Indoor Unit
169
Super Match
 ■ Each of the air sending duct and air return duct shall be xed on the prefabricated panel of the oor by the iron 
bracket. The recommended distance between the edge of the air return duct and the wall is over 150mm.
 ■ The gradient of the condensate water pipe shall keep over 1%. 
 ■ The condensate water pipe shall be thermal insulated.
 ■ When installing the ceiling Conceal indoor unit, the air return duct must be designed and installed as gure 
shown.
Note:
 ■ When connecting the short ducts, use the low static terminals, which color is white.
The distance L from the air outlet of the duct to the air outlet of the air conditioner shall be no more than 0.5 m. 
 ■ When connecting the long ducts, use the middle static terminals, which color is red.
The distance L from the air outlet of the duct to the air outlet of the air conditioner shall be no more than 2.0 m.

1. Installation of air sending duct
 ■ This unit uses rounded duct, the diameter of the 
duct is 180mm.
 ■ The rounded duct needs to add a transition duct 
to connect with the air-sending duct of indoor unit, 
then connect with respective separator. As Figure 
shown, all the fan speed of any of the separator’s 
air outlet shall be adjusted approximately the same 
to meet the requirement for the room air conditioner.
2. Installation of air return duct
 ■ Use rivet to connect the air return duct on the air 
return inlet of the indoor unit, then connect the other 
end with the air return blind as Figure shown.
3. Thermal insulation of duct
 ■ Air-sending duct and air return duct shall be 
thermally insulated. First stick the gluey nail on the 
duct, then attach the heat preservation cotton with 
a layer of tinfoil paper and use the gluey nail cap to 
x. Finally use the tinfoil adhesive tape to seal the 
connected part. As Figure shown.
