8.2.2 Dust Filter for 10-30kVA

Installing the two dust filters in the Liebert NX requires only a Phillips screwdriver. Each filter is

held in place by a bracket on either side of each filter. To install each filter:

1. Open the UPS door and locate the filters (on the back side of the front door; see Figure 43).

2. Remove one bracket and loosen the screw on the second bracket. The second bracket need not be

removed (see Figure 43).

3. Remove the dust filter to be replaced.

4. Insert the clean filter.

5. Reinstall the bracket, tightening the screw securely.

6. Tighten the screw on the second bracket.
