3 Outdoor Unit Ducting and Shielding
3.1 Ducting Requirements
Depending on the height of adjacent walls relative to the height of the units, ducting may be required to ensure proper air
discharge. In the situation depicted in Figure 3-3.1, the vertical section of ducting should be at least H-h high.

3.2 Design Considerations
Outdoor unit ducting design should be take account of the following:
Each duct should contain no more than one bend.
Vibration isolation should be added to the connection between the unit and the ducting to avoid vibration/noise.
Louvers are installed for safety, they should be installed at an angle no greater than 15° to the horizontal, to minimize
the impact on airflow.
