3. Postavljanje i instalacija
Proper installation is crucial for the pump's performance and longevity. Refer to the diagram below for a typical installation setup.

Slika 1: Typical installation diagram, performance curves, and dimensional data for Pedrollo UPm2/4-GE submersible pumps. This image illustrates how the pump should be submerged in a water source, connected to a discharge pipe, and includes technical specifications and performance characteristics.
- Potapanje: The pump must be fully submerged in clean water. Ensure the water level is always above the pump's intake.
- Montaža: Secure the pump using a suitable rope or chain attached to the designated lifting point. Do not let the pump rest directly on the bottom if it's muddy or sandy.
- Ispusna cijev: Connect a discharge pipe of appropriate diameter to the pump's outlet. Ensure all connections are watertight.
- Električni priključak: Connect the pump to a 240V power supply with proper grounding and a residual current device (RCD) for safety. Consult a qualified electrician if unsure.
- Plutajući prekidač: If equipped with a float switch (as shown in Figure 1), ensure it can move freely to control the pump's on/off cycles based on water level.
4. Uputstvo za upotrebu
Once installed correctly, operating the Pedrollo UPm2/4-GE pump is straightforward:
- Prvo pokretanje: Ensure the pump is fully submerged and all connections are secure. Turn on the power supply. The pump will start automatically if the float switch is in the 'on' position (water level high enough).
- Kontinuirani rad: The pump is designed for continuous operation within its specified limits. Monitor the water level to prevent dry running, especially if not using a float switch.
- Ugasiti: To stop the pump, turn off the power supply. If using a float switch, the pump will stop automatically when the water level drops below the minimum operating level.
- Kvalitet vode: The pump is intended for clean water. Pumping water with excessive sediment or debris can damage the impellers and motor.
5. Održavanje
Regular maintenance ensures optimal performance and extends the pump's lifespan. Always disconnect power before maintenance.
- čišćenje: Periodically inspect the pump's intake screen for blockages from debris. Clean as necessary.
- Inspekcija impelera: While the pump's design resists blocking, occasional inspection of the impellers for wear or damage is recommended, especially if performance degrades. This typically requires professional service.
- Inspekcija kablova: Check the power cable for any signs of damage, cuts, or fraying. Replace immediately if damaged.
- Zimljenje: In freezing climates, remove the pump from the water source and store it in a frost-free environment if it will not be used during winter. Drain all water from the pump and pipes.
