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.

WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
You must also ensure there are no
other orifices present in the circuit
between the NORAC valve block
and the boom cylinders.
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 “raise” lines from the side of the
boom tilt cylinders, must be connected
to the “B” ports of the NORAC valve
block via the existing lines and the
6FJXR-6MJT fittings (F03) provided.
The 6FJXR-6MJT fittings are also mated
with the original Summers’ valve block.
3. NORAC supplies two new hydraulic
hoses (H03) to run to F03. Route the
lines from the NORAC valve block to
the Summers’ valve block and “tee” into
F03 as shown in Figure 3.
4. Connect the two remaining hoses (Item
H02) to the Pressure (P) and Tank (T)
ports on the NORAC valve block (V01).
Route both of these lines to the sprayer’s
hitch for connection with the tractor’s
pressure and tank fittings.
