NOTICE:
Every effort has been made to ensure the
accuracy of the information contained in
this manual. All parts supplied are selected
specially to fit the sprayer to facilitate a
complete installation. However, NORAC
cannot guarantee all parts fit as intended
due to the variations of the sprayer by the
manufacturer. Please read this manual
in its entirety before attempting
installation.
ATTENTION:
When installing the UC4+ Spray Height
Control system please be aware that at a
point in the installation your sprayer booms
will be inoperative until the installation is
complete. Any installation procedure
requiring boom movement will need
to be done first. Once the hydraulics
have been disconnected you must complete
the electrical installation before the booms
become operative.

Example:
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.

3 HYDRAULIC INSTALLATION
WARNING!
The hydraulic system creates very
high pressure. Before disconnecting
any hydraulic lines ensure all pressure
has been bled from the system.
IMPORTANT:
Component failure due to oil
contamination is not covered under
the UC4+ Spray Height Control
system warranty. It is recommended
that a qualified technician does the
hydraulic installation.
1. On a clean surface remove all plastic
plugs from the NORAC expansion valve
block (V01).
2. Install the 6MBP (F03) into the A port
of the expansion block (Figure 2).
3. Install the 6MB 6MJ fitting (F04) into
the B port of the expansion block
(Figure 2).
Figure 2 - Third Station Expansion
Block Assembly
4. Remove the three 4MBP plugs from the
UC4+ 2 station valve block.
5. Coat the three o-rings in hydraulic oil
and install them into the expansion
block.
Make sure the o-rings are
properly seated.
Figure 3 - Expansion Valve O-Ring
Placement
6. Thread the 4.5” studs into the UC4+
block.
Figure 4 - Expansion Valve Stud
Insertion
7. Attach the expansion block to the
UC4+ block using the included spring
washers and nuts.
8. Tighten the nuts on the studs to 31 ft-
lbs Torque.

Assembly
9. If the valve block is not already installed
on the sprayer, install it as outlined in
the UC4+ Spray Height Control kit
installation manual.
10. Attach hose H01 to port B on the
expansion block. Route the free end of
the hose (H01) to the Summers valve
block.
11. Remove the main lift hose from the
Summers valve block.
12. Place the 6FJXR 6MJT tee fitting (F02)
on the main lift fitting in the Summers
block.
13. Attach the Summers main lift hose and
hose H01 to the tee fitting.
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.

4 ELECTRICAL INSTALLATION
4.1 ROLL SENSOR INSTALLATION
1. Mount the roll sensor (E01) to the
included roll sensor bracket using the
machine screws and nylon lock nuts, as
illustrated in Figure 6.
The roll sensors must be
mounted tightly to the
brackets.
Figure 6 - Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
2. The roll sensor included in this kit is to
be mounted on the chassis as shown in
Figure 7. Ensure that the roll sensor
cabling is pointing to the right side of
the sprayer (when looking from the
rear).
3. Ensure that the roll sensor is relatively
level when the chassis is level.
4. Ensure that the chassis (Reference
Frame) roll sensor has the highest roll
sensor serial number (not including the
roll sensor with the temperature
probe).
Figure 7 – Chassis Roll Sensor
Mounting Location
5. Ensure the sensor is mounted
adequately and that the cable provides
enough slack.

4.2 ELECTRICAL INSTALLATION
Figure 8: Cable connections at rear of sprayer
Only the components shown in
black are included in this kit.
1. Connect the six pin shroud (T6B) to
the mating tower on the valve extension
cable (previously installed).
2. Disconnect the existing C13 cable and
install the 3 pin connectors between it
and the valve extension cable.
One connector on C17 will
remain disconnected. It is used
when installing other UC4+
options.
3. Install the two connectors on the end of
cable C17 to the expansion block.
The connector marked “Main
Down” goes on the port side of
the block. The port side of the
block is the side with the hoses.
4. Disconnect the valve extension cable
from the sensor cable and install cable
C05 between them.
5. Connect roll sensor E01 to cable C05.

5 COMPLETING THE INSTALLATION
You can now continue to install the
remainder of your UC4+ Spray Height
Control System.
If the system is fully installed then refer to
the UC4+ Operators Manual to run an
Automatic Install with the SM3 type
selected.
