2.1.4 Design and Connection of Duct
 The duct design must comply with the national heating air conditioner pipeline design specifications.
 The duct accessories and materials must be produced by professional manufacturers.
 In order to prevent air flow shorting, do not keep the air inlet pipe near the air outlet pipe.
 Install a filter at an easy-to-maintain place such as intake pipe. (Otherwise, the duct will gather on the air
heat exchanger and lead to fault and water leak of the air conditioner.)
 In order to suppress noise effectively, install noise suppression and sound insulation devices, especially in
the noise-sensitive spaces such as meeting rooms.
 For connection of the flange plane, use non-flammable canvas adapter to prevent transmission of vibration.
For its size, see the indoor unit outline diagram. Use M6X20 screws (configured on site) for connection.
 All pipelines must be connected closely and soundly without leak of air. The pipelines must be adiabatic and
free from condensation.
