Setup and Installation
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage during transit.
- Cable Connection: Ensure the connection cable is securely attached to the pump. The pump comes with a pre-attached cable.
- Pressure Connection: Connect your desired hose or pipe to the pump's brass threaded socket. The socket has a diameter of 87 mm and is compatible with 1 ¼" pipes. Ensure a tight, leak-free connection.
- Placement: Lower the pump into the well or water source. Ensure the well diameter is at least 4 inches. The pump must be fully submerged in water. The maximum immersion depth is 70 meters.
- Power Connection: Once the pump is securely placed and submerged, connect the power plug to a suitable electrical outlet (220V-240V).
