating noise (sound pressure level) is based on JIS B 8616:2006.
- (Note 10) If the ground fault interrupter is for ground fault protection only, install a local disconnect switch with a fuse, or a circuit breaker. Use a harmonic-compatible ground fault interrupter.
- (Note 11) Some optional parts may alter the external dimensions, appearance, weight, operating noise, or performance characteristics of the air conditioner.
