I agree with the 3 posts above.
HVAC installs are really not for a DIY, although I have not seen a "Mr Cool" mini here in NJ. A HVACR Licensed Contractor is required for the install as far as the refrigerant is required. In other than a single family, owner occupied residence, a Licensed Electrical Contractor is also required for the electrical install, and yes, a 120volt, GFI receptacle is required within 25 feet (unobstructed) of the CU.
Best left to the pro.
