It is the most insanely complicated and ill-conceived system I've ever seen. It does have two gas ports, but the one you would normally charge through (low pressure side) is hidden up by the bulkhead and impossible to reach with the normal connector. Why they would do that is a mystery. My AC guy charges it through the high-side port on the condenser which he says is stupid and the wrong way round but the only possible way to do it. He has to put the gas bottle in a bucket of hot water to get enough pressure for it to go in!
Don't even get me started on the nightmare of ducts and servo motors and that stupid coolant valve block
