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

*Some sprayers may not have this function.
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 1through 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 4.7, 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 4 and
Figure 5.
Figure 4 – Breakaway Sensor Bracket
Exploded View
Figure 5 – 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 8) or in front of the tube (Figure
6).
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 6 and Figure 8).
When installing the UC4+ sensors
(E02), start with the smallest serial

10
number on the left hand side
proceeding to the largest serial
number on the right hand side
(Figure 11).
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 6).
Figure 6 – Another Acceptable Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown in
Figure 7.
Figure 7 – 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 ROLL SENSOR INSTALLATION
For this installation, the roll sensor is
only being used for temperature
compensation.
1. Mount the roll sensor to the provided roll
sensor bracket.
Figure 12 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
2. Attach the roll sensor and roll sensor bracket
to the boom, near the NORAC valve block
using the provided cable ties.
3. Attach the temperature probe on the roll
sensor to the side of the NORAC valve
block, using the provided 3/8” bolt.

4.5 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.
4.5.1 Valve Assembly
1. On a clean surface remove all plastic plugs
from the NORAC hydraulic Valve (V01)
(Figure 14).
Figure 14 – NORAC Valve Block
2. Install the orifices (F05) into the "B" ports
with the notch facing outward as shown
in Figure 15. An O-ring pick can be used
to ease installing the orifices into their
locations.
3. Install the orifices (F05) into the "A" ports
with the notch facing inward.
4. Install the 6MB-6MJ fittings (F03) into the
“A” and “B” ports and tighten to 18 ft-lbs.
Figure 15 – Valve Block Assembly

14
4.5.2 Valve Mounting
1. Mount the NORAC valve (V01) on the
sprayer using the valve mounting bracket.
2. 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.
You must ensure no hydraulic
components will interfere with any
sprayer parts or be pulled tight at
any time.
Figure 16 – Valve Mounting Example

4.5.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
1. After the NORAC valves are mounted, the
hydraulic hoses and fittings can be plumbed.
The plumbing for the hydraulic circuit is
shown schematically in Figure 3.
2. Lower the wings to relieve holding pressure.
3. Disconnect the junction of the steel
hydraulic line and the hose of the
SpraCoupe circuit. Connect a 6FJXR 6MJT
tee fitting (F02) between the steel line and
the hose (Figure 18).
4. Connect the 90 degree fittings of hoses H02
to the “A” and “B” ports of the NORAC
block (Figure 17). Route hoses H02 from
the NORAC valve block to the tee fittings
(F02) (Figure 18).
5. The “B” ports leading from the NORAC
valve block are the “raise” lines, and must be
connected to the boom raise cylinders via
the existing lines and the tee fittings (Figure
18).
6. The “A” ports leading from the NORAC
valve block are the “lower” lines, and must
be connected to the boom lower cylinders
via the existing lines and the tee fitting
(Figure 18).
7. Connect the 90 degree end of hoses H03 to
the Tank and Pressure ports of the NORAC
valve block (Figure 17) (NOTE: This end of
the hose has an adapter fitting already
installed.). Route hoses H03 to the
SpraCoupe valve block.
8. Remove the existing SpraCoupe Pressure
line from between the SpraCoupe valve
block and tee.
9. Connect the hose (H03) from the NORAC
Tank line to the Pressure port on the
SpraCoupe valve block using an 8FJ 6MJ
fitting (F04) (Figure 19).
10. Connect the hose (H03) from the NORAC
Pressure line to the SpraCoupe Pressure tee
using an 8FJ 6MJ fitting (F04) (Figure 19).

4.6 ELECTRICAL INSTALLATION
1. Install the UC4+ Control Panel (E01) in the
cab of the sprayer. Mount the panel where
it will be clearly visible and within easy reach
of the operator.
A good spot to mount the UC4+ control
panel is on the right hand side of the cab to
the Roll Over Protection Bar (ROP). Four
pilot holes for the screws provided need to
be drilled to facilitate the control panel
mounting.
Another option is to purchase an adapter
for the flexible panel mount that has a 3/8"
NC threaded stud on the end to bolt
through an existing mount. You can find
these at your local outdoor store as a RAM
mount part number RAM-B-236. (See
http://www.ram-mount.com/)
