Manifold Option
Refer to Figure 2-4.
1. From Figure 2-5 on the next page, determine combi-
nation of tubing sections needed for your manifold
based on hitch width and tine spacing. Connect sec-
tions with threaded tee fittings (1) or pipe couplers (2)
as indicated on Figure 2-5. Cap ends of tubing with
caps (3).
2. Install hangers (4) to the coulter bar with u-bolts.
Place hangers where necessary. Use at least one
hanger per tubing section.
3. Mount manifold on hangers. At each hanger, use a
bolt (5) and nut (6) to secure base of nozzle body (7)
to hanger. Assemble other half of nozzle body (8)
around manifold.
4. Install a nozzle body over all remaining holes in man-
ifold.
5. In each nozzle body, install an orifice plate (9). Place a
nozzle cap (10) over nozzle body and turn cap clock-
wise to secure nozzle cap on nozzle body.
NOTE: On 8-, 10-, and 15-inch nozzle spacings, you must
plug some nozzles. Refer to chart to determine where to
install nozzle caps (11) instead of quick caps.
6. Install threaded/hose barb adaptors (12) in quick
caps.
7. Plumb manifold. Install an elbow (13) in tee fittings.
Cut 3/4-inch-diameter hose in half. Connect 3/4-inch
hose (14) to elbows on manifold and to hose barb tee
fitting (15). Use 1-inch-diameter hose (16) to connect
tee fitting to pump outlet fitting.
