3. Compoñentes do produto
Familiarize yourself with the main components of your Truper BOS-1LM pump:

Imaxe 3.1: Labeled diagram of the Truper BOS-1LM pump and its control unit. Key components include: Suspension Eyelets (Ojos de suspensión), 2.5 mm Suction Holes (Orificios de succión de 2.5 mm), Stainless Steel Casing (Carcasa de acero inoxidable), 38 mm Discharge Connection (Conexión de descarga de 38 mm), Power Control Box (Caja de control de encendido), On/Off Switch (Interruptor encendido/apagado), and Overload Protection Switch (Interruptor de protección de sobrecarga).
4. Configuración
- Desembalaxe: Retire con coidado a bomba e todos os accesorios da embalaxe. Inspeccione se hai algún dano.
- Suspensión: Attach a strong rope or cable to the suspension eyelets at the top of the pump. This will be used to lower and retrieve the pump. Do not use the power cable for suspension.
- Conexión de descarga: Connect a 38 mm (1.5 inch) discharge hose or pipe to the pump's discharge connection. Ensure a secure and leak-free connection.
- Colocación da unidade de control: Mount the electrical control unit in a dry, accessible location, away from direct water exposure.
- Conexión eléctrica: Connect the pump's power cable to the control unit. Then, connect the control unit to a suitable grounded power outlet. Ensure the power supply matches the pump's voltage requisitos de frecuencia.
- Baixando a bomba: Slowly lower the pump into the water source using the suspension rope. Ensure the pump is fully submerged and rests vertically, not touching the bottom or sides of the well/tank.

Imaxe 4.1: The Truper BOS-1LM pump measures 71 cm in height and 9 cm in diameter, indicating its compact 'bullet' design suitable for narrow spaces.
5. Instrucións de funcionamento
Once the pump is properly installed and submerged, follow these steps for operation:
- Encendido: Ensure the overload protection switch on the control unit is in the 'ON' position. Press the 'ON' button on the control unit to start the pump.
- Monitor de fluxo: Observe the water flow from the discharge. The pump should begin pumping water immediately.
- Apagado: To stop the pump, press the 'OFF' button on the control unit.
- Curva de rendemento: Refer to the performance curve to understand the pump's flow rate (L/min) at different discharge heights (m). This helps in optimizing usage for your specific needs.

Imaxe 5.1: This image illustrates the pump's operation, showing it submerged in a well, pumping water with increased pressure. It also includes a performance curve graph, indicating the recommended use area and the relationship between pumping height (Altura in meters) and flow rate (Flujo in L/min) for the BOS-1LM model.
6. Mantemento
Un mantemento regular garante a lonxevidade e o rendemento óptimo da súa bomba.
- Limpeza de filtros: The pump has a filtering grid for particles up to 1.5 mm. Periodically inspect and clean the suction holes and filter to prevent blockages and maintain efficient flow.
- Inspección: Regularly inspect the pump body, power cable, and discharge hose for any signs of wear, damage, or corrosion. Replace damaged components immediately.
- Almacenamento: If the pump will not be used for an extended period, clean it thoroughly, drain all water, and store it in a dry, frost-free location.
- Protector térmico: The thermal protector automatically shuts off the motor if it overheats. If this occurs, disconnect power, allow the pump to cool, and check for blockages or low water levels before restarting.
