1 Lower end of pressure range on some products allows larger droplets which can cause compaction in some soil conditions.

2 Pivot Pressure = pressure at top of mainline at the first outlet (range given is assuming 1300' of 6-5/8" galvanized pipe and < 800

3 Application efficiency = percent of water pumped that reaches the soil surface (may vary significantly depending on actual nozzle pressure and, where applicable, pad selection).

4 SPACING - Senninger recommends a minimum of 150% overlap (nozzles spaced no farther apart than 2/3 of throw radius) for all sprinklers and spray nozzles. In windier conditions, a 200% overlap is preferable. (Exception: The Quad-Spray should be spaced to travel down every other furrow.)
