3.2Excavation
The excavation must be large enough to provide a fill base that will maintain stability for the FMS and the cabinet mounted on it. There must be room for 12 inches (30.5 cm) of fill below and on each side of the FMS. The excavation dimensions for the FMS 20000 are shown in Figure 4. Excavate a rectangular hole for the FMS.

Figure 4. Excavation Recommendations for
3.3Placement of the FMS
Danger: Use adequate lifting equipment when installing the FMS. Do not stand in the hole while placing the FMS in position. An unexpected shift of the FMS could result in personal injury.
Use the following procedures to place the FMS into the excavation.
1.Fill the bottom of the hole with stone aggregate, tamping it as it is filled to build a 12 inch (30.5 cm) layer with a level surface. The stone aggregate will provide a stable base to support the FMS.
