■Attention
1. The running current, the input power, the efficiency and the noise are based on the rating air volume, and
230V/50Hz. The noise is measured at 1.5m under the center of the unit in an anechoic chamber.
2. Temperature exchange efficiency (%) is based on winter condition.
3. Heat recovery ventilation mode starts automatically while detecting OA temperature lower than 8℃, even Bypass
mode is selected. Remote controller continues to display "Bypass ventilation" in this case.
4. Mitsubishi Electric measures figures in the chart according to Japan Industrial Standard (JIS B 8628), therefore the
characteristic curves are measured by chamber method.
5. The noise level at 1.5m away from outlets in the 45°direction is about 21dB greater than the indicated value at
fanspeed4.
6. On-site measurements by pitot tube method could be as much 20% difference from JIS test room conditions. If the
measuring point is close to sources of turbulence like bends, contractions and dampers etc., it is difficult to measure
air volume correctly. A straight duct length more than 10D (D=duct diameter) from the source of turbulence is
recommended for correct measurement. On-site measurement should therefore be measured in accordance with
BSRIA guideline (Commissioning Air Systems. Application procedures for buildings AG3/89.3(2001)).
7. Use this unit between static pressure 60Pa and 240Pa at Fan speed4. Otherwise the motor protection may work
and reduce its output or the noise level might be larger.
