nuts (6), which are fixed to the square metal plate (3).
5. Fix the orientation plate (2) to the upper ends of the foundation
bolts (1) with eight nuts (4 and 5), see Figure 41 below. The top
of the bolt should be approximately 80 mm above the

6. Install the foundation assembly into the mould so that the
foundation bolt threads stand above the surface, see Figure 38
on page 54. The orientation plate (number 4 in Figure 42 on
page 58) should be at the same height as the top of the finalized
concrete pad. Also check the correct alignment of the foundation
assembly with the orientation plate (number 4 in Figure 42 on
page 58). "N" should face north and "S" should face south.
