2. Safety Information
WARNING: Failure to follow these safety instructions could result in electric shock, fire, serious injury, or death.
- Always disconnect power before performing any installation, maintenance, or repair work on the pump.
- Ensure the electrical supply matches the pump's voltage and frequency requirements.
- All electrical connections must be performed by a qualified electrician and comply with local codes and regulations.
- The pump must be properly grounded to prevent electric shock.
- Do not operate the pump dry (without water), as this can cause severe damage.
- Install the pump in an enclosed environment or at least sheltered from inclement weather to protect it from environmental elements.
- Keep hands and loose clothing away from moving parts.
- Do not use the pump for flammable, corrosive, or explosive liquids.

4. Setup and Installation
Proper installation is crucial for the pump's performance and longevity. Ensure the installation site is stable, level, and provides adequate ventilation.
4.1. Location
The pump should be installed in an enclosed environment or at least sheltered from inclement weather to protect it from rain, direct sunlight, and extreme temperatures.
4.2. Plumbing Connections
- Use appropriate pipe sizes for the inlet and outlet ports (refer to dimensions table for DN1 and DN2).
- Ensure all connections are airtight to prevent air leaks, especially on the suction side.
- Install a foot valve with a strainer on the end of the suction pipe if drawing water from a well or tank.
- Install shut-off valves on both suction and discharge lines for ease of maintenance.
4.3. Electrical Connections
- Verify the power supply voltage and frequency match the pump's specifications (V.220-440/60HZ).
- Connect the pump to a dedicated circuit with appropriate overcurrent protection.
- Ensure proper grounding according to local electrical codes.

5. Operating Instructions
5.1. Priming the Pump
Before initial startup or after the pump has been drained, it must be primed. This involves filling the pump casing and suction line with water to remove all air.
- Close the discharge valve.
- Remove the priming plug (usually located on top of the pump casing).
- Slowly fill the pump casing with clean water until it overflows.
- Replace the priming plug securely.
- Open the discharge valve partially before starting the pump.
5.2. Starting and Stopping
- Starting: Ensure the pump is primed and all valves are correctly positioned. Turn on the power supply. The pump should start immediately.
- Stopping: Turn off the power supply. If the pump is part of a pressure system, it will stop automatically when the desired pressure is reached.
5.3. Performance Monitoring
Regularly monitor the pump's performance, including flow rate and pressure, to ensure it operates within its optimal range. Refer to the characteristic curves for expected performance.

6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Pedrollo pump.
6.1. Routine Checks
- Daily: Check for unusual noises, vibrations, or leaks.
- Weekly: Inspect the suction strainer (if installed) for blockages and clean if necessary.
- Monthly: Verify electrical connections are secure and free from corrosion.
6.2. Winterization (if applicable)
If the pump is installed in an area subject to freezing temperatures and will not be used, it must be drained to prevent damage from freezing water.
- Disconnect power to the pump.
- Open the drain plugs on the pump casing and piping to allow all water to escape.
- Store the pump in a dry, frost-free environment if possible.
7. Troubleshooting
This section provides solutions to common operational issues. For problems not listed here, contact qualified service personnel.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; Motor overload; Seized impeller | Check power supply/breaker; Reset overload; Contact service |
| Pump runs but no water | Pump not primed; Air leak in suction line; Suction lift too high; Clogged impeller/pipe | Prime pump; Check/seal connections; Reduce lift; Clear blockages |
| Low flow or pressure | Partial blockage; Air in system; Worn impeller; Incorrect pipe size | Clear blockages; Bleed air; Contact service; Verify pipe sizing |
| Excessive noise/vibration | Cavitation (air in water); Misalignment; Worn bearings | Check priming/suction; Check mounting; Contact service |
