WARNING: DO NOT USE THESE EXTINGUISHERS ON FIRES

INVOLVING ENERGIZED ELECTRICAL EQUIPMENT (CLASS C

HAZARDS), FLAMMABLE METALS (CLASS D HAZARDS) OR ANY

FLAMMABLE THAT WILL REACT WITH WATER. PROTECT FROM

FREEZING!

All fire extinguishers should be installed, inspected and maintained in

accordance with the National Fire Protection Association standard

titled "Portable Fire Extinguishers", NFPA-10 and the requirements of

local authorities having jurisdiction.

When maintenance is indicated it should be performed by trained

persons having proper equipment. Fire extinguishers are pressure

vessels and must be treated with respect and handled with care. They

are mechanical devices and require periodic maintenance to be sure

that they are ready to operate properly and safely. Amerex strongly

recommends that the maintenance of portable fire extinguishers be

done by a trained professional – your local authorized Amerex

Distributor.

Amerex Corporation makes original factory parts available to insure

proper maintenance – use of substitute parts releases Amerex of its

warranty obligations. Amerex parts have machined surfaces and

threads that are manufactured to exacting tolerances. O-rings, hoses,

nozzles, horns and all metal parts meet precise specifications and are

subjected to multiple in-house inspections and tests for acceptability.

There are substitute parts available that are incorrectly labeled as UL

component parts, some are advertised as Amerex type. None of these

meet UL requirements and all of them void the Amerex extinguisher

warranty and UL listing. DO NOT SUBSTITUTE.

RECHARGE FIRE EXTINGUISHERS IMMEDIATELY AFTER ANY USE
