The Industry-Leading Rotor: Achieve Unrivalled Performance with the Hunter PGP Ultra Sprinkler

For decades, the Hunter PGP rotor has stood as the benchmark for reliability and performance in landscape irrigation.

The PGP Ultra takes this legacy to the next level, incorporating over three decades of research, customer feedback, and rigorous testing to deliver a rotor that’s simply the best in its class. Whether you’re a homeowner looking for a dependable sprinkler or a professional requiring top-tier performance, the Hunter PGP Ultra is the ultimate choice for efficient and effective watering.

Unmatched Features and Benefits:

• Patented Automatic Arc Return: Protect your investment from vandalism. If the turret is turned, it automatically returns to its original arc setting, ensuring consistent coverage and preventing water waste.   
• Non-Strippable Drive Mechanism: Say goodbye to stripped gears. This robust, vandal-proof design allows the turret to be turned without causing internal damage, guaranteeing years of reliable operation.   
• Part- and Full-Circle Operation in One Model: Enjoy ultimate flexibility with an adjustable arc ranging from 50° to a full 360° . This eliminates the need to stock multiple rotor types.   
• Extensive Nozzle Options: Fine-tune your watering with a wide selection of standard and low-angle nozzles (typically 8 standard and 4 low-angle included) to suit various landscape needs and optimize water distribution. Optional short-range and high-flow nozzles are also available.   
• Easy Radius Adjustment: A convenient headed and slotted set screw allows for easy radius adjustment of up to 25% using either a Hunter wrench or a standard flat-blade screwdriver.   
• Whisper-Quiet Operation: The gear-driven design ensures a silent rotation, perfect for residential areas and noise-sensitive environments.   
• Improved Dirty Water Tolerance: The internal gear drive is engineered better to withstand debris and sediment in the water supply, enhancing longevity and reducing maintenance.   
• Through-the-Top Arc Adjustment: Make quick and easy arc adjustments, wet or dry, with helpful symbols for intuitive operation.   
• Rubber Cover: A factory-installed rubber cover keeps dirt and debris out of the adjustment components, ensuring smooth operation.   
• Matched Precipitation Rate Nozzles: Achieve even water distribution across your landscape with nozzles designed for matched precipitation.   
• Optional Reclaimed Water Identification: Purple caps are available for easy identification of systems using non-potable water.   
• Optional Drain Check Valve: Prevent low-head drainage and water waste in systems with elevation changes (up to 10 feet with factory-installed valve).

Hunter PGP Ultra Adjustment Instructions
1. Arc Adjustment (Spray Angle)
The arc determines how far the sprinkler head turns (e.g., 90° quarter-circle, 180° half-circle, 360°
full circle).
• To Increase Arc: Insert Hunter adjustment tool (or small flat screwdriver) into the arc adjustment
slot on top. Turn clockwise (up to 360°).
• To Decrease Arc: Turn counter-clockwise (minimum 50°).

Tip: Always start with the left-hand stop fixed before setting arc.

2. Radius Adjustment (Spray Distance)
Insert the adjustment tool into the radius adjustment screw above the nozzle. This screw also acts
as the nozzle retaining screw, holding the nozzle securely in place.
• Turn clockwise to decrease distance (the screw lowers into the water stream).
• Turn counter-clockwise to increase distance (up to full nozzle radius).

Note: The radius is also determined by the nozzle size you use, your water flow and pressure.
Additionally, tipping the spray at the nozzle can be done with any nozzle to fine-tune the distance.

3. Nozzle Installation or Change
1. Use tool to pull riser stem up and hold in place.
2. Remove existing nozzle (if fitted).
3. Insert desired nozzle firmly into nozzle socket.
4. Tighten the radius adjustment screw (nozzle retaining screw) slightly to lock nozzle.
4. Flushing Before Setup

Before installing a nozzle, briefly turn system on to flush debris. This prevents clogging
