5. Check the date of manufacture on the extinguisher hanger loop or on the extinguisher
nameplate. Cylinder must be hydrostatically tested every 5 years to the test pressure indicated
on the label.
6. Visually inspect the pressure gauge:
a. If bent, damaged or improper gauge, depressurize and replace
b. If pressure is low, check for leaks
c. If over pressurized (overcharged), depressurize (discharge) and follow recharging
instructions.
7. Inspect the footstand (base). If cracked or broken replace with proper footstand.
8. Inspect ring pin for freedom of movement by breaking the seal and removing the pin. Replace
the ring pin if bent or if removal is difficult.
9. Inspect discharge lever for dirt or corrosion that might impair freedom of movement. Inspect
carrying handle for proper installation. If lever, handle or rivets are damaged or distorted,
replace with proper Amerex part(s).
10. Remove hose assembly, inspect hose assembly for damage, replace as necessary. Blow air
through hose assembly to insure passage is clear of foreign material.
11. Inspect the valve assembly for corrosion or damage to hose thread connections. Replace valve
assembly or component parts as necessary following the proper depressurization and recharge
procedures.
12. Install hose and nozzle assembly.
13. Install new tamper seal and record service data on the extinguisher inspection tag.
14. Rehang the extinguisher on the wall hanger bracket making sure that it fits the hanger bracket
properly
– replace the bracket if necessary.
RECHARGE
RECHARGING is the replacement of the extinguishing agent and includes the expellant for this type of
extinguisher.
THE FIRE EXTINGUISHING AGENT IN THIS EXTINGUISHER MUST BE COMPLETELY REPLACED
EVERY THREE YEARS. Use only the Amerex Model 502 AFFF or Model 504 FFFP concentrate
charge to retain the UL approval and manufacturer’s warranty. Substitute charges could make the
extinguisher less effective.
WARNING:
a. Before attempting to recharge be sure this extinguisher is completely depressurized.
b. Use a regulated nitrogen pressurizing source. Set the regulator no more than 125 psi (862 kPa)
higher than the gauge operating pressure.
c. Check and calibrate regulator gauge at frequent intervals. The regulator gauge should be used
to determine when the intended charging pressure has been reached. Do not use the
extinguisher gauge for this purpose.
d. Never leave an extinguisher connected to a regulator of a high pressure source for an extended
period of time. A defective regulator could cause the cylinder to rupture due to excessive
pressure.
