Orbit 100 Series Anti-Siphon Automatic Sprinkler Valve

Introduction

This manual provides instructions for the installation, operation, and maintenance of the Orbit 100 Series Anti-Siphon Automatic Sprinkler Valve. This valve is designed to prevent back-flush and contaminants from entering your household water supply, ensuring the safety of your irrigation system.

The durable, non-corrosive plastic construction ensures reliable performance. It is compatible with standard 24-Volt residential sprinkler systems and includes a manual on/off option and bleed screw for convenient testing and flushing.

Key Features

• Backflow Prevention: Incorporates an atmospheric vacuum breaker to protect your irrigation and culinary water systems from contamination.
• Reliable Operation: Ensures water flows in one direction, preventing siphoning and backflow.
• Easy Installation: Designed for above-ground installation on risers.
• Integrated Scrubber Filter: Helps prevent clogs and simplifies maintenance.
• Manual Control: Features a manual on/off option and bleed screw for system testing and flushing.

Setup and Installation

The Orbit 100 Series Anti-Siphon Automatic Sprinkler Valve is designed for above-ground installation. Ensure proper plumbing practices are followed to prevent leaks and ensure optimal performance.

1. Identify Location: Select an appropriate location for the valve, ensuring it is installed above ground on risers as required for anti-siphon devices.
2. Prepare Piping: Ensure the incoming water line and outgoing sprinkler line are properly prepared with 3/4" FPT (Female Pipe Thread) connections.
3. Connect Valve: Thread the valve onto the prepared piping. Ensure the flow arrow on the valve body points in the direction of water flow towards the sprinkler system. Hand-tighten, then use a wrench for a final quarter-turn, avoiding overtightening.
4. Wire to Controller: Connect the valve's electrical wires to your 24-Volt residential sprinkler system controller. Refer to your controller's manual for specific wiring instructions.
5. Test System: After installation, slowly turn on the main water supply and check for leaks. Proceed to the Operating Instructions section for testing the valve.

Operating Instructions

The valve can be operated automatically via your sprinkler controller or manually for testing and flushing.

Automatic Operation

Once wired to a 24-Volt sprinkler controller, the valve will open and close according to the programmed schedule. Ensure the manual on/off lever is in the 'OFF' position for automatic control.

Manual Operation

For testing or flushing the system, you can manually operate the valve:

• Manual On/Off Lever: Locate the small lever on the solenoid. Move the lever to the 'ON' position to manually open the valve and allow water flow. Move it to the 'OFF' position to close the valve.
• Bleed Screw: To manually open the valve and flush out debris, slowly turn the bleed screw counter-clockwise until water begins to flow. To close the valve, turn the bleed screw clockwise until it is snug. Do not overtighten.

Maintenance

Regular maintenance ensures the longevity and proper function of your anti-siphon valve.

• Scrubber Filter: The valve features an integrated scrubber filter designed to prevent clogs. Periodically inspect and clean this filter, especially if you notice reduced water flow or inconsistent operation. To clean, turn off the main water supply, unscrew the top of the valve, remove the filter, rinse it thoroughly, and reassemble.
• Leak Inspection: Regularly check for any signs of leaks around the valve body or connections. Address any leaks promptly to prevent water waste and potential damage.
• Winterization: In regions subject to freezing temperatures, ensure the valve and entire irrigation system are properly winterized to prevent freeze damage. Consult local guidelines for specific winterization procedures.

Troubleshooting

If you encounter issues with your Orbit Anti-Siphon Automatic Sprinkler Valve, refer to the following common troubleshooting steps:

• Valve Does Not Open:
  • Check if the main water supply is on.
  • Verify electrical connections to the controller and valve solenoid.
  • Ensure the controller is programmed correctly and sending power to the valve.
  • Manually open the valve using the bleed screw or manual on/off lever to check for water flow. If water flows, the issue may be electrical.
• Valve Does Not Close:
  • Check if the manual on/off lever is in the 'OFF' position.
  • Ensure the bleed screw is fully tightened (do not overtighten).
  • Inspect the valve for debris lodged in the diaphragm or seat. Turn off water, disassemble, clean, and reassemble.
  • Check for proper electrical signal from the controller to ensure it's not continuously sending an 'open' signal.
• Low Water Flow:
  • Inspect and clean the integrated scrubber filter for clogs.
  • Check for obstructions in the piping leading to or from the valve.
  • Ensure the main water supply pressure is adequate.
• Leaks from Valve:
  • Check all threaded connections for proper sealing and tightness.
  • Inspect the valve body for cracks or damage.
  • Ensure the top cap is securely fastened and the diaphragm is correctly seated.
