NOTE: Every effort shall be made to halt unnecessary escape of Halon 1211 to the atmosphere to
prevent detrimental environmental effect. High-efficiency Halon 1211 Recovery/Recharge
Vacuum Pump Type Systems (UL Standard 2006) are commercially available. The Getz Fire
Equipment HR-1L or other UL Approved Recharge/Recovery system assures a minimum of 99%
recovery efficiency. It allows a means of checking for and removing moisture or contamination
during the recovery process.
3. When the extinguisher is empty of all agent and pressure, remove valve assembly and disassemble by
removing downtube, spring, and valve stem assembly. Discard valve stem assembly and collar O-ring.
NOTE: Keep cylinder opening covered while devalved to minimize interior corrosion.
4. Thoroughly clean all parts of the disassembled valve with a soft bristle brush or soft cloth. Blow the valve
out with dry nitrogen.
5. Install a new Amerex valve stem assembly after lightly lubricating the valve stem O-ring with V-711 (do
not lubricate the valve stem seal). Reassemble the spring and downtube. Carefully install a new collar
O-ring, which has been lightly lubricated with V-711. Set the valve assembly aside.
6. Inspect the cylinder interior following CGA Visual Inspection Standard C-6 and current NFPA 10
guidelines. If a hydrotest has been performed or any moisture is evident, the cylinder shall be immediately
warm-air dried.
7. Clean the O-ring seating groove in the cylinder neck. If any rust is evident, remove by using a fine emery
cloth (200 grit). Clean the surface, and lubricate the entire sealing area with a thin film of V-711. Install the
valve assembly in extinguisher cylinder. Hand tighten firmly.
8. Use the Getz HR-1L or other UL Approved Recharge/Recovery system to purge the residual air from the
extinguisher cylinder.
9. Stand the extinguisher upright on a scale of sufficient size and capacity. Tare weight extinguisher, or
record empty weight.
10. Follow all recharging instructions on Getz HR-1L or other UL Approved Recharge/Recovery system.
11. Remove the recharge adapter. Some residual Halon vapor may remain in the valve outlet as a result of
the charging procedure. Before attempting to leak detect, vacuum or blow the vapor away from the areas
to be checked. Check extinguisher for leaks at the valve outlet, around the collar seal, cylinder welds, and
gauge using a Halogen Leak Detector (Preferred Method). The alternate method is to apply leak detecting
fluid or a solution of soapy water to these areas. Use dry nitrogen to blow all liquid residue out of the valve
and wipe the extinguisher to dry the exterior. DO NOT LEAVE ANY LIQUID INSIDE THE VALVE BODY.
12. Install pull pin, new tamper seal, nozzle, or hose and horn assembly to the extinguisher discharge valve.
13. Weigh extinguisher to confirm that the total weight is within the tolerances indicated in the Maintenance
section on the extinguisher nameplate.
14. Record service date, and attach new tag in accordance with the requirements of the "Authority Having
Jurisdiction".
