Just a quick question..If an ADP coil says "TXV installed" is that TXV mounted inside the case? Reason I ask, my entire Infinity system was just replaced and this time they used an ADP coil. The last coil had the TXV mounted on the outside where the line exits the case, this one, both lines go straight into the case with no valve. Before I get too excited, do they put them inside the case where you don't see them? I have the model number at home, but this is one of the enclosed case A coils with both drain pans. Also I think there might be an installation problem, about an hour after the installer left we noticed the emergency drain running and went upstairs and the overflow pan was full. Water was running out of the bottom of the coil. It appears the regular drain is okay. I was reading the manual, and it states that if the coil is mounted with the top of the "A" toward the fan that there should be at least 12" between the blower case(furnace) and the coil. They mounted it right to the furnace. It also says something about putting silicone between the two drain pans if the bottom one is used as a backsplash. I bet they didn't do that..Could that be the problem? They are coming back Saturday to address some ducting issues so will call him and tell him it's leaking..Hopefully it's something simple he missed.
