3. Ntọala na nwụnye

Proper installation is crucial for the pump's performance and longevity. Refer to the diagram below for a standard installation setup.

1. Ịkwanye: Securely mount the pump on a stable, level surface to minimize vibration.
2. Ahịrị mmiri: Connect a rigid suction pipe to the pump's inlet. Ensure the suction line is airtight to prevent air leaks, which can affect self-priming.
3. Valvụ Na-anaghị Alọghachi: Install a non-return valve (foot valve) at the end of the suction line, submerged in the water source, to prevent water from flowing back when the pump is off.
4. Delivery Line: Connect the delivery pipe to the pump's outlet.
5. Njikọ eletrik: Connect the pump to a dedicated 220V, 60Hz, single-phase power supply circuit protected by an appropriate circuit breaker. Consult an electrician for proper wiring.
6. Ndozi: Before initial startup, fill the pump casing completely with water through the priming port (if available) until water overflows. This assists the self-priming process.

4. Ọrụ

Once installed and primed, the Pedrollo SKRm2 pump is ready for operation.

1. Mmalite mbụ: After priming, switch on the power supply to the pump. The pump will begin to draw water.
2. Ịmepụta onwe: The SKRm2 is designed to self-prime. If the pump does not draw water within a few minutes, switch it off, re-check the priming, and ensure there are no air leaks in the suction line.
3. Ọrụ na-aga n'ihu: Monitor the pump during operation for any unusual noises or vibrations. Ensure the pump is not running dry, as this can cause damage.
4. Mechie: To stop the pump, simply switch off the power supply.
