INSTALLATION
WARNING: DO NOT PLACE THIS EXTINGUISHER CLOSE TO A POTENTIAL FIRE
Do not place this extinguisher close to a potential fire hazard. Amerex recommends location no
less than a 50 foot distance from the hazard while leaving an unobstructed access. Avoid placing it
in an extremely hot or cold place. The operational temperature range for this exti ng uish er is -
65°F to +120°F (-54°C to +49°C). The extinguisher should be adequately protected if temperatures
outside of this range are anticipated. Keep the extinguisher clean and free from dirt, ice, chemicals
and any contaminants that may interfere with its proper operation. DO NOT FUNCTIONALLY
TEST THIS FIRE EXTINGUISHER. (Testing or any use may cause the extinguisher to gradually
lose pressure over a period of time and make the extinguisher ineffective.)
OPERATION
NOTE: Persons expected to use this extinguisher should be trained in initiating its
operation and in the proper fire fighting technique. Familiarize all personnel with
this information before an emergency occurs.
1. Move the extinguisher to within approximately 50 feet of the fire site and keep extinguisher
upright. Remove ring (safety) pin and pull "T" handle to open argon cylinder valve. This will
pressurize the extinguisher.
2. Remove nozzle from the mount, and with the nozzle lever in the closed position, pull hose from
rack.
3. Start back 20 feet from the fire and aim at base of fire nearest you.
4. Open hose and nozzle firmly and be prepared for discharge recoil. Open nozzle by pulling the
handle fully toward you. Slowly sweep side to side across the base of the fire and past both
edges. Progressively follow up until the fire is extinguished.
DISCHARGE TIME (APPROXIMATE) - See extinguisher nameplate (label)
EFFECTIVE RANGE OF THE AGENT THROW - 25 to 40 feet
HOSE LENGTH – 50 feet
RECHARGE FIRE EXTINGUISHERS IMMEDIATELY AFTER ANY USE
SHUTDOWN
1. After making sure that the fire has been completely extinguished, close the nozzle valve and
then close nitrogen cylinder valve (push “T” handle to closed position). Wheeled Extinguisher
– Tip over until it rests on both wheels and handle (in this position much of the remaining
chemical will stay in the cylinder). Stationary Extinguisher – see instructions below.
2. Open the nozzle valve slowly to clear the hose of any remaining pressure and chemical (be
prepared for recoil and discharge of agent).
WARNING: MAKE SURE THAT ALL PRESSURE HAS ESCAPED BEFORE ANY FURTHER
DISASSEMBLY.
3. Stand unit upright after complete depressurization.
NOTE: Nitrogen pressure in the agent cylinder cannot escape through a disconnected nitrogen
hose assembly due to a check valve in the system. Always be careful when removing
the fill cap.
4. Coil the extinguisher hose onto the storage rack and position the nozzle onto the mount in
preparation for transport to the recharge location.
CAUTION: DO NOT TRANSPORT A NITROGEN CYLINDER WITHOUT INSTALLING THE
PROTECTIVE SHIPPING CAP.
