  1. The compressor is cooled by oil injection.
  2. Compressor net weight includes oil charge, but oil is not charged at time of shipment and it should be charged by the unit assembler.
  3. The gas flow rate have been converted into values at atomospheric pressure(32=0)
    The flow rate is based on the condition shown in following table.
  4. Frequency range: 30-78Hz
  5. Power Supply
    A: 200V/50Hz, 200-230V/60Hz
    D: 380-415V/50Hz, 440-480V/60Hz
    H: 208-230V/60Hz
