  • Page 3: Safety Precautions

    1. Safety precautions Read the following precautions thoroughly before the maintenance, and then inspect and repair the product in a safe manner. The types and levels of danger that may arise if the product is handled incorrectly are described with the warning symbols shown below.

  • Page 4: Specifications

    *Temperature exchange efficiency (%) are based on winter condition. * Mitsubishi Electric measures products according to Japan Industrial Standard (JIS B 8628), therefore Q-H curves are meas- ured by chamber method. * On-site commissioning measurements by pitot tube method could be as much 20% different 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 vol- ume correctly.
