4. Kurulum ve Kurulum
Pompanın performansı ve uzun ömrü için doğru montaj çok önemlidir.
- Sistem Hazırlığı: Ensure the heating or cooling system is drained and clean before installation.
- Montaj Pozisyonu: The pump can be installed in any position, provided the motor shaft remains horizontal. This is critical for proper lubrication and cooling of the wet rotor.
- Boru Bağlantıları: The pump uses 3/4-inch to 1-1/2-inch standard flanges. Use appropriate gaskets (typically supplied with the pump) and ensure a watertight seal. Avoid overtightening the flange bolts.
- Elektrik Tesisatı:
- Disconnect power at the main breaker before beginning any wiring.
- Open the electrical connection box.
- The pump features quick and easy wire connectors. To insert wires, displace the white tabs 90 degrees to open the holes. Insert the stripped wires and then return the tabs to their original position to secure the connection.
- Connect the pump to a dedicated 115-Volt, 60Hz circuit. Ensure proper grounding.
- Close the electrical connection box securely.
- Sistem Doldurma: After installation, slowly fill the system with fluid, ensuring all air is purged from the pump and piping. Air in the system can cause noise and damage to the pump.
5. Kullanım Talimatları
The Wilo Star S 21F pump offers three selectable speeds to match system requirements.
- Güç Açık: Once the pump is installed and the system is filled, restore power to the circuit.
- Hız Seçimi: Locate the red rotary switch on the electrical connection box. This switch allows you to select one of three operating speeds:
- Hız 1 (Eko): Lowest power consumption (55W), suitable for minimal flow requirements.
- Hız 2: Medium power consumption (77W), for moderate flow.
- Speed 3 (Max): Highest power consumption (98W), for maximum flow and head.
- İzleme: Observe the system for proper circulation and listen for any unusual noises.
