5. Operating Instructions
Once installed and the system is filled and vented:
- Power On: Restore power to the pump. The pump should start operating.
- Speed Setting: The pump typically features multiple speed settings. Adjust the speed using the control dial on the pump head to match the system's requirements. Higher settings provide greater flow and head.
- Monitoring: Observe the system for proper circulation and ensure there are no unusual noises or leaks. The pump has a maximum flow rate of 10 liters per minute.

6. Maintenance
The IBO OHI 25-40/180 pump is designed for minimal maintenance. However, regular checks can extend its lifespan:
- Annual Inspection: Annually inspect the pump for any signs of leaks, corrosion, or unusual noises.
- Cleaning: Keep the exterior of the pump clean and free from dust and debris to ensure proper cooling.
- System Water Quality: Ensure the heating system water quality is maintained according to manufacturer recommendations to prevent scale buildup and corrosion within the pump.
- Winterization: If the system is shut down for an extended period in freezing conditions, ensure the pump and pipes are drained to prevent damage.
7. Troubleshooting
Before contacting support, perform these basic troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply; Motor seized; Air in pump | Check power connection and circuit breaker; Attempt to free rotor (if accessible and safe); Vent the pump. |
| Insufficient flow | Air in system; Incorrect speed setting; Blockage in pipes/pump | Vent the system; Adjust speed setting; Check for blockages (requires professional intervention). |
| Loud operation/Vibration | Air in pump/system; Improper mounting; Worn bearings | Vent the pump/system; Check mounting for stability; Contact a professional for inspection. |
| Leakage | Loose connections; Damaged seals | Tighten pipe connections; Contact a professional for seal replacement. |
