4.4.3 Installation of the Return Air Duct
(1) The default installation location of the rectangular flange is at the back and the return
air cover plate is at the bottom, as shown in Fig 4.4.7.
Fig 4.4.7
(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.
(4) More noise is likely to be produced in the bottom return air mode than the rear return
air mode, so it is suggestive to install a silencer and a static pressure box to minimize
the noise.
(5) The installation method can be choosen with considering the conditions of the
building and maintenance etc., as shown in Fig 4.4.8.
