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.
