RECHARGING PROCEDURE

Complete the “Maintenance-Service Procedure”, items 1 thru 10.

2. Discharge all remaining pressure and water (or anti-freeze solution) making sure that there is no

remaining pressure.

3. Remove the valve assembly and disassemble by removing downtube assembly (use a wrench

on the brass retainer, not the plastic tube), spring and valve stem from the valve assembly.
Remove the collar o-ring from the valve assembly.

4. Thoroughly rinse all parts with clean water and wipe dry with a soft cloth. Blow the valve out

with air or nitrogen. Inspect the spring

– replace parts if worn or damaged. Replace valve stem

and collar o-ring. Lubricate the collar o-ring and small o-ring on the valve stem with Visilox V-
711 (do not lubricate the valve stem seal). Inspect the downtube. If it is cracked, deformed or
does not have a threaded brass spring retainer replace the downtube. Inspect downtube o-ring,
replace if necessary.

5. Rinse the cylinder with clean water and inspect the interior following CGA Visual Inspection

Standard, Pamphlet C-6.

6. Firmly replace the plastic fill tube and fill cylinder with clean water until it overflows (2 ½ gallons

[9 ½ liters]).

NOTE: THE AMEREX WARRANTY DOES NOT COVER STAINLESS STEEL
EXTINGUISHERS FILLED WITH WATER WHICH CONTAINS IN EXCESS OF 40 PPM OF
CHLORIDES. IN MANY AREAS WATER INCLUDES HIGH LEVELS OF CHLORIDES.

Install a “Verification of Service” collar around neck of cylinder. Install valve assembly to the
cylinder and properly align. CAUTION: Hand-tighten the valve collar nut to 100-125 in. lbs.
max (1.15

– 1.44 KG/m). Over-tightening with a wrench will damage the valve.

8. Remove cap from the air pressurizing valve on the side of the valve body and pressurize with

100 psi (690 kPa) using air or nitrogen. NOTE: A 02141 fill adapter may also be used by
installing to the female valve outlet (where the hose assembly attaches). The pressure
regulator should be set to no more than 125 psi (862 kPa). Replace pressure valve cap. The
cap must be in place to insure that the valve will not leak.

9. Check the collar, gauge, cylinder welds and valve orifice for leaks using a leak detection fluid or

a solution of soapy water. Remove leak detection fluid from the valve assembly by blowing out
with air and wipe exterior of the extinguisher to dry.

10. Install hose assembly into the operating valve.

11. Install ring pin with ring facing front of the extinguisher. Install new tamper seal. Record

recharge date and attach new recharge tag.

12. Weigh assembled extinguisher and confirm that the total weight is within the allowable

tolerances indicated in the Maintenance section on the extinguisher nameplate.
