3. Reassemble the valve assembly, including downtube and set aside.
4. Remove any chemical remaining in the cylinder and check the condition. Properly dispose
of any chemical that is contaminated or caked.
5. Inspect the cylinder interior following CGA Visual Inspection Standard C-6.
6. Using an accurate scale, fill cylinder with the correct amount and type of dry chemical
specified on the label (nameplate). Use Amerex chemical which has been kept free of
moisture and contamination. See Warning (g)
– DO NOT MIX TYPES OF CHEMICALS.
7. Clean cylinder collar o-ring seat and collar threads with a small brush and then wipe off
surfaces with a clean cloth to remove dust. Lightly brush the collar o-ring seat with Visilox
V-711.
8. Install "verification of service" external collar tag. Install discharge valve assembly and
attach pressurizing adapter (P/N 06160) to discharge port.
9. With the extinguisher properly secured in an upright position, connect your nitrogen
pressurizing line with a quick connect to the nitrogen charging adapter. Rotate the
extinguisher operating valve lever to the open position and pressurize extinguisher with dry
nitrogen to 240 psi. When the desired pressure has been reached, rotate the operating
lever to the closed position. Shut off nitrogen supply and remove the quick connect.
CAUTION: Pressurizing the extinguisher in this manner will allow for proper
aeration of the chemical through the downtube. Do not use the
"bleeder" valve to pressurize the extinguisher.
10. Check extinguisher for leaks by applying detecting fluid or a solution of soapy water to the
nitrogen charging adapter orifice, around the collar o-ring sealing area, cylinder welds and
gauge. Remove the pressurizing adapter.
11. Reconnect the hose to the operating valve. Properly coil the hose on the rack and install the
nozzle (with the lever in a closed position) on the mount.
NOTE: When assembling the hose to the agent cylinder or nozzle to the hose, tighten
the coupling ¼ turn after contacting the hose gasket.
12. Install ring (safety) pin and lockwire (tamper) seal. Record recharge date and attach new
recharge tag.
13. Weigh assembled extinguisher and confirm that the total weight is within the allowable
tolerances indicated in the Maintenance section of the nameplate (label).
14. Return extinguisher to its proper location. Mountings for stationary extinguishers should be
properly secured.
