AccuFlow™ and AccuFlow HP™ Installation & Operation Manual
Discharging the AccuFlow™ System
The AccuFlow system must be discharged of all anhydrous ammonia and the system must be completely shut
down before the implement can be transported.
The following procedure outlines the proper method for discharging NH
3
from the AccuFlow system and
preparing the system for transport, service, or maintenance.
Note:
Personal protective equipment such as a respirator, protective suit and gloves are required when
working with anhydrous ammonia products.
Before transporting the AccuFlow™ system or beginning service or maintenance:
1.
Toggle the console or vehicle master switch to the off position.
2.
Completely close the main shut-off valve on the supply or nurse tank.
3.
(AccuFlow HP™ only) Turn off boost pump control by turning the respective product off and closing the
tractor SCV (selective control valve).
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.
6.
Completely close the emergency shut-off valve on the AccuFlow super cooler.
7.
Bleed and disconnect the nurse tank supply hose from the AccuFlow system.
8.
Toggle the console master and all section switches to the on position.
9.
While standing upwind from the implement, slowly open bleed valve(s) until fully open. Refer to Figure 1 on
page 12 for assistance locating AccuFlow bleed valve(s).
10.
Allow a minimum of one (1) hour to fully discharge the system.
Verify that the pressure gauge on the
AccuFlow manifold reads zero and the super cooler is not cold to the touch before opening the system. This
ensures that all liquid NH
3
has evaporated and pressure has been discharged.
DANGER
DO NOT transport the AccuFlow system while it
is charged with anhydrous ammonia. The
AccuFlow super cooler and product lines must
be completely discharged before transporting
the implement.
DANGER
Use extreme caution when opening a
previously pressurized system. Exposure to
anhydrous ammonia can cause severe burning,
blindness, or death. To avoid injury or death,
always wear proper personal protective
equipment.
