Installing Pipe Couplings with
Piercing Set Screws
WARNING
Failure to properly install pipe couplings with pierc-
ing set screws can cause slippage of operating pipe,
resulting in improper operation of the switch, arcing,
equipment damage, or electrical shock.
To properly install piercing set screws:
1. Make sure the cutting tip of the piercing set screw does
not protrude through the body of the clamp.
2. Insert the operating pipe section into the coupling and
nger-tighten the clamp bolt(s).
3. Adjust the operating pipe to the correct length. Then,
tighten the clamp bolt(s) to nal tightness.
4. Tighten the piercing set screw, piercing the pipe, and
continue turning until a rm resistance is felt.
5. Make sure the clamp bolt(s) are tight.
See Figure 16.
