ANSUL FIRE PROTECTION
HALON 1301 SYSTEM CONTAINERS

1. Both the discharge port cap and the actuation port cap should be in place before moving or handling the cylinder or valve. The cylinder and valve combination should be properly secured at the work station so that the cylinder will not move if there is an accidental discharge. This is extremely important to avoid the possibility of serious injury.
2. Remove the discharge port cap and securely attach the proper discharge fitting adapter with the reclaim hose assembly. Any hose assembly valve should be closed at this time.
3. With the cylinder in the upright position initial discharge will be liquid product (Halon 1301) until the liquid level falls below the bottom of the siphon tube. Additional reclaiming will be vapor and, depending upon the type of reclaiming equipment being used, may require a switch over to a vapor recovery unit. Complete recovery is considered concluded when the reclaiming equipment vacuum gauge shows approximately twenty five (25) inches of vacuum.
4. The valve is maintained in a closed position due to the force applied to the larger surface area on the top side of the spool as compared with the bottom side even though the initial pressure is equalized. If there is a small leak of top side pressure the check assembly inside of the spool will allow for minor adjustments by seepage, and still maintain equal pressure to keep the spool in a dosed position.
5. To open the valve, top side pressure must be released by depressing the valve core located under the actuation port cap at the top of the cylinder. You will hear a small amount of gas being released followed by a rapid snap as the spool quickly rises to the open position. To start the flow of halon, the hose assembly valve should be opened.
6. When the cylinder is empty, close the hose assembly valve and remove the discharge fitting adapter with the reclaim hose assembly.
7. Cylinder should be pressurized with dry nitrogen to 100 to 150 psi through the outlet port. Top side pressure can then be applied with nitrogen to close the valve. This will prevent foreign matter from entering the valve and cylinder assembly. Keep moisture out of the cylinder and allow the valve to be opened later. Label cylinder as empty. This should be done if the cylinder will be reused.
8. Replace the discharge port cap and the actuation port cap to prevent damage to the threads and lost caps.

1. Both the discharge port plug and the actuation port plug should be in place before moving or handling the cylinder or valve. The cylinder and valve combination should be properly secured at the work station so that the cylinder will not move if there is an accidental discharge. This is extremely important to avoid the possibility of serious injury.
2. Remove the discharge port plug and securely attach the proper discharge fitting adapter with the reclaim hose assembly. Any hose assembly valve should be closed at this time.
3. With the cylinder in the upright position initial discharge will be liquid product (Halon 1301) until the liquid level falls below the bottom of the siphon tube. Additional reclaiming will be vapor and, depending upon the type of reclaiming equipment being used, may require a switch over to a vapor recovery unit. Complete recovery is considered concluded when the reclaiming equipment vacuum gauge shows approximately twenty-five (25) inches of vacuum.
4. The valve is maintained in a closed position due to the force applied to the seal body by the internal cylinder pressure.
5. To open the valve, top side pressure must be applied. Remove the actuation port plug. Securely attach a hose connected to a nitrogen cylinder and regulator assembly (with output of 800 psi). Slowly apply nitrogen pressure until the piston is pushed down releasing the seal and opening the valve.
6. When the cylinder is empty close the hose assembly valve and remove the discharge fitting adapter with the reclaim hose assembly.
7. Replace the discharge port cap and the actuation port cap to prevent damage to the threads and lost caps.

1. When this type of cylinder is received, the cutter assembly should have been removed and a shipping cap should have been used. Properly secure the cylinder at the work station so the cylinder will not move it there is an accidental discharge.
   Caution: If the cutter assembly is attached, extreme caution should be used. The cutter tube could be in contact with the seal body assembly and could easily cut through if handled improperly or if the cutter body is rotated improperly. This is extremely important to avoid the possibility of serious injury.
2. Caution: If the cutter assembly is attached, it must be carefully removed by turning it counter clockwise after the cylinder has been properly secured at the work station. The cutter tube should be removed from the cutter assembly. The cutter tube should be cleaned, lubricated, and returned to the cutter assembly so that it is completely in the raised position. If this is not done properly, the cutter could cut through the seal body assembly and cause an immediate discharge.
   If the shipping cap is in place remove it. Securely attach the cutter assembly to the tank assembly by turning it clockwise. Attach the proper discharge fitting adapter with the reclaim hose assembly. Any hose assembly valve should be closed at this time.
3. With the cylinder in the upright position initial discharge will be liquid product (Halon 1301) until the liquid level falls below the bottom of the siphon tube. Additional reclaiming will be vapor and, depending upon the type of reclaiming equipment being used, may require a switch over to a vapor recovery unit. Complete recovery is considered concluded when the reclaiming equipment vacuum gauge shows approximately twenty-five (25) inches of vacuum.
4. To open the valve, pressure must be applied to the elbow fitting on the side of the cutter assembly. Securely attach a hose connected to a nitrogen cylinder and regulator assembly (with output of 800 psi). Rapidly apply nitrogen pressure until the cutter tube is pushed down cutting the seal body assembly. To start the flow of halon, the hose assembly valve should be opened.
5. When the cylinder is empty close the hose assembly valve and remove the discharge fitting adapter with the reclaim hose assembly.
6. Replace the shipping cap if available.
