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 F UNCTIONALITY C HECK
Before beginning the install, ensure all manual hydraulic boom functions are operating properly
on the sprayer.
oAll fold functions
oMain lift function
oWing tilt functions (if applicable)
oSlant function
4.2 E XISTING SYSTEM CHECK
oEnsure the boom suspension is configured as a short-pendulum (insert boom pin to
constrain the long-pendulum suspension)
oInspect boom suspension wear-pads for excessive wear
oSet the boom suspension to be critically damped (Figure 3). Adjust the boom springs and
dampers accordingly.
A) Unlock the boom, 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.
Figure 3: Boom push test- critically damped

oAdjust the slant speed of the boom until the full stroke (from full counter-clockwise to
full clockwise) is 6 seconds (Figure 4). This is the time required for the slant cylinder to
travel from fully extended to fully retracted, or vice-versa.
Figure 4: Setting the slant speed
6 seconds

4.3 W ING SENSOR INSTALLATION
1. Assemble the breakaway sensor mounting Brackets (B11) as show in Figure 5.
Figure 5 – Breakaway sensor 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. Refer to the following sections for specific details
on mounting to different styles of booms.
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.
