The unit in the attached picture has two 6" return ducts coming off the plenum, they are currently right next to each other in the middle of the plenum. The main return you will see is fed from the underside right at the start of the plenum.
The 6" returns are undersized for the rooms they are serving, so I am replacing the 6" return ducts with 10" returns. Should I keep the same take-off locations, or is there a better placement for them on the plenum I should consider?
