4.6.2 Valve Mounting
1. Mount the NORAC valve (V01) on the
sprayer using the valve mounting
bracket (B10).
2. As shown in Figure 20, screw short
side of the threaded rods into the
bottom of the valve block at least 3/8".
The valve mounting holes are drilled and
tapped 3/8 NC-1" deep.
3. Tighten the Hex nuts to hold the rods.
4. Put the mounting bracket on the other
side of the tube and tighten with the
spring washers and the Hex nuts.
5. Cut excess off of the rods, if necessary.
If using bolts, 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.
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.

4.6.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
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.
2. The “B” ports leading from the NORAC
valve block are the “raise” lines (H01),
and must be connected to the boom
raise cylinders via the existing lines and
the “T” fittings (F04) provided, as
illustrated. The “T” fittings are inserted
into the REDBALL hydraulic circuit to
allow the NORAC Valve block to
control the cylinders in parallel with the
existing system.
3. Tee the pressure and tank (H03) lines
for the NORAC block in to the existing
lines from the REDBALL valve block,
using the “T” fitting (F04).
You must also ensure there are
no other orifices present in the
circuit between the NORAC
valve block and the boom
cylinders.
