Connexions de canonades: Connect the pump to the piping using appropriate flanges and gaskets. Ensure connections are watertight and do not overtighten.
Connexió elèctrica:
- Disconnect main power supply before wiring.
- Obriu la tapa de la caixa de terminals.
- Connect the power supply wires (Line, Neutral, Ground) to the corresponding terminals inside the pump's terminal box. Refer to the wiring diagram inside the terminal box cover.
- Assegureu-vos que totes les connexions estiguin segures i aïllades correctament.
- Close the terminal box cover securely to protect against moisture.
Filling and Venting: After installation, slowly fill the system with water. Vent any air from the pump and system by opening air vents until a steady stream of water emerges.
Comprovació de fuites: Inspeccioneu totes les connexions per detectar fuites un cop el sistema estigui pressuritzat.
