(2) If the bottom return air is desired, just change the place of the rectangular flange and the
return air cover plate.
(3) Connect one end of the return air duct to the return air outlet of the unit by rivets and the
other to the return air louver. For the sake of the convenience to freely adjust the height, a
cutting of canvas duct will be helpful, which can be reinforced and folded by 8# iron wire.
