4. Setup and Installation
The IBO BETA2 25-40/180 pump is designed for easy installation. However, professional installation by a qualified technician is recommended to ensure proper functioning and compliance with all local codes and regulations.
4.1 Pre-Installation Checks
- Verify that the installation site meets the ambient temperature requirements (0 °C to 40 °C).
- Ensure the power supply is 230V and adequately protected.
- Confirm that the pipe connections are clean and free of debris.
4.2 Mounting the Pump
- Choose a suitable location in the heating or hot water system where the pump can be easily accessed for maintenance.
- Ensure the pump is mounted horizontally with the motor shaft in a horizontal position to ensure proper lubrication and cooling.
- Use the provided screw fittings to connect the pump to the system piping. Ensure a tight, leak-free connection. The connection diameter is 1 ½ inches, with a distance of 180 mm between connections.
4.3 Electrical Connection
- Ensure the main power supply is switched off before making any electrical connections.
- Connect the provided power cable to the pump's electrical terminal block according to the wiring diagram (refer to the diagram on the pump or in the packaging if available).
- Connect the other end of the power cable to a grounded 230V power outlet.
- Verify all connections are secure and properly insulated.
4.4 System Filling and Venting
- After installation, fill the heating or hot water system with water.
- Vent the system thoroughly to remove any trapped air. Air in the system can cause noise, reduce pump efficiency, and lead to damage.
5. Operating Instructions
The IBO BETA2 25-40/180 pump features an electronic control system for intuitive operation.
5.1 Initial Start-up
- After ensuring the system is filled and vented, switch on the main power supply to the pump.
- The electronic display will illuminate, showing the current operating status and energy consumption.
5.2 Adjusting Speed Settings
The pump offers 11 speed settings to adapt to various system requirements. Use the control buttons on the display panel (e.g., PP1, PP2, CP1, CP2, ECO) to cycle through the available modes and speeds. The display will indicate the selected setting and corresponding energy consumption.
- ECO Mode: For energy-efficient operation.
- PP Modes: Proportional pressure modes, where pump head adjusts proportionally to flow rate.
- CP Modes: Constant pressure modes, maintaining a constant differential pressure.
Consult your heating system's requirements or a qualified technician to determine the optimal setting for your application.
5.3 Monitoring Operation
The electronic display provides real-time feedback on:
- Current energy consumption (in Watts)
- Selected operating mode/speed
- Any error codes (if applicable)
The pump operates quietly, with a sound pressure level of 43 dB.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your IBO BETA2 25-40/180 pump.
