So I am going to try to make this as succinct as possible. A couple of years ago we bought a split unit heat pump model PH13NA036(G)-B. It has never been hooked up. Frankly we are missing either a part or vital knowledge and was hoping one of you can help. Essentially, the unit is hooked up except for the smaller discharge line. We are unable to find a stub anywhere nor anyone that is willing to sell one. It seems everyone wants to do a service call. Anyway, I am wondering if perhaps part of the issue is we do not know what the proper name of it is. I am in E.KY and around here they just call it a stub kit. It is NOT the service valve. If anyone can help point me in the right direction I would greatly appreciate it. It seems insane to have a unit for over 2 years and not once been able to connect it. Obviously the one shown id the old connector.
We believe it to be a 1/2 inch nut on the line.
