DA, DB, MA, MB, HA, HB, SA, SB SeriesHose Reel Service Manual AERO-MOTIVE COMPANYA Woodhead Industries, Inc. SubsidiaryIMPORTANT SAFETY INSTRUCTIONSPlease read this manual carefully and follow its instructions. Improper use or failure to follow these instructions could result in serious injury, death or property damage. Operators should be instructed in the safe and proper use and maintenance of this product. Keep this manual for future reference.The following safety precautions call attention to potentially dangerous conditions.NOTE: Instruct operators in the safe, proper use and maintenance. Keep this manual for future reference. INSTALLATIONMOUNTINGSome reels come complete with hose and are set at proper tension, ready to install. The fixed base ofthe reel allows mounting in several different positions including base up, base down, or wall mounted.Here are general mounting requirements:•Main-shaft must be horizontal.•Centerline of the spool assembly must be in-line with the hose pull out.•When mounted overhead in base up position, add a secondary chain, bracket or other safety device to prevent reel from falling in case the mounting bolts are removed or become loosened fromvibration.SECONDARY SUPPORT CHAINAll reels mounted over head should have a secondary support chain to protect personnel in case ofstructure or mounting component failure. Attach one end of secondary support chain or cable to reel.Attach other end of secondary support chain or cable to a support component other than that whichsupports the reel. The chain or cable should be as short as possible allowing reel to drop no more than 6to 12 inches if the primary connection is released.SUPPLY HOSEAssemble supply hose to main-shaft. Do not use rigid pipe at input connection.Use Teflon tape or pipe sealant to reel hose fitting threads.NOTE: To avoid damage to the swivel, use a wrench to support the swivel fitting while tightening the hose.ADJUSTMENTRATCHET LOCKRatchet lock works with reel mounted in any position and needs no adjustment. Check reel for correctoperation by slowly pulling out the hose. A “clicking” noise will be heard every half revolution of the drum.To latch the reel, pull out the hose and allow it to retract after hearing the first second or third “ click”. Tounlatch, slowly pull out the hose until the “clicking” noise stops, then let the hose retract until the hosestop rests against the hose guide. To disable, ratchet parts must be removed.HOSE GUIDE ARM ADJUSTMENTFor maximum hose life, adjust guide arm so that the hose payout is in line with guide assembly (seeillustration below). To adjust the guide arm, remove screws, and rotate guide arm 90 degrees to nextgroup of mounting holes in stand assembly.TENSION ADJUSTMENTNOTE: Pull hose out completely to insure enough spring revolutions remain for operating. Always leave at least 1-2 turns between full extension and when the spring is wound tight (bottomed out). If entire hoseassembly cannot be pulled out, decrease spring tension until full extension is possible.Reels shipped with hose installed are pre-tensioned at the factory. Reels shipped without hose requirepre-tensioning after hose is installed and before making final hose connections. To pre-tension hosereel, pull hose out far enough to allow one full wrap of hose to be looped back over drum assembly.Hold, drum from turning and loop hose back on drum. Repeat steps above until desired tension isachieved. After tension is set, pull hose out completely to check spring travel. If full hose extension is notpossible, remove pre-tension turns until full hose tension is possible. Failure to test in this manner maycause spring damage. Complete all hose connections.SERVICEHOSE INSTALLATION AND REPLACEMENTRemove all tension from reel (see Tension Adjustment). Remove ball-stop, unwind hose on reel, andunscrew hose from swivel. Feed new hose through roller guide and through slot in flange. Then connecthose to swivel (use Teflon tape or thread sealant), wind onto drum assembly, and re-tension reel.MAINSPRING ASSEMBLY REPLACEMENTNOTE: Mainspring is completely self-contained and safe to handle. If spring is to be replaced when not broken make sure to remove all tension from reel before proceeding.If reel will not develop tension or retract hose,the main-spring will need to be replaced.To replace main-spring:•Remove supply hose to swivel•Remove swivel by loosening its hex end•Remove retaining ring and spacerwashers from main-shaft.•Do not attempt to remove screws fromswivel side of spring pocket. Instead,remove nuts from the stand side of thedrum cavity.•Pull containerized spring pocket assemblyoff drum axle•Reverse procedure to reassemble (useTeflon tape or thread sealant on hoseconnections)•Re-tension reel as in “TensionAdjustment”SWIVEL REPLACEMENTNOTE: Swivel only sold as complete assembly. If o-rings are leaking, complete swivel must be replaced.You may test for leaks using soapy water.To replace swivel:•Turn off or lockout air/fluid supply to reel•Remove all tension from reel (see Tension Adjustment)•Disconnect supply hose to swivel•Remove swivel by loosening its hex end•Disconnect reel hose from swivel•Reverse above procedure and install new swivel (use Teflon tape or thread sealant on connections)REPLACEMENT PARTSNOTE: The DA, DB, MA, MB, HA, HB, SA, and SB reels have common wearing components available as replacement parts. If the part you need is not found on this list, a new reel may be your best alternative.

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 are incorrectly labeled as UL component parts, some are advertised as Amerex type. None of these meet UL requirements and all of them voids the Amerex extinguisher warranty and UL listing. DO NOT SUBSTITUTE.AMEREX CORPORATION – P.O.

Special maintenance and recharge instructions contained in this manual apply to these extinguishers only. Halotron I “Clean Agent” extinguishers are designed for Class A, B, and C hazards formerly protected with Halon 1211 extinguishers. They contain dichlorotrifluoroethane (R-123), which is designated for streaming fire extinguisher applications. Halotron I is listed in the U.S. Environmental Protection Agency (EPA) “Significant New Alternative Policy” (SNAP) as acceptable for nonresidential applications. Halotron I has acceptable toxicity and cardiac sensitization levels for use in occupied spaces when used according to the instructions on the nameplate and rules of the EPA SNAP Program.PHYSICAL PROPERTIES OF HALOTRON IPrimary Component Dichlorotrifluoroethane (R-123) or (HCFC-123)80.6°F [27°C]BoilingPointlb./ft³ (1.48 kg / liter)92.3LiquidDensitylb./ft³ (6.17 kg / m³)0.385GasDensityWeight 150.68MolecularLiquidPhysical State PressurizedVapor Pressure @ 68ºF [20ºC] (liquid alone) 11.2 psi [77 kPa]Pressure of mixture in Container @ 68ºF [20º] 95 psig in bulk containerAMEREX CORPORATION DOES NOT SERVICE, MAINTAIN OR RECHARGE FIRE EXTINGUISHERS.

AMEREX ASSUMES NO LIABILITY FOR SERVICE, MAINTENANCE OR RECHARGE OF FIRE EXTINGUISHERS BY PUBLISHING THIS MANUAL.INSTALLATIONTHIS MANUAL SHOULD BE CAREFULLY STUDIED BY ALL WHO MIGHT USE OR SERVICE THE EXTINGUISHER. STORE IT IN A CONVENIENT PLACE FOR EASY REFERENCE.Your layout and particular hazards dictate the placement of fire extinguishers. NFPA-10 (1-6.9) recommends that hand portable extinguishers with a gross weight less than 40 lbs. be hung with the top of the extinguisher not more than 5 ft. (1.53 m) above the floor. Extinguishers having a gross weight greater than 40 lbs. (18.14 kg) should be installed so that the top of the extinguisher is not more than 3 ½ ft. (1.07 m) above the floor. All extinguishers should be in an accessible location and near an exit. Never install the extinguisher in a location where a potential hazard would prevent easy access.The operational temperature range is -40°F to +120°F (-40°C to +60°C). The extinguisher must be protected if temperatures outside of these ranges are anticipated. Never throw an extinguisher into a fire because rapid heat buildup could cause pressure expansion and exceed the limitations of the cylinder.MOUNTING INSTRUCTIONSYour extinguisher should be mounted in a clean, dry area accessible to the fire hazards and preferably near an exit. Hang it so that the top is from 3½ to 5 feet above the floor and out ofthe reach of small children. Use the mounting bracket furnished with the extinguisher. Fasten to a solid surface using strong screws or fasteners (not included). Follow the Mounting Instructions below.1MOUNTING INSTRUCTIONSU/L specifies that the hanging device must withstand a vertical force of five times the weight of the charged extinguisher but not less than 100 pounds. The extinguisher bracket should be mounted as follows:WALLS WHERE 2 X 4 STUDS CAN BE FOUND Mount wall hanger bracket securely to stud using two No. 10 x 1¼ inch long wood screws through the diagonal smaller holes in the bracket.SHEET ROCK Mount a ¾ inch thick board to wall u sing 3/16 inch toggle bolts. Board should extend a minimum of two inches beyond all sides of the extinguisher profile (excluding hose and wand). Mount hanger racket to board using two No. 10 x 1 inch long wood screws as above.CINDER BLOCK OR CEMENT Mount wall hanger bracket using one ¼ inch toggle bolt or masonry lead screw expansion anchor through center hole in wall bracket.CONCRETE OR TILE WALLS Mount wall hanger bracket using one ¼ inch masonry lead screw expansion anchor through center hole in wall bracket.

DO NOT USE INCONFINED SPACES SMALLER THAN THE MINIMUM STATED ON THEEXTINGUISHER LABEL.1.Remove extinguisher from wall hanger bracket.2.Hold extinguisher upright, twist and pull ring (safety) pin.3.Start back a minimum of 8 feet from the fire. Aim the nozzle at the base of the fire nearestyou.4.Keeping the extinguisher upright, squeeze the lever to discharge. Sweep the agent stream fromside to side.5.Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and smokefrom any fire may be hazardous and can be deadly.WARNING: SYMPTOMS OF OVER-EXPOSURE TO PURE Halotron I MAY CAUSE CENTRAL NERVOUS SYSTEM EFFECTS SUCH AS DIZZINESS, DROWSINESS, ANESTHESIA, OR UNCONSCIOUSNESS. PERSONS SUFFERING FROM OVER-EXPOSURE SHOULD BE IMMEDIATELY REMOVED TO AREA WITH FRESH AIR. APPLY ARTIFICAL RESPIRATION IF NECESSARY. CONTACT A PHYSICIAN.INSPECTIONExtinguishers should be INSPECTED when initially placed in service and at regular intervals (monthly or more often if circumstances dictate) to insure they are ready for use. Inspections may be accomplished manually or, in some cases, by electronic monitoring.2INSPECTION [NFPA-10] 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 changed. Inspections may be accomplished manually, or in some cases by electronic means.PERIODIC INSPECTION PROCEDURES(monthly or more often if circumstances dictate)This extinguisher should be inspected at regular intervals (monthly or more often if circumstances dictate) to insure that it is ready for use.A "quick check" should be made of the extinguisher for the following:1.Location in designated place2.No obstruction to access or visibility3.Operating instructions on nameplate legible and facing outward4.Safety Seals and tamper indicators not broken or missing5.Determine fullness by weighing or "hefting"6.Examination for obvious physical damage, corrosion, leakage, or clogged nozzle7.Pressure gauge reading in the operable rangeMAINTENANCEExtinguishers should be subjected to maintenance at intervals of not more than 1 year, at the time of hydrostatic test, or when specifically indicated by an inspection or by electronic notification. Maintenance procedures include a thorough examination of the basic elements of a fire extinguisher:1.Mechanical parts2.Extinguishing agent of cartridge operated extinguishers, pump tanks and certaintypes of stored pressure extinguishers3.Expelling meansNOTE: Stored pressure Halotron I extinguishers do not require an internalexamination of the cylinder or examination of the agent during annualmaintenance, but shall receive a thorough external examination.Maintenance [NFPA 10] Maintenance is a thorough examination of the fire extinguisher. It is intended to give maximum assurance that a fire extinguisher will operate effectively and safely. It includes a thorough examination for physical damage or condition to prevent its operation and any necessary repair or replacement. It will normally reveal the need for hydrostatic testing.MAINTENANCE/SERVICE PROCEDURE1.Clean extinguisher to remove dirt, grease or foreign material. Check to make sure that the instruction nameplateand UL manifest are securely fastened and legible. Inspect the cylinder for corrosion, abrasion, and dents or weld damage. If any of these conditions are found and you doubt the integrity of the cylinder, hydrostatically test to factory test pressure, using the proof pressure method in accordance with CGA C-1 and NFPA 10.NOTE: When cleaning avoid use of solvents around the pressure gauge. They could seriously damage the plastic gauge face.32.Inspect the extinguisher for damaged, missing or substitute parts. Only factory replacement parts are approvedfor use on Amerex fire extinguishers.3.Weigh extinguisher and compare with weight printed in the Maintenance section on the nameplate. Rechargeextinguisher if weight is not within indicated allowable tolerances.4.Check the date of manufacture on the extinguisher nameplate. Cylinder must be hydrostatically (proof pressure)tested every 12 years to the test pressure indicated on the nameplate. Check the last date complete maintenance was performed. Per NFPA 10 these extinguishers shall be emptied and subject to complete maintenance every six years. All maintenance/service and recharge procedures shall be done at that time.5.Visually inspect the pressure gauge:a.if bent, damaged or improper gauge, depressurize and replace.b.If pressure is low, check for leaksc.if pressure is low or high and temperature/pressure relationship has been ruled out:1.Low pressure – check for leaks. Follow procedure for reclaiming Halotron I agent, install necessarypart(s) to repair leak and recharge according to instructions.2.High pressure (over pressurized or over charged) - depressurize and recharge extinguisher followinginstructions in Recharge section.6.Remove nozzle or hose and nozzle assembly and inspect for damage. Blow air through nozzle or hose and nozzle toinsure that passage is clear of foreign material. Replace component parts with proper Amerex part as necessary.7.Check ring pin for freedom of movement by breaking the seal and removing the pin. Replace the ring pin if bent orif removal is difficult.8.Inspect discharge lever for dirt or corrosion that might impair freedom of movement. Inspect carrying handle forproper installation. If lever, handle or rivets are damaged or distorted, replace with proper Amerex part(s).9.Inspect valve assembly for corrosion or damage to hose thread connection. Replace valve assembly or componentparts as necessary following the proper depressurization and recharge procedures. If valve removal is necessary complete all steps in the Recharge Procedure.10.Install nozzle or hose and nozzle assembly.11.Install new tamper seal and record service data on the extinguisher inspection tag.12.Rehang the extinguisher on the wall hanger bracket making sure that it fits the hanger bracket properly – replacethe bracket if necessary.RECHARGERecharging [NFPA-10]. The replacement of the extinguishing agent and also includes the expellant for this type of extinguisher.WARNINGa. Halotron service should be performed only in a well ventilated room by a properly trained servicetechnician wearing proper eye protection and rubber gloves.b. Before attempting to recharge be sure this extinguisher is completely depressurized by slowly andcarefully depressing the operating lever and discharging the extinguisher into a proper collection area.4c. Use a regulated pressurizing source using ARGON ONLY. Set the regulator to no more than 25 psihigher than the extinguisher gauge operating pressure.d. Check and calibrate regulator gauge at frequent intervals. The regulator gauge should be used todetermine when the intended charging pressure has been reached. DO NOT USE THE EXTINGUISHER GAUGE FOR THIS PURPOSE.e. Never leave an extinguisher connected to a regulator of a high pressure source for an extended periodof time. A defective regulator could cause the cylinder to rupture due to excessive pressure.RECHARGENote: The following procedure is for an EMPTY Halotron I extinguisher. If you are recharging an extinguisher, which has been partially discharged (with agent remaining in the cylinder) or has been recharged and the pressure leaked, follow the instructions contained in the Recharging Instructions packaged with the Amerex Recharge Kit (P/N 14538) or with Getz Halotron recovery equipment.plete items 1 through 9 in Maintenance Service Procedure above.2.Verify that there is no pressure remaining in the extinguisher.3. Remove the valve assembly by turning it counter clockwise. Disassemble by removing downtubeassembly (use a wrench on the downtube retainer, not the tube), spring and valve stem from the valve assembly.4.REMOVE AND DISCARD THE COLLAR O-RING AND VALVE STEM ASSEMBLY. Inspect and cleanthe spring with a clean, dry cloth – replace if worn or damaged. Clean internal valve body surfaces and threads with a soft bristle brush making sure that the valve stem seating area is not scratched. Installa new (green) collar o-ring and valve stem assembly (green seal). Lightly lubricate the collar o-ring andsmall o-ring on the valve stem with Visilox V-711 (do not lubricate the valve stem seal). Inspect the downtube. If it is damaged replace with proper downtube (see Parts List). Install downtube securely.NOTE: Valve assemblies are not indexed. Keep original valve assembly/cylinder combinations together while performing maintenance or recharge to assure proper nameplate orientation.5.Inspect the interior of the cylinder following CGA Visual Inspection Standard, C-6.6.Install the valve assembly to the cylinder in a clockwise direction Install the proper Amerex rechargeadapter and draw a vacuum of 27" of mercury (adjusted for altitude variations – see your vacuum pump manual for detailed instructions). Place the extinguisher on a scale and tare weight prior to filling.7.Connect the extinguisher to a Halotron I supply cylinder using the Amerex P/N 14538 Halotron IRecharge Kit or equivalent.NOTE: The Halotron I supply cylinder MUST be pressurized to approximately 100 psi with ARGON at all times.58.Depress the operating lever and fill extinguisher with the amount of agent specified on the nameplateUSING ONLY CLEAN, UNCONTAMINATED HALOTRON I AGENT. (See detailed instructions on your recharging system).CAUTION: AVOID LIQUID HALOTRON I CONTACT WITH EXTINGUISHER CYLINDER. WIPE DRY IMMEDIATELY WITH A CLEAN CLOTH.9.Pressurize to the extinguisher operating pressure with ARGON only. Repeatedly rock the extinguisherto thoroughly mix the ARGON pressurizing gas until proper pressure is reached. Add additional ARGON as necessary until the pressure stabilizes.10.Check for leaks at the gauge, valve outlet and valve/cylinder connection using a halogen type leakdetector or leak detection fluid. DO NOT USE SOAPY WATER! Thoroughly remove all leak detection fluid residue from the valve assembly and cylinder. Remove recharge adapter.CAUTION: IF YOU USE A HALOGEN TYPE LEAK DETECTOR A RESIDUAL AMOUNT OF HALOTRON I WILL REMAIN IN THE VALVE BODY UNTIL THE LIQUID EVAPORATES. TO PROPERLY LEAK TEST USING THE HALOGEN LEAK DETECTOR IT IS RECOMMENDED THAT THE EXTINGUISHER BE SET ASIDE A MINIMUM OF 24 HOURS AFTER RECHARGING, THEN LEAK TESTING.11.Place nozzle or hose and nozzle on scale with extinguisher. Weigh and confirm that the total weight iswithin the allowable tolerances indicated in the maintenance section of the extinguisher nameplate.12.Install nozzle or hose and nozzle assembly.13.Install ring pin with ring facing front of the extinguisher. Install new tamper seal. Record rechargedate and attached new recharge tag.TROUBLE SHOOTING GUIDEWARNING: DETERMINE THE SOURCE OF A LEAK BEFORE THE EXTINGUISHER IS DEPRESSURIZED. THE EXTINGUISHER MUST BE COMPLETELY DEPRESSURIZED BEFORE ANY ATTEMPT IS MADE TO REMOVE THE VALVE ASSEMBLY AND CORRECT THE LEAKAGE PROBLEM. SEE INSTRUCTIONS PACKAGE WITH THE AMEREX HALOTRON I RECHARGE KIT P/N 14538 OR GETZ HALOTRON RECOVERY SYSTEM FOR THE PROPER METHOD OF DEPRESSURIZING THE EXTINGUISHER TO AVOID UNNECESSARY DISCHARGE AND MINIMUM AGENT LOSS.ACTIONPROBLEM CORRECTIVE1.
