Installation
Installing the Vertical Operating Pipe
Follow these steps when installing the vertical operating
pipe:
STEP 10.
One of the pipe sections furnished is threaded at
one end to accommodate the operating handle
assembly. See Figure 11. Install this section of
pipe last, with the threads at the lower end.
If only one vertical operating-pipe section
is required, proceed to Step 13 on page 15.
STEP 11.
Position and install the rod guide(s) with the
arm pointing upward on the pole or structure in
accordance with the dimension shown on the
erection drawing. See Figure 12. A positioning
stud is furnished which holds the rod guide arm
at 45 degrees.
STEP 12.
Install the upper section of vertical operating
pipe between the interphase drive lever
cou pling and the uppermost rod guide, with the
rod-guide arm pointing upward at a 45-degree
angle. See Figure 13. (A positioning stud is fur-
nished that holds the rod guide at 45 degrees.)
Follow the directions in the “Installing Pipe
Couplings with Piercing Set Screws” section on
page 12.
Torque the clamp bolts to final tightness.
Then, tighten the piercing set screws, pierc-
ing the pipe, and continue turning until a firm
resistance is felt.
If more than one rod guide is used, install
vertical operating-pipe sections between the
rod guides in the same manner.
