Attach the sweep couplers to the plastic sweep tubes
Each of the sweep coupler halves will have a notch in the mold on one side. It is
critical
that these
notches are pointing towards the sweeps or they will not work properly. See
Figure 4.20
for the
location of the mark. Be certain that each half of the coupler has the mark facing the sweep tube!
Insert the four 60
-
0156 #6 x
2”
screws. Place the screws so that the threaded portion of the screw is
facing downward. Apply anti
-
seize to the threads and place the Nylock nuts on. Tighten so the
polyethylene tube just slides into the clamp, without the clamp falling off as showin in
Figure 4.22
.
Do
not tighten enough to deform the polyethylene
. Repeat for other side of sweep tube.
Attach a coupler as shown in
Figure 4.21
to one of the four
170”
telescoping pole tips that has been
prepared previously (see Section 4.0). For aesthetic reasons it is nice to have all of the screws in the
sweeps and metal brace be oriented the same. To do this, make two of the sweeps turn one way and
two the opposite way. One of each type is shown in
Figure 4.13
. Be careful not to displace the blue
silicone wrap when placing the coupler onto the pole tip. Slide the coupler on until the coupler hits the
black electrical tape edge marking 1.70 inches from the pole tip. It is acceptable for a small amount of
blue silicone wrap to protrude from the joint as shown in
Figure 4.33
.
