Basic Installation Instructions
Prepare the work site.
Tip: This will involve excavating the appropriate dimensions to accommodate the grease interceptor, the inlet and outlet pipes – all at proper depths to result in easy access to sediment removal openings. Be sure to compact the soil bed to withstand the pressure of the interceptor, its contents, and any applicable impact of above-grade traffic.
Unload the precast grease interceptor.
Tip: One person should be stationed at the installation site and another person should be located on or near the delivery flatbed trailer to guide the lift operator. The lift should be placed near the center of gravity of the interceptor so that when suspended, the structure is nearly level. Place it in the installation area, guided by the designated person. The inbound and outbound openings should be guided to the proper orientation of the excavation.
Instal the inbound, outbound and access pipes.
Tip: Do not proceed to the final step until all has been properly reviewed by the applicable inspectors.
Backfill the exposed area.
Tip: Compact the top layer until it can withstand any applicable traffic and other pressure.
