1. Select the appropriate location for the hopper and place it on solid level ground. Ideally the hopper should be about 6' (2m) from the excavation. Check the wheels if necessary to stabilize the hopper. (Figure 11)

2. Install the vacuum pump so that it points away from persons in the area. Be sure that an exhaust bag is securely installed. Secure pump with elastic hold down. (Inset) Check all neoprene sealing surfaces (upper lid, lower door) for snug fit. Damaged seals or improper attachment will rob system performance. (Figure 12)
