4. Setup and Installation

4.1 Pre-Installation Checks

• Verify that the pump model matches your system requirements.
• Inspect the pump for any visible damage from shipping.
• Ensure all necessary tools and fittings are available.
• Confirm that the power supply (230 V- 50 Hz) is accessible and correctly rated.

4.2 Mounting the Pump

The pump should be installed in a horizontal position with the motor shaft horizontal to ensure proper lubrication and cooling. Ensure there is sufficient space around the pump for ventilation and future maintenance.

• Install the pump in the return line of the heating system, if possible, to operate at lower temperatures and extend its lifespan.
• Use appropriate shut-off valves on both sides of the pump to allow for isolation during maintenance without draining the entire system.
• Ensure the pipework is adequately supported to prevent strain on the pump connections.
• Use the provided seals to ensure watertight connections.

4.3 Electrical Connection

• All electrical work must be carried out by a qualified electrician.
• Connect the pump to a dedicated electrical circuit protected by a fuse or circuit breaker.
• Ensure proper grounding (earthing) of the pump.
• Follow the wiring diagram provided on the pump's terminal box or in the full manufacturer's documentation.

4.4 System Filling and Priming

• After installation, slowly fill the heating system with water, ensuring all air is vented from the system.
• Open the bleed screw on the pump (if present) to release any trapped air within the pump housing.
• Once the system is full and air-free, close the bleed screw.

5. Operating Instructions

5.1 Initial Start-up

• Ensure the system is completely filled with water and all air has been removed.
• Turn on the power supply to the pump.
• The pump should start operating. Listen for any unusual noises, which may indicate trapped air or an obstruction.

5.2 Speed Selection

The IBO 25-60/180 OHI pump is equipped with a 3-speed selector switch, typically located on the motor housing. This allows you to adjust the pump's performance to match the specific requirements of your heating system.

• Speed I (Low): For systems requiring minimal circulation or during periods of low heat demand.
• Speed II (Medium): A balanced setting for general operation.
• Speed III (High): For systems requiring maximum circulation, such as during initial heat-up or in larger systems.

Select the speed that provides adequate heat distribution without causing excessive noise or energy consumption. You may need to experiment to find the optimal setting for your system.

6. Maintenance

The IBO 25-60/180 OHI circulating pump is designed for minimal maintenance. However, regular checks can help ensure its long-term reliability.

• Annual Inspection: Annually, check the pump for any signs of leaks, corrosion, or unusual noises.
• System Water Quality: Ensure the heating system water is clean and free of debris. Poor water quality can lead to blockages and premature wear.
• Bleeding: Periodically check and bleed the system and pump to remove any trapped air, which can cause noise and reduce efficiency.
• Cleaning: Keep the exterior of the pump clean and free from dust and dirt to ensure proper heat dissipation.
• Winterization: If the heating system is shut down for an extended period in freezing conditions, ensure the system (including the pump) is drained or protected with antifreeze to prevent damage from freezing.

7. Troubleshooting

Before attempting any troubleshooting, always disconnect the pump from the power supply.
