INSTALLATION, OPERATING & SERVICING INSTRUCTIONS

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

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.

CAUTION: USE OF DRY CHEMICAL AGENT EXTINGUISHERS ON FIRES ON DELICATE ELECTRONIC EQUIPMENT IS NOT RECOMMENDED. IT MAY SUCCESSFULLY EXTINGUISH THE FIRE BUT MAY DAMAGE THE EQUIPMENT BEYOND REPAIR. (Consult your Amerex Distributor for more details.) Discharge Time (approx.): Effective Range of the agent throw is: Hose Length: 60 - 70 seconds 30 - 40 feet 50 feet RECHARGE FIRE EXTINGUISHERS IMMEDIATELY AFTER ANY USE SHUTDOWN 1.

. Check the gauge on the nitrogen cylinder. If the pressure is below 1700 psig (11.7 mPa) repressurize the cylinder to 2015 psig (13.9 mPa) or replace it. A low gauge pressure may indicate leakage. Check for leaks. A low gauge reading may also result from low temperature. See the temperature/pressure relationship chart in the Troubleshooting Guide. Check the tamper indicator (lockwire seal) on the nitrogen valve and replace if necessary. 6.

d. AFTER ALL PRESSURE HAS BEEN RELIEVED, SLOWLY OPEN THE FILL CAP AND REMOVE THE TEST KIT VENT SPACER. e. Re-examine the dry chemical agent to determine if any obstructions were cleared from the siphon tube and have risen to the liquid surface. f. Clean the fill cap and agent cylinder thread surfaces. Install the fill cap gasket and securely install fill cap. Disconnect the high pressure hose from the nitrogen cylinder valve.

2. Complete items 1 – 6 of Maintenance Procedures. Carefully remove the fill cap. While performing this procedure, all parts and seals should be cleaned, inspected and replaced where necessary. 3. Remove shutoff nozzle assembly from discharge hose and clean thoroughly. Check to make sure that the valve is closed when the lever is in the forward position (toward the nozzle tip). 4.

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.. 1. 2. 3. 4. 5. 6. 7. PROBLEM Nitrogen cylinder gauge reads low or high Nitrogen pressure is too low. Valve is closed.

1 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. for six full loops. Guide to Proper Installation of Hose on Wheeled or Stationary Fire Extinguishers Connect hose coupling to outlet on the extinguisher. Lay hose straight on ground to its full 50 ft. length.
