9.1.7Replacing Dust Filters

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 75).

2.Remove one bracket and loosen the screw on the second bracket. The second bracket need not be removed (see Figure 75).

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.
