All parts supplied are selected will be inoperative until the installation is specially to fit the sprayer to facilitate a complete. Any installation procedure complete installation. However, NORAC requiring boom movement will need cannot guarantee all parts fit as intended to be done first.
The parts that come with your UC4+ System are shown below in their general installation configuration. Figure 2: UC4+ Spray Height Control Components The use of dielectric grease is not recommended on any NORAC electrical connections. To ensure all stainless steel hardware does not gall or seize apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation.

o Adjust the slant speed of the boom until the full stroke (from full counter-clockwise to full clockwise) is 6 seconds (Figure 4). This is the time required for the slant cylinder to travel from fully extended to fully retracted, or vice-versa. 6 seconds Figure 4: Setting the Slant Speed...
4.3 W ING SENSOR INSTALLATION 1. Assemble the breakaway sensor mounting Brackets (B11) as show in Figure 5. Figure 5: Breakaway Sensor Assembly To assemble the breakaway sensor bracket: a) Assemble the bolt and nut into the collar. b) Grease the bottom edge of the collar and the angled tube of the base. c) Place the collar onto the angled tube of the mounting base.

3. The sensor mounting brackets can be installed with the mounting base in front of or behind the mounting tube (the difference in mounting can be seen in Figure 7 and Figure 8). When installing the UC4+ sensors (E02), start with the smallest serial number on the left hand side proceeding to the largest serial number on the right hand side (Figure 13).
4.3.1 General mounting rules for UC4+ ultrasonic wing sensors: a) In its lowest position, the sensor mouth must be 9 inches or more from the ground. b) The bottom of the sensor must be at least 9 inches in front of the spray nozzles. c) The bottom of the sensor must be at least 9 inches above the spray nozzles.
RAU aluminum boom clamp, as illustrated below. Figure 9: UC4 Sensor Bracket Mounted to Boom using RAU HSA Boom Clamp Using this clamp will also require adjusting the width of the hole in the NORAC bracket to accommodate the larger bolts and differences in dimensions between the 2 parts.
Use the square bracket mounting plate and the included hardware to mount the UC4 bracket to the HSS boom, as illustrated. NORAC hardware Figure 11: HSS Boom Mount the UC4 bracket to the HSS boom as shown below, inside of the break-away section.

NOTE: When arranging height sensors, install the serial numbers from lowest to highest, left to right. Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon installation. Figure 13: Sensor Serial Number Installation Location (example)
4.4 E LECTRICAL NSTALLATION Ensure the power switch is turned OFF for the remainder of the installation (bottom of switch pressed IN). Use caution when handling the 12 V power line of the sprayer wiring. 4.4.1 Control Panel Mounting Install the UC4+ control panel (E01) in the cab of the sprayer with the supplied mounting bracket.
4.4.2 Cable Installation Figure 15: Cable Routing Overview 1. Connect C10 to the UC4 control panel in the sprayer cab. Ensure that both plugs (P16A and P4) are connected to the panel. 2. Route the receptacle end (R16) of C10 to the exterior of the cab and connect to C11 at the hitch.
4.4.3 RAU Valve Connections 1. Refer to Figure 16. 2. Connect the RAU Valve Drive PCB (C12) to the NORAC harness (Item C11) using harness C17. Connect all 3 Weatherpack connectors. 3. Plug item C12 into C18, and securely fasten the module to the sprayer with cable-ties.

OMPLETING THE NSTALLATION 1. Test the functionality of the original manufacturer’s boom controls. The NORAC Control Panel (E01) does not need to be powered up for the original switches to function. Unfold the booms and raise/lower each boom and main section. Confirm that the cabling/hoses are agreeable to the entire range of motion.
