AccuFlow™ and AccuFlow HP™ Installation & Operation Manual
AccuFlow HP™ Vapor and Applicator Line
Installation
The following steps will step through the final system connections for the AccuFlow super cooler and NH
3
plumbing.
Note:
Schedule 80 pipe and fittings should be used to plumb any high pressure NH
3
system.
Control valves used with liquid systems
cannot
be used with the NH
3
. Specially designed control
valve(s) must be used with the AccuFlow system to control application of NH
3
.This special NH
3
control valve can be used with all other chemicals; i.e. herbicides, insecticides, and liquid fertilizer.
To complete installation of the AccuFlow HP system:
1.
For best system performance:
a.
Use dual nurse tanks with independent high pressure hose rated for anhydrous use between the nurse
tank and AccuFlow emergency shut-off valves. These hoses should be as short a and breakaways to
the AccuFlow HP assembly or a 2” minimum shared supply line.
b.
Use a high pressure hose rated for anhydrous use between the nurse tank and AccuFlow emergency
shut-off valve. This hose should be as short as possible and must be no longer than 15 feet [4.5 m]
c.
Install a high flow break-away coupler to connect the nurse tank and the AccuFlow intake port. A high
flow tank valve is also recommended.
d.
Use nurse tanks with high flow withdrawal valves and 1-1/2” drop tubes.
e.
Keep supply lines as short as possible and less than 15 ft. [4.5 m].
f.
Do not use street elbows to avoid excessive pressure drops.
Note:
The ON/OFF valve will not be used if a fast control valve is installed.
2.
Verify that all of the applicator hoses are of equal length from each manifold hose barb to each liquid
applicator tube.
3.
Verify that all of the orifice openings in the liquid applicator tubes are unplugged and have the same
diameter.
4.
Connect the hose barb fittings to the vapor ports on the cooler in either configuration shown below.
DANGER
Anhydrous ammonia in vapor form can cause
serious injury or death. Pipe joints must be
properly sealed with RectorSeal™, or an
equivalent thread sealant, to prevent leaks.
