NSTALLATION
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+ 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 17).
2. Install the orifices (F05) into the "B"
ports with the notch facing outward
as shown in Figure 18. An O-ring pick
can be used to ease installing the
orifices into their locations.

3. Install the 6MB-6MJ fittings (F02) into
the "B" ports and tighten to 18 ft-lbs.
4. Install the 6MBP plugs (F04) into the
"A" ports and tighten to 18 ft-lbs.

5. Mount the NORAC valve (V01) on the
sprayer using the valve mounting
bracket (B10). 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.
The recommended location for
the NORAC valve is on the rear
of the sprayer just left of the
Summers valve block on the
horizontal cross brace. Orient
the NORAC valve block so “A”
and “B” ports face forward.
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.
