A CAUTION The maximum length of the duct means the maximum length of the supply air duct plus the maximum length of the return air duct The duct is rectangular and connected with the air inlet outlet of the indoor unit Among all supply air outlets at least one should be kept open 2 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 Figure 3 1 21 Rectangular Flange Rear Return Air Figure 3 1 21 3 Ifthe bottom return air is desired just change the place of the rectangular flange and the return air cover plate 4 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 5 More noise is likely to be produced in the bottom return air mode than the backward return air mode so it is suggested to install a silencer and a static pressure box to minimize the noise 6 The installation method can be chosen with considering the conditions of the building and maintenance etc as shown in Figure 3 1 22 56 U Match Series DC Inverter Service Manual Z a rl LZ A S 7 lo Od eN Supply air SSe l Return air Install the return air duct b Figure 3
