Return air would be a 452 sq in. This is a general requirement there are other variables related to the duct system design.
Customer: replied 2 years ago.
so a 24 x 18 inch single grill return for the return air plenum is the minimum area for this unit, correct?
Expert:  Rick replied 2 years ago.
22 X 22 would be more like it but 24 x 18 is close enough generally speaking.
