1. Introduction
The Pedrollo Easy Press-1 is an electronic pressure controller designed for single-phase electric pumps. This device automates the starting and stopping of the pump based on water demand (opening and closing of taps). It incorporates microprocessor logic to protect the pump from dry running, offering both automatic and manual reset functions. Furthermore, it safeguards the electric pump against frequent starts caused by minor leaks in the system. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Easy Press-1 controller.

5. Installation
Proper installation is crucial for the safe and efficient operation of the Easy Press-1. It is highly recommended that installation be carried out by a qualified technician.
5.1. Mounting Location
- Install the device in a vertical position, ensuring the flow direction arrows on the unit match the water flow.
- Choose a location protected from direct sunlight, frost, and excessive humidity.
- Ensure adequate ventilation around the unit.
5.2. Hydraulic Connections
- Connect the inlet of the Easy Press-1 to the pump outlet.
- Connect the outlet of the Easy Press-1 to the water distribution system.
- Use appropriate sealing materials (e.g., PTFE tape) on the 1-inch male threaded connections to prevent leaks.
- Ensure all connections are tight but do not overtighten.
5.3. Electrical Connections
- WARNING: Ensure the main power supply is disconnected before making any electrical connections.
- Connect the main power supply (230V, 50/60Hz) to the designated input terminals of the Easy Press-1.
- Connect the single-phase electric pump to the designated output terminals of the Easy Press-1.
- Ensure proper grounding for both the Easy Press-1 and the electric pump.
- Verify all connections are secure and insulated according to electrical standards.
6. Operation
6.1. Initial Start-up
- After completing all hydraulic and electrical connections, ensure the pump is primed (filled with water) if required by the pump manufacturer.
- Open a tap in the system to allow water to flow.
- Restore power to the Easy Press-1. The green POWER indicator should illuminate.
- The pump will start automatically and run until the system is pressurized and the tap is closed.
- Close the tap. The pump should stop after a few seconds.
6.2. Normal Operation
The Easy Press-1 operates automatically:
- When a tap is opened, the pressure in the system drops, and the Easy Press-1 starts the pump.
- When the tap is closed, the pressure rises, and the Easy Press-1 stops the pump after a short delay.
6.3. Dry-Run Protection and Automatic Reset
If the pump runs without water (dry running), the Easy Press-1 will detect this condition and stop the pump to prevent damage. The red STATUS indicator will illuminate.
- Automatic Reset: The device will attempt to restart the pump periodically (e.g., every 15-30 minutes) to check if water has returned. If water is detected, normal operation resumes.
- Manual Reset: To manually reset the device after a dry-run event, press the START/STOP button. Ensure the water supply to the pump has been restored before attempting a manual reset.
7. Maintenance
The Pedrollo Easy Press-1 is designed for minimal maintenance. However, regular checks can ensure its longevity and optimal performance.
- Visual Inspection: Periodically inspect the unit for any signs of damage, leaks, or corrosion.
- Cleanliness: Keep the exterior of the unit clean and free from dust and debris. Use a soft, damp cloth for cleaning; do not use abrasive cleaners or solvents.
- Connections: Check hydraulic and electrical connections periodically to ensure they remain tight and secure.
- Winterization: In areas prone to freezing temperatures, ensure the unit and associated piping are drained or protected from frost to prevent damage.
8. Troubleshooting
This section provides solutions to common issues you might encounter with your Easy Press-1 controller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start when tap is opened. | No power supply. Dry-run protection activated. Faulty wiring. | Check power connection and circuit breaker. Check water supply to pump; press START/STOP button to reset. Verify all electrical connections are secure. Consult a qualified technician. |
| Pump runs continuously. | Leak in the system. Tap not fully closed. Pressure sensor malfunction. | Inspect plumbing for leaks and repair. Ensure all taps are completely closed. Contact technical support. |
| Pump starts and stops frequently (short cycling). | Small leak in the system. Check valve issue. Insufficient water supply. | Inspect plumbing for minor leaks and repair. Check the pump's check valve for proper function. Ensure adequate water supply to the pump. |
| Red STATUS indicator is on. | Dry-run protection activated. | Check water supply to the pump. Once water is restored, press the START/STOP button to manually reset, or wait for automatic reset. |
