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.

2. Connect H2 to the pressure ("P") and

tank ("T") ports on the NORAC valve
block.

3. The existing hoses that run between the

boom tilt cylinders and the sprayer valve
block should be removed.

If the sprayer is Single Acting,

the "A" ports on the NORAC
block are plugged (Section

4.6.1.2). The “lower” lines of the
cylinders can remain attached to
the sprayer valve block.

4. The “raise” lines must be connected to

the "B" ports of the NORAC valve
block. The ports on the sprayer block
must then be capped.

5. If the sprayer is Double Acting, the "A"

ports of the NORAC block must be
connected to the “lower” lines of the
cylinders.
