Note: Unless otherwise noted, the pressure unit MPa represents the gauge pressure in this manual.
 If operation at partial load, which is not greater than 30 % of the indicated load, is
continued for a long time except when starting up the machine, abnormal noises or
vibration may be generated. So avoid such operation.
 Repeated startup and stop in a short period is harmful not for the startup devices
and electric machinery but also for the compressor itself. For information on the
start/stop limitations, refer to each instruction manual. Wait at least 15 minutes
after stopping the compressor before restarting it.
