EPA EHS (Extremely Hazardous Substance):
Despite the common odor, anhydrous ammonia properties are
dramatically different from those of household ammonia
cleaning solutions (dilute ammonium hydroxide).
An uncontrolled release of NH3anhydrous ammonia can easily
be fatal or cause permanent disabling injury.
If you are new to NH3 operations, study everything you can
about this chemical and how to use it safely.
Suffocation, Blinding, Burning, Freezing, Disabling and
Disfigurement Hazards:
Your life and health,
the lives and health of your workers and community,
the continued commercial availability of anhydrous ammonia,
and continuation of agricultural NH3 transport exceptions
depend on you conducting meticulously careful operations.
Read All Manuals
The Anhydrous Safety manual (407-551M), this manual,
the meter manual and the breakaway coupler manual
(FVC062) are required reading for safe operations. All
operators of this equipment must read these manuals.
Even if you are an experienced anhydrous ammonia
operator, read the “Using Anhydrous Ammonia Safely”
manual (407-551M).
The diamond icons and decal image above appear in this
manual whenever a topic deals with anhydrous ammonia
safety. See the “Using Anhydrous Ammonia Safely”
manual (407-551M) for details on these signs. These
topics do not apply to NP3000 models configured only
for conventional liquid fertilizer.

Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone. Know the reporting
requirement for spills or releases of the chemicals you are
using. Have contact numbers available.
▲ For anhydrous ammonia operations, have additional
contact information for:
• national response center
• regional (state) response center
• local response center
▲ If a fire threatens an anhydrous ammonia tank, evacuate the
area. The tank may heat up faster than the relief valve can
vent the rising pressure, resulting in a catastrophic gas
release and possibly an explosion.
407-613M Table of Contents Index 2014-04-22
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals”onpage9,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.
Wear Protective Equipment (PPE)
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ Waterproof, wide-brimmed hat
▲ Face shield, goggles or full face respirator.
▲ Prolonged exposure to loud noise can cause hearing
impairment or loss. Wear suitable hearing protection such
as earmuffs or earplugs.
▲ Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
▲ See manual 407-551M for specific requirements and
recommendations for NH
▲ Goggles with side shields or a full face respirator are
required if handling or applying dusts, wettable powders, or
granules or if being exposed to spray mist.
▲ Cartridge-type respirator approved for pesticide vapors
unless conventional liquid fertilize label specifies another
type of respirator.
▲ Waterproof, unlined gloves. Neoprene is recommended.
▲ Cloth coveralls/outer clothing changed daily; waterproof
items if there is a chance of becoming wet with spray.
▲ Waterproof apron
▲ Waterproof boots or foot coverings
▲ Do not wear contaminated clothing. Wash protective
clothing and equipment with soap and water after each use.
Personal clothing must be laundered separately from
household articles.
▲ Clothing contaminated with certain pesticides must be
destroyed according to state and local regulations. Read
chemical label for specific instructions.

4 NP3000 and NP3000A Table of Contents Index Great Plains Manufacturing, Inc.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This fertilizer applicator requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure before disconnecting
hydraulic lines.
▲ Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ If an accident occurs, seek immediate medical attention
from a physician familiar with this type of injury.
Minimize Radiation Exposure
The optional DICKEY-john® RVS II and RVS III Radars
are intentional radiators of RF energy. Although its
radiated energy level is far below the limits set by
EN 61010-1:1993 A2:1995-Chapter 12.4, it is advisable
not to look directly into the face of the unit.
The radar must radiate toward the ground and at least
20 cm (8 inches) away from a human during use to
comply with the RF human exposure limits as called out
in FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR
USE THE RADAR IN A MANNER INCONSISTENT
WITH ITS DEFINED USE.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can create
a hazard when driven on public roads. They are difficult
to see, especially at night.
▲ Use flashing warning lights and turn signals whenever
driving on public roads.
▲ Use lights and devices provided with implement.
407-613M Table of Contents Index 2014-04-22
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 5
Tires Not a Step
Do not use gauge wheel or lift-assist tires as steps. A tire
could spin underfoot, resulting in a fall onto the applicator
or ground, possibly causing serious injury.
▲ The gauge wheel tires can be in poor ground contact at any
time, even with the fertilizer applicator lowered in the field.
They can appear to be in ground contact, and spin easily, in
multiple conditions.
▲ The lift-assist tires can be in poor ground contact, or out of
ground contact, whenever the fertilizer applicator is
lowered.
Remain Clear of Overhead Lines
▲ If the fertilizer applicator contacts a power line, lethal
voltage may be present on all metal parts. At higher voltage,
the applicator does not need to be in line contact for the
hazard to exist. Maintain at least 10 foot (3 m) clearance.
▲ Electrocution can occur without direct contact between the
energized fertilizer applicator and a person near the
fertilizer applicator.
▲ Watch for sagging, damaged or low electrical lines. The
folded fertilizer applicator could contact lines lower than
13 feet 2 inches (4 m). Overhead lines at farm structures
are a particular hazard.
▲ Watch for all electrical lines during folding and unfolding
operations. Use a spotter during folding and unfolding.
Know the location and height of all lines during transport
and in fields.
▲ If an electrical hazard is observed while on the ground near
the applicator, hop at least 100 feet (30 m) away with both
feet together and summon professional help. At higher
voltage, lethal voltage gradients can also be present at the
soil surface.
▲ Consult your tractor manual for advice on how to respond
to an electrical hazard event while in the cab.

6 NP3000 and NP3000A Table of Contents Index Great Plains Manufacturing, Inc.
Transport Machinery Safely
Maximum transport speed for applicator is 20 mph (32
kph), 13 mph (22 kph) in turns. Some rough terrains
require a slower speed. Sudden braking can cause a
towed load to swerve and upset.
▲ Do not transport an applicator that weighs over 20,000
pounds (9060 kg). Loading liquid fertilizer tanks or
transporting with a nurse tank hitch to the applicator can
easily exceed this limit.
▲ Tow nurse tank separately. Do not tow a nurse tank in train
with the applicator on public roads.
▲ Never park an anhydrous ammonia tank on public roads or
anywhere near sites with high occupancy or high-risk
populations, such as shopping areas, events, schools,
hospitals, retirement communities, etc.
▲ Avoid transporting an anhydrous ammonia tank through
populated areas.
▲ Do not tow a lift-assisted 2-point applicator or nurse tank
that, when fully loaded, weighs more than 1.5 times the
weight of towing vehicle.
▲ Do not transport a 2-point applicator that exceeds the
capacity or ballasting of the tractor. There may not be
enough front wheel traction for safe steering.
▲ Carry reflectors or flags to mark fertilizer applicator in
case of breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 142.
▲ Do not exceed 20 mph (32 km/h). Never travel at a speed
which does not allow adequate control of steering and
stopping. Reduce speed if towed load is not equipped with
brakes.
▲ Reduce speed on rough roads.
▲ Comply with national, regional and local laws.
▲ Do not fold or unfold the fertilizer applicator while the
tractor is moving (other than field lift).

NH3 System Narrative
This list describes a single-cooler anhydrous system with
section control. A dual-cooler system has two of
components through , and two additional
dual-tube tines . A single-section system lacks
components through and has only one of .
Refer to Figure 6 on page 29
A11.Acme cap
Suffocation, Blinding and Burning Hazards:
See “NH3: Safing Applicator Before Cart Hitch” on
page 55, for safe opening procedure.
This captive cap protects the inlet when no nurse
tank is connected. NH3might be sealed behind this
cap.
A12.Acme inlet
The nurse tank hose coupler connects here and
must have 13⁄4-4 female Acmea swivel coupler. See
page 58 for nurse tank connection.
A13.Coupler Inlet Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 38.
This fitting is carefully opened at normal and
abnormal disconnects, to bleed NH3 liquid and
vapor from the hoses (or to bleed just the nurse tank
hose upon breakaway). It is also opened prior to
Acme cap removal to verify that the line is
discharged. See “NH3: Making Nurse Tank
Connections” on page 58, “NH3: Unhitching
Nurse Tank” on page 67 and “NH3: Breakaway
Event” on page 65.
A11 A24
A49
A35 A39 A40
A7
A14.Breakaway Coupler
Upon Event: Probable Chemical Hazard:
See “NH3: Breakaway Event” on page 65.
This assembly is designed to separate and seal the
lines if between 300 to 400 pounds of pull force is
applied to the nurse tank hose. In normal
operations, this does not happen.
Should the hitch fail, and both safety chains fail, or
an operator makes serious basic safety errors, the
breakaway separates to protect the hoses from
rupture. Spring-loaded checks inside the breakaway
seal both ends of the now-broken connection. If the
line was charged, 60 cc of liquid NH3is released on
breakaway.
Resetting a parted breakaway coupler is a complex
operation requiring tools. Consult the breakaway
manual for details. More significant matters are
safing the applicator and nurse tank, then correcting
the cause of the breakaway. See “NH3: Breakaway
Event” on page 65.
A15.Breakaway Hydrostatic Relief Valve
In normal operation, this valve does not activate.
It is designed to open at 375 psi, well above the
250-265 psi operating pressure of the nurse tank’s
main pressure relief valve.
Operator action is periodic inspection, and to
replace this hydrostatic relief valve, a time-dated
part, when it reaches the end of its operating life
(see page 114). See “Hydrostatic Relief Valve
Maintenance” on page 112 for maintenance.
Valve function: when operating valves are closed on
both sides of the breakaway (or on just the
applicator side upon a breakaway event), NH3 can
be trapped in the breakaway coupler. As the NH
warms, it could create dangerously high pressure.
This relief valve opens to vent excess pressure.

A16.Coupler Outlet Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 38.
This fitting is kept closed in normal operations.
When the breakaway is properly coupled, the inlet
bleed valve bleeds the entire assembly, and
A13
applicator supply hose. On breakaway, this valve is
used to bleed the applicator side of the
disconnection. See “NH3: Breakaway Event” on
page 65.
A17.Supply Hose
This connects the breakaway coupler to the
emergency shut-off valve. Operator action is to
replace this hose, a time-dated part, when it
reaches the end of its operating life (see page 114).
A18.Emergency Shut-off Valve
The handle of this is valve has a rope which is
routed to the tractor cab (see page 38). Closing this
valve stops NH3flow to the cooler, metering system
and tines. There can still be a substantial amount of
NH3 in the system, for some time, with this valve
closed. See the “Using Anhydrous Ammonia
Safely” manual (407-551M) for emergency
operation.
A19.Strainer
This filter contains a 20 mesh screen and two
ceramic magnets to remove debris from the NH
flow.
A20.Strainer Magnets
These capture ferrous metal debris of any size.
They need to be cleaned every 4 to 5 tank loads.
See page 117.
A21.AccuFlow™ Super Cooler (Heat Exchanger)
For effective application, NH3needs to remain in the
liquid state until released underground. This is
accomplished by refrigeration. Some of the flow is
tapped , fed back to the cooler at , vaporized
and used to chill the fluid passing from to .
A32 A34
A22 A24
A22.Cooler Intake
Liquid NH
enters the cooler here.

A23.Cooler Hydrostatic Relief Valve
In normal operation, this valve never activates. NH
3
can get trapped in the system between the
emergency shut-off valve and the On/Off
valve , if both valves are closed while the system
A31
A18
is charged. As the liquid warms and pressure rises,
this valve protects the system with periodic
releases.
This valve is set to activate at 350 psi, higher than
the nurse tank’s relief valve.
Operator action is periodic inspection, and to
replace this hydrostatic relief valve, a time-dated
part, when it reaches the end of its operating life
(see page 115). See “Hydrostatic Relief Valve
Maintenance” on page 112 for maintenance.
A24.Cooler Outlet
Chilled liquid NH3 exits the cooler here.
A25.Flow Meter
This fitting converts fluid flow to pulses for the
SCS 450 controller. It has a range of 1-60 gpm. A
tag on the cable lead provides a “METER CAL”
number specific to the installed meter (and accurate
only for NH3 fluid flow, and not NH3 vapor flow).
A26.Drain Cap
The plumbing cross and lower cap below the
temperature gauge are provided to allow the gauge
3
probe to be exposed to the full NH3 stream. This
cap does not require periodic clean-out.
A27.Temperature Gauge
This gauge reports the temperature of the chilled,
flowing, NH3. When NH3 is not flowing, this gauge
slowly drifts up to ambient temperature.
Checking the temperature and pressure gauges
A28
against the chart in the “Using Anhydrous
Ammonia Safely” manual (407-551M), or in the
Raven AccuFlow™ manual, indicates whether the
flowing NH3 is in a liquid state.
Normal field temperatures of the chilled flowing NH
3
are in the range 20 to 83°F (-7 to 28°C).
2014-04-22 Table of Contents Index 407-613M
24 NP3000 and NP3000A Table of Contents Index Great Plains Manufacturing, Inc.
A28.Pressure Gauge
This gauge reports the pressure of the NH
exits the cooler. If line valves are closed, a pressure
reading above zero indicates NH
between the emergency shut-off valve and the
On/Off solenoid valve (the Control Valve
A31 A30
is present
3
A18
does not completely close).
Checking the pressure and temperature against
the chart in the “Using Anhydrous Ammonia
Safely” manual (407-551M), or in the Raven
AccuFlow™ manual, indicates whether the flowing
NH3 is in a liquid state.
When valves are open but NH3 is not flowing, this
gauge normally reads within 5 psi of the nurse tank
pressure gauge . If they are materially different
A17
at zero flow, one of the gauges may be defective.
When NH3 is flowing, the pressure reported by this
gauge is lower than the tank pressure.
A28
A29.Cooler Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 38.
This valve is normally closed. It is used to bleed
trapped NH3 from the cooler system when valves
are closed. It can also be used to accelerate
clearing the cooler system for maintenance.
A30.Control Valve
This is a variable electronic valve controlled by the
SCS 450. It is the primary control point for
application rate. When power is off, this valve
remains at its most recent setting.
This valve has a visible indicator above the valve
ball casing, indicating whether open, closed or in
between.
When commanded to a rate of zero, this valve does
not completely close. Use shut-off valves to
completely stop flow. A full slew from fully open to
minimum takes approximately 9 seconds.
A27
after it
3
A31.Master Shut-Off Valve
This is the normal control for starting and stopping
total application flow in the field (for turns, etc.). This
component is an open/close solenoid valve
controlled by the “MASTER” switch on the SCS 450.
When power is off, this valve remains at its most
recent setting.
This valve has a visible indicator above the valve
ball casing, indicating whether open or closed.
Operation of this valve is essentially instantaneous.
Its valve ball is equipped with a downstream relief
orifice.
A32.Refrigerant Tap
A small amount of the NH3flow is taken at this point
to provide refrigeration at the cooler. There are no
operational items for this fitting.
A33.Refrigerant Line
This tubing passes tapped refrigerant NH3 to the
cooler. Operator action is to replace this tubing,
a time-dated part, when it reaches the end of its
operating life. See page 115.
A34.Cooler Refrigerant Inlet
Tapped refrigeration flow enters the cooler at this
fitting, and is vaporized to chill the liquid entering at
fitting . There are no operational items for this
A22
fitting.
A35.Section Control Check Valve
(Section Control Option Only)
This prevents back flow when section shut-off
valves are off with NH3 present. There are no
A39
operational items for this fitting.
A36.Section Control Bleed Valve
Suffocation, Blinding and Burning Hazards:
See “About Bleed Valves:” on page 38.
(Section Control Option Only)
This valve is normally closed. It is used to bleed
trapped NH3 from the section control system if all
section valves are closed.

407-613M Table of Contents Index 2014-04-22
Great Plains Manufacturing, Inc. Table of Contents Index Application Overview 25
A37.Section Control Relief Valve
(Section Control Option Only)
In normal operation, this valve never activates.
NH3can get trapped in the system between the
section control check valve and the section
shut-off valves , if all section valves are closed
A39
A35
while the system is charged. As the liquid warms
and pressure rises, this relief valve protects the
system with periodic releases.
This valve is set to activate at 350 psi.
Operator action is periodic inspection, and to
replace this hydrostatic relief valve, a time-dated
part, when it reaches the end of its operating life
(see page 115). See “Hydrostatic Relief Valve
Maintenance” on page 112 for maintenance.
A38.Section Flow Divider
(Section Control Option Only)
This is a CDS-John Blue®Impellicone® manifold.
It evenly splits the NH3 flow for distribution through
the row flow dividers . There are no operational
A40
items for this component.
A39.Section Shut-Off Valves
(Section Control Option Only)
These are the normal controls for suspending
per-section application flow in the field (for point
rows, pass overlap, etc.). These are open/close
solenoid valves controlled by the “BOOMS”
switches on the SCS 450.
When used with the SCS 450 or other suitable
sectional application controller, shutting off a
section causes the total flow to be reduced by1⁄3 of
the all-sections-on rate, keeping the rate constant
for the section(s) still active.
Each section valve has a visible indicator above the
valve ball casing, indicating whether open or closed.
Operation of each section valve is essentially
instantaneous. However, there is considerable
residual NH3in the section flow divider and delivery
tubes after shut-off. When console power is off, the
valves remain at their most recent setting.
The valve balls are equipped with a downstream
relief orifice.
A40.Row Flow Divider(s)
This is a CDS-John Blue®Impellicone® manifold. It
evenly splits the NH3flow for distribution through the
delivery tubes . There are no operational items
A45
for this component.
A41.Flow Divider Manifold Inlet
NH3 liquid flow enters the flow divider here.
A42.Flow Divider Pressure Gauge
This gauge reports the pressure prior to flow
division. It normally reads lower than the cooler and
nurse tank pressure gauges.
A43.Flow Divider Outlet
Each of these ports receives an equal fraction of the
NH3 liquid flow.
A44.Flow Divider Plug
Unused ports are plugged with a steel NPT plug.
Unused ports do not affect flow balance at the other
ports.
A45.Delivery Tube
This tubing passes NH3 liquid flow to the tines.
Operator action is to replace this tubing, a
time-dated part, when it reaches the end of its
operating life. See page 116.
A46.Coulter Tine (Single)
Tines inject the liquid NH3. All but two (or four) of the
rows are equipped with tines having a single smaller
liquid delivery tube. Tines need frequent inspection
for wear and damage.
A47.Cooler Vapor Outlets (2)
Two vapor outlets direct the now-gaseous
refrigerant flow (that entered at ) to two special
tines per cooler.
A49
A34
A48.Vapor Tube
This tubing passes NH3vapor flow to the dual tines.
Operator action is to replace this tubing,
a time-dated part, when it reaches the end of its
operating life. See page 116.
A49.Coulter Tine (Dual)
There are two of these special tines per cooler (four
total on a dual-cooler applicator). They direct the
vaporized refrigerant NH3 gas into the soil at the
larger rear vapor tube. They are otherwise identical
to the single-tube tines .

The following callouts are for trailing nurse tank cart
components. See the “Using Anhydrous Ammonia
Safely” manual (407-551M) for all nurse tank callouts
( - ). The present manual lists only those required
A1
A36
for applicator field operations.
A6.Acme Parking Plug
A threaded stud (or other means) for storage of the
outlet hose when not coupled to the applicator.
Excess NH3 Release Hazard:
If the outlet hose is entirely dismounted (both ends free)
for transport and storage, and both ends are 13⁄4-4 Acme,
be sure about which end is which. Installing a hose
backwards can result in needless excess NH3 release at
unhitching, or a line segment unprotected by bleed and/
or relief valves.
A7.Acme Female Hose Coupler
This end of the hose connects the tank withdrawal
valve to the leading applicator inlet at the
A13 A12
breakaway coupler. For use with a Nutri-Pro
®
applicator, the outlet end of the hose must be
equipped with a 13⁄4-4 female Acme fitting.
The outlet end of the hose has a swivel collara or
shroud containing the female Acme fitting. This
allows connection without needing to twist the hose.
Acme hose couplers are intended for hand
tightening only. Do not use tools to make the
cart-applicator connection. A liquid-tight seal is
made by the gasket in the male Acme fitting on the
applicator break-away coupler.
For dual-tank carts, each tank usually has its own
hose.
A8.Outlet Hose Assembly
The hose may have zero, one or two operating
valves , one or more bleed valves , and a
hydrostatic relief valve . The outlet end may
A10 A11
A12
have an Acme. plug.
Hose valves are typically hand wheel valves, or
lever valves. Read any documents provided for the
valves. Have the terminal or dealer explain how the
valves work.
Suffocation, Blinding and Burning Hazards:
Never test an anhydrous ammonia hose valve unless you
are absolutely certain the hose and valve bodies are
empty, or both hose ends are securely connected to
sealed systems.
▲ A two-valve hose can contain a substantial amount of
NH
even when completely disconnected. See “Avoid
3
Line Traps” on page 106.
▲ Older ball valves can contain NH3 inside the ball
when closed, even though disconnected at both ends.
See “Avoid Ball Traps” on page 107.
Follow instructions for bleeding and checking. Never use
a valve handle as a carrying handle. Keep hands clear of
bleed valves when carrying a hose.
A9.Nurse Tank Hose Body
NH3 hoses are time-dated components. Operator
action is to replace the assembly when it
A8
reaches the end of its operating life.
A10.Hose Valve(s)
The hose may have zero, one or two operating
valves .
A10
Excess NH3 Release and Trapping Hazards:
Understand hose and tank withdrawal valve functions
and sequencing. This manual presumes a hose with a
single outlet-end shut-off valve , and a tank outlet
with a withdrawal valve . If the hose in use is
A10
