steam cleaner & GFCI protection

[shade23]

I am installing power to an older 230 volt 30 amp portable electric steam cleaning machine. Is GFCI protection manditory, I can't find anything on this topic.
I want safety first but I also have a customer to think of.

What does the manufacturer's instructions for the steam cleaner say?
