CHAPTER 6
62 AccuFlow™ Vortex and AccuFlow™ HP+ Installation and Operation Manual
BEFORE TRANSPORTING THE ACCUFLOW SYSTEM OR BEGINNING SERVICE OR MAINTENANCE:
1. Toggle the console or vehicle master switch to the off position.
2. (AccuFlow HP+ only) Turn off boost pump control by closing the tractor SCV (Selective Control Valve).
3. Completely close the main shut-off valve Figure 1 on page 63 (Item 1) on the supply or nurse tank. Also close
the shut-off valve at the nurse tank bulkhead if so equipped.
NOTE: Never run the pump without product in the application lines as damage to the pump seals will result.
4. Resume field application until the pressure gauge reads no remaining pressure is in the AccuFlow system.
5. Verify that the console and/or vehicle master switch, and all section switches, are in the off position. Ensure the
tow vehicle is upwind (as shown in Figure 1 on page 63) of the toolbar implement.
6. Completely close the emergency shut-off valve (Item 3) either by using the rope from the cab of the tractor, or
the handle on the valve itself on the AccuFlow Vortex cooler.
7. Bleed and disconnect the nurse tank supply hose (Item 2) from the nurse tank.
8. While standing upwind from the implement, with wind direction as show in Figure 1 on page 63, slowly open
the AccuFlow system primary bleed valve (Item 4), until it is fully open. Ammonia will discharge out the vapor
knives on the toolbar.
9. Always bleed system slowly when time permits by leaving valves open slightly over an extended period of time.
10. Remain at the primary bleed valve (Item 4) and adjust or close as necessary until ammonia cloud is no longer
coming out of the vapor knives. After ammonia cloud has dispersed, check the pressure and temperature
gauges (Item 6) to verify that the pressure reads zero, and all parts are at ambient temperature (no frost).
11. Open secondary bleed valve (Item 5) slowly to relieve any remaining liquid ammonia from the system.
12. Re-verify that the pressure gauge on the AccuFlow manifold reads zero and all AccuFlow components are not
cold to the touch before opening the system.
