Remove the manhole covers and maintenance process comprises the removal and open all access hatches. replacement of each BayFilter cartridge and the cleaning of the vault or manhole with a vacuum buck. 2. Before entering the system make sure the air is safe per OSHA Standards or use a breathing The maintenance cycle of the BayFilter system will be apparatus. Use low 02, high CO, or other applicable driven mostly by the actual solids load on the fitter. The warning devices per regulatory requirements. system should be periodically monitored to be certain 3. Using a vacuum truck remove any liquid and it is operating correctly. Since stormwater solids loads sediments that can be removed prior to entry. can be variable, it is possible that the maintenance cycle could be more or less than the projected duration. BayFilter systems in volume -based applications are designed to treat the WOv in 24 hours initially. Late in the operaflonal cycle of the BayFiter, the ' flow rate will diminish as a resu8 of occlusion. • When the drain down exceeds the regulated _ - standard, maintenance should be performed. When a BayFiher system Is first Installed, it is recommended that it be inspected every six (6) months. When the filter system exhibits flows below design levels the system should be maintained. Filter Cartridge replacement should also be Considered when sediment levels are at or above the level of the manifold system. Please contact the BaySaver Technologies Engineering Department for maintenance cycle estimations or assistance at 1.800.229.7283. 4. Using a small lift or the boom of the vacuum buck, remove the used cartridges by lifting them out. BAYSAV ER TECHNOLOGIES' S. Any BayFilters that cannot be readily lifted 9. The used BayFilters must be sent back directly out of the vault should be removed from to BaySaver Technologies forexchange/ their location and carried to the lifting point using the recycling and credit on undamaged units. Trolley system installed In the Vault (if applicable). 6. When all BayFilters are removed, remove the balance of the solids and water; then loosen the stainless clamps on the Femco couplings in the pipe manifold; remove the drain pipes as well. Carefully cap the manifold and the Femcos and rinse the floor removing the balance of the collected solids. 10. Contact BaySaver Technologies for Exchange Filter pricing and availability at 1.800.229.7283. 7. Clean the manifold pipes, inspect, and reinstall. 8.
