1 Introduction Congratulations on your purchase of the NORAC UC5 Spray Height Controller. This system is manufactured with top quality components and is engineered using the latest technology to provide operating reliability unmatched for years to come. When properly used the system can provide protection from sprayer boom damage, improve sprayer efficiency, and ensure chemicals are applied correctly.

P - PIPE The 6MBP plugs (F03) are only used for the single acting plumbing installation. 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.

Optional Pressure and Tank Hose Kit (P/N: 44865-49) If you require a separate pressure and tank line from your tractor to your NORAC valve block, you can order the hoses and fittings as a kit (P/N: 44865-49). Part Number Name...
4 Pre-Install Checklist The pre-install checklist is necessary to check the existing sprayer functionality before the installation. 1. Unfold the sprayer over a flat, unobstructed area (i.e. no power lines…etc.). 2. Ensure all boom-fold operations are functional (place a check mark in boxes below). 3.
5 Ultrasonic Sensor Installation Bracket Assembly Assemble the breakaway sensor bracket as illustrated in Figure 6, following the instructions below. Figure 6: Breakaway Bracket Assembly 1. Compress the spring and insert it together with the collar into the base. 2. Slide the tube through the assembled part. 3.

Ultrasonic Sensor Serial Number Arrangement When installing the UC5 sensors, start with the smallest serial number on the left-hand side, and proceed to the largest serial number on the right hand side. Each UC5 sensor has a serial number stamped on the sensor housing.
Page 15
Ultrasonic Sensor Mounting Guidelines The following guidelines will ensure optimal sensor performance and prevent sensor measurement error. These rules should be followed for both the wing sensors and the main lift (middle) sensor. 1. In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground (A). 2.
Page 16
If the sensor is mounted to this portion of the boom, the system will force the boom downwards towards the ground as the boom folds backwards. 4. Mount the NORAC UC5 ultrasonic sensor into the sensor bracket and run the sensor cable through the sensor tube.

Main Lift Sensor Installation Figure 10: Main Lift Bracket Assembly 1. There are a variety of ways to mount the main lift bracket on most sprayers. The bracket should position the sensor approximately in the center of the sprayer, forward of the boom.
6 Roll Sensor Installation Bracket Assembly 1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine screw and nylon lock-nuts. 2. The orientation of the mounted roll sensor to the roll sensor bracket will depend on the bracket mounting.

Roll Sensor Mounting Guidelines: Trapeze-Suspended Booms 1. When mounting the roll sensors, mount one to the trapeze link (boom frame) and one to the trapeze support (chassis). For optimal performance, minimize the distance from the boom frame roll sensor to the pivot point (A) and minimize the vertical distance between the chassis roll sensor and the pivot point (B).

Figure 21: Valve Module Bracket Installation 5. Connect the valve module CANbus to cable C01 from the control module. Route cable C02 from the other CANbus connector to the input module. 6. With the valve module securely mounted to the valve block, connect the valve cables (C10), to the valve coils.
Page 25
Input Module 1. Install the input module (E03) on the boom near the Hardi valve block. Secure it to the boom using cable ties or optional brackets 2. Connect the free end of the CANbus cable (C02) from the valve module to the input module.
Follow existing cables and hoses to be sure the cable will not be pinched or stretched. Figure 24: UC5 Module Locations and Cable Connections 5. At the sensor brackets, attach a 2-way coupler with terminator (E20) to the sprayer boom.
Valve Assembly: Single Acting 1. On a clean surface remove the plastic plugs from the block. 2. Install two 6MB 6MJ (F02) fittings into the P and T ports on the NORAC block. Tighten to 18 ft-lbs (24 Nm). 3. Insert the two orifices (F01) into the “B” ports with the notch facing out.
Page 28
Valve Assembly: Double Acting 1. On a clean surface remove the plastic plugs from the block. 2. Install two 3/8” x 1/4” BSPP (HD01) fittings into the P and T ports on the NORAC block. Tighten to 18 ft-lbs (24 Nm).
Page 29
Valve Block Mounting 1. A suitable mounting location for the valve block is illustrated in Figure 27. 2. Insert the threaded rod into the block and use a hex nut to hold the rod. The block holes are 3/8” NC-1” deep. If bolts are used instead of the threaded rod, ensure the bolts thread in at least 3/8”.

Figure 4. 2. Install the 90 degree fittings on hoses H03 onto the “A” ports on the NORAC valve block. 3. Install the 90 degree fittings on hoses H02 onto the “A” and “B” ports on the NORAC valve block.
Begin the AUTOMATIC SYSTEM SETUP procedure as described in the UC5 Spray Height Control Operator’s Manual. 5. For optimal performance of the UC5 system, there should be very little play at the hitch clevis. The addition of polymer washers can help tighten up this connection (Figure 30).
