2. (AccuFlow HP+) Turn off boost pump control by closing the tractor SCV (selective control valve).
NOTE: Verify that the pressure gauge readings on both the AccuFlow system and the nurse tank(s) are
matching before closing any valves between the nurse tank(s) and AccuFlow system. If the pressure
gauge readings do not match, the gauges may be defective and should be replaced as soon as
possible.
3. Completely close the main shut-off valve 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 normal field application until the pressure gauge reads no remaining pressure is left in the AccuFlow
system.
5. Toggle the control console or vehicle master switch to the off position and verify that all section switches are in
the off position.
6. Ensure that the tow vehicle is upwind of the NH
3
toolbar and application system.

DANGER
Pressure gauges can fail, become plugged, or
display incorrect pressure. Liquid NH
3
can absorb
heat from surroundings and re-pressurize the
system. Any bleed valves that are opened to
relieve pressure should remain open while
transporting the system or maintenance is being
performed. Treat every section where NH
3
can be
trapped as though it is pressurized.
