* 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) immedi-
ately 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 ISO 16494:2014, therefore characteristic values are mea-
sured by chamber method.
* On-site commissioning measurements by pitot tube method could be as much 20% different from ISO 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 10 D (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 System. Application procedures for buildings AG3/89.3
(2001)).
