1. Introducció
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Aqua Control C12033 Solenoid Valve. This electric valve is designed for use in automatic irrigation systems, ensuring reliable water flow control. Please read this manual thoroughly before installation and operation to ensure proper function and longevity of the product.
2. Informació de seguretat
- Always disconnect power before installing or performing maintenance on the valve.
- Ensure the operating pressure and temperature are within the specified limits (0.4 to 12 bar, +4°C to 70°C). Exceeding these limits can damage the valve and irrigation system.
- Install the valve in a location protected from direct sunlight and freezing temperatures to prevent damage.
- Use appropriate thread sealant on all connections to prevent leaks.

Components clau:
- Cos de la vàlvula: The main housing, made of reinforced nylon, with inlet and outlet ports.
- Solenoid Coil: The electromagnetic component that, when energized, opens or closes the valve. It has two electrical wires for connection.
- Anulació manual: A knob or lever (visible on top of the valve) that allows for manual operation of the valve without electrical power.
- Ports d'entrada/sortida: 3/4-inch male threaded connections for integration into the irrigation piping system.
4. Configuració i instal·lació
Segueix aquests passos per a la correcta instal·lació de la vàlvula solenoide:
- Preparar la ubicació: Choose a location that is easily accessible for maintenance and protected from extreme weather conditions. Ensure the piping is clean and free of debris.
- Orient the Valve: Identify the inlet and outlet ports. The valve typically has an arrow indicating the direction of water flow. Install the valve so that water flows in the correct direction.
- Aplicar segellador de rosques: Apply appropriate thread sealant (e.g., PTFE tape) to the male threads of the valve before connecting to the irrigation pipes.
- Connect to Piping: Carefully thread the valve into the irrigation system's female fittings. Hand-tighten first, then use a wrench for a final snug fit. Do not overtighten, as this can damage the plastic threads.
- Connexió elèctrica: Connect the two wires from the solenoid coil to your irrigation controller's common and zone wire terminals. Ensure all electrical connections are secure and waterproof, especially if installed outdoors.
- Prova de fuites: Slowly turn on the water supply to the system and check all connections for leaks. Tighten any leaking connections as needed.

5. Instruccions de funcionament
The Aqua Control C12033 Solenoid Valve operates primarily through an irrigation controller. It also features a manual override option.
Funcionament automàtic:
Once connected to an irrigation controller, the valve will open and close according to the programmed schedule. When the controller sends an electrical signal to the solenoid, the valve opens, allowing water to flow. When the signal is removed, the valve closes.
Funcionament manual:
To manually open the valve without electrical power, locate the manual override knob on top of the valve. Turn the knob counter-clockwise to open the valve and clockwise to close it. Ensure the manual override is fully closed for automatic operation.
6. Manteniment
Regular maintenance ensures optimal performance and extends the lifespan of your solenoid valve.
- Inspecció periòdica: Regularly inspect the valve for any signs of leaks, cracks, or damage. Check electrical connections for corrosion or loose wiring.
- Neteja: If the valve is exposed to dirty water, sediment can accumulate. Disconnect power and water supply, then carefully remove the solenoid and inspect the diaphragm area for debris. Clean with clear water if necessary.
- Hivernització: In regions with freezing temperatures, it is crucial to drain the valve and associated piping before winter to prevent damage from freezing water. Consult your irrigation system's winterization guide for detailed steps.
