Locate the three anchor points (see Figure 1-5) and dig three holes 600 mm square
by 600 mm deep. Fill the holes with concrete and install the eyebolts as shown in
Figure 1-6.
Figure 1-6 Ground Anchor Installation
1.7 Tower Assembly
To install the tower and guy ropes (if fitted) you will need:
Two 9/16" open end spanners
A 9/16" socket and ratchet
A tape measure
A 1/8" Allen Key
A flat blade screwdriver
UV-resistant wire ties
A pair of cutters
A 7 mm nut driver
A pair of wire rope cutters
A spirit level
A pair of pliers
Having previously installed the base and bottom tower section, remove both bolts
from the rear tower leg. Remove the lower bolts and loosen the upper bolts in the
other two legs so that the bottom tower section is free to hinge – see Figure 1-3.
Tilt the bottom tower section to the ground and assemble the middle section.
Note that only
one
bolt is required per leg for this (there may also be a blind hole
in each leg which should
not
be drilled out). See Figure 1-7, below. Do not attach
the top mast section to the main mast yet, as you may need to attach mounting
arms and sensors to this section as detailed in Section 2.
