4.7.3 Hydraulic Plumbing – Electrically
Teed
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
4.
2. Tee in pressure (“P”) and tank (“T”)
lines to the NORAC valve block.
3. The existing hoses that run to the boom
tilt cylinders should be disconnected
from the sprayer valve block and
reconnected to the NORAC valve
block.
a) The raise lines from the boom tilt
cylinders must be connected to the
“B” ports of the NORAC valve block.
The ports on the sprayer block must
then be plugged/capped.
b) If the sprayer is Dual Acting, the “A”
ports of the NORAC block must be
connected to the “lower” lines of the
cylinders. The ports on the sprayer
block must then be plugged/capped.
c) If the sprayer is Single Acting, the “A”
ports on the NORAC block are
plugged. The lower lines of the
cylinders can remain attached to the
sprayer valve block.

1. Follow Figure 7 to plumb the hydraulic
components.
2. Tee in the pressure (“P”) and tank (“T”)

3. The existing hoses that run to the boom
tilt cylinders should be disconnected
from the sprayer valve block and teed
into the NORAC valve block.
4. The “raise” lines from the boom tilt
cylinders must be connected to the “B”
ports of the NORAC valve block.
a) If the sprayer is Dual Acting, the “A”
ports of the NORAC block must be
connected to the “lower” lines of the
