Appreciate all the help I will measure it and call John and let you know.

I have the resources to get it installed just out of my element on what exactly I need and cant get a straight answer. Just want to purchase the right thing as to not have trouble with it all the time and for it to work correctly. Done a lot of things just never worked with any type of cooler.

No I bought it locally from a closed Farm Fresh Store. I googled walk in cooler forum and yours popped up with someone else asking a question. I am kind of at a last resort. After purchasing the unit I poured a pad and cut a hole in my garage never dreamed purchasing a condensing unit for it would be so much trouble.

I am located in Salem Illinois. I do not have 3ph available where cooler is located. The compressor will sit outside. I will have to get exact dimensions of the inside when I get home tonight before I call him. Thanks for the advice.
