B. Double Ended Check Valve (Ref# 4) and Clamp (Ref# 2).
C. Fitting (Ref# 17)

valves on both right and left booms. Connect
the check valves together using the

" hose
and hose clamps.
3. Install Raindrop nozzles into nylon 45° elbow. Install nylon elbow into threaded
quickjet caps. Attach caps and gaskets to the check valve. Position Raindrop
nozzles so they point to the rear, and 45° down from horizontal.
4. Fill the tank 1 /

full of water. Place unit on a hard and level surface. Adjust boom
height according to the Nozzle Selection Chart. Turn on spray and observe the
amount of overlapping spray between adjoining nozzles. There should be 100%
overlap. The edge of the spray from one nozzle should reach to the center of the adjoining nozzle. If
required, adjust boom height until the correct overlap is achieved.
Strainers are not supplied with Raindrop nozzles. Use 50 mesh slotted strainers (16-802) on nozzle tips smaller
than standard.
