Unless otherwise noted, the pressure unit MPa represents the gauge pressure in this manual.
For limits of working temperature and pressure, see Section 2.3.2 "Operation Limits" in this
Chapter.
*Note: The design pressure varies according to each area, laws and ordinances of the country.
The design pressure of this list is the maximum value of the compressor. Therefore, the
real design pressure may become less than this value according to the law.
Please confirm real pressure on a name plate and individual specifications.
