4.2 Changing the Air Intake Location
The Liebert XDV comes from the factory with the air intake on the rear of the unit. If required for
your application, this can be changed so that the Liebert XDV takes in heated air from the bottom.
This is done more easily and safely before the unit is mounted on a computer cabinet.
To change the air intake:
1. Loosen the six screws holding the grille on the rear of the Liebert XDV (see Figure 9).
2. Remove the grille and lay it aside for use later.
3. Remove the channel bracket holding the two solid metal plates to the bottom of the Liebert XDV.
It is secured with two screws, one on either end.
4. Lift the two solid plates out of the bottom of the Liebert XDV.
5. Optional—replace the channel bracket, securing it with the two screws removed in Step 3.
6. Lay the perforated grille down with the screws pointing up
7. Lay the two solid plates on the grille with the screws through the matching holes of the plates.
8. Hold the grille and plates together and attach the assembly to the rear of the Liebert XDV with
the screws.
