Where is the liquid line sweat on adapter to compression fitting on coil?

Goodman coils are designed to accept either a field-installed piston or a TXV valve. In both scenarios, it is necessary to remove the compression fitting to accomplish this. These END series coils from AirQuest are different in that they come with a TXV valve already factory-installed. Because of this, they do not need a removable sweat-on compression fitting coil adapter that the typical Goodman coil has. All you need to do is simply braze the liquid line to the 3/8 connection on the coil and you are done.

To help illustrate it better, here are some images that show the differences between a Goodman and an AirQuest assembly:

This first image is what the Goodman assembly looks like. The below image is what an AirQuest assembly looks like.

AirQuest's coil is different because the TXV (highlighted yellow) is already there. There is no need to install anything to meter the flow of refrigerant into the coil. All that remains is to braze the 3/8 liquid line into the fitting (circled in red).
