INTRODUCTION
Amerex Wheeled Halon 1211 fire extinguishers provide "clean agent" fire-fighting capability far exceeding that
achievable with hand-portable types. Models 695 (50 lb.) and 600 (150 lb.) are stored-pressure wheeled
Halon 1211 liquefied gas extinguishers. Highly effective on Class-A (ordinary combustibles), Class-B
(flammable liquids) and non-conductive in Class-C (energized electric) hazards. Model 600 may be towed at
speeds up to 15 mph over paved surfaces and can be easily managed by one person.
To provide optimum extinguisher reliability, recharging shall be performed by persons trained in fire
extinguisher maintenance and servicing. This manual shall be used as a guide for installing and servicing
these Amerex extinguishers. The best place to have your extinguishers serviced and recharged is your
Authorized Amerex Distributor who has the professional experience and equipment to do it properly.
PREPARING YOUR NEW EXTINGUISHER FOR USE
1. Remove all wrappings, straps, and pallet retaining bolts.
2. Examine the extinguisher for shipping damage.
3. Check to insure that the hose connection at the discharge valve and the nozzle connection to the hose
are tight.
4. Check to insure that the shutoff nozzle is in the closed position. The pull pin shall be installed and the
tamper seal intact.
5. Visually inspect the pressure gauge. The pressure gauge shall be in the green zone (200 ±10 psi range).
the method used to determine proper agent fill is by weighing the extinguisher and comparing to weight
recorded when initially installed or when previously recharged.
NOTE: Halon 1211 is a liquefied gas that generates its own vapor pressure. Temperature can affect
the pressure gauge reading. Normal "properly charged" markings are correct for 70°F (21°
C.) Generally, as temperatures go up, pressure readings go up. Conversely, lower
temperatures result in lower readings. The relative pressure gauge vs. temperature reading
for Amerex 50 and 150 lb. Halon 1211 wheeled extinguishers is as follows:
Temperature °F -40 32 70 120
Temperature °C -40 0 21 49
Pressure Gauge (psi) 127 168 200 263
When in doubt, condition the extinguisher to 70°F (21°C) for several hours to obtain
accurate indications.
6. Record the date and weight of the unit when placed into service on the inspection tag, and attach it to the
extinguisher.
OPERATION
WARNING: HIGH CONCENTRATIONS OF HALON 1211 CAN CAUSE RESPIRATORY
PROBLEMS. CONCENTRATIONS GREATER THAN 2% BY VOLUME SHALL BE
AVOIDED.
CAUTION: PERSONS EXPECTED TO USE THIS EXTINGUISHER SHALL BE TRAINED IN
INITIATING ITS OPERATION AND IN THE PROPER FIRE-FIGHTING TECHNIQUE.
"DRY-RUN" AND VISUAL-AID TRAINING WILL PREPARE PERSONNEL WITH
THE FEEL FOR THIS EXTINGUISHER SO THAT THE MOST EFFECTIVE
APPLICATION CAN BE UTILIZED IN AN EMERGENCY. THE BASIC OPERATING
INSTRUCTIONS ARE CONTAINED ON THE PICTOGRAM OF EVERY
EXTINGUISHER. THE FOLLOWING ELABORATES ON THESE INSTRUCTIONS:

PN 05606 04/2020
1. Move the extinguisher to within approximately 30 feet (9 m) for 50 lb., 40 feet (12 m) for 150 lb. of the
fire site. Keep the extinguisher upright.
NOTE: The model 600 extinguisher may be operated in either the vertical or reclined position;
however, it will discharge more agent in the vertical position. The model 695 MUST be
operated in the UPRIGHT position.
2. Twist and pull the pull pin. Open cylinder discharge valve by rotating (pulling) the valve lever toward
the hose 90°. The hose is now pressurized with chemical.
3. Pull discharge nozzle, with lever in the closed position, from the mount and extend the hose from the
storage rack.
4. Stand back 15 feet (4 m) to 30 feet (10 m) from the fire, and aim the nozzle at the base of flames
nearest you. Open nozzle by pulling handle toward you (be prepared for a discharge recoil by holding
the nozzle firmly).
5. Sweep side to side across the base of the fire and past both edges. Progressively follow up until the
fire is extinguished. Work the fire away from you while being alert for flashbacks. Move closer as the
fire is extinguished but not so close as to scatter or splash the burning materials.
6. When the fire is out, push the nozzle lever forward to the closed position.
7. Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and smoke from
any fire may be hazardous and can be deadly.
WARNING: SYMPTOMS OF OVER-EXPOSSURE TO PURE HALON ARE DIZZINESS, IMPAIRED
COORDINATION, AND REDUCED MENTAL ACUITY. PERSONS SUFFERING FROM
OVER-EXPOSURE SHALL BE IMMEDIATELY REMOVED TO FRESH AIR. IF
UNCONSCIOUS, GIVE RESPIRATION AND OBTAIN MEDICAL AID. USE OF
ADRENALIN OR SIMILAR DRUGS SHALL BE AVOIDED.
SHUTDOWN
CAUTION: BEFORE PERFORMING THE SHUTDOWN PROCEDURE AND PREPARING
TO MOVE THE EXTINGUISHER TO THE RECHARGE LOCATION,
DETERMINATION MUST BE MADE THAT THE FIRE IS COMPLETELY
EXTINGUISHED AND THERE IS NO DANGER OF A FLASHBACK.
1. Rotate cylinder discharge valve lever 90° to the closed position. Install pull pin to prevent accidental
actuation while transporting to recharge location.
2. Remove residual agent from hose.
CAUTION: Do not leave Halon 1211 in the hose as over-pressurization and deterioration
of the hose may occur.
3. Return the extinguisher to the upright position.
4. Coil the hose onto the storage rack, and position the nozzle into the mount in preparation for
transport to the recharge location.

PN 05606 04/2020
INSPECTING THE EXTINGUISHER
This extinguisher must be inspected at regular intervals (monthly or more often if circumstances
dictate) to insure that it is ready for use. Inspection is a "quick check" that a fire extinguisher is
available and is in operating condition. It is intended to give reasonable assurance that the fire
extinguisher is fully charged. This is done by verifying that it is in its designated place, that it has not
been actuated or tampered with, and that there is no obvious physical damage or condition to prevent
its operation.
PERIODIC INSPECTION PROCEDURES
(Monthly or more often if circumstances dictate)
NFPA 10 Periodic inspection of fire extinguishers shall include a check of at least the following items:
1. Located in designated place.
2. No obstruction to access or visibility.
3. Pressure gauge reading or indicator in the operable range or position.
4. Operating instructions on nameplate and facing outward.
5. Tamper seal not broken or missing.
6. Examination for obvious physical damage, corrosion, leakage, or clogged nozzle.
7. Determine fullness by weighing.
8. Hose properly coiled and shut-off nozzle in its mount.
9. Wheels rotate freely.
MAINTENANCE
NFPA 10 Maintenance is a "thorough check" of the extinguisher. It is intended to give maximum
assurance that a fire extinguisher will operate effectively and safely. It includes a thorough
examination for physical damage or condition to prevent its operation and any necessary repair or
replacement. It will normally reveal if hydrostatic testing or internal maintenance is required.
MAINTENANCE PROCEDURE
1. Clean extinguisher to remove dirt, grease, or foreign material. Check to make sure that the instruction
pictogram is securely fastened and legible. Inspect the cylinder for corrosion, abrasion, dents, or weld
damage. If any damage is found and you doubt the integrity of the cylinder, hydrostatically test to factory
test pressure, using the proof-pressure method, in accordance with instructions in CGA pamphlet C-1 and
C-6 and NFPA 10. See proper method of depressurizing and reclaiming Halon 1211 in Complete
Maintenance procedures.
NOTE: WHEN CLEANING, AVOID USE OF SOLVENTS AROUND THE PRESSURE GAUGE.
THEY COULD SERIOUSLY DAMAGE THE PLASTIC GAUGE FACE.
2. Inspect the extinguisher for damaged, missing, or substitute parts. Only factory replacement parts are
approved for use on Amerex fire extinguishers.
3. Weigh the extinguisher, and compare with weight printed in the "Weight Block" section on the nameplate
(label). Recharge extinguisher if weight is not within indicated allowable tolerances.
4. Check the date of manufacture printed on the extinguisher label (nameplate) or on the agent cylinder
dome. The agent cylinder must be hydrostatically (proof-pressure) tested every 12 years to the test
pressure indicated on the nameplate (will vary according to size). Model 695, 50 lb. (480 psi); Model 600,
150 lb. (500 psi). Discharge hoses must also be hydrostatically tested (proof pressure) every 12 years to
300 psi, or service pressure, whichever is higher.
5. Visually inspect the pressure gauge:
a. If bent, damaged, or improper gauge, depressurize and replace.
b. If pressure is low, check for leaks.
c. If over pressurized (overcharged), depressurize the extinguisher and follow recharge instructions.

PN 05606 04/2020
6. If the Model 600 is so equipped, check the agent lever indicator. The indicator arrow shall be in the Green
zone. Refer to the Trouble Shooting guide if there are any problems with the indicator.
7. Check pull pin for freedom of movement. Replace if bent or if removal appears difficult.
WARNING: ALWAYS OPEN THE SHUTOFF NOZZLE HANDLE SLOWLY. ANY EVIDENCE OF AGENT
IN THE NOZZLE INDICATES THAT THE UNIT MAY HAVE BEEN USED AND THE USE
NOT REPORTED. BE PREPARED FOR A POSSIBLE DISCHARGE AND NOZZLE
RECOIL.
8. Check the nozzle shutoff lever for freedom of movement (open and close several times). If the operation
is impeded, disassemble the nozzle, replace parts, and/or properly lubricate as necessary. Make sure that
the nozzle tip is clear and unobstructed.
9. After making sure that there is no residual pressure in the discharge hose, disconnect it from the
operating valve. Blow air through the hose and nozzle assemblies to insure that the passage is clear of
foreign material. Check the couplings, hose and hose gasket for damage or deterioration – replace as
necessary.
10. Inspect the valve assembly for corrosion or damage to hose thread connection. Visually inspect the safety
disc assembly on the Model 600 discharge valve. Replace valve assembly or component parts as
necessary following the proper depressurization and recharge procedures. If valve removal is necessary,
complete all steps in the Recharge Procedure.
11. Reconnect the hose to the agent cylinder. Properly coil the hose on the rack and install the nozzle (with
the lever in a closed position) on the mount.
NOTE: When assembling the hose to the agent cylinder or nozzle to the hose, tighten the
coupling ¼ turn after contacting the hose gasket.
12. Inspect the wheels on to insure they rotate freely. Lubricate as required.
13. Check carriage assembly for loose nuts, bolts, frame distortion or damage. Check welds for damage or
corrosion. Replace damaged parts or make repairs as necessary.
14. Install new tamper seal, and record service data on the extinguisher inspection tag.
15. If the extinguisher has been moved to perform service, make sure that it is returned to its proper location.
COMPLETE MAINTENANCE (SIX-YEAR MAINTENANCE)
NFPA10 Every 6 years, stored pressure extinguishers shall be emptied and subjected to the
applicable maintenance procedures. When the applicable maintenance procedures are performed
during periodic recharging the six-year requirement shall begin from that date.
WARNING:
a. Before attempting to de-valve the extinguisher for Maintenance, Hydrotest or
Recharging be sure that it is completely depressurized. Halon 1211 generates a
vapor pressure of 22 psi at 70°F. NEVER VENT TO THE ATMOSPHERE. Recover
agent and vapor according to the instructions below.
b. Never have any part of your body over the extinguisher while removing the valve
assembly.
c. Halon 1211 shall not be mixed with even the slightest amount of moisture. Prolonged
exposure of a de-valved cylinder to ambient air shall be avoided to prevent moisture
contamination and cylinder rusting.
COMPLETE MAINTENANCE (SIX-YEAR MAINTENANCE) PROCEDURES
1. Complete steps 1-9 in Maintenance Procedure above.

PN 05606 04/2020
2. Attach the appropriate recharge adapter to the extinguisher operating valve on the extinguisher cylinder.
Empty the extinguisher of all pressure and Halon 1211 using a listed Halon Recharge/Recovery system
and a bulk Halon supply cylinder with sufficient empty capacity to accept the contents of the extinguisher.
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 Recharge/Recovery
(vacuum pump type) systems (UL Standard 2006) are commercially available. The Getz
HR-1 (UL Approved) unit 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 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.
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 or
equivalent (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 or equivalent. Set the valve assembly
aside.
6. Inspect the cylinder interior following CGA Visual Inspection Standard C-6. 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 or
equivalent. Install the valve assembly in extinguisher cylinder. Hand tighten firmly.
8. Use the Getz HR-1 system to purge the residual air from the extinguisher cylinder.
RECHARGE
NFPA 10 is the replacement of the extinguishing agent (also includes the expellant for this type of
extinguisher.
WARNING:
a. Use a protective shield between you and the pressure gauge while charging an
extinguisher. Do not stand in front of the gauge if a shield is not available.
b. Use a regulated pressurizing source of dry nitrogen only with a minimum dew point of -
70ºF (-57ºC). Set the regulator to no more than 25 psi above the extinguisher operating
pressure.
c. Check and calibrate regulator gauge at frequent intervals. The regulator gauge shall be
used to determine when the intended charging pressure has been reached. Do not use
the extinguisher gauge for this purpose.
d. Never leave an extinguisher connected to a regulator of a high-pressure source for an
extended period of time. A defective regulator could cause the cylinder to rupture due to
excessive pressure.
RECHARGING PROCEDURE
1. Perform steps 1-8 of the "Complete Maintenance (Six-Year Teardown)" section.
CAUTION: ALL EXTINGUISHER AND CHARGING SYSTEM VALVES MUST BE CLOSED BEFORE
STARTING THIS PROCEDURE.
2. Thoroughly clean all parts of the disassembled valve with a soft bristle brush or soft cloth. Blow the valve
out with air or nitrogen. Inspect the collar O-ring, valve stem, spring, and downtube assembly, and replace
parts if worn or damaged. Lubricate the collar O-ring and small O-ring on the valve stem with V-711 (do
not lubricate the valve stem seal).

PN 05606 04/2020
2. Follow all recharging instructions on Getz HR-1 or other "approved" Recharge/Recovery System.
3. Fill extinguisher with amount of halon 1211 specified on nameplate and pressurize to the pressure
specified with dry nitrogen.
4. Remove the recharge adapter. Some residual halon vapor may remain in the valve orifice 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 orifice, around the collar seal, cylinder welds and
gauge using a Portable 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.
5. Install hose assembly, with shut-off nozzle attached, to the extinguisher discharge valve. Tighten hose
coupling ¼ turn after contact with hose gasket. Coil hose onto the hose rack and nozzle into mount.
6. Weigh extinguisher to confirm that the total weight is within the tolerances indicated in the Maintenance
section of the extinguisher label (nameplate).
7. Record recharge date, and attach new recharge tag in accordance with the requirements of the "Authority
Having Jurisdiction".
TROUBLESHOOTING GUIDE
WARNING: Before attempting to correct any leakage problem, be sure that the agent cylinder and
hose are completely depressurized. Check to determine the source of a leak before the
extinguisher is depressurized. Leakage repairs will require depressurization and
removal of the valve assembly. Use Getz HR-1 or other approved recharge/recovery
system to depressurize extinguisher.
PROBLEM CORRECTIVE ACTION
1. Pressure gauge reads high or
low
Temperature may have affected pressure – see temperature/
pressure relationship chart.
2. Leak through valve Remove valve assembly, downtube, spring, and valve stem
assembly. Install new valve stem assembly. Check valve seat
for scratches or foreign matter.
3. Leak at collar O-ring Remove valve assembly, clean collar O-ring seating surface
thoroughly and lubricate lightly with V-711 or equivalent. Install a
new collar O-ring after lubricating with V-711 or equivalent.
4. Leak around gauge threads Remove gauge*, and install a new Halon 1211 gauge (see parts
list) using Teflon tape on the gauge threads.
5. Defective gauge Remove defective gauge* and install a new Halon 1211 gauge
(see parts list) using Teflon tape on the gauge threads.
6. Visible deterioration of discharge
hose
Replace hose assembly. Extinguishing agent has been stored in
hose for a prolonged time. see Caution in Shut-Down
procedures
MODEL 600 ONLY
1. Leak at safety disc assembly Inspect safety outlet for tightness or damage. If loose, remove
entire assembly and reinstall using Teflon tape on the threads. If
damaged, replace with new PN 03787 Safety Disc Assembly
using Teflon tape on the threads. Tighten only the large hex nut.
2. Agent level gauge not
functioning (if so equipped)
Remove agent level gauge and discard. Replace agent level
gauge with Amerex PN 06370
* Pressure gauge threads are coated with a special epoxy at the factory. For easy removal, soak
the valve assembly in hot water (180°F/82°C) for two to four minutes. Remove gauge with a 7/16"
open end wrench.
