4.5.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
After the NORAC valves are mounted, the
hydraulic hoses and fittings can be plumbed.
The kit is designed to work with either
single acting or double acting hydraulic
circuits. The plumbing for the typical
hydraulic circuit is shown in Figure 3 and
Figure 4.
4.5.3.1 Double Acting Plumbing
1. Attach 1/2 inch pressure ("P") and tank
("T") lines to the NORAC valve block.
2. The existing hoses that run to the boom
tilt cylinders should be disconnected
from the sprayer valve block and teed in
to the NORAC valve block.
a) The “raise” lines from the side of
the cylinders, which raise the
booms, must be connected (in
parallel) to the “B” ports of the
NORAC block.
b) The “lower” lines from the side of
the cylinders, which lower the
booms, must be connected (in
parallel) to the “A” ports of the
NORAC block.
4.5.3.2 Single Acting Plumbing
1. Attach 1/2 inch pressure ("P") and tank
("T") lines to the NORAC valve block.
2. The existing hoses that run to the boom
tilt cylinders should be disconnected
from the sprayer valve block and teed in
to the NORAC valve block.
a) The “raise” lines from the side of
the cylinders, which raise the
booms, must be connected (in
parallel) to the “B” ports of the
NORAC block.
b) The “A” ports on the NORAC
block are plugged. The “lower”
lines of the cylinders can remain
attached to the sprayer valve block.
