* The above values apply during Lossnay ventilation when the fan speed is set to Fan speed 4 at the rating pressure loss and 230 V / 50 Hz.
* For the specifications at the other frequency or voltages, contact your dealer.
* The values given in the table for the noise level reflect the levels measured at a position 1.5 meters immediately below the unit in an anechoic chamber.
* Noise change or increase may occur because of the Bypass-Automatic function or Automatic fan speed change by timer setting and/or other
functions.
* Temperature Exchange efficiency (%) are based on winter condition.
* Mitsubishi Electric measures products according to Japan Industrial Standard (JIS B 8628), therefore P-Q curves are measured by chamber method.
* On-site commissioning 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 or equivalent) from the source of turbulence is recommended for correct measurement. On-site
measurement should therefore be measured in accordance with BSRIA guideline (Commissioning Air System. Application procedures for
buildings AG3/89.3(2001))
