Installation of Electric/Cable Operated Control Head,

(P/N 81-895630-000 and WK-897494-000)

Follow all instructions contained in the main body of the DIOM up to this section. The following
procedures must be performed before attaching a control head to a cylinder valve.
Before installing a control head on a nitrogen driver cylinder valve, ensure the
control head is in the SET position (that is, the actuating pin is in the fully
retracted or SET position). Failure to position the control head in the SET
WARNING
position will result in accidental discharge and possible personal injury when
the control head is installed on the driver valve.
1. Remove the four screws holding the cable housing cover on the control head. Remove the
cover.
2. Position the control head in the approximately installed position at the agent cylinder valve
control port but do not assemble onto the actuation port of the agent cylinder valve.
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.
5. Feed the cable into the control head through the hole in the operating lever.
6. Feed the cable through the cable clamp. Pull the cable taut, allowing approximately 1/4 in
to 1/2 in clearance between the cable clamp and the operating lever. Tighten the set screws
in the cable clamp to secure the cable to the clamp.
7. Cut off any excess cable.
8. Verify the manual remote cable operation to ensure control head actuates and all cable
clamps are tight.
9. Pull the cable back to its normal set (non-operated) position.
10. Reset the control head.
11. Replace the control head cover.
12. Examine the seal wire at the safety pull pin. Make sure it is intact.
13. Insert the Control Head Monitor between the control head and the cylinder valve. This is
similar to the order of installation shown in Figure 3.
14. Assemble the control head to the cylinder valve actuation port. Tighten the swivel nut se-
curely.
Note: When installed, the Control Head Monitor does not sit completely snug against the
valve. This play allows for easier attachment of conduit to the component.
The placement supervision signal is not a substitute for ensuring proper
interlock of the actuator plunger to the valve core assembly. Make sure the
WARNING
control head is properly seated.
15. Make all electrical connections as outlined in the DIOM.
For US and Canada Explosion proof installations, seal all conduits within 18
inches from the end of the component.
