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.

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.
