ARB Approved IOM—Healy ase II EVR System—VR-201-A(7513 Serie ose) Page 23 <br /> Healy Model 75B Series Inverted Coaxial Hoses <br /> 1.0 Healy Model No. 75B Series Coaxial Hose <br /> Healy 75B Series Hoses and Hose Assemblies should be serviced by a Healy Certified <br /> Technician. Hoses should be inspected for kinks, flat spots, abraded outer cover (wire <br /> strands visible) and leaking fittings on a weekly basis. <br /> Note: The following procedures shall be conducted after installation or repair, <br /> with the dispenser authorized and ready to dispense fuel. <br /> 1.1 Field Serviceable Hose Components <br /> 1.1.1 Healy Part No. HB-2 O-ring (Item 1, in Figure below). This o-ring seals the fitting <br /> to the nozzle and the adapter. Liquid gasoline visible on the hose indicates a <br /> damaged or improperly installed HB-2 o-ring. Replace the o-ring, if necessary. <br /> 1.1.2 Healy Part No. HB-4 Quad Seals (Item 2, in Figure below). These quad seals <br /> are used on the end of the hose that attaches to the breakaway assembly (or <br /> flow limiter, if equipped). If the symptom is meter creep (gallons dispensed <br /> display on dispenser is counting up when the nozzle is not dispensing gasoline), <br /> check the HB-4 quad seals at the breakaway (or flow limiter, if equipped) end of <br /> the hose for cuts or damage. Replace the seals, if necessary. <br /> 1.1.3 Healy Part No. 291 O-ring (Item 3, in Figure below). These o-ring seals are used <br /> on the end of the hose that attaches to the nozzle or hose adaptor assembly. If <br /> the symptom is meter creep (gallons dispensed display on dispenser is counting <br /> up when the nozzle is not dispensing gasoline), check the 291 o-rings at the <br /> nozzle or adaptor end of the hose for cuts or damage. Replace the seals, if <br /> necessary. <br /> Lubricate any o-ring or Quad Seal before installing the hose assembly into an adaptor, <br /> breakaway or nozzle assembly to make it easier to install and prevent the seal from <br /> getting cut. Motor oil (any weight) is acceptable for lubricating an o-ring or Quad Seal. <br /> Rule of Thumb: O-rings to Nozzle and Hose Adaptor <br /> Quad Seals to Breakaway(or Flow Limiter) <br /> 2 3 <br /> Healy Systems, Inc.
