  1. The numerical value indicated above is based on 25 ℃ of suction air temperature and 80% of relative humidity. The performance capacity is 90% or more of the indicated.
  2. The numerical value indicated above is based on 25 ℃ of suction air temperature, 80% of relative humidity and 30 ℃ of ambient temperature of an outdoor unit. The performance capacity is 90% or more of the indicated.
  3. In case of use of beyond operable temperature range, it cannot operate with cooler. (It may rise in room temperature due to force dehumidifying operation.)
  4. The figures in parentheses show dimensions before a plenum chamber is attached.
  5. Not including outdoor unit.
  6. The sound level is the value measured 1 meter away from the front and 1 meter high.
    ・ The plenum chamber shall be assembled and installed at the site.
    ・ The electric wiring, wiring of an outdoor unit and refrigeration piping must be arranged at the site.
