8.4 Hydraulic Plumbing: Electrically Teed Installation
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the NORAC valve is mounted, the hydraulic hoses and fittings can be plumbed. The
plumbing for the hydraulic circuit is shown schematically in Figure 5.
2. Disconnect the pressure and tank lines from the sprayer valve block and insert the two tees
(*F01) between the hoses and the valve block.
3. Connect two hydraulic hoses (*H01) from the free ends of the tees to the pressure and
tank port on the NORAC valve block.
4. Disconnect the existing boom tilt cylinder “raise” hoses from the sprayer valve block. Plug
the ports on the sprayer valve block (*F02). Connect the boom tilt cylinder hoses to the
ports on the NORAC valve block. The “raise” lines must be connected to the “B” ports.
5. If the sprayer is dual acting, disconnect the existing boom tilt cylinder “lower” hoses from
the sprayer valve block. Plug the ports on the sprayer valve block (*F02). Connect the
boom tilt cylinder hoses to the ports on the NORAC valve block. The “lower” lines must
be connected to the “B” ports.
6. If the sprayer is single acting, the “lower” lines remain connected to the sprayer valve block
and the “A” ports on the NORAC block are plugged (F08).
