UPM Air Filters

Figure 9-2. UPM Section Air Filter Locations

If the UPS is a Plus 1 model, check the Field Installed UPM (FI−UPM) air filter
(located behind the front panel) and wash or replace as necessary. See Figure 9-3
for the filter location. The FI−UPM filter size is 20"

44" 0.25". Contact an Eaton

service representative for replacement filter. To remove the filter:

Remove one top screw and two bottom screws securing the FI−UPM front
panel (refer to the Powerware 9395 Field Installed UPM Mechanical
Installation Manual). Lift the panel straight up to remove it from the panel
hanger bracket at the top of the cabinet.

Pull the foam filter over the screw heads on the cabinet mounted studs and
remove the filter from the cabinet.

Verify washed filter is thoroughly dry before reinstalling.

Push the washed or new foam filter over the screw heads on the cabinet
mounted studs until seated against the cabinet.

Reinstall the FI−UPM front panel removed in Step a and secure with the
retained hardware.

Record maintenance results and any corrective actions in a suitable log.
