4.4.3 Installation of Air-return Duct
(1) Square flange is defaulted to be fitted on the back before ex-factory. Air-return cover is on
the bottom, as shown in Fig 4.23.
Fig 4.23
(2) If air return from the bottom is needed, switch the positions of square flange and air-return
cover.
(3) Use a clincher to connect air-return duct to the air-return opening of indoor unit. The other
end of air-return duct connects with the air-return louver. In order to adjust the height
conveniently, you can make a folded canvas duct and have it strengthened by 8# iron wire.
(4) Air return from the bottom will produce more noise than air return from the back. So we
suggest you to add a noise damper and static pressure case to lower noise if you choose air
return from the bottom.
