4-4.8 Electric and Cable Operated Control Heads
The following procedures are to be performed before attaching control head to the cylinder
valve or stop valve (refer to Figure 4-27):
1. Remove four screws holding cable housing cover on control head. Remove cover.
2. Position control head in the approximate installed position at the carbon dioxide cylinder
valve or stop valve pilot control port, but do not assemble onto the pilot control port.
3. Check that the control head is in the "SET" position.
4. Assemble the pull cable conduit to the conduit connection on the control head.
Note: The corner pulley installation should allow flexibility for installation and removal of the
control head from pilot control port.
5. Feed cable into control head through the hole in the operating lever.
6. Feed cable through the cable clamp. Pull cable taut, allowing approximately 1/4-inch to
1/2-inch clearance between the cable clamp and the operating lever. Tighten set screws in
cable clamp to secure cable to clamp.
7. Cut off excess cable.
8. Verify manual remote cable operation to ensure control head actuates and all cable clamps
are tight.
9. Pull cable back to its normal set (un-operated) position.
10. Reset control head.
11. Replace control head cover.
12. Examine seal wire at locking pin. Ensure it is intact.
13. Make electrical connections.
14. Assemble control head to cylinder or stop valve pilot control port. Tighten swivel nut
securely.
WARNING
Before installing control head on the carbon dioxide cylinder valve, ensure that
the control head is in the “SET” position (actuating pin is in the fully retracted
or “SET” position). Failure to position control head in the “SET” position will
result in accidental carbon dioxide cylinder discharge when the control head is
installed on the cylinder.
