Dear John:
Okay, that makes more sense. If you plug your grounding probe into an outlet that isn’t properly grounded, your aquarium will still be unprotected and there will still be a risk of electric shocks or worse should there be a catastrophic heater failure or some such accident. So the instructions are merely warning you to have an electrician make sure that the outlet you will be using is properly grounded, if you are unsure whether or not it is.
As I mentioned, this can normally be easily determined simply by examining the outlet: if it can accept 3-way plugs, then the outlet is positively grounded and you can use it for your grounding probe with no concerns. In that event, by all means go ahead and install the grounding probe yourself. It will only take about 60 seconds.
Good luck and good thinking to obtain a grounding probe for your aquarium and to make sure that you are connecting it safely and properly, sir!
