3. Kuiswa uye Setup
Proper installation is crucial for the pump's performance and longevity. It is recommended that installation be performed by a qualified technician.
General Guidelines:
- Nzvimbo: Install the pump in a dry, well-ventilated area, protected from direct sunlight and frost. Ensure sufficient space for maintenance.
- Kukwidza: Securely mount the pump on a stable, level surface to minimize vibration.
- Piping: Use pipes of appropriate diameter to avoid excessive pressure loss. Ensure all connections are airtight to prevent air ingress, which can affect pump performance.
- Suction Line: The manometric suction lift should not exceed 7 meters. Install a foot valve with a strainer at the end of the suction line to prevent debris from entering the pump and to maintain prime.
- Kubatanidza Magetsi: The pump requires a three-phase, 400 V, 50 Hz power supply. Connect the pump to a suitable electrical circuit with appropriate overload protection, as per local electrical codes. Ensure the motor rotation direction is correct (check arrow on motor casing).
- Priming: Before initial startup, the pump body and suction line must be completely filled with water to ensure proper operation.
