STEP 17.
Install the lowest vertical operating-pipe
section by threading one end of the pipe into the
coupling on the operating handle. Approximately
¼-inch (6 mm) of thread should extend through
the coupling. Tighten the locknut. See Figure 19.
STEP 18.
Insert the upper end of this pipe section in the
lowest rod-guide coupling (or, if only one
vertical pipe section is used, the bell-crank
coupling) and, while holding the operating
handle at a point approximately 20 degrees from
the
Closed
position, tighten the rod-guide (or
bell-crank) clamp bolt. See Figure 20.
NOTICE
Do not tighten the piercing set screw at the
top of the lowest section of vertical operating
pipe until satisfactory operating-handle
adjustment is attained .
STEP 19.
Fasten the free end of the grounding strap to the
lowest vertical operating-pipe section a few
inches above the operating-handle assembly
with the U-bolt connector provided for this
purpose. See Figure 21. Then, connect the lower
end of the strap to a suitable earth ground, using
the grounding connector provided at that end of
the strap .
