 Installation of return air duct 

‹

  The square flange is mounted on rear section when it is shipped. The return air inlet cover plate is 

mounted beneath, as shown in Fig. 1-1-14.   

 

Figure 1-1-14 

‹

  If down return air inlet is to be used, just change the position between square flange and cover plate 

of return air inlet.   

‹

  Rivet the return air duct to the return air inlet of indoor unit and connect another end to return air 

window. For free adjustment of the height, you may fabricate a section of canvas air duct and 

reinforce with 8# iron wire in folded form. You may select the installation methods in overall 

consideration of the building and maintenance conditions, as shown in Fig. 1-1-15.
