1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your ESPA PRESSCONTROL PRESSDRIVE 05 automatic pump control unit. Please read this manual thoroughly before installation and use, and keep it for future reference. The PRESSDRIVE 05 is designed to automate the starting and stopping of domestic water pumps based on water demand, providing constant pressure and protecting the pump from dry running.
2. Safety Information
Always observe the following safety precautions to prevent personal injury and damage to the unit:
- Electrical Safety: Disconnect power to the pump and the PRESSDRIVE 05 before performing any installation, maintenance, or repair work. All electrical connections must be performed by a qualified electrician and comply with local electrical codes.
- Water Pressure: Ensure the system is depressurized before disconnecting any hydraulic connections.
- Installation: Install the unit in a protected area, away from direct sunlight, rain, or freezing temperatures.
- Intended Use: Use the PRESSDRIVE 05 only for its intended purpose as an automatic pump control for clean water systems. Do not use with flammable, corrosive, or abrasive liquids.
- Children and Unauthorized Personnel: Keep children and unauthorized personnel away from the pump system during operation.
3. Product Overview
The ESPA PRESSCONTROL PRESSDRIVE 05 is a compact and reliable electronic device designed to manage the operation of a water pump. It automatically starts the pump when pressure drops (e.g., when a tap is opened) and stops it when the flow ceases (e.g., when a tap is closed). It also incorporates dry-running protection, which stops the pump if there is no water supply, preventing damage.

5. Installation (Setup)
Proper installation is crucial for the optimal performance and longevity of your PRESSDRIVE 05. Follow these steps carefully:
- Mounting: Install the PRESSDRIVE 05 vertically on the pump's discharge outlet or on the main delivery pipe. Ensure the flow direction arrow on the unit matches the water flow.
- Hydraulic Connections: Connect the inlet of the PRESSDRIVE 05 to the pump's discharge and the outlet to the domestic water system. Use appropriate sealing materials (e.g., PTFE tape) to ensure watertight connections. The unit features G1" connections.
- Electrical Connections: Connect the pump's power cable to the designated terminals within the PRESSDRIVE 05, and connect the main power supply cable to the unit's input terminals. Ensure all connections are secure and correctly insulated. Refer to the wiring diagram inside the unit's cover.
- Priming the System: Before starting the pump, ensure the pump and the PRESSDRIVE 05 are completely filled with water. Open a tap in the system to allow air to escape.
- Power On: Once all connections are secure and the system is primed, restore power. The pump should start and run until the system is pressurized and all air is expelled.
6. Operation
The ESPA PRESSDRIVE 05 operates automatically once installed and powered. It requires no manual adjustment under normal conditions.
- Automatic Start: When a tap or valve in the system is opened, the pressure in the pipe drops. The PRESSDRIVE 05 detects this pressure drop and automatically starts the pump.
- Automatic Stop: When all taps and valves are closed, the water flow stops. The PRESSDRIVE 05 detects the cessation of flow and automatically stops the pump after a short delay, maintaining system pressure.
- Dry-Run Protection: If the pump runs out of water (e.g., the well or tank is empty), the PRESSDRIVE 05 will detect the lack of flow and stop the pump to prevent damage.
- Automatic Reset: After a dry-run shutdown, the unit will attempt to restart the pump periodically (e.g., every 15-30 minutes) to check if water supply has been restored. This feature eliminates the need for manual resets in many cases.
7. Maintenance
The ESPA PRESSDRIVE 05 is designed for minimal maintenance. However, regular checks can ensure its long-term reliability:
- Visual Inspection: Periodically check the unit and connections for any signs of leaks, corrosion, or physical damage.
- Cleanliness: Keep the exterior of the unit clean and free from dust or debris.
- Winterization: In areas prone to freezing temperatures, ensure the unit and associated piping are drained or protected from frost to prevent damage.
- Electrical Connections: Annually, with power disconnected, check electrical terminals for tightness and absence of corrosion.
8. Troubleshooting
If you encounter issues with your PRESSDRIVE 05, consult the following table before contacting technical support:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start when tap is opened. | No power supply; Dry-run protection activated; Clogged inlet/outlet. | Check power connection and circuit breaker; Check water supply to pump; Clean connections. |
| Pump does not stop after closing taps. | Leak in the system; Small continuous flow; Faulty pressure sensor. | Check for leaks in pipes or fixtures; Ensure all taps are fully closed; Contact service if sensor is suspected. |
| Pump starts and stops frequently (cycling). | Small leak in the system; Insufficient water supply; Air in the system. | Check for leaks; Ensure adequate water source; Re-prime the pump and system to remove air. |
| Low water pressure. | Pump not performing optimally; Partial blockage; Incorrect pump selection. | Check pump condition; Inspect for blockages; Consult pump specifications. |
If problems persist after attempting these solutions, please contact a qualified technician or the manufacturer's support.
