Figure 1 – System Components and General Location
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 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.
1. On a clean surface remove all plastic
plugs from the NORAC expansion valve
block (V01).
2. Install the 6MBP (F09) into the A port
of the expansion block (Figure 2).
3. Insert the orifice (F08) into the B port of
the expansion block (Figure 2).
4. Install the 6MB 6MOR fitting (F05) into
the B port of the expansion block
(Figure 2).
Figure 2 - Third station expansion block
assembly
5. Remove the three 4MBP plugs from the
UC4+ 2 station valve block.
Figure 3 - 2 Station valve block plug
removal
6. Coat the three o-rings in hydraulic oil
and install them into the expansion
block.

Make sure the o-rings are properly
seated.
Figure 4 - Expansion valve O-ring
placement
7. If this is the only expansion block
attached to the two station valve block,
thread the 4.5” studs into the UC4+
block.
Bolts (3.5”) may be included in
your kit as a substitution for the
studs.
Figure 5 - Expansion valve stud insertion
8. If two expansion blocks are installed, 7”
long studs are provided.
Bolts (6”) may be included in your
kit as a substitution for the studs.
Figure 6 - Attaching two expansion valves
9. Attach the expansion block to the UC4+
block using the included spring washers
and nuts.
10. Tighten the nuts on the studs to 31 ft-lbs
Torque.
Figure 7 - Expansion valve final assembly
11. If the valve block is not already installed
on the sprayer, install it as outlined in
the UC4+ Spray Height Control kit
installation manual.

12. Attach hose H03 to port B on the
expansion block. Route the free end of
the hose (H03) to the John Deere main
lift tee, which is located on the right
hand end of the John Deere valve block
(Figure 8).
Figure 8 - Main Lift Tee Location
13. Disconnect the John Deer main lift tee
and insert the supplied 6FORXR
6MORT tee fitting (F03), shown in
Figure 8.
14. Attach the hose (H03) to the 6FORXR
6MORT tee fitting (F03).
You must ensure no hydraulic
components will interfere with any
sprayer parts or be pulled tight at
any time.

5 ELECTRICAL INSTALLATION
Cable C17 is the only cable
included in the kit.
1. Connect the six pin shroud (T6B) to the
mating tower on the valve extension
cable (previously installed).
2. Connect the three pin tower (T3) to the
mating tower on the valve extension
cable.
Two connectors on C17 will
remain disconnected. These are
used when installing other UC4+
options.
3. Install the two square DIN connectors on
the end of cable C17 to the expansion
block.
The connector marked “Main
Down” goes on the port side of the
block. The connector marked
“Main Up” goes on the non-port
side of the block.

6 COMPLETING THE INSTALLATION
You can now continue to install the
remainder of your UC4+ Spray Height
Control System.
If the system is fully installed then refer to
the UC4+ Operators Manual to run an
Automatic Install with the JD9 type

8 APPENDIX A – VALVE CONNECTOR CHANGE
Starting in January 2009, NORAC is changing the connectors on the boom height control
valve block. The new style valve block will have 2-pin Deutsch connectors on the coils.
The previous models had Hirschman style connectors and the new style valve blocks and
cabling have Deutsch connectors. Your system may ship with either style valve block,
both are functionally equivalent. The system will operate properly with either style of
connector.
