8. START-UP <br /> If all instructions thus far have been followed, the system should start itself and run <br /> automatically. Proceed with the following steps: <br /> 8.1 Check to see that nozzles are on their hangers and vapor hoses are <br /> connected. Check also to see that gasoline storage tank fittings (fill caps, <br /> dry breaks, drop tubes, drain valves, etc.) are seated and sealing. <br /> 8.2 At the Indicator Panel, turn the POWER switch ON. The green lamp on the <br /> switch should light, and the processor should have electrical power now. <br /> The green PROCESSING lamp will be lit intermittently (only when the <br /> processor is energized), and the red OVERPRESSURE lamp should remain <br /> extinguished. <br /> WARNING: The processor (pilot and main burner) is automatic. It will cycle its <br /> thermal oxidizer ON if vacuum diminishes in the vapor spaces and <br /> OFF if there is sufficient vacuum. Therefore use caution when <br /> working close to the thermal oxidizer. It may come ON without <br /> notice. A mirror is recommended for looking down the stack. <br /> 8.3 Check the pressure in storage tanks. <br /> 8.3.1 If UST ullage pressure is negative (vacuum), then proceed with step <br /> 8.6. <br /> 8.3.2 If the storage tank pressure is positive, check to see that turbine is <br /> running and either there is a flame at pilot burner tip or a spark. If <br /> not, reset thermal switch inside processor's electrical panel, by <br /> depressing (red) pushbutton, see FIGURE 7, Field Wiring Drawing. <br /> Turbine and spark should come on. If so, proceed with step 8.4. If <br /> turbine is not running or sparking is not present, refer to Hirt VCS <br /> 100 Troubleshooting Manual. <br /> 8.4 Within 1 hour, the processor pilot and main burner stages should ignite. <br /> Once a vacuum of approximately -0.40" w.c. is generated, the processor <br /> should shutoff. This indicates that the processor is completely functional <br /> and controlling itself automatically. If so, go to step 8.8. If the stages don't <br /> ignite within 1 hour or if your work schedule is such that waiting 1 hour is <br /> inconvenient then continue with the following step 8.5. <br /> Page 14-13 <br /> ARB Approved IOM-14—Hirt VCS 100 Processor Installation Manual—Executive Order VR-205-B <br />
