TROUBLESHOOTING GUIDE
WARNING: ANY HALON 1211 EXTINGUISHER MUST BE COMPLETELY DEPRESSURIZED BEFORE
ANY ATTEMPT IS MADE TO REMOVE THE VALVE AND CORRECT A LEAKAGE
PROBLEM.
To depressurize, see instructions in the Complete Maintenance section. Halon 1211 is a liquid under nitrogen
pressure. Variations in the temperature may affect gauge readings. The gauge dial has been calibrated to
reflect the tested extinguisher temperature extremes (-65°F to +120°F). When in doubt about a gauge
reading, place the extinguisher at room temperature (70°F) for several hours to obtain a true reading.
PROBLEM CORRECTIVE ACTION
1. Leak at collar O-ring Remove valve assembly, remove and discard O-ring,
clean collar thoroughly. Install new collar O-ring. Lubri-
cate O-ring with V-711.
2. Leak through valve Check valve stem seating area for scratches or foreign
matter. Clean seating area with a tooth brush and soft
cloth. Install new valve stem assembly.
3. Leak around gauge Remove gauge*, clean threads, and reinstall using Tef-
lon tape on the gauge threads.
4. Defective gauge Remove defective gauge*, and install a new Halon 1211
gauge using Teflon tape on the gauge threads.
5. Leak in the cylinder Contact Amerex if under warranty, otherwise mark
"REJECTED" and remove from service or return to
owner.
6. Leak under operating lever
during discharge
Replace valve stem assembly.
7. Gauge indicator high or low
in green operable area, no
detectable leakage
Extinguisher may have been subjected to extreme heat
or cold. Condition the extinguisher to room temperature
(70°F) overnight and check gauge reading.
* Pressure gauge threads are coated with a special epoxy at the factory. For easy
removal, soak the valve assembly in hot water (180°F) for two to four minutes. Remove
gauge with a thin 7/16" open-end wrench.
