3.0.2 Installation of Concrete Base
1. The ET Tower attaches to a user supplied concrete foundation
constructed as shown in Figure 11.
2. Construct the concrete form with 2" x 4" lumber and 16p nails.
3. Assemble the template and anchor bolts. There should be two nuts
below and one nut above the template on each bolt.
4. Clear an area large enough to set the form at the desired elevation.
5. Dig a hole 2 feet x 2 feet x 2 feet. Lighter soils may require a
deeper hole. About 20 inches below the top of the hole, gouge a
small cavity in one wall of the hole. The cavity should be about 4
inches deep and just large enough in diameter to insert one end of
the conduit. Make certain the cavity "points" in the direction from
which power and communications cables will come. For example
the cavity will “point” towards a valve box if one is being used.
6. Center the form over the hole. Adjacent to the form, drive four
stakes into the soil. Secure the leveled form to the stakes with the
8p nails.
7. Cap the ends of the conduit with duct tape. Position the conduit
and wire into place by securing the wire to nails in the form.
8. Fill the hole and form with approximately ½ yard of concrete.
Screed the concrete level with the top of the form. Center the
template assembly over the conduit and press into the concrete.
Put 2 x 4 spacers between the template and the top of the form.
The bottom of the bolt threads should be about ½ inch above the
concrete. The template must be level in two dimensions. Use a
trowel and edger to finish.
9. Wait 24 hours before removing the concrete form. Wait 7 days
before mounting the WS-PRO2 Tower.
