How do the fittings, AN or hose barb, get mounted in the evaporator
cores?  Welded, brazed?  Where is the optimum location for the fittings?  I
have seen several positions for the fittings.  I am mounting two of the
cores similar to those used in the RVs next to each other and would like to
locate the inlets and outlets. Thanks for any help.

Hi Joe,
 
The fittings are welded (TIG) to the evap cores.  One fitting has to be placed on the end of each tank, but that's about the end of the rules.  Which end of the tank you use, will likely be determined by the space you have available.  In my case, I have the water cores oriented such that the tanks are on the left, and right, so the fittings either have to be on the top end of the tanks, or bottom.  Traditional radiator logic would say to bring the hot water in on the top of one tank, and take the cooler water out the bottom of the other tank, but I just don't have room for fitting on top.  I just put them both on the bottom, and it works just fine.  In other words, put them wherever they'll fit. 
 
Cheers,
Rusty (have TIG, will weld)
