OWNER’S SERVICE MANUAL INSTALLATION, OPERATING & SERVICING INSTRUCTIONS MANUAL PN 05605 125/150 LB. NITROGEN CYLINDER DRY CHEMICAL EXTINGUISHERS MODELS 450,451,452,467,468,469,470,471,472 All fire extinguishers shall be installed, inspected, and maintained in accordance with the National Fire Protection Association standard titled "Portable Fire Extinguishers", NFPA 10, or the National Fire Code of Canada and the requirements of local authorities having jurisdiction.

INTRODUCTION THIS MANUAL IS ATTACHED TO EVERY NEW EXTINGUISHER SHIPPED FROM THE FACTORY. IT CONTAINS VALUABLE INFORMATION WHICH SHALL BE STUDIED BY EVERYONE WHO WILL USE OR SERVICE THE EXTINGUISHER. THE MANUAL SHALL BE STORED IN A CONVENIENT LOCATION FOR EASY REFERENCE. PREPARING YOUR NEW WHEELED EXTINGUISHER FOR USE 1. Remove all shipping straps, and wrappings from unit. Remove attached manual, and review for proper installation and use of your extinguisher.
PAGE 4
OPERATION NOTE: Persons expected to use this extinguisher shall 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 pull pin and pull “T” handle to open nitrogen cylinder valve. This will pressurize the extinguisher. 2.

INSPECTING THE EXTINGUISHER NFPA 10 - This extinguisher must 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.

3. Check the date of manufacture printed on the extinguisher label (nameplate) or on the agent cylinder dome. The agent cylinder, discharge hose assembly, and nitrogen supply hose must be hydrostatically tested every 12 years. Test pressure: a. Agent Cylinder – 500 psi (3447 kPa) b. Hose Assembly – 300 psi (2068 kPa) c. Nitrogen Supply hose assembly - 3000 psi (20,684 kPa) 4. Check the hydrostatic test date on the crown of the nitrogen cylinder.

WARNING: IF THE PRESSURE READING EXCEEDS THE GIVEN PARAMETERS, QUICKLY CLOSE THE NITROGEN CYLINDER “T” HANDLE OR HANDWHEEL VALVE AND VENT THE PRESSURE BY OPENING THE FLOW CHAMBER BALL VALVE. REGULATORS CANNOT BE FIELD ADJUSTED – THEY MUST BE REPLACED IF FOUND TO BE OUT OF TOLERANCE. R-c.

b. Using a regulated nitrogen pressure source, set to the extinguisher operating pressure, slowly and briefly pressurize the agent cylinder (the siphon tube shall 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 nitrogen hose connects) will indicate a defective gas tube and will require that the agent cylinder be emptied and the gas tube replaced. c.

NOTE: Proper procedure for recharging any dry chemical extinguisher includes the use of a closed recovery system (NFPA 10). Getz Equipment offers several systems ideal for this application that provide for the recovery of the remaining agent by direct discharge into the system, trapping the “fines” while allowing the nitrogen to escape and provides a more accurate fill of the extinguisher. IF A “CLOSED-RECOVERY SYSTEM” IS NOT AVAILABLE PROCEED AS FOLLOWS: 1. To depressurize: a.

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 cylinder. Refer to the recharge procedure for proper method of depressurization.

Guide to Proper Installation of Hose on Wheeled Fire Extinguishers 1 Connect hose coupling to outlet on the extinguisher. Lay hose straight on ground to its full 50-foot. (15.24 m) length. Start first regular loop counter-clockwise 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.
