Important Information: Recommendations and Best Practices 3
IMPORTANT INFORMATION
RECOMMENDATIONS AND BEST PRACTICES
HOSE ROUTING
The word “hose” is used to describe any flexible, fluid carrying components. Use the following guidelines and
recommendations when connecting and routing hoses while installing or maintaining this Raven system:
• Leave protective caps/covers over hose ends until connecting the end into the hydraulic system to help
prevent contaminants from entering the system.
• Follow existing hose runs already routed on the implement as much as possible. Proper hose routing should:
•Secure hoses and prevent hoses from hanging below the implement.
•Provide sufficient clearance from moving components and operational zones around shafts;
universal joints and suspension components; pulleys, gears, belts, and chains; moving linkages,
cylinders, articulation joints, etc.
•Protect hoses from field debris and surrounding hazards (e.g. tree limbs, fence posts, crop stubble,
dirt clumps or rocks that may fall or be thrown by the implement).
•Protect hoses from sharp bends, twisting, or flexing over short distances and normal implement
operation.
•Ensure sufficient length for free movement of the implement during normal operation and prevent
pulling, pinching, catching, or rubbing, especially in articulation and pivot points. Clamp hoses
securely to force controlled movement of the hose.
•Avoid abrasive surfaces and sharp edges such as sheared or flame cut corners, fastener threads or
cap screw heads, hose clamp ends, etc.
•Avoid areas where the operator or service personnel might step or use as a grab bar.
• Do not over tighten threaded joints.
• Use thread sealant on all threaded joints.
• Do not connect, affix, or allow hoses to come into contact with components with high vibration forces, hot
surfaces, or components carrying hot fluids beyond the temperature rating of hose components.
•Hoses should be protected or shielded if routing requires the hose to be exposed to conditions
beyond hose component specifications.
• Avoid routing hoses in areas where damage may occur due to build up of material (e.g. dirt, mud, snow, ice,
etc.).
HARNESS ROUTING
The word “harness” is used to describe any electrical cables and leads, both bundled and unbundled. Use the
following guidelines and recommendations when connecting and routing harnesses while installing or
maintaining this Raven system:
• Leave protective caps/covers over harness connectors until needed to avoid dirt and moisture from
contaminating electrical circuits.
• Secure the harness to the frame or solid structural members at least every 12 in [30 cm].
• Follow existing harness runs already routed on the implement as much as possible. Proper harness routing
should: •Secure harnessing and prevent the harness from hanging below the implement.
•Provide sufficient clearance from moving components and operational zones around shafts;
universal joints and suspension components; pulleys, gears, belts, and chains; moving linkages,
cylinders, articulation joints, etc.

CHAPTER 1
4 Boom Recirculation Installation and Operation Manual for Case IH 50 Series Patriot Sprayers
•Protect harnessing from field debris and surrounding hazards (e.g. tree limbs, fence posts, crop
stubble, dirt clumps or rocks that may fall or be thrown by the implement).
•Protect harnessing from sharp bends, twisting, or flexing over short distances and normal
implement operation.
•Connectors and splices should not be located at bending points or in harness sections that move.
•Ensure sufficient length for free movement of the implement during normal operation and prevent
pulling, pinching, catching, or rubbing, especially in articulation and pivot points. Clamp harnessing
securely to force controlled movement of the harness.
•Avoid abrasive surfaces and sharp edges such as sheared or flame cut corners, fastener threads or
cap screw heads, hose clamp ends, etc.
• Do not connect, affix, or allow harnessing to come into contact with components with high vibration forces, hot
surfaces, or components carrying hot fluids beyond the temperature rating of harness components.
•Harnessing should be protected or shielded if routing requires the hose to be exposed to
conditions beyond harnessing component specifications.
• Avoid routing harnesses in areas where damage may occur due to build up of material (e.g. dirt, mud, snow,
ice, etc.).
• Avoid routing harnesses in areas where the operator or service personnel might step or use as a grab bar.
IMPORTANT: Avoid applying direct spray or pressure washing of electrical components and connections. High pressure
streams and sprays can penetrate seals, cause corrosion, or otherwise damage electrical components.
When performing maintenance:
• Inspect electrical components and connectors for corrosion, damaged pins or housings, etc. Repair or replace
components or harnessing as necessary.
• Ensure connectors are kept clean and dry. Apply dielectric grease to the sealing surfaces of all connections
exposed to moisture, dirt, debris, and other contaminates. Repair or replace harnessing as necessary.
• Clean electrical components with pressurized air, aerosol electrical cleaning agent, or low pressure rinse.
• Remove visible surface water from electrical components and connections using pressurized air or an aerosol
cleaning agent. Allow components to dry thoroughly before reconnecting cables.

Introduction: Theory of Operation 5
CHAPTER 2 INTRODUCTION
Thank you for purchasing the boom recirculation system. This system is designed to allow the equipment operator
to prime the boom or agitate chemical in the boom plumbing without spraying chemical on the ground. This
system allows the operator to adjust the recirculation flow based upon the spray system or the chemical needs
and will automatically disengage when normal application is started or if a chemical injection system is detected.
This manual applies to the following machines:
Make. Case IH
Model. 3050 and 4050 series sprayer platforms with AIM Command Flex II (ACF II)
Boom Configurations. 90’ - 135’ Booms
System Requirements:
• Must have the CNH RCM-Sprayer ECU
• Boom plumbing kit installed
• Product cable with electronic recirculation valve connection required
• Recirculation authorization code (077-0180-296)
THEORY OF OPERATION
When the recirculation system is active, the spray system is not spraying, and NCVs are off, the electric return valve
opens fully. The main pump circulates the spray liquid from the main tank through the existing supply plumbing to
the section valves.
Section valves actuate open in pairs, starting with the outermost left and right sections and progressing inward.
The section valves turn on and off to circulate fluid for the user-defined auto-operation time for each section of
the spray system. This keeps the liquid circulating, allowing the system to purge any air, break up chemical
deposits, and agitate any separated chemicals through the system without having to spray out of the nozzles.
Product returns through the throttling valve and electric return valve until the electric return valve automatically
turns off when spraying resumes. The throttling valve is used to dampen the pressure spike affects of the electric
return valve closing when spraying resumes. The individual recirculation hand valves should be used to separate
sections when not using NCVs (Bypass and High Flow/High Flow VP Modes) and to isolate boom plumbing
sections if maintenance is required or damage to a plumbing component occurs that causes a leak.

CHAPTER 2
6 Boom Recirculation Installation and Operation Manual for Case IH 50 Series Patriot Sprayers
PREPARING FOR INSTALLATION
Before installing boom recirculation, park the machine where the ground is level, clean, and dry. Leave the
machine turned off with the booms unfolded for the duration of the installation process.
During the installation process, follow good safety practices. Be sure to carefully read the instructions in this
manual as you complete the installation process.
RECOMMENDATIONS
Raven Industries recommends the following best practices before installing or operating the boom recirculation
system for the first time, at the start of the season, or when moving the boom recirculation system to another
machine:
• Visually inspect the system for any damage including cracked or broken fittings, worn or pinched hoses,
corrosion around electronics and cables, etc.
• Set the system to operating position with the hand valves and throttling valve open with the flush valves closed.
Then perform a leak test.
• Rinse the boom and perform a boom air blowout to thoroughly clean the system.
TOOLS NEEDED
The following tools are recommended for installation of the boom recirculation system:
• Tape measure
• Hose cutter for up to 2” OD spray hose
• 2 Slip Joint Pliers (approx. 10” size)
• Metric and Imperial Wrench Set
• 5/16” Nut Drivers for hose and flange clamps
• Side cutters
• Corrosion X-HD spray
POINT OF REFERENCE
The instructions in this manual assume that you are standing behind the machine, looking toward the cab.
