Systems Scheduled Maintenance <br /> 1. Assist Phase II EVR System <br /> Scheduled Maintenance Instructions for an Assist Phase II EVR System with VP1000 Vacuum <br /> Source and 900 Series EVR Nozzle. <br /> Initial problems are usually caused by installation irregularities that are easily detected and <br /> repaired by performing the "VP1000 Vacuum Performance Test Procedure" located in the <br /> dispenser installation manual. Periodic maintenance described here will eliminate problems and <br /> maintain peak operation of the system. <br /> NOTE: Only a Certified Technician can service any problems discovered while conducting <br /> the Weekly or Quarterly Inspection and Testing. Provided that there are no other <br /> local district requirements, a GDF Owner/ Operator can remove and install nozzles, <br /> curb hoses, breakaways, flow limiters and whip hoses without a manufacturer <br /> certification. Additional certifications may be required in accordance with local <br /> district requirements. <br /> 1.1. Weekly Inspection and Testing <br /> 1 .1.1. Inspect each nozzle, hose, and breakaway for damage, loose connections, or leaks. <br /> Inspect nozzles for damaged vapor boots or spouts. Any nozzle with a vapor <br /> collection boot which is missing, or which has one half of the mini-boot faceplate or <br /> greater missing should be replaced or repaired as soon as practicable. Spouts with <br /> visible damage must be replaced. <br /> Inspect hoses for wear, severe kinks, cracks, and splitting. Replace if wire braid is <br /> visible. <br /> 1.1.2. Test the VP1000 Vacuum Pump for normal operation using the following test <br /> procedure: <br /> Normal operation will have the VP1000 Vacuum Pump running at low speed if <br /> only one side of a dispenser/ pump is activated (ready to dispense fuel) and will <br /> run at full speed if both sides of the dispenser are activated (ready to dispense <br /> fuel). The VP1000 vacuum pump may continue to run for a few seconds after a <br /> nozzle is re-holstered. <br /> NOTE: If any of the four bullets below cannot be achieved, tag out dispenser and call <br /> a Healy Certified Technician for service. <br /> ■ The VP1000 vacuum pump should come on immediately when a nozzle is <br /> lifted and the dispenser is activated and ready to dispense fuel. <br /> ■ Repeat for each nozzle on both sides of the dispenser being tested, oneat <br /> a time, to verify the VP1000 vacuum pump is running after the dispenser <br /> is activated and ready to dispense fuel. <br /> NOTE: For unihose dispensers, conduct individual tests for each product <br /> grade on each side of the dispenser to ensure that the VP1000 <br /> activates for all grades on the same side. <br /> 1-1 <br /> CARB Approved IOM 1 —Systems Scheduled Maintenance—EO's VR-201 and VR-202 <br />
