1. Pengenalan
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. Pemasangan
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. Lokasi Pemasangan
- 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.
- Pastikan pengudaraan yang mencukupi di sekeliling 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. Sambungan Elektrik
- AMARAN: 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. Operasi
6.1. Permulaan Permulaan
- 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. Operasi Biasa
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.
- Tetapan Semula Automatik: 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.
- Reset Manual: 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. Penyelenggaraan
The Pedrollo Easy Press-1 is designed for minimal maintenance. However, regular checks can ensure its longevity and optimal performance.
- Pemeriksaan Visual: Periodically inspect the unit for any signs of damage, leaks, or corrosion.
- Kebersihan: Keep the exterior of the unit clean and free from dust and debris. Use a soft, damp kain untuk pembersihan; jangan gunakan pembersih atau pelarut yang kasar.
- Sambungan: Check hydraulic and electrical connections periodically to ensure they remain tight and secure.
- Musim sejuk: In areas prone to freezing temperatures, ensure the unit and associated piping are drained or protected from frost to prevent damage.
