The supply and return air duct systems should be designed
for the CFM and static requirements of the job (see Table
3).
They should not be sized to match the dimensions
of the duct connections on the unit. The return duct must
be sealed to the unit casing and terminate outside the space
containing the unit.
Do not screw into the side of the drain pan, or into the
indoor coil.
