4 INSTALLATION PROCEDURE
4.1 E XISTING 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 B OOM S PEED T EST
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 5 for the RIGHT,
and MAIN 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 4.8, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.

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.
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.
Figure 5 - Acceptable Mounting
Please refer to the UC4+ Spray Height
Control system warranty at the end of
the UC4+ Spray Height Control
Operator’s Manual (M01) for

(ahead) of the boom (Figure 5 and
Figure 7).
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 8).
4. 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).

4.6 H YDRAULIC I NSTALLATION
If your sprayer has a valve block
with serial number 21.12732 or lower
then you must refer to Section 6 to
complete the hydraulic plumbing.
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 Mounting
1. On a clean surface remove all plastic
plugs from the NORAC hydraulic Valve
(V01) (Figure 13).

WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
When changing the boom hydraulic
hoses, leave the booms in the
TRANSPORT POSITION.
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.
Do NOT remove the fittings
installed in the NORAC valve
block in Section Error! Reference
source not found.. Any adapting
required must be done after these
components.
2. Remove the sprayer’s boom raise lines
from the cylinders and valve block.
The raise lines are located on the
rod end of the cylinder.
3. Use the 8MBP plug (F09) to cap the
sprayer’s valve block where the two
hoses were removed.
4. Use hoses H08 and H06 to connect the
raise side of the cylinders to the NORAC

4.7 E LECTRICAL I NSTALLATION
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.
