ACCUFLOW™ VORTEX SYSTEM (NON-PUMP) CALIBRATION AND OPERATION
11. Inspect the system for leaks.
a. If leaks are detected, close the nurse tank shut-off valve and proceed to step 12.
b. If no leaks are detected, skip to step 13.
12. If leaks are present:
a. Close the nurse tank shut-off valve.
b. Open the bleed valve(s) and allow all NH
3
in the lines to evaporate and discharge from the system. When
the system is fully discharged, all components should not feel cold and the pressure gauge reading on the
AccuFlow system should be at zero.
c. After the system is completely discharged, disconnect the nurse tank hose.
d. Correct leaks and repeat step 9 through step 11.
13. Verify that pressure gauge readings on the AccuFlow system and the nurse tank are matching. If the pressure
readings do not match, one of the gauges may be defective and should be replaced.
14. Fully open the nurse tank shut-off valve. The AccuFlow system is now charged and ready for operation.
VERIFYING ACCUFLOW™ OPERATION
Once the AccuFlow system is charged, the system is ready for the application of anhydrous ammonia to the
field(s). The following items should be checked periodically to ensure proper operation of the AccuFlow system
and application of anhydrous ammonia:
1. Verify that the implement/boom widths, speed cal, meter cal, valve cal, and rate cals have been programmed
correctly on the console (refer to the control console’s Operation manual for details).
2. Toggle the master switch to the off position.
3. Toggle the console to manual control mode.
4. Toggle the switch for section 1 (boom 1) on. If a multi-manifold system is in use, toggle all sections on. Toggle
any section switches not in use to their off positions.
5. With the master switch in the off position, drive at the target application speed to verify the speed readout on
the console.
6. With applicator knives in the ground, toggle the master switch to the on position.
7. While driving at the target application speed, manually adjust the flow with the INC/DEC switch until the target
rate is achieved.
8. Toggle the console to automatic mode. In automatic mode, the console will adjust the control valve
automatically to maintain the target rate regardless of vehicle speed. If the console is not capable of
maintaining the target rate, refer Chapter 7, Troubleshooting .
NOTE: Due to the highly corrosive nature of many additives and nitrogen stabilizers, Raven recommends
injection of the additive after the Vortex cooler, control valve, and vapor lines. This will help prevent
corrosion of heat exchangers and other plumbing components. Corroded materials can cause system
components such as strainers, flowmeters, and orifices to become obstructed, and can decrease
service interval time and component life expectancy.
DANGER
Use extreme caution when opening a previously
pressurized anhydrous ammonia system.
Exposure to anhydrous ammonia can cause
severe burning, blindness, or death. Always wear
proper personal protective equipment when
working with anhydrous ammonia products.
