5. Setup and Installation
Follow these steps to replace an existing solenoid or install a new one. Ensure all safety precautions are observed.
- Disconnect Power: Locate your irrigation controller and turn off the power to the entire system or the specific zone you are working on. This is crucial to prevent electrical shock.
- Locate Valve: Identify the irrigation valve where the solenoid needs to be replaced.
- Remove Old Solenoid:
- Carefully disconnect the two wires leading to the old solenoid. Note which wire connects to the common and which to the zone wire, if distinguishable.
- Unscrew the old solenoid from the valve body by turning it counter-clockwise. Water may escape from the valve once the solenoid is removed.
- Inspect the valve body for any remaining O-rings or plastic pieces from the old solenoid. Remove them to ensure a clean seating surface for the new solenoid. Some older Rain Bird or Richdel valves may require removing a plastic protrusion from the bottom of the new solenoid for proper fit.
- Prepare New Solenoid: If necessary, and only if it obstructs proper seating in your specific valve model, carefully trim any excess plastic from the bottom of the new Irritrol R811 solenoid.
- Install New Solenoid:
- Thread the new Irritrol R811-24VACG solenoid into the valve body by turning it clockwise. Hand-tighten until snug. Do not overtighten, as this can damage the valve body or solenoid.
- Connect the two wires from the irrigation system to the two wires of the new solenoid. It is generally not polarity-sensitive for AC solenoids, but ensure connections are secure. Use waterproof wire connectors (e.g., grease caps) to protect the connections from moisture and corrosion.
- Test System: Restore power to the irrigation controller. Manually activate the zone associated with the newly installed solenoid to check for proper operation and any leaks.
6. Operation
The Irritrol R811-24VACG solenoid functions as an electromagnetic switch that controls the flow of water through an irrigation valve. When the irrigation controller sends a 24VAC electrical signal to the solenoid, it creates a magnetic field that lifts a plunger, opening a pilot port within the valve. This action releases pressure from the diaphragm, allowing the main valve to open and water to flow to the sprinkler zone. When the electrical signal is removed, the magnetic field collapses, the plunger returns to its resting position, and the valve closes, stopping water flow.
The solenoid's operation is entirely dependent on the electrical signals from your irrigation controller. Ensure your controller is programmed correctly for desired watering schedules.
7. Maintenance
The Irritrol R811-24VACG solenoid is designed for durability and typically requires minimal maintenance. However, periodic checks can help ensure long-term performance:
- Inspect Wiring: Annually check wire connections for corrosion or damage. Ensure waterproof connectors are intact and sealed.
- Check for Leaks: Periodically inspect the area around the valve and solenoid for any signs of water leaks. A leak might indicate an issue with the solenoid's seating or the valve diaphragm.
- Debris Removal: If the valve is exposed to significant debris, occasionally remove the solenoid and flush the valve body to clear any obstructions that might affect plunger movement.
8. Troubleshooting
If your irrigation zone is not operating correctly after solenoid replacement, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open (no water flow) |
|
|
| Valve does not close (continuous water flow) |
|
|
| Intermittent operation |
|
