How do I adjust my Hunter MP Rotator's radius and arc?
To achieve optimal results, replace all sprinklers on a zone with MP Rotators and adjust the run time accordingly. The precipitation rate of the MP Rotator is much lower than sprays and operating times will be similar to stream rotor zones.
A consistent operating pressure greater than > 55 PSI (3.7 BAR) shortens the life of the sprinkler, increases rotation speed, reduces sprinkler uniformity and voids the trade warranty.
