12. Maintenance
12.1 Procedures
12.1.1 Dust Tray or hopper: The dust trays, or hopper contents should be checked and emptied periodically. The frequency of this step will depend on the number of shifts operating and conditions in the plant. However, it is a good practice to frequently remove residual build up. 12.1.2 HEPA/SAFETY Filters: The HEPA/SAFETY filters, if equipped, are located on top of the unit (inside the HEPA/SAFETY module). Periodically, these filters should be inspected and replaced. Condition of the HEPA/SAFETY filter will generally be a function of the magnehelic gauge (for the HEPA/SAFETY filters – NOT the cartridge filters) reading. To examine: • Remove the two wing nuts for each filter • Lift off the filter strut.
• Remove HEPA/SAFETY filters • Install new HEPA/SAFETY filters • Reinstall HEPA/SAFETY filter strut • Reinstall the two wing nuts for each filter.
12.1.3 Spark Baffles: The spark baffles, if equipped, are located on front of the Spark Eliminator inlet plenums. These baffles should be periodically cleaned with mild soap and water. To examine: • Pull the baffle filters out of the inlet plenums. • Inspect for build-up and cleanliness. • Wash with soap and water. Let filters dry before reinstalling. • Reinstall the filters. 12.1.4 Cartridge Filters: The cartridge filters will need to be replaced periodically. The frequency varies from a few weeks to a few years, depending on factors such as density of fumes/dust, particle size, humidity of air, oil or grease contents of matter, etc. To change out: • Open the dual-hinged inlets by opening the clamps at the top and bottom of the inlets. • Pull both cam lock levers OUT. The filter guide bars should drop down. • Slide the cartridge filters out of the unit. Dispose appropriately. • Slide the new filters into the unit. Be sure to push the back row of filters as far back as possible. • Push both cam lock levers IN to clamp the filters to the tube sheet. • Close the inlets and clamp to the dust collector body. 12.1.5 Drain Valve: Periodically open the drain valve attached below the compressed air reservoir to drain the liquid build-up in the air tank.
