Installation of air-inlet grille
The angle of air-inlet grille should be
parallel with that of air inlet direction,
otherwise it will cause more noise.

1. Installation of the duct work: With a square supply duct, the bore shouldn't be less than the sizes of air outlet duct.
2. Installation of the air return duct: Connect one side of the air return duct to the air return of the indoor units with rivets,
The duct size shouldn't be smaller than the outlet/inlet size of the indoor unit, as shown in Fig. 1.
3. Insulating Supply Ducts: Supply and return air ducts should be insulated.
