1. Introduction
This manual provides instructions for the installation, operation, and maintenance of the Rain Bird SRKCP/CPF Replacement Solenoid. This solenoid is designed to restore functionality to compatible Rain Bird irrigation valves, ensuring efficient and reliable water flow control.
The SRKCP/CPF solenoid is an energy-efficient, low-power encapsulated unit featuring a captured plunger for enhanced durability and long-term performance. It is engineered for straightforward removal and installation, often requiring no specialized tools.
2. Compatibility
The Rain Bird SRKCP/CPF Replacement Solenoid is compatible with the following Rain Bird valve series:
- APAS Series Valves
- ASVF Series Valves
- ECV Series Valves
- CP Series Valves
- CPF Series Valves
- DV Series Valves
- DAS Series Valves
- JTV Series Valves
Important Note:
This replacement solenoid is designed exclusively for newer Rain Bird valves featuring a hexagon-shaped solenoid. It is not compatible with older Rain Bird valves that utilize round solenoids with ridges.
3. Key Features
- Direct replacement for specified Rain Bird valve models.
- Energy-efficient, low-power encapsulated design.
- Features a captured plunger for extended life and reliability.
- Designed for quick and easy installation without the need for special tools.
- Helps in efficient troubleshooting and repair of irrigation systems.
4. Installation
Follow these steps to replace the solenoid on your compatible Rain Bird valve:
- Turn off Water Supply: Before beginning, ensure the main water supply to the irrigation system is completely shut off to prevent water leakage.
- Locate the Valve: Identify the valve requiring solenoid replacement. It is typically located within a valve box in your landscape.
- Disconnect Wiring: Carefully disconnect the two wires connected to the existing solenoid. Note which wire connects to which terminal if applicable, though for a solenoid, polarity is generally not an issue.
- Remove Old Solenoid: Unscrew the old solenoid from the valve body by turning it counter-clockwise. This can usually be done by hand or with minimal force.
- Inspect Valve: Briefly inspect the valve port for any debris or damage before installing the new solenoid.
- Install New Solenoid: Screw the new Rain Bird SRKCP/CPF solenoid into the valve body by turning it clockwise until it is hand-tight. Do not overtighten.
- Connect Wiring: Reconnect the two wires to the new solenoid. Ensure a secure connection. Wire nuts are commonly used for this purpose.
- Restore Water Supply: Slowly turn the main water supply back on. Check for any leaks around the newly installed solenoid.
- Test Operation: Test the valve operation using your irrigation controller to ensure it opens and closes correctly.
5. Operation
The SRKCP/CPF solenoid primarily operates electronically via your irrigation controller. However, it also features a manual override option:
- Automatic Operation: When connected to an irrigation controller, the solenoid will open and close the valve based on the programmed schedule.
- Manual Operation: The solenoid body includes markings for "ON" and "OFF" with an arrow indicating "MANUAL 1/4 TURN". To manually open the valve, turn the solenoid 1/4 turn counter-clockwise towards the "ON" position. To close the valve manually, turn it 1/4 turn clockwise towards the "OFF" position. This feature is useful for testing or temporary watering without the controller.
6. Maintenance
The Rain Bird SRKCP/CPF Replacement Solenoid is designed for minimal maintenance. As a replacement part, its primary function is to restore valve operation. Regular maintenance involves:
- Leak Inspection: Periodically check the valve area for any signs of water leakage, which could indicate a faulty seal or an issue with the solenoid or valve body.
- Debris Removal: Ensure the valve box remains clear of excessive dirt or debris that could interfere with valve or solenoid function.
- Wiring Integrity: Occasionally inspect the wiring connections for corrosion or damage, ensuring they remain secure.
7. Troubleshooting
If your irrigation valve is not functioning correctly after solenoid replacement, consider the following:
- Valve Not Opening:
- Verify the water supply is fully open.
- Check electrical connections to the solenoid for looseness or corrosion.
- Ensure the irrigation controller is sending power to the correct zone.
- Manually turn the solenoid 1/4 turn to the "ON" position. If the valve opens, the electrical signal or solenoid itself may be faulty.
- Valve Not Closing:
- Manually turn the solenoid 1/4 turn to the "OFF" position. If the valve closes, the electrical signal from the controller might be stuck "ON".
- Inspect the valve diaphragm for debris or damage that prevents it from seating properly.
- Ensure the solenoid is fully tightened and not cross-threaded.
- Incorrect Solenoid Type: Double-check that the installed solenoid is the correct hexagon-shaped replacement for your valve model. Older round solenoids are not compatible.
