Examine the dry powder agent for proper type and condition. Replace chemical that is contaminated,

caked or other than the type indicated on the nameplate (label). Do not trust the height of the chemical in
the cylinder when determining agent fill. Dry powder settles and the only true indication of agent fill is to
weigh the extinguisher and compare with the weight indicated on the nameplate (label).
Place the service kit Vent Spacer on top of the agent cylinder fill opening collar. Check again to see that
8.
the fill cap thread vent is clean and that the agent fill cap gasket is in place. Install the agent fill cap
securely over the vent spacer.
CUIDADO: (PASO 15) The agent cylinder cap threads must be clear and the cap securely installed
onto the vent spacer and agent cylinder to allow pressure to slowly vent after performing the
siphon tube clearing and gas tube integrity checks.
To perform a siphon tube clearing and gas tube integrity check:
9.
a. Remove the service kit Agent Hose Adapter from the discharge hose assembly and install it
securely onto the agent cylinder siphon tube outlet.
b. Using a regulated argon pressure source set to the extinguisher operating pressure (110 psi),
slowly and briefly pressurize the agent cylinder (the siphon tube should be clear within a
couple of seconds and the agent cylinder pressure slowly vent from the fill cap thread
vent). Pressure and/or dry chemical agent leaks from the gas tube inlet port (where the hose
connects) will indicate a defective gas tube and will require that the agent cylinder be emptied
and the gas tube replaced.
c. Close the argon pressure source and allow all pressure to slowly vent from the thread vent port
on the fill cap.
d. AFTER ALL PRESSURE HAS BEEN RELIEVED, SLOWLY OPEN THE FILL CAP AND
REMOVE THE TEST KIT VENT SPACER.
e. Re-examine the agent to determine if any obstructions were cleared from the siphon tube and
have risen to the surface.
f.
Clean the fill cap and agent cylinder thread surfaces. Securely install the fill cap gasket and fill
cap.
Disconnect the service kit quick connector adapter from the low pressure port of the regulator and
10.
reinstall the regulator securely to the agent cylinder.
Disconnect the high pressure hose from the argon cylinder valve.
11.
Argon/Nitrogen Cylinder Pressure Check Gauge Assembly to the argon cylinder valve outlet and verify
the indicated cylinder gauge pressure. Argon pressure should conform to the temperature correction
chart provided in the Troubleshooting section of this manual.
disconnect the Pressure Check Gauge Assembly.
ADVERTENCIA:
OR A HANDWHEEL QUICK OPENING TRIP RELEASE, THE SAFETY VENT PLUG SHIPPED WITH
THE EXTINGUISHER, OR THE TEST KIT SAFETY VENT PLUG MUST BE INSTALLED TO PROTECT
SERVICE PERSONNEL FROM A HIGH VELOCITY DISCHARGE IN CASE THE LEVER IS
ACCIDENTALLY OPENED.
Install a new Amerex Moisture Seal per instructions in the package. Securely connect the discharge hose
12.
to the extinguisher. When assembling the hose to the agent cylinder or nozzle to the hose, tighten
the coupling ¼ turn after contacting the hose gasket.
Coil the hose on to the extinguisher hose rack using the Reverse Loop Procedure (see instructions in this
13.
manual). Install shut-off nozzle (and/or extension wand) with the lever in the Closed (forward) position
into the nozzle mount.
Remove the safety vent plug from the argon cylinder. Reconnect the high pressure hose securely to the
14.
argon cylinder valve. Wipe the extinguisher clean. Record service data on the inspection tag according
to NFPA-10 requirements and attach to extinguisher. Return extinguisher to its proper location.
