All fire extinguishers should be installed, inspected and maintained in

accordance with the National Fire Protection Association standard titled

"Portable Fire Extinguishers", NFPA-10 and the requirements of local

authorities having jurisdiction.

When maintenance is indicated it should be performed by trained

persons having proper equipment. Fire extinguishers are pressure

vessels and must be treated with respect and handled with care. They

are mechanical devices and require periodic maintenance to be sure that

they are ready to operate properly and safely. Amerex strongly

recommends that the maintenance of portable fire extinguishers be done

by a trained professional – your local authorized Amerex Distributor.

Amerex Corporation makes original factory parts available to insure

proper maintenance – USE OF SUBSTITUTE PARTS RELEASES

AMEREX OF ITS WARRANTY OBLIGATIONS. Amerex parts have

machined surfaces and threads that are manufactured to exacting

tolerances. O-rings, hoses, nozzles, and all metal parts meet precise

specifications and are subjected to multiple in-house inspections and

tests for acceptability. There are substitute parts available that may be

incorrectly labeled as UL component parts, some are advertised as

Amerex type. None of these meet UL requirements and all of them void

the Amerex extinguisher warranty and UL listing. DO NOT

SUBSTITUTE.

INTRODUCTION THIS MANUAL IS ATTACHED TO EVERY NEW EXTINGUISHER SHIPPED FROM THE FACTORY. IT CONTAINS VALUABLE INFORMATION WHICH SHOULD BE STUDIED BY EVERYONE WHO WILL USE OR SERVICE THE EXTINGUISHER. THE MANUAL SHOULD BE STORED IN A CONVENIENT LOCATION FOR EASY REFERENCE. PREPARING YOUR NEW EXTINGUISHER FOR USE WARNING: THIS FIRE EXTINGUISHER IS SHIPPED FROM THE FACTORY EMPTY. AFTER INITIAL PREPARATIONS, CAREFULLY FOLLOW THE RECHARGING INSTRUCTIONS BEFORE PLACING IT INTO SERVICE. 1.

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 extinguisher 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.

VENTING DEVICE (Standard on all Stationary Extinguishers, Optional on Wheeled Extinguishers) A venting device has been installed on all stationary extinguishers to provide a means of safely and easily relieving residual argon pressure from the agent cylinder while utilizing the same pressure to evacuate or "blow down" the hose. See Below: Figure 1 – Models 484, 485 & 486 (Tall Units – 110 cu. ft. Nitrogen Cylinder) Figure 2 – Models 481, 482 & 483 (Short Units – 23 cu. ft.

AMEREX CORPORATION DOES NOT SERVICE, MAINTAIN OR RECHARGE FIRE EXTINGUISHERS. THIS MANUAL IS PUBLISHED AS A GUIDE TO ASSIST QUALIFIED SERVICE PERSONNEL IN THE INSPECTION, MAINTENANCE AND RECHARGE OF AMEREX FIRE EXTINGUISHERS ONLY. NO INSTRUCTION MANUAL CAN ANTICIPATE ALL POSSIBLE MALFUNCTIONS THAT MAY BE ENCOUNTERED IN THE SERVICE OF FIRE EXTINGUISHERS.

ANNUAL MAINTENANCE – SERVICE PROCEDURE WARNING: BEFORE SERVICING, BE SURE THE EXTINGUISHER AGENT CYLINDER IS NOT PRESSURIZED. THIS PROCEDURE IS BEST ACCOMPLISHED WITH THE EXTINGUISHER IN AN UPRIGHT POSITION AND ON A LEVEL SURFACE. 1. Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the instruction nameplate is securely fastened and legible. Inspect the cylinders for corrosion, abrasion, dents or weld damage.

MAINTENANCE OF REGULATED WHEELED EXTINGUISHERS NOTE: Steps R-a thru R-d apply to models with a Regulator. These procedures should be performed only by professionally trained and qualified service personnel thoroughly familiar with industry service procedures and safety precautions. All extinguisher and service equipment components, fittings and adapters must be in good condition and properly connected. R-a. Disconnect the regulator from the agent cylinder.

e. Operate the nozzle lever to ensure proper operation and to clear the hose of any obstructions (if hose is obstructed – refer to Troubleshooting section of this manual. f. Close the nitrogen pressure source and slowly relieve remaining pressure by fully operating the nozzle lever. 9. Remove the agent cylinder cap and examine it closely for any signs of damage, cracks or thread wear. Clean the agent cylinder fill cap threads and thread vent port on the cap with a stiff bristle nylon brush.

Disconnect the high pressure hose from the argon cylinder valve. Securely install the service kit Argon/Nitrogen Cylinder Pressure Check Gauge Assembly to the nitrogen 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. Close the nitrogen cylinder valve and disconnect the Pressure Check Gauge Assembly. 13.

b. Carefully tip extinguisher over until it rests on both wheels and handle. (In this position much of the agent will remain in the cylinder). c. Open nozzle valve slowly to clear hose of any remaining pressure and chemical (be prepared for a recoil and discharge of agent). d. Insure that all pressure has escaped before further disassembly. e. Stand extinguisher upright after complete depressurization. 2. Complete items 1-6 of Maintenance Procedures. Carefully remove the fill cap.

TROUBLESHOOTING GUIDE WARNING: BEFORE ATTEMPTING TO CORRECT ANY LEAKAGE PROBLEM, BE SURE THAT THE AGENT CYLINDER IS COMPLETELY DEPRESSURIZED. Always use caution when opening the shutoff nozzle or any other connection as a leaking nitrogen cylinder valve seat may have pressurized the agent container refer to the recharge procedure for proper method of depressurization. PROBLEM Nitrogen cylinder reads low or high 1. 2. 3. 4. 5. 6. 7.

Connect hose coupling to outlet on the extinguisher. Lay hose straight on ground to its full 25 ft. length. Start first regular loop counterclockwise by placing between side brackets and over the top bracket. 2 The second loop is a REVERSE loop. Notice that the hose passes behind the loop on this reverse loop. If instructions are followed, the hose will uncoil without kinks. 3 The next loop is a regular "hose in front" loop. Succeeding loops are alternated: reverse, front, reverse, etc.
