Hunter PGP12CV PGP Ultra Pop-Up Sprinkler User Manual

Introduction

This manual provides comprehensive instructions for the installation, operation, maintenance, and troubleshooting of the Hunter PGP12CV PGP Ultra Pop-Up Sprinkler with Check Valve, 12-Inch. The PGP Ultra is designed for efficient and reliable landscape irrigation. Please read these instructions carefully before installation and operation to ensure optimal performance and longevity of your sprinkler system.

Product Overview

The Hunter PGP Ultra is a pop-up rotor sprinkler featuring a check valve to prevent low-head drainage. It incorporates a non-strippable drive and automatic arc return for enhanced durability and functionality. This model is 12 inches in height and comes with a selection of nozzles to accommodate various watering requirements.

Setup and Installation

1. Site Preparation: Excavate a trench from the main water line to the desired sprinkler location. Ensure the trench is deep enough to allow the sprinkler to be installed flush with the ground surface when retracted.
2. Connecting to Water Supply: Connect the sprinkler to the irrigation piping using appropriate fittings. Ensure all connections are watertight to prevent leaks.
3. Sprinkler Installation: Place the sprinkler in the excavated hole. The top of the sprinkler body should be level with the finished grade to allow for proper pop-up and retraction. Backfill the trench, compacting the soil around the sprinkler.
4. Nozzle Installation:
   • Use the white end of the Hunter adjustment tool (included) to pull up the sprinkler riser.
   • Insert the desired PGP Ultra nozzle into the nozzle socket. Note that only PGP Ultra nozzles are compatible with this model.
   • Push the nozzle firmly into place. Some users find it helpful to insert the nozzle at a two o'clock position and turn counter-clockwise to 12 o'clock for full insertion.
5. Radius and Arc Adjustment:
   • Arc Adjustment: Use the Hunter adjustment tool to rotate the arc adjustment screw. Turning clockwise increases the arc, and counter-clockwise decreases it. The sprinkler has an automatic arc return feature.
   • Radius Adjustment: The radius can be reduced by turning the radius reduction screw clockwise. Do not reduce the radius by more than 25% of the nozzle's rated radius.

Operating Instructions

Once installed and adjusted, the Hunter PGP12CV sprinkler operates automatically as part of your irrigation system. When water pressure is applied, the riser will pop up, and the sprinkler will begin rotating to distribute water over the set arc and radius.

• Water Pressure: Ensure your system operates within the recommended water pressure range for optimal performance. Refer to the nozzle performance specifications available on the Hunter website for detailed flow rates and pressure requirements for your chosen nozzle.
• Seasonal Adjustments: Periodically check and adjust the arc and radius settings as your landscape matures or seasonal watering needs change.

Maintenance

Regular maintenance ensures the longevity and efficient operation of your PGP Ultra sprinkler.

• Filter Screen Cleaning: Periodically remove the sprinkler riser and clean the filter screen located at the base of the riser. Debris can accumulate and restrict water flow.
• Nozzle Inspection: Check nozzles for any blockages or damage. Replace damaged nozzles to maintain proper spray patterns.
• Check for Obstructions: Ensure no vegetation or debris is impeding the sprinkler's pop-up or spray pattern. Tree roots can sometimes interfere with buried components.
• Winterization: In regions subject to freezing temperatures, properly winterize your irrigation system to prevent damage. This typically involves draining the system or using compressed air to blow out water from the lines and sprinklers.
• Pop-Up and Retraction: Verify that the sprinkler pops up fully when the system is active and retracts completely when the system is off. A sprinkler that does not retract fully can be a tripping hazard and is susceptible to damage.

Troubleshooting

This section addresses common issues you might encounter with your PGP Ultra sprinkler.

• Sprinkler Not Popping Up or Retracting:
  • Low Water Pressure: Check the system's water pressure. Insufficient pressure can prevent full pop-up.
  • Debris: Inspect the area around the sprinkler for soil, grass, or other debris that might be obstructing the riser. Clean the filter screen.
  • Damaged Riser: If the riser is physically damaged, it may need replacement.
• Uneven Spray Pattern or No Water:
  • Clogged Nozzle/Filter: Remove and clean the nozzle and filter screen.
  • Incorrect Nozzle: Ensure the correct nozzle is installed and properly seated.
  • Low Pressure: Verify adequate water pressure to the sprinkler.
• Water Leaking from Sprinkler Base:
  • Loose Connection: Check the connection to the water supply line for tightness.
  • Damaged Seal: Internal seals may be damaged, requiring replacement of the sprinkler head.
• Sprinkler Gets Stuck After Popping Up:
  • Debris: Clear any debris around the riser that might be preventing it from retracting.
  • Internal Issue: If the issue persists, the internal mechanism may be faulty, and the sprinkler might need replacement.
