VENTING DEVICE
(Standard on all Stationary Extinguishes, Optional on Wheeled Extinguishers)
A venting device has been installed on all stationary extinguishers to provide a means of safely and easily
relieving residual nitrogen pressure from the agent cylinder while utilizing the same pressure to evacuate or "blow
down" the hose.
INSPECTING THE EXTINGUISHER
This extinguisher should be inspected at regular intervals (monthly or more often if circumstances
dictate) to insure that it is ready for use. Inspection is a "quick check" that a fire extinguisher is available
and is in operating condition. It is intended to give reasonable assurance that the fire extinguisher is fully
charged. This is done by verifying that it is in its designated place, that it has not been actuated or
tampered with, and that there is no obvious physical damage or condition to prevent its operation.
THE FFFP FOAM CHARGE IN THIS EXTINGUISHER MUST BE REPLACED EVERY THREE YEARS PER
NFPA 10. USE ONLY THE AMEREX MODEL 534 CHARGE. USE OF ANY OTHER AGENTS OR
SUBSTITUTES WILL VOID THE UL LISTING AND AMEREX WARRANTY. SEE THE RECHARGE SECTION
OF THIS MANUAL FOR THE APPROPRIATE EMPTYING AND RECHARGING INSTRUCTIONS.

position.

CLOSED position)
3. Remove ring pin and CLOSE agent cylinder valve
(Valve A in Fig. 1) to prevent further chemical from
entering the hose.
4. Remove ring pin and OPEN pressure vent valve
(Valve B in Fig. 1) to allow nitrogen gas to by-pass
the chemical and pressurize the hose.
5. Open discharge nozzle to vent all residual chemical
and nitrogen gas pressure.
6. Re-open nitrogen valve if additional pressure is
required.
7. When recharging this unit, reset agent cylinder and
vent valves, install ring pins and lockwire seals.
