that is properly installed & grounded in accordance with all local codes &

Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or service person if you are in
doubt as to whether the outlet is properly grounded. Do not modify the plug
provided with the machine. If plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Replace the plug if the grounding pin is damaged or broken.
