3. Setup
- Placement: Position the pump on a stable, level surface in a dry, well-ventilated area, protected from frost and direct sunlight. Ensure adequate space for ventilation and maintenance.
- Suction Line Connection: Connect the suction line from your water source (e.g., well, cistern) to the pump's suction inlet. Ensure all connections are airtight to prevent air ingress, which can affect pump performance. Use appropriate seals and fittings.
- Pressure Line Connection: Connect the pressure line from the pump's outlet to your household water system or irrigation system. Again, ensure all connections are secure and leak-free.
- Priming the Pump: Before initial operation, the pump must be primed. Open the priming plug (usually located on top of the pump housing) and fill the pump housing completely with water until it overflows. Close the priming plug securely.
- Electrical Connection: Connect the pump to a grounded electrical outlet with the correct voltage and frequency as specified on the pump's rating plate. Ensure the electrical circuit is protected by a residual current device (RCD).
4. Operating Instructions
- Initial Start-up: After priming and connecting, switch on the power supply to the pump. The pump should start and build pressure. If it does not start or fails to build pressure, switch it off immediately and refer to the troubleshooting section.
- Automatic Operation: Hydrophore pumps are designed for automatic operation. They will switch on when water pressure drops below a set threshold (e.g., when a tap is opened) and switch off when the pressure reaches the upper threshold.
- Monitoring: Periodically check the pressure gauge (if equipped) to ensure the pump is operating within its normal pressure range. Listen for unusual noises or vibrations.
- Shutting Down: To temporarily stop the pump, simply close all water outlets. For extended periods of non-use, disconnect the pump from the power supply.
5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Winterization: In areas prone to freezing temperatures, drain the pump completely to prevent damage from freezing water. Disconnect all hoses and open drain plugs. Store the pump in a frost-free environment.
- Cleaning: Keep the pump and its ventilation openings clean and free from debris. Do not use harsh chemicals for cleaning.
- Check Connections: Periodically inspect all hose and pipe connections for leaks. Tighten any loose fittings.
- Pressure Tank (if applicable): If your model includes a separate pressure tank, check its air pressure annually and recharge if necessary according to manufacturer specifications.
6. Troubleshooting
Before contacting service, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power supply; Motor overload; Faulty switch. | Check power connection and circuit breaker; Allow motor to cool; Consult a qualified electrician. |
| Pump runs but no water or low pressure. | Pump not primed; Air in suction line; Suction line blocked; Water level too low. | Re-prime the pump; Check suction line for leaks; Clear any blockages; Ensure adequate water supply. |
| Pump switches on and off frequently. | Pressure tank air pressure too low; Leak in the system; Pressure switch faulty. | Check and adjust pressure tank air pressure; Inspect system for leaks; Consult a technician for pressure switch. |
If the problem persists after attempting these solutions, please contact qualified service personnel.
