Note : Unless otherwise noted, the pressure unit MPa represents the gauge pressure in this manual.
 If operation at a indicated load of less than 30 % of capacity control is continued
for a long time except when starting up the machine, abnormal noises or
vibration may occur, so avoid doing so.
 Repeating startup or shutdown operations in a short period of time is detrimental
for the starter and the motor as well as for the compressor itself. Refer to the
documentation of each device for the starting and stopping limitations of the
starter and the motor. After stopping the compressor, wait 15 minutes or more
before performing the next startup procedure.
