Example:
Do not use high speed power tools/drills when installing hardware.
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.
Permatex Anti-seize lubricant is preferred, but other similar anti-seize products
may be used.

3Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines
or fittings. Hydraulic pressure will exist on the main lift circuit unless the main lift
is all the way down.
Component failure due to oil contamination is not covered under the NORAC
UC4.5 system warranty. It is recommended that a qualified technician perform the
hydraulic installation.
3.1 Expansion Block Assembly
1. Use Figure 1 as a reference for installing the hydraulics.
2. Loosen the existing 2-station valve block so that it can be moved and/or twisted for the
installation of the expansion block.
3. Remove the four 4MBP plugs from the 2 station valve block.
4. Coat the four o-rings in hydraulic oil and install them into the expansion block. Ensure the
o-rings are seated properly.
5. Attach the expansion block to the 2 station block using the included spring washers and
bolts.
6. Tighten the bolts to 31 ft-lbs.

3.2 Hydraulic Plumbing
1. Remove all plastic plugs from the NORAC expansion valve block (V01).
2. Install the 6MB 6MOR fittings (F04) into the “A” and “B” ports of the expansion block.
3. If the valve block is not already installed on the sprayer, install it as outlined in the UC4.5
Spray Height Control installation manual.
4. Attach the straight 6FORX fittings on hoses H02 to the “A” and “B” ports on the expansion
block. Route the free end of the hoses (H02) to the Case main lift tee, which is located
near the sprayer axle (Figure 3).
Figure 3: Case Main Lift Tee Location
5. Disconnect the “raise” hose that runs from the Case valve block to the main lift tee and
install the 6FORX 6MORT fitting (F03). Reconnect the “raise” hose to the tee.
6. Connect the NORAC hose (H02) that is connected to the B port on the NORAC
expansion block to the tee fitting (F03).
7. Disconnect the “lower” hose that runs from the Case valve block to the main lift tee and
install the 6FORX 6MORT fitting (F03). Reconnect the “lower” hose to the tee.
8. Connect the NORAC hose (H02) that is connected to the A port on the NORAC
expansion block to the tee fitting (F03).
Ensure no hydraulic components will interfere with any sprayer parts or be pulled
tight at any time.

3.3 Main Lift Valve Installation
If the sprayer was built prior to model year 2007 then the main lift valve may have to be
replaced with a part from your local Case Dealership. If the booms will go up, but not down;
the valve will need to be replaced. The Case part number of the valve is 87558232.
1. Lower the main lift all the way to the bottom. Turn off the sprayer ignition.
2. Loosen the hoses on each side of one of the main lift cylinders located at the back of the
sprayer. This is to remove any pressure from the system.
3. Remove the coils from the main lift valve, located under the sprayer.
Figure 4 - Main Lift Valve location
4. Thread the valve out of the valve housing and thread the new valve in.
5. Reinstall the coils onto the new main lift valve.

4Ultrasonic Sensor Installation
4.1 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.
2. Ensure that there are no obstructions within a 12-inch diameter circle projected directly
below the center of the sensor.
3. The sensor should be approximately vertical at normal operating heights.
Figure 5: Sensor Mounting Guidelines

4.2 Low Profile Bracket Mounting Guidelines
1. Minimize the distance between the bolts to prevent bending the bracket and prevent the
bracket from loosening over time.
2. Ensure the bracket is mounted tight against the bottom of the boom, minimizing the
distance between the boom structure and the angled flange.
Figure 6: Bracket Mounting Guidelines
A problem can arise if a sensor is not mounted correctly. It is possible for the
sensor to read off of the boom instead of the ground. This may only become
apparent once the control system is switched from soil to crop mode.
Also be careful that the sensor bracket does not collide with any other part of the
boom when the boom is folded to transport position. If possible, mount the sensor
brackets while the booms are folded to ensure they will not cause interference.

10
4.3 Main Lift Sensor Installation
1. The main lift mounting bracket (B21) is the bracket with the longer mounting flange.
2. 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. An example of this mounting is illustrated in Figure 8.
Figure 7: Bracket Mounting Example
3. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable through hole
and behind the bracket.
Figure 8: Example Mounting of the Main Lift Bracket
Avoid mounting the main lift sensor over or near a wheel-track. Measurements
from the wheel-track do not provide an accurate crop height and will cause
measurement and control error.
Ensure the bracket does not collide with any other part of the sprayer throughout
the full range of main lift motion.

5Electrical Installation
Figure 9: Cable Connections
Only components shown in black are included in this kit.

12
1. Locate the end of the previously installed valve extension cable (C11) at the rear of the
sprayer.
2. Disconnect the 6-pin shroud on C12 from the 6-pin tower on C11 and connect the 6-pin
connectors on cable C17 between the cables.
3. Connect the 3-pin shroud labeled “Connect to C11” on cable C17 to the free 3-pin tower
on C11.
4. Connect cable C19 to the 3-pin shroud on cable C17.
5. Connect the 2-pin connector on cable C19 marked ROLL CCW to the coil on the port
side of the valve block. The port side is the side of the valve block with the left and right tilt
hoses.
6. Connect the 2-pin connector on cable C19 marked ROLL CCW to the other free coil.
The pigtails on cable C19 are not used for this installation.
7. Connect the main lift sensor to the 8-way coupler using cable C07 and a 2-way coupler
(E12). Cable C07 and item E12 may not be needed if the 8-way coupler is mounted close
enough to the main lift sensor.
8. Tie up all cabling so that it will not interfere with any components on the sprayer.

13
6Software Setup
1. Start up the sprayer and test the sprayer’s functionality. The control panel does not need
to be powered on for the original switches to function.
Confirm that the cabling and hoses are agreeable to the entire range of motion.
2. If any functions do not work, review the hydraulic and electrical portions of this manual to
check for proper installation.
3. Turn on the power for the control panel using the switch on the side of the chassis.
4. Refer to the UC4.5 Spray Height Control Operator’s Manual to run an automatic install
with the CS4 type selected.
