* The above values apply during energy recovery ventilation when the fan speed is set to Fan speed 4 at the
rating pressure loss and 230 V / 60 Hz.
* For the specifications at the other frequency or voltages, see the spec. sheets.
* The values given in the table for the noise level reflect the levels measured at a position 4.9 feet (1.5 m)
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 average of summer and winter condition.
* Mitsubishi Electric measures products according to Japan Industrial Standard (JIS B 8628:2003), therefore
characteristic values 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 damp-
ers, etc., it is difficult to measure air volume correctly. A straight duct length more than 10 D (D=duct diame-
ter) 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 proce-
dures for buildings AG3/89.3 (2001))
