2. More comfort
Powerful heating
Advanced heat-pump technology improves heating capacity at low outdoor temperatures. The promotional comparison shows up to 33% higher heating output than the previous 6 HP-class model under the illustrated low-temperature condition.
Low-noise design
The optimised outdoor-unit fan and airflow structure reduce sound levels. The 6 HP J-II promotional rating is shown at 53 dB(A), compared with 56 dB(A) for the previous model. A selectable low-noise mode can reduce rated sound levels by approximately 5 to 8 dB, depending on the operating condition.
