Is there anything I need to do after the unit is installed?

The concept behind the VPhase device is that it's a fit and forget solution.

Once installed, there's nothing else you need to do... no change in lifestyle... no need to notify your electricity provider...

...just start saving instantly!

There's not much else we can say about this - other than commenting on the warranty period for the VPhase, so that's what the video is focused on.
