Specify the inspection methods/intervals of the compressor protection devices, and make sure to
provide users of this product with such information.
In the operation test, check that alarms and protective devices operate normally by
using devices such as pressure tester. Do not operate the compressor with all the
valves closed, or in any other dangerous conditions.
If the protection from low oil pressure (OP), high pressure (HP) activates, do not
restart operation until the cause of activation is removed.
