I sold one at my old house. 3 guys, one two wheeler, about 10 minutes. It was heavy, but not a huge deal.
"Are there any particular precautions"
Yeah, empty it!!!!!!!!!!!!!!!!!!!!
Ok, bad joke. Seriously though, be forewarned, when you stand it one it's side, whatever water is left in the system will pour out (it's a gravity thing). It's not a lot of water, but I'd have towels handy.
