5. Setup and Installation
Proper installation is critical for the pump's performance and longevity. Follow these steps carefully:
- Placement: Position the pump on a stable, flat surface at the bottom of the well, tank, or sump. Ensure there is sufficient space around the pump for water intake and cooling.
- Submersion Depth: Ensure the pump is fully submerged in the liquid during operation. Refer to the installation diagrams for minimum and maximum submersion depths.
- Discharge Pipe: Connect a suitable discharge pipe to the pump's outlet. Use a non-return valve if the pump is used in an application where backflow could occur. Ensure all connections are watertight.
- Float Switch (if applicable): Adjust the float switch to the desired ON/OFF levels. The float switch automatically starts and stops the pump based on water levels. Ensure the float switch can move freely without obstruction.
- Electrical Connection: Connect the pump to a grounded electrical outlet with the correct voltage and frequency. Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and the pump's power requirements.

6. Operating Instructions
Once installed, operating the Pedrollo Top 5N pump is straightforward:
- Initial Start-up: Ensure the pump is fully submerged and all connections are secure. Plug the pump into the grounded electrical outlet.
- Automatic Operation: If equipped with a float switch, the pump will start automatically when the water level rises to the 'ON' position and stop when it drops to the 'OFF' position.
- Monitoring: Periodically check the pump's operation to ensure it is running smoothly and efficiently. Listen for unusual noises or vibrations.
- Dry Running: Avoid dry running the pump, as this can cause severe damage to the motor and seals. The float switch is designed to prevent dry running in automatic mode.
7. Performance Curves
The performance curves illustrate the relationship between the pump's flow rate (Q) and its total head (HMT H) at a specific motor speed (n) and frequency. These curves are essential for determining if the pump meets the requirements of your specific application.
Figure 6: Performance curves for Pedrollo TOP series pumps (50 Hz, 2900 rpm). This graph shows the head (HMT H in meters and feet) versus flow rate (Debit Q in m³/h and l/min) for various TOP models, including TOP 5N. Locate the curve labeled "TOP5 N" to understand its specific performance characteristics.
To interpret the curve for your TOP 5N model, find the line labeled "TOP5 N". For a given flow rate on the horizontal axis (Debit Q), trace vertically up to the "TOP5 N" curve, then horizontally to the left axis to find the corresponding head (HMT H). This indicates the maximum height the pump can lift water at that specific flow rate.
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump. Always disconnect the pump from the power supply before performing any maintenance.
- Cleaning: Periodically clean the pump's intake screen to remove any debris that may obstruct water flow.
- Inspection: Inspect the power cord and plug for any signs of damage. Check for leaks around connections.
- Winterization: If the pump is used in an area subject to freezing temperatures, remove it from the water and store it in a frost-free location. Drain all water from the pump to prevent damage.
- Professional Service: For internal repairs or complex issues, contact a qualified service technician or Pedrollo authorized service center.
9. Troubleshooting
Refer to the following table for common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply | Check power connection, circuit breaker, and fuse. |
| Pump does not start | Float switch stuck or incorrectly adjusted | Ensure float switch moves freely and is at the correct level. |
| Pump runs but no water is discharged | Intake screen blocked | Disconnect power and clean the intake screen. |
| Pump runs but no water is discharged | Air lock in the pump or discharge pipe | Ensure pump is fully submerged. Briefly lift and lower the pump to release trapped air. |
| Reduced flow rate | Partial blockage in intake or discharge pipe | Inspect and clear any blockages. |
| Pump stops unexpectedly | Overheating (thermal overload protection activated) | Allow pump to cool down. Check for blockages or dry running. Ensure proper ventilation if not fully submerged (though this is a submersible pump, overheating can still occur if flow is restricted). |
If the problem persists after attempting these solutions, contact Pedrollo customer support or a qualified technician.
