INSTALLATION PROCEDURE1. Ensure the trench excavation is at least 300mm wide on each side of the chamber base considering the characteristics ofnatural soil.2. Level the trench bottom and prepare bedding of minimum 100mm sand. Ensure that sand and trench base do not havesharp edges, big size stones or sand particles.3. Clean the chamber base socket and riser pipe. Then apply lubricants on the rubber ring.4. Position the chamber on the bed and connect the main trunk sewer line to chamber inlet. In case, sand bedding is low, increase the height and connect the chamber base inlet to main sewer line.5. Use the spirit bubble level scale for leveling the top of the chamber base.6. Cover the main sewer pipe 200-300mm with backfilled/sand material.7. The chamber is now firmly set on the main sewer line and is ready to connect laterals.8. Connect laterals and trunk outlet to chamber base sockets. All unused inlets, if open, should be plugged.9. Cut the inspection chamber with the help of a fine-toothed saw to fit into the required height.10. Inspection chambers are provided with ribs at a distance of 50mm for 600mm diameter and at 32mm for 315mm diameterto cut according to invert depth suitability as per site condition.11. Fill granular material (similar to bedding material) around the chamber.12. Backfilling of the trench should be carried out in successive uniform compacted layers of 200-300mm with good practicearound entire circumference of the inspection chamber. Ensure backfill material from stone size of 40mm (1 1/2"), lumps claygreater than 90mm (3") and timber or other material that could prevent sound compaction.13. Prevent the compactor equipment/ backfill material from knocking with inspection chamber during compaction & backfill.14. It is necessary to compact the soil with the minimum Standard Proctor Density (SPD) of 90% with regular to heavy traffic.15. Keep backfill level 60mm/ 90mm below the top of the inspection chamber.16. Put the RCC/ Fulcrum concrete ring having minimum height of 85mm around the top of inspection chamber. The purpose ofRCC/ Fulcrum concrete ring is to transmit the vehicle load towards the lower layers of the road, thus avoiding direct loadingon the chamber.17. The distance between outer diameter of inspection chamber and inside of fulcrum concrete ring must be minimum 10mmon each side. This assures the weight (static load of chamber cover and vehicular load) is not transferred directly onchamber assembly.
