Precautions When The Compressor Is To Be Idle For An Extended Period Of Time - Hitachi NEXT Series Instruction Manual

10. PRECAUTIONS WHEN THE COMPRESSOR IS TO BE IDLE FOR AN EXTENDED PERIOD OF TIME

① If the compressor is not to be used for a week or
more, be sure to press the UNLOAD STOP button on
the instrument panel.
The compressor then unloads for 5 minutes and auto-
matically stops when the compressor and its piping
are dry.
IMPORTANT
Unloading the compressor prior to stopping enables
moisture in the second stage air end to be removed.
Drying out the inside of the compressor is an effective
way to prevent rust from developing in the second stage
air end when unused for an extended period of time.
② To prevent the inside of the compressor from rusting,
press the UNLOAD STOP button and dry the com-
pressor for 5 - 10 minutes a week.
③ Be sure to turn off the power if the compressor is not
to be used for an extended period of time.
● Failure to take measures to prevent rust could result in rusting due to humidity in the atmosphere or
lack of oil film in the bearings, and could cause the compressor to freeze up or could result in
damage to the bearings when operation is restarted.
● The UNLOAD STOP button is not only used when the compressor is to be idle for an extended period
of time; it is also effective way to prevent the inside of the compressor from rusting during routine
operation as well.
■ Performing unload stop during dual/
backup operation and/or multiple unit
control operation (optional)
If the compressor is to be idle for an extended period
of time, turn off dual/backup operation and/or multiple
unit control operation, press the UNLOAD STOP
button while the compressor is running and dry out
the compressor.
The UNLOAD STOP button is effective when opera-
tion control is set to "SINGLE." For information on
operation control settings, see page 19.)
When restarting operation, return the operation con-
trol to the optional control settings.
