Hey please!! Need help!! I have a 4 ton heat pump with the return coming from the bottom, it needs to sit on a 13 inch high box to accommodate a 10x30 return drop and the unit is 49 inches tall, so 62 inches total height. My ceiling is 77 which leaves me 14 inches for a plenum and my trunk line is 10 inches tall. I wanted to do an offset to the trunk line to give good air flow but we're talking like 1-2 inches from the bottom of the plenum. Is that a problem? This video is the closest thing I could find to any content discussing this and it mentioned 10 inch minimum which would be impossible even with an 8 inch tall trunk. Let me know please!! Any advice? Am I okay?
If you dont have that 10 inch min when you use a 45degree taper on the 1-D, should you stick with stabbing into plenum to preserve 10 in height, or go with taper and sacrifice soem of theta height to below 10 inches ?>
What are you suppose to do when the AH is in the worst spot of a U shaped house so you have to go two directions from the plenum

I would recommend some taper. Just realize it may not be a 10’TEL then. Somewhere between 10-35’ is likely.
Funny the takeoffs have no option for a horizontal unit in an attic with a square to round on the end.
