Introduction
This manual provides essential instructions for the installation, operation, and maintenance of your Hunter 9V DC Latching Solenoid. This component is designed for use in battery-operated irrigation systems, providing reliable valve control. Please read this manual thoroughly before installation and retain it for future reference.
Safety Information
- Always disconnect power to the irrigation controller or battery pack before performing any installation or maintenance.
- Ensure all electrical connections are secure and protected from moisture to prevent short circuits.
- Do not attempt to modify the solenoid. Unauthorized modifications can lead to malfunction and void the warranty.
- Keep the solenoid and wiring away from sharp objects or excessive heat sources.
Setup and Installation
The Hunter 9V DC Latching Solenoid is designed for straightforward installation into compatible irrigation valves. Follow these steps for proper setup:
- Prepare the Valve: Ensure the irrigation valve is clean and free of debris. If replacing an existing solenoid, carefully unscrew and remove the old unit.
- Install the Solenoid: Screw the new 9V DC Latching Solenoid into the valve's solenoid port by hand until it is finger-tight. Do not overtighten, as this can damage the valve or solenoid.
- Connect Wiring: The solenoid features two wires (typically red and black). Connect these wires to the corresponding terminals on your battery-operated irrigation controller or module. Refer to your controller's manual for specific wiring diagrams. Ensure connections are secure and insulated.
- Test the System: After installation, activate the valve manually or through your controller to ensure proper operation (opening and closing). Check for any leaks around the solenoid connection.

Operating Instructions
The 9V DC Latching Solenoid operates in conjunction with a compatible battery-powered irrigation controller. It uses a momentary electrical pulse to switch the valve between open and closed states, conserving battery power.
- Automatic Operation: Once connected to a compatible controller, the solenoid will receive signals to open and close the valve according to the programmed irrigation schedule.
- Manual Operation: Most valves equipped with this solenoid allow for manual operation. Typically, this involves turning a lever or knob on the valve itself. Refer to your valve's specific instructions for manual override procedures.
Maintenance
Regular maintenance ensures the longevity and reliable performance of your solenoid and irrigation system.
- Battery Check: If your system uses a separate battery pack for the controller, ensure the batteries are fresh and properly installed. A weak battery can prevent the solenoid from fully opening or closing the valve.
- Wiring Inspection: Periodically inspect the wiring for any signs of damage, fraying, or corrosion. Repair or replace damaged wiring promptly.
- Debris Removal: Ensure the area around the solenoid and valve is clear of dirt, mud, or plant growth that could impede operation or cause damage.
- Winterization: In cold climates, follow proper winterization procedures for your entire irrigation system, which may include removing the solenoid or draining the valve to prevent freeze damage.
Troubleshooting
If you experience issues with your Hunter 9V DC Latching Solenoid, consider the following common troubleshooting steps:
- Valve Not Opening/Closing:
- Check the battery in your controller. Replace if low or dead.
- Verify all wiring connections are secure and free of corrosion.
- Ensure the solenoid is screwed in finger-tight to the valve.
- Check for debris obstructing the valve diaphragm or solenoid plunger.
- Confirm the controller is sending a signal to the correct zone.
- Constant Water Flow:
- The valve may be stuck open due to debris. Manually cycle the valve or disassemble and clean the valve diaphragm.
- The solenoid may be faulty and not returning to its closed position.
- No Response from Controller:
- Ensure the controller's battery is charged.
- Check the wiring from the controller to the solenoid for breaks or loose connections.
