Been thru two chest freezers and now an upright, so here's the stuff I wish someone had told me before my first purchase. First, check the actual space where it's going. Measure width, depth, AND the door swing, plus leave a couple inches behind for the coils to breathe. Then when you get it home, let it stand upright for several hours before plugging in if it was tilted during transport. Oil in the compressor needs to settle. Plug it in empty and give it a full day to pull down to temp before you load a single bag of anything. Second, test the door seal yourself before the return window closes. Close the door on a dollar bill and pull. If it slides out with no resistance at several spots around the gasket, that's your cue to exchange it early rather than fight with a warm freezer full of meat in six months. On the electrical side, a dedicated normal outlet is ideal. These units draw a surge when the compressor kicks on and some older GFCIs don't love that. If yours trips repeatedly on a GFCI circuit, that's ussually the outlet being oversensitive, not the freezer being bad. Also level the thing properly with a bubble level. An unlevel freezer can make the door sag and the seal never quite close evenly, wich looks exactly like a defective gasket.
A quick guide to buying a big upright freezer without the usual headaches

I went through the whole process last winter with a Hisense unit from Costco and found the leveling much trickier than anticipated. I initially used a small carpenter's level and it took a couple of tries to get the feet just right. Mine was sitting on a concrete slab, so the feet sank a bit unevenly untill I adjusted the locking nuts on the corners. It definitely made a difference when I started pushing the door; it wasn't binding like I had heard it might. I also had to be extra careful about the electrical setup. While a dedicated circuit is what everyone suggests, my house had an existing 20-amp line nearby, so after checking the amperage draw on the label, I was okay running a heavy duty extension cord to a properly wired outlet. It was a bit of a hack but got the job done without blowing any breakers. I waited a full twenty-four hours after plugging it in, just doing nothing, before putting the first box of frozen poultry inside. That seems to be the only way to make sure the compressor has settled completely before any load is applied.
Gotta push back on the extension cord bit. Freezer makers are pretty explicit that these things need to go straight into a wall outlet, no cord in between. A long cord running to another room adds resistance and heat, and combined with the startup surge the compressor pulls every time it kicks on, that's how cords melt and houses burn. If the only outlet nearby can't handle it, the right move is having an electrician put in a proper outlet where the freezer sits. Cheap compared to what the alternative costs if it goes wrong.
The leveling thing is real. Mine lives in the garage and the slab had a slight slope to it that I didn't even notice at first. I leveled it the best I coud but kept getting a frost buildup along one side of the lid, which turned out to be the seal not seating evenly on the low end. Stuck a couple of composite shims under the front feet, rechecked with a level both directions, and the frost line evened out within a week. So if anyone's chasing a gasket problem, check your floor before blaming the freezer.
