7.1.1 Base Installation
The UT10 tower attaches to a user-supplied concrete foundation as shown in
FIGURE 7-1. The base brackets, anchor bolts, and nuts are included with the
tower.
1. Dig a hole 24 inches square and 24 inches deep. Lighter soils will require
a deeper hole.
2. Assemble the J-bolt template as shown in FIGURE 7-2. Begin by
threading two 5/8 inch nuts onto each J-bolt, followed by a 5/8 inch
washer. Next, place a template piece over the J-bolt, followed by another
5/8 inch washer and a 5/8 inch split lock washer. Thread a third 5/8 inch
nut onto the J-bolt just until the bolt is even with the top of the bolt. Once
all three J-bolts are assembled, slide them together as shown in FIGURE
7-2. Align each J-bolt so the angled portion is pointing outward and
tighten the lower nuts to secure the assembly.
