Attention
1. The above values are at factory default.
2. The running current, the input power, the efficiency and the noise are based on the rating air volume, and 230 V
50 Hz.
3. The sound pressure level at 3 m is spherical.
4. Temperature exchange efficiency (%) is based on winter conditions.
5. Mitsubishi Electric measures figures in the chart according to EN13141-7:2010, and the characteristic curves are
measured by chamber method.
