If using a gravel foundation, the hole for the pad must be deep enough to place the gravel before installing the
pad template. Check local codes for exact specifi cations.

4. Dig the trenches for the sweep conduits. Consult your local codes for the required depth,
fi ll material, and back fi lling.
5. Install the wooden perimeter frame in pad opening.
6. Verify that the top of the pad is 4 inches above grade to minimize debris buildup around
the base of the cabinet.
7. Place the pad template in pad opening and adjust the template so the tops of the four
threaded fasteners are level with the top of the wooden frame.
8. Plug the threaded inserts.
9. Pour the concrete, smooth the surface of the pad, and let the concrete cure.

1. Determine the size of the pad you need. Typically it is best to leave at least 6 inches
of space between the outside of the cabinet and the edge of the pad. Occasionally,
you might want to extend the pad in one or more directions for ease of access during
maintenance.
2. Using the physical placement of the mounting bolts in the pad template, calculate the
exact dimensions of the pad, taking into consideration the size of the wooden frame used
around its perimeter. Measure the overall pad dimensions from the inside of the wooden
frame.
3. Using the dimensions calculated in step 2, excavate the site for the pad.
