had my j-480 installed 2 weeks ago by Jacuzzi Ontario. They gave me the starter kit and went through the whole operation and chemical maintenance routine. i was a bit wary as this was my first hot tub, but after the instruction from the installer, and the direction sheet they left me it is pretty easy, i had the tub wired by 12:00, filled by 12:30, and my better half was sitting in it at 7:00 pm.... Because i am new i test every day, and like Jim said, i toss in chlorine after each use (Every day) and have shocked it twice, took a water sample into my dealer for testing and was told i am spot on...not too difficult really...
