Setup and Installation
Proper installation is critical for the pump's performance and longevity. Consult a qualified professional if you are unsure about any step.
Pre-Installation Checklist:
- Verify power supply matches pump requirements (1 x 230V).
- Ensure adequate space for pump placement and maintenance access.
- Inspect the pump for any shipping damage.
Installation Steps:
- Positioning: Place the pump on a solid, level surface in the sump or basin. Ensure it is not resting directly on sludge or debris.
- Discharge Piping: Connect the discharge piping to the pump's outlet. Use a check valve to prevent backflow and a gate valve for isolation during maintenance.
- Electrical Connection: Connect the pump to a dedicated electrical circuit with proper overcurrent protection. All wiring must be done by a licensed electrician and conform to local electrical codes.
- Testing: After installation, fill the sump with water and cycle the pump several times to ensure proper operation and check for leaks.

Operating Instructions
The EBARA 50DWXU6.75S2 is a manual pump, meaning its operation is controlled externally, typically by a control panel or float switch system (not included with the pump itself).
Initial Start-up:
- Ensure the pump is fully submerged in the liquid to be pumped.
- Verify all piping connections are secure and leak-free.
- Turn on the power supply to the pump's control circuit.
- Activate the pump manually via its control panel or by raising the float switch (if installed) to initiate pumping.
Normal Operation:
The pump will operate when activated and will continue to pump until manually shut off or until the liquid level drops below its intake, depending on the control system used. Avoid running the pump dry for extended periods, as this can cause damage.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump. Always disconnect power before performing any maintenance.
Routine Checks (Monthly):
- Sump/Basin Inspection: Check the sump for excessive debris or sludge buildup that could impede pump operation.
- Pump Housing: Inspect the pump for any visible damage or corrosion.
- Discharge Line: Ensure the discharge line is clear and free of obstructions.
- Operation Test: Manually cycle the pump to ensure it starts and stops correctly and pumps efficiently.
Annual Maintenance:
- Consider having a qualified technician inspect the motor, impeller, and seals for wear.
- Clean the pump thoroughly to remove any accumulated residue.
Troubleshooting
Before attempting any repairs, ensure the power supply to the pump is disconnected.
| Problem | Possible Cause | Solution |
