4. Инсталација
Proper installation is crucial for the pump's performance and longevity. Follow these guidelines:
- Позиција на монтирање: Install the pump with the motor axis horizontal.
- Врски на цевки: The Evosta 2 40-70/130 is equipped with 1" (G 1") threaded connections. The 1/2" designation refers to the thread intended for connection to 1" to 1/2" reduced female fittings. Verify compatibility with your existing pipes or fittings.
- Напојување: Connect the pump to a single-phase 1 x 230 V ~ 50/60 Hz power supply. Ensure the electrical installation complies with local regulations.
- Системско испирање: Before starting the pump, ensure the system is thoroughly flushed to remove any debris that could damage the pump.
- Прочистување на воздухот: The pump includes an integrated air bleed plug. After filling the system, open the plug to release any trapped air.
Refer to the dimensional drawings for precise measurements and connection details to ensure proper fitment within your system.
5. Операција
The Evosta 2 pump features a control panel on the electronic control device cover, allowing for easy adjustment of its functions. The pump offers nine setting options, selectable via the MODE button.
- Избор на поставки: Press the MODE button to cycle through the available settings. The selected setting is indicated by six illuminated segments on the display.
- Работни режими: The pump supports various operating modes, typically including proportional pressure, constant pressure, and constant curve modes, to adapt to different system requirements.
Consult the specific icons or indicators on your pump's control panel to identify the active operating mode and adjust as needed for your heating or cooling system.
6. Одржување
Regular maintenance ensures the long-term reliability and efficiency of your Evosta 2 pump.
- Прочистување на воздухот: Periodically check and, if necessary, open the integrated brass air bleed plug to release any air trapped in the pump. This prevents cavitation and ensures smooth operation.
- Crankshaft Unlocking: In case of a blockage, the pump provides direct access to the crankshaft for manual unlocking. Refer to the technical diagrams for the exact location.
- Чистење: Keep the exterior of the pump clean and free from dust and debris. Do not use abrasive cleaners.
- System Fluid: Ensure the pumped liquid remains clean and free of solid substances and mineral oils. Glycol content should not exceed 30%.
- No Overload Protection Needed: Due to internal motor protection, no external overload protection is required.
7 Смена на проблеми
If you encounter issues with your Evosta 2 pump, consider the following common problems and solutions:
- Пумпата не стартува:
- Проверете го напојувањето и прекинувачот.
- Ensure the pump is properly connected to the electrical mains.
- Verify that the motor is not seized. Use the direct access to the crankshaft to attempt manual unlocking if necessary.
- No Flow or Reduced Flow:
- Check for air in the system. Bleed air using the integrated plug.
- Inspect for blockages in the pipes or pump impeller.
- Ensure valves in the system are open.
- Verify the selected operating mode and setting are appropriate for the system's requirements.
- Невообичаен шум:
- Noise can indicate air in the system. Purge air.
