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.

4 INSTALLATION PROCEDURE
4.1 FUNCTIONALITY CHECK
Before beginning the install, ensure all hydraulic
boom functions are operating properly on the
sprayer.
oAll Fold Functions
oMain Lift Function
oWing Tilt Functions
oSlant Function
4.2 EXISTING SYSTEM CHECK
oInspect slide pads and wear surfaces for
excessive wear. Replace or adjust if
necessary.
oEnsure the boom guide-rods are set to
the “tapered” position (factory setting)
oSet boom suspension to be critically
damped (Figure 5). Adjust the boom
damper accordingly.
A) Unlock the pendulum, and push
boom tip down approximately 75 cm
(30 inches).
B) Hold the boom steady for a moment,
and release.
C) Ensure the boom returns to its
relaxed state as quickly as possible,
with little to no overshoot.

4.3 WING SENSOR INSTALLATION
1. Assemble the Breakaway Sensor Mounting
Brackets (B13) as show in Figure 6 and
Figure 7.
Figure 6 – Breakaway Sensor Bracket
Exploded View
Figure 7 – Breakaway Sensor Mounting
Bracket 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.
d) Install the spring between the collar and
the upper ring of the base.
e) Insert tube through assembly and tighten
the collar
2. Mount the sensor bracket onto the boom.
If possible, mount the sensor
brackets while the booms are in
their folded position to ensure
that they will not interfere with
anything when the boom is folded
for transport.
3. The sensor mounting brackets can be
installed with the mounting base behind
(Figure 10) or in front of the tube (Figure
8).
Mounting the sensor bracket to the
break-away section of the boom
may cause the boom to drop
suddenly as a break-away occurs.
This will occur on break-away
sections which lift as they break
away.
For optimal boom tip protection, it
is recommended that the sensor be
mounted within approximately two
feet (60cm) of the boom tip.
Please refer to the UC4+ Spray Height
Control system warranty at the end of the
UC4+ Spray Height Control
Operator’s Manual (M01) for
implications.
4. Mount the NORAC UC4+ ultrasonic sensor
(E02) into the sensor brackets. The sensors
should be oriented forward (ahead) of the
boom (see Figure 8 and Figure 10).
When installing the UC4+ sensors
(E02), start with the smallest
serial number on the left hand

10
side proceeding to the largest
serial number on the right hand
side (Figure 14).
5. Sensor cables should run through the
mounting bracket tube and then behind the
member the bracket is mounted onto.
Cable-tie the connector in place. The cable
must not be allowed to hang below the
boom (Figure 8).
Figure 8 – Another Acceptable Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown in
Figure 9.
Figure 9 - Poor Mounting
(Sensor Reading Off Boom)
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.
d) Ensure that there are no obstructions within
a 12-inch diameter circle projected directly
below the center of the sensor.
e) The sensor should be approximately vertical
at normal operating heights.

Below is the suggested mounting location for
the UC4 brackets on the HPZ (24-36m) or
HAZ (18-30m) booms. Mounting location is just
inside of the boom break-away section (A).

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.

4.4 MAIN LIFT SENSOR INSTALLATION
The General Mounting Rules for
UC4+ Ultrasonic Sensors (Section
4.3), must also be followed for the
Main Lift sensor.
4.4.1 FORCE / TWIN FORCE (HPZ/ HAZ)
1. Mount the main lift bracket (B11) as
illustrated in Figure 15. Ensure sensor
cable is routed properly and securely
fastened.
2. Mount the Ultrasonic sensor to the bracket.
Ensure the sensor has a clear view of the
ground. Ensure sensor cable is securely
fastened with cable-ties.

4.4.2 DELTA (LPZ)
No mounting bracket is required. Mount the
main lift sensor as illustrated in Figure 16.
Ensure sensor cable is securely fastened with
cable ties.
