2. Safety Information
- Always disconnect power to the irrigation controller before installing or servicing the solenoid valve.
- Ensure all electrical connections are waterproof and comply with local electrical codes.
- Do not exceed the maximum operating pressure of 12 bar (174 psi).
- Install the valve in a location protected from freezing temperatures.
- Use appropriate tools for installation to avoid damaging the valve or piping.
3. Package Contents
Verify that all components are present before beginning installation:
- 1 x Claber 90814 24V Solenoid Valve
4. Setup and Installation
- Prepare the Location: Choose a suitable location for the valve, typically within a valve box, ensuring it is accessible for maintenance and protected from direct sunlight or extreme weather.
- Connect Piping: The valve features 1" female inlet and outlet threads. Apply PTFE tape or pipe sealant to the male threads of your irrigation pipes. Connect the inlet pipe to the side marked 'IN' or with an arrow indicating flow direction, and the outlet pipe to the other side. Hand-tighten, then use a wrench for a final quarter to half turn, avoiding over-tightening.
- Electrical Connection: Connect the two wires from the solenoid to the corresponding 24V AC output terminals on your irrigation programmer. Ensure a secure, waterproof connection using appropriate connectors (e.g., waterproof wire nuts). This valve is compatible with any 24V AC multi-line programmer.
- Test for Leaks: Before burying the valve, slowly turn on the main water supply and check for any leaks at the connections.
- Manual Operation Check: The valve is equipped with a manual open/close device. Turn the manual override lever or screw to the 'OPEN' position to allow water flow, then return it to 'CLOSE' to stop flow. This confirms the valve's mechanical function.
5. Operating Instructions
The Claber 90814 solenoid valve operates automatically in conjunction with a 24V AC irrigation programmer.
- Automatic Operation: Once connected to a compatible 24V AC programmer, the valve will open and close according to the schedule set on the programmer. When the programmer sends a 24V AC signal, the solenoid activates, opening the valve. When the signal is removed, the valve closes.
- Manual Operation: In case of power outage or for testing purposes, you can manually open and close the valve using the integrated manual override mechanism. Locate the lever or screw on the solenoid and turn it to the 'OPEN' position for continuous water flow, or 'CLOSE' to stop the flow. Remember to return it to the 'AUTO' or 'CLOSED' position for automatic operation.
6. Maintenance
- Solenoid Filter: The solenoid is equipped with an anti-sand filter. Periodically inspect and clean this filter to prevent blockages and ensure proper valve operation.
- Winterization: In regions prone to freezing temperatures, it is crucial to drain the irrigation system, including the solenoid valve, to prevent damage from freezing water. Consult your irrigation system's winterization guide.
- General Inspection: Annually inspect the valve for any signs of wear, leaks, or damage. Ensure electrical connections remain secure and waterproof.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve does not open | No power to solenoid; faulty wiring; clogged filter; low water pressure. | Check programmer schedule and power supply; inspect wiring connections; clean solenoid filter; verify water pressure. |
| Valve does not close | Debris in valve; faulty solenoid; manual override engaged. | Flush the system to clear debris; inspect/replace solenoid; ensure manual override is in 'CLOSED' or 'AUTO' position. |
| Low water flow | Partially clogged filter; insufficient main water pressure. | Clean solenoid filter; check main water supply pressure. |
| Water leaks from valve | Loose connections; damaged O-rings/seals; cracked valve body. | Tighten connections; inspect and replace O-rings/seals; replace valve if body is cracked. |
