Install Air Diffusers for Best Airflow Direction1. Remove the top diffuser, Part # 186458, from its packaging.
2. Check the top diffuser’s fittings and insertion holes on the Liebert XDH to determine how the
diffuser should be installed—the diffuser may be attached only one way on the top half of the
Liebert XDH.
3. Rotate the diffuser 180 degrees and press it against the lower half of the Liebert XDH until it
snaps into the fittings (see Figure 10).
The vanes in the diffuser now point in the opposite direction.
4. Repeat Steps 1 through 3 to install the bottom diffuser, Part # 186459, on the upper half of the
Liebert XDH.
