4 INSTALLATION PROCEDURE
4.1 EXISTING SYSTEM CHECK
It is necessary to check the existing system’s
functionality before installing the UC4+
Spray Height Control system.
1. Drive your sprayer onto a flat piece of
land, with unobstructed boom movement
(e.g. no power lines).
2. Test that all boom functions operate
correctly. As you test each function
check it off in Table 3.
It is necessary to test the boom
functions in all directions

4.2 BOOM SPEED TEST
IMPORTANT:
Raise/lower all boom sections several
times to warm up the hydraulic system.
Grease all moving parts for consistent
results.
1. Lower each boom and main section as
close to the ground as possible.
2. Set your sprayer at field working RPM
on the throttle and mark this value in
Table 4.
You will need a stopwatch or a
watch that displays “seconds” for
the next step.
3. Raise the LEFT boom from its extreme
LOW position to the very TOP of its
travel. Record the time this takes in
Table 4, “Trial #1” for “Left UP”.
4. Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its
travel. Record this time in Table 4,
Trial #1, for “Left DOWN”.
Be careful when lowering the
booms so they don’t hit the
ground.
5. Similarly, record two more time trials
(Trial #2 & #3) for the LEFT boom and
record in Table 4
6. Repeat Steps 1 through 5for the
RIGHT, MAIN and ROLL functions.
Your sprayer may not have a roll
feature.
7. Average the three trials recorded for
each boom movement and record this
calculation in the “Average Time” slot in
Table 4.
8. These “Average Times” now represent
how quickly your system can react to
manual control. In Section 1.1, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.

4.3 WING SENSOR INSTALLATION
1. Assemble the Breakaway Sensor
Mounting Brackets (B11) as show in
Figure 5 and Figure 6.
Figure 5 – Breakaway Sensor Bracket
Exploded View
Figure 6 – 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 9) or in front of the tube (Figure
7).
It is advised to avoid mounting the
sensor bracket to a breakaway
portion of the boom because a
breakaway action can cause the
UC4+ Spray Height Control
system to force a boom close to the
ground.
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 7 and
Figure 9).
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 10).

10
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 7).
Figure 7 – Another Acceptable Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown
in Figure 8.
Figure 8 – 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.

4.4 MAIN LIFT SENSOR INSTALLATION
1. Assemble the main lift sensor bracket
(B11) as shown in Figure 11.
Figure 11 – Main Lift Sensor Bracket
2. The bracket can then be mounted to the
lowest frame member on the center
section of the sprayer. The bracket
should be mounted so the sensor
mounting collar is in approximately the
center of the sprayer and ahead of the
boom (Figure 12 and Figure 13).
The sensor mounting collar must
not be behind the sprayer’s wheel.
The General Mounting Rules for
UC4+ Ultrasonic Sensors, from the
previous section, must be followed.

4.5 ROLL SENSOR INSTALLATION
Mount the roll sensors to the included
roll sensor brackets using the machine
screws and nylon lock nuts, as illustrated
in Figure 14
The roll sensors must be mounted
tightly to the brackets.
Figure 14 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure
15
a) The smaller the distance between A
and Bin Figure 15, the better the
performance will be.
b) Ensure the roll sensors are sitting
relatively level when the sprayer
chassis and boom are level.
c) Both roll sensors must be mounted
with the circular AMP connector
facing towards the Right-Hand Wing
(when looking from the rear of the
sprayer).

4.5.1 Boom Frame Roll Sensor
Mounting
1. Use the supplied hardware to mount the
boom frame roll sensor (E04) as shown
in Figure 16.
When mounting the boom frame roll
sensor follow these guidelines:
a) To prevent bending the bracket,
ensure bolts are placed as close
together as possible (minimize Cin
Figure 16).
b) Be sure to use the roll sensor without
the temperature probe (E04).
c) When the boom is centered (not
rolled over) the roll sensor should be
level with respect to the sprayer
chassis.
d) It is best to mount the roll sensor to
the left hand trapeze link (when
looking from the rear of the sprayer).
e) The roll sensor AMP (circular)
connector MUST exit towards the
right had wing (when looking from
the rear of the sprayer).
Figure 16 – Boom Frame Roll Sensor
Mounted to a Trapeze Link
2. Cable-tie the sensor connector to the
frame with enough slack to allow the
link to rotate.
Make sure the bracket does not
collide with any parts of the
sprayer when the boom rotates.
Also ensure there is enough slack
to allow the roll sensor to rotate.

15
4.5.2 Chassis Roll Sensor Mounting
1. It is often best to cable tie the chassis
roll sensor in place. When mounting the
chassis roll sensor follow the guidelines
and refer to Figure 17.
The chassis roll sensor must be
mounted on a portion of the
sprayer that does not pivot and is
as close to the boom frame roll
sensor as possible (Figure 15).
a) Make sure you are using the roll
sensor with the temperature probe
(E03).
b) Ensure the roll sensor is level with
respect to the chassis.
c) The AMP (circular) connector
MUST exit towards the right
hand wing.
d) Make sure the temperature probe is
able to reach the side of the valve
block.
Figure 17 – Chassis Roll Sensor Mounting
2. Fasten the temperature probe to the
UC4+ valve block, using the supplied
3/8”x1/2” bolt as shown in Figure 18.
3. Cable-tie the temperature probe cable
and AMP (circular) connector securely
to a frame member.
Check that the roll sensors and
cables will not interfere with, or
come into contact with any parts of
the sprayer.

4.6 HYDRAULIC INSTALLATION
WARNING!
The hydraulic system creates very high
pressure. Before disconnecting any
hydraulic lines ensure all pressure has
been bled from the system. When
changing the boom hydraulic hoses leave
the booms in TRANSPORT POSITION.
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.
4.6.1 Valve Assembly
1. On a clean surface remove all plastic
plugs from the NORAC hydraulic Valve
(V01) (Figure 19).
Figure 19 – NORAC Valve Block
2. Install the male adapters (F02) on the
"P" and "T" ports and tighten to 18 ft-
lbs.
3. At this point the sprayer hydraulic
system must be identified as being single
acting or double acting.
4.6.1.1 Double Acting Assembly
1) Install the orifices (F01) into the "B"
ports with the notch facing outward
as shown in Figure 20.
2) Install the orifices (F01) into the "A"
ports with the notch facing inward as
shown in Figure 20.
3) Install the male adapters (F02) into the
ports and tighten to 18 ft-lbs.
Figure 20 – Double Acting Valve Block
Assembly
4.6.1.2 Single Acting Assembly
1) Install the orifices (F01) into the "B"
ports with the notch facing outward as
shown in Figure 21.
2) Install the male adapters (F02) into the
"B" ports and tighten to 18 ft-lbs.
3) Install the plugs (F03) into the "A"
ports and tighten to 18 ft-lbs.

17
Figure 21 – Single Acting Valve Block
4.6.2 Valve Mounting
Figure 22 – Valve Mounting Location
1. Mount the NORAC valve (V01) on the
sprayer using the valve mounting
bracket (B10).
2. As shown in Figure 22, screw short side
of the threaded rods into the bottom of
the valve block at least 3/8". The valve
mounting holes are drilled and tapped
3/8 NC-1" deep.
3. Tighten the Hex nuts to hold the rods.
4. Put the mounting bracket on the other
side of the tube and tighten with the
spring washers and the Hex nuts.
5. Cut excess off of the rods, if necessary.
If using bolts, the bolts should
thread into the valve block at least
3/8". The valve mounting holes
are drilled and tapped 3/8 NC-1"
deep. The rule of thumb for bolt
length is 1-1/2" longer than the
tube size.
The recommended mounting
location is on the rear of the boom
main section and on the vertical
member centered below the Hardi
valve block. Orient the valve
block such that the "A" and "B"
ports face downward.
You must ensure no hydraulic
components will interfere with any
sprayer parts or be pulled tight at
any time.
