stainless commercial frdige build

a buddy of mine is giving me a double door stainless fridge. havent seen it yet but he stated it takes 3 guys to move it and it was still heavy. i wanted to get some ideas of what kind of heat to use. i would like to just get it up and running quick this year since rifle season is around the corner and we have a bunch of customers lined up for our specialty meats.

all the help would be great. i hope to get the fridge this weekend everyone was out of town for bear season this weekend

thanks in advance guys
