    it is otherwise safe to clean the piping - meaning

    WARNING !
    The flushing system may only be used when it is otherwise safe to clean the piping.

    I would like to know if my thinking is right.

    I understand "it is otherwise safe to clean the piping" as follows:

    it is, in other aspects, safe to clean the piping where "it" is a dummy subject (as, for instance, in "it is so easy to do this thing") and does not refer to "the flushing system".

    Thank you.


    The fragment is taken from operating/maintenance instructions for HS-ISO pressure valve.

    That is the way I would read it. If it is safe to clean the piping, the flushing system may be used.

    What about the dummy subject "it"? Is "it" really the dummy subject? I think so. Could you confirm or deny?

    Yes, it is a dummy subject.
