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 4.4.3.1.
Fig 4.4.3.1
(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.
(5) Select the appropriate installation way based on actual construction and maintenance needs,
as shown in Fig 4.4.3.2.

4.4.4 Installation of Fresh Air Duct
(1) If a fresh air duct is needed, remove the fresh air baffle as shown in Fig 4.4.4.1. If a fresh air
duct is not needed, block the gap on the baffle with sponge.
(2) Install circular flange so that fresh air duct can be easily connected, as shown in Fig 4.4.4.2.
(3) Both air duct and circular flange need to be well-sealed and insulated.
(4) Fresh air should be the air that has been filtered.
