there are a couple of things that you should be sure of 1. can your panel handle a 220v unit proper load calculations only allow 80amp in an 100 panel. 2. remember that 110v hurts and can kill you, 220v will fuck your shit up(i've been hit with both) 3. if you can turn the main off do it reseting all your clocks is better than death 4. if you not comfortable doing it don't, its not that much money to have someone do it.
