I am working on a pepsi vending machine that has a grounded compressor. I have an R22 skid that was ordered wrong and non returnable. I am going to verify but I think they they are both same horse power compressor. the original is r134a. Would I have an issue if I installed the new condensing unit skid intended for 22 and charged with 134 a. I think it should work fine but just wanted to see if anybody had some major concerns.
