WARNINGS
USE THIS EXTINGUISHER ONLY ON CLASS D BURNING METALS. CLASS D
FIRES NORMALLY GENERATE EXTREMELY HIGH HEAT. AMEREX
RECOMMENDS THE USE OF PROTECTIVE CLOTHING AND SELF-CONTAINED
BREATHING APPARATUS WHILE OPERATING THIS EXTINGUISHER.
TO AVOID RE-IGNITION AFTER A METAL FIRE HAS BEEN EXTINGUISHED, DO
NOT MOVE THE REMAINS UNTIL THE METAL HAS COOLED.
SODIUM CHLORIDE BASED POWDER CAN BE VERY CORROSIVE,
ESPECIALLY ON METALS. AFTER THE FIRE HAS BEEN EXTINGUISHED AND
REMAINS HAVE COOLED, CLEAN ALL SURFACES CONTACTED BY THE DRY
POWDER.
NEVER USE WATER ON A COMBUSTIBLE METAL FIRE. CHEMICAL AND
PRESSURIZING GAS MUST BE MOISTURE FREE.
THIS EXTINGUISHER SHOULD BE PRESSURIZED WITH DRY ARGON ONLY.
PREPARING YOUR NEW EXTINGUISHER FOR USE
THIS MANUAL IS PACKAGED WITH EVERY NEW EXTINGUISHER SHIPPED FROM THE FACTORY. IT
CONTAINS VALUABLE INFORMATION WHICH SHOULD BE STUDIED BY EVERYONE WHO WILL USE OR
SERVICE THE EXTINGUISHER. THE MANUAL SHOULD BE STORED IN A CONVENIENT LOCATION FOR
EASY REFERENCE.
1. Remove the Model 570/B570 and its discharge hose assembly from the shipping carton. Examine both for
shipping damage.
2. Connect the wand assembly to the extinguisher hose male connector by retracing the locking sleeve on the
wand female swivel coupling. Push the female coupling firmly onto the male swivel adapter and release the
locking sleeve. Tug firmly on the wand to verify that the swivel coupling is completely engaged.
3. Arrange the discharge hose and extension applicator assembly in the retaining clips as shown in the
installation diagrams on page 9.
4. Install your extinguisher in an accessible location with the top of the handle no more than 3½ feet (1 m) above
the floor, the base at least 4 inches (.1 m) above the floor and near a doorway. DO NOT INSTALL IT
WHERE YOU WOULD HAVE TO WALK THROUGH A POTENTIAL FIRE LOCATION TO REACH IT!
5. Do not place this extinguisher close to a potential fire hazard. Amerex recommends a location no less than
50 feet (15 m) from the hazard, leaving unobstructed access. Avoid placing it in an extremely hot or cold
place. The operational temperature range is –40°F to +120°F (40°C to +49°C). Adequately protect the
extinguisher if temperatures outside this range are anticipated. Keep the extinguisher clean and free from
dirt, ice, chemicals and any contaminants that may interfere with its proper operation. DO NOT
FUNCTIONALLY TEST THIS FIRE EXTINGUISHER – testing or any use may cause it to gradually lose
pressure and become ineffective. Never throw any extinguisher in a fire as it could explode from
heat/pressure buildup.
NOTE: Slight pressure variances in the gauge reading may be found if the extinguisher has been
subjected to extremes of heat or cold. High temperatures can cause high gauge readings and low
temperatures, low readings. When in doubt condition the extinguisher to 70°F (21°C) for several hours to
obtain a more accurate pressure gauge reading.
6. Record the date the extinguisher is being placed into service on the inspection tag and attach it to the
extinguisher.
