MAINTENANCE
No outside trim supplied for EO (exit only) application
Von Duprin 2227 exit devices are designed and built to be maintenance free; however, such
factors as installation, severity of use, environmental conditions, and changes in the condition of
the door opening may require that maintenance and/or device adjustment be performed. The
following guidelines are recommended to the building owner to insure proper device operation:
1. Check device operation for smooth operation periodically.
2. Check strikes (keeper) and latches to insure they are secure.
3. Check latches and other moving parts for binding or sluggish operation due to dirt or chemical
buildup. Clean parts with soap and water and then lubricate with graphite-based or silicone
lubricants. Do not use petroleum-based lubricants.
