Installation
Installing the Vertical Operating Pipe
Step 9
S&C recommends making up each coupling
connection as work progresses from the top
down. Starting with the universal coupling
connecting the switch to the upper section of
vertical operating pipe, and continue with the
coupling between the upper section of vertical
operating pipe and the first lower section.
Continue down to the last section of pipe, and
end with the rotating operating handle.
This makes it easier to adjust for variations
in the surface and height of the wood pole or
mounting structure.
Insert the uppermost section of vertical oper-
ating pipe into the universal coupling attached
to the underside of the outboard bearing assem-
bly. See Figures 6, 7, and 8 on page 12. Back the
piercing set screw out of the body of the pipe
coupling clamp before tightening the bolts.
Torque the clamp bolts to their final tight-
ness, and then tighten the piercing set screw,
piercing the pipe. Continue turning until a firm
resistance is felt.
Step 10
Attach a pipe-to-pipe type universal coupling
to the lower end of the uppermost section of
vertical operating pipe. See Figure 10. Back
the piercing set screw out of the body of the
pipe coupling before tightening the coupling
clamp bolts.
Torque the clamp bolts to final tightness, and
then tighten the piercing set screw, piercing the
pipe. Continue turning until a firm resistance
is felt.
