9.3.2 Air Filters
The air filters must be inspected and serviced on a regular schedule. The period between inspections
will depend upon environmental conditions. Under normal conditions, the air filters will require
cleaning or replacement approximately every two months.
All Liebert eXM models have replaceable filter elements behind the grille in the front of the unit. This
element can be changed with the UPS operating by opening the outer door. The Liebert eXM’s air
filters are washable and reusable. Two sets of air filters are shipped with each Liebert eXM.
Abnormal or dusty conditions will require more frequent cleaning and replacement of air filters.
Inspect installations in new buildings more often, then extend the inspection period as experience
dictates.
Replacing Air Filters
Installing the two air filter sizes in a Liebert eXM requires only a Phillips screwdriver. Each filter is
held in place by a bracket on either side of each filter. Two sets of washable and reusable dust filters
are shipped with each UPS. Refer to 9.3.2 - Air Filters for details about filter maintenance.
To replace a filter:
1. Open the UPS front door and locate the filters on the back side of the front door (see Figure 40).
2. Remove one bracket and loosen the screw on the second bracket. The second bracket need not be
removed.
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.
