PREPARING YOUR NEW EXTINGUISHER FOR USE
1. Remove all wrappings, straps, and pallet retaining bolts.
2. Examine the extinguisher for shipping damage.
3. Remove shipping cap(s) from CO2 cylinder(s). Install discharge hose (50 lb.) or manifold (100 lb.) to
cylinder valve(s). Check to insure that the hose connection to the opening valve/or manifold and hose to
the squeeze-grip shut-off valve are tight.
4. Check to insure that the cylinder valve(s) are in the CLOSED position. The pull pin(s) shall be installed
and the tamper seal(s) intact.
5. Visually inspect the safety relief on the cylinder valve for evidence of obstruction or damage. DO NOT
REMOVE.
6. This extinguisher is shipped from the factory fully charged. The most accurate method to determine if the
extinguisher is filled with the proper amount of Carbon Dioxide is to weigh the unit. The gross weight is
indicated on the lower right hand corner of the pictogram operation ‘INSTRUCTIONS’ (plus weight of
cylinders stamped on the cylinder valve[s]).
7. Record the date the unit is being placed into service on the inspection tag, and attach it to the
extinguisher.
INSTALLATION
Your plant layout and particular hazards dictate the placement of fire extinguishers. Do not place this
extinguisher close to a potential fire hazard. Amerex recommends location no less than a 20-foot distance
from a potential hazard while leaving an unobstructed access. Avoid placing it in an extremely hot or cold
place. The operational temperature range for this extinguisher is -22ºF to +120ºF (-30ºC to +49ºC). The
extinguisher shall be adequately protected if temperatures outside of this range are anticipated. Keep the
extinguisher clean and free from dirt, ice, chemicals, and any contaminants which may interfere with its
proper operation. Do not functionally test this fire extinguisher. (Testing or any use may cause the
extinguisher to gradually lose pressure and become ineffective.)
OPERATION
NOTE: Persons expected to use this extinguisher shall be trained in initiating its operation and in
the proper fire-fighting technique. Familiarize all personnel with this information before an
emergency occurs.
WARNING: HIGH CONCENTRATIONS OF CARBON DIOXIDE CAN CAUSE RESPIRATORY
PROBLEMS. SELF CONTAINED BREATHING APPARATUS OR AIR LINE
RESPIRATORS SHALL BE USED IF OXYGEN LEVER HAS BEEN DIMINISHED BELOW
19%. AVOID SKIN CONTACT – CO2 IS VERY COLD AND COULD CAUSE BURNS OR
FROSTBITE.
1. Move the extinguisher (wheeled unit) to within 30 feet of the fire site.
2. Twist and pull the pull pin(s) snapping the tamper seal(s). Pull “T”-handle cylinder valve lever(s) to open
cylinder valve. Pull hose from rack. Start back 10 feet from the fire.
3. Grasp horn squeeze-grip shut off valve, and aim horn at base of fire nearest you.
4. Squeeze horn shut off valve lever. 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.
5. When the fire is out release the horn shut off valve lever to stop discharge. Stand by and watch for
possible reignition.
