3. Bezpečnostní informace

• Always disconnect power before installing, servicing, or removing the solenoid valve.
• Před prací na ventilu se ujistěte, že je v systému uvolněn tlak.
• Používejte vhodné osobní ochranné prostředky (OOP), jako jsou ochranné brýle a rukavice.
• Instalaci a údržbu by měl provádět pouze kvalifikovaný personál.
• Verify that the valve's specifications (pressure, temperature, fluid compatibility) match the application requirements.
• Avoid exposing the valve to excessive mechanical stress or vibration.

4. Instalace

4.1 Kontroly před instalací

• Inspect the valve for any signs of damage during shipping.
• Confirm that the model number (032F1204) and specifications match your order and application.
• Ujistěte se, že máte k dispozici veškeré potřebné nástroje a příslušenství.

4.2 Montáž a připojení

1. Mount the valve in a position that allows for easy access for maintenance and inspection. The valve can be installed in any position, but it is recommended to install with the coil upwards to prevent accumulation of debris.
2. Ujistěte se, že šipka směru průtoku na tělese ventilu shoduje s průtokem kapaliny v systému.
3. Connect the 3/8 inch ODF pipes to the valve's inlet and outlet ports. Use appropriate flaring tools and techniques to ensure a leak-free connection.
4. Tighten connections to the manufacturer's recommended torque specifications to prevent leaks without over-stressing the valve body.

4.3 Elektrické připojení

• Zajistěte napájení objtage and frequency match the specifications of the solenoid coil.
• Connect the solenoid coil to the appropriate electrical circuit. Follow local electrical codes and safety standards.
• Secure all electrical connections to prevent accidental disconnection or short circuits.

5. Provoz

The Danfoss EVR 3 (032F1204) is a normally closed (NC) solenoid valve. This means that when the solenoid coil is de-energized (no power), the valve remains closed, preventing fluid flow. When the solenoid coil is energized (power applied), the valve opens, allowing fluid to pass through.

• Napájení cívky: Applying the specified voltage to the solenoid coil will open the valve.
• Odpojení cívky od napájení: Removing power from the solenoid coil will close the valve.

Monitor system pressure and flow rates after initial operation to ensure proper function and detect any anomalies.

6. Údržba

6.1 Rutinní kontrola

• Periodically check for external leaks around the connections and valve body.
• Inspect the solenoid coil for any signs of overheating, damage, or loose connections.
• Listen for unusual noises during operation, which may indicate internal issues.

6.2 Čištění

• Keep the exterior of the valve clean and free from dust, dirt, and corrosive substances.
• If internal cleaning is required, consult a qualified technician or Danfoss service representative. Disassembly by untrained personnel can void warranty and cause damage.

6.3 Coil Replacement

If the solenoid coil fails, it can typically be replaced without removing the entire valve from the system. Ensure the power is disconnected before attempting coil replacement. Refer to the specific coil's instructions for detailed replacement procedures.
