Setup and Installation

Follow these steps for proper installation of the water pump pressure controller.

1. Mounting: Securely mount the controller in a suitable location, ensuring it is protected from direct weather exposure if not rated for outdoor use.
2. Water Connection: Connect the water inlet (G1") of the controller to your water supply line. Ensure all connections are watertight.
3. Pump Connection: Connect the water pump's outlet to the controller's water outlet.
4. Electrical Connection (Power Supply): Connect the main 110V power supply to the 'Connect Power Supply' terminals on the controller. Ensure correct wiring for live, neutral, and ground (if applicable).
5. Electrical Connection (Water Pump): Connect the water pump's power cable to the 'Connect Water Pump' terminals on the controller.
6. Initial Fill: Before powering on, ensure the pump and suction line are primed with water to prevent dry running.

Operating Instructions

The controller is designed for fully automatic operation.

1. Power On: Once installed and connected, apply power to the controller. The 'Power on Indicator' LED will illuminate.
2. Automatic Operation: The controller will automatically detect water pressure changes. When water is demanded (e.g., a tap is opened), the pressure drops, and the controller will activate the pump. The 'Pump on Indicator' LED will illuminate.
3. Pump Off: When water demand ceases and pressure is restored, the controller will automatically turn off the pump. The 'Pump on Indicator' LED will turn off.
4. Dry Running Protection: If the water supply to the pump runs out, the controller will automatically stop the pump to prevent damage. The 'Failure Indicator' LED will illuminate.
5. Restarting After Failure: If the 'Failure Indicator' is lit due to dry running, ensure the water supply is restored. Then, press the 'Restart Button' to reset the controller and resume pump operation.

Maintenance

Regular maintenance ensures optimal performance and longevity of your controller.

• Regular Inspection: Periodically check all electrical and water connections for leaks, corrosion, or loose wiring.
• Cleaning: Keep the exterior of the controller clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Winterization: In cold climates, ensure the controller and associated plumbing are protected from freezing temperatures to prevent damage.
• Pressure Gauge Check: Monitor the pressure gauge for consistent readings during operation.
