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 Corp. 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 which 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
which are incorrectly labeled as U/L component parts, some are advertised as Amerex type. None of these meet U/L requirements and all of them void
the Amerex extinguisher warranty and U/L listing. DO NOT SUBSTITUTE.
