MAINTENANCE INSTRUCTIONSHALON 1 / 1,2 / 2,5 AIR TOTALInspection(1) The inspection should be carried out every 2 years, or in shorter intervals, depending oninternal regulations.Inspection:• Integrity of wire seal visual inspection• Condition of extinguisher, mounting bracket and visual inspectionfastening strap• Legibility of label visual inspection• Container pressure / gauge visual inspectionat room temperature the pointer mustbe in the green section of the dial.• Weight control / scalePermissible deviation: 2% of fill capacity / year, but not more than 10% of fill capacity(2) Basic overhaul• Container hydrostatic pressure testAll fire extinguishers listed in these maintenance procedure instruction must behydrostatically pressure tested at regular 10 year intervals (see label on back). Shoulddeficiencies be detected at a regular inspection this pressure test must be performed earlier.These tests shall only be carried out by an authorized aviation equipment inspector, welladverted with the safety standards applicable to this test. Furthermore , also required is anadequate room and the necessary test equipment. After the hydrostatic pressure test thecylinder has to be desiccated inside.The manufacturer recommend to replace the extinguisher after 10 years!ATA 26-24-05 F 74/76-00 dated May 2008Page 6 of 13Subject to change without notice Replaces E 74/76-00 dated January 2005

MAINTENANCE INSTRUCTIONSHALON 1 / 1,2 / 2,5 AIR TOTALDisassembly and cleaning• Empty the extinguisher (observe environmental protection regulations concerning HALON1211).• Unscrew valve (50*, 50A*) with open-end wrench size 17.• Unscrew the siphon tube (220*, 220A*).• Visually inspect valve and container threads and O-ring seat for damage.• Press operation lever and check mobility of valve spindle.• Visually inspect inside of container for corrosion.• Screw siphon tube back up to the limit stop with a torque of 20 Nm.• Screw valve with new O-ring (20*) back on to the container.(Apply a light layer of acid free vaseline to thread and O-ring).Torque: 30 Nm• Clean container. Check label, mounting bracket and fastening strap for damage.* see page 12 fire extinguisher parts listATA 26-24-05 F 74/76-00 dated May 2008Page 7 of 13Subject to change without notice Replaces E 74/76-00 dated January 2005

MAINTENANCE INSTRUCTIONSHALON 1 / 1,2 / 2,5 AIR TOTALFilling (see illustration 2)The fire extinguisher shall only be refilled by a maintenance service shop with an approval to“Commission Regulation (EC) No 1702/2003”.When filling HALON extinguishers the filling station must observe the following instructions:(1) Determining net weight:After assembly the empty extinguisher it must be placed on a scale to determine theweight. This net weight must be entered in the check note.(2) Refilling:Place the extinguisher on a scale and connect it to the fill station. During the filling processthe release lever of the extinguisher must be held down with a clamp. The weight of thisclamp must be taken into consideration in the weighing process.The extinguishing agent is filled according to weight. Care must be taken to observe thepermissible fill tolerances.Portable Fire Extinguishers:HAL 1 1 Kg HALON 1211 (+0 -0.02 kg)HAL 1,21.2 Kg HALON 1211 (+0 -0.02 kg)HAL 2,52.5 Kg HALON 1211 (+0 -0.02 kg)After the filling the extinguisher must be pressurized with gaseous nitrogen (99.0 to 99.8degree of purity, dew point -40°C, (-40°F)). The pressurization for HAL 1, HAL 1,2 andHAL 2,5 should be according to temperature-pressure curves T565*.The nominal fill pressure at +15°C is 11 bar (mark in green section of gauge dial). Thanmove the closed extinguisher horizontally back and forth to mix HALON and nitrogentogether. In this process the container pressure drops. Depressurize the extinguisher tothe specified pressure. Remove the clamp from container release lever. Secure releaselever. The fill line can than be depressurized and also closed.* see page 13ATA 26-24-05 F 74/76-00 dated May 2008Page 8 of 13Subject to change without notice Replaces E 74/76-00 dated January 2005

MAINTENANCE INSTRUCTIONSHALON 1 / 1,2 / 2,5 AIR TOTAL(3) Determination of total weight:After the fill process is completed and the extinguisher disconnected from the fill line, theextinguisher must be placed back on the scale again to determine the total weight. Thisweight must be entered in the inspection record card and on the extinguisher check note(when weighing the extinguisher, the weight of seal, seal wire and the approval label mustbe included).Seal the extinguisher (Seal wire tensile strength 40 N).(4) Acceptance of filled extinguisher:Acceptance and clearance of the extinguisher must be made by authorized staff.Acceptance test:• General visual inspection of the extinguisher• Checking operating pressure (see page 5 technical data)• Tightness control. Checking the unit after 3 weeks in storageIllustration 2Filling StationSchematic arrangementATA 26-24-05 F 74/76-00 dated May 2008Page 9 of 13Subject to change without notice Replaces E 74/76-00 dated January 2005
