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.
WARNING
Do not use this extinguisher on Class C fires involving energized
electrical equipment, Class D fires or any flammables that will react
with water. Protect from freezing unless charged with an Amerex
Model 506 Loaded Stream/Anti-freeze Charge.
