should be at the same height as the top of the finalized concrete
block. Protect the threads of the bolts above the orientation plate,
for example, by taping them. Also check the correct alignment of
the foundation assembly with the orientation plate. "N" should face
north and "S" should face south.
7. For the guy wires, fix the foundation bolt (number 2 in Figure 10
on page 43) to the plate with a nut (3). Fix the eye nut (1) to the
other end of the foundation bolt. Level the assembly so that the top
of the bolt will be 40 mm above the concrete in the finalized block.
The eye nut will then be one centimeter above the finalized
concrete block.
8. Pour in the concrete. Finish the concrete block.
Using Existing Concrete Block
1. Drill holes with a diameter of 25 mm into the concrete block using
the orientation plate as a guide. Make sure that the depth of the
holes is 240 mm (±5 mm).
