- The pump is designed for 220V, 50Hz power supply. Ensure your electrical system matches these requirements.
4.2 Mounting the Pump
- Choose a suitable location for the pump, ensuring it is easily accessible for maintenance and protected from extreme weather conditions.
- Mount the pump securely to a stable surface to minimize vibration and noise.
- Connect the pump in-line with your existing water piping system. Ensure the flow direction matches the arrows on the pump body. The pump has an interface distance of 200mm.
- Use appropriate pipe fittings and sealants to ensure watertight connections.
4.3 Electrical Connection
- Connect the pump's power cord to a grounded electrical outlet that meets the specified voltage and frequency (220V, 50Hz).
- Ensure all electrical connections are secure and protected from moisture.
5. Operation
The Grundfos UPA90/120 pump is designed for fully automatic operation based on water flow detection.
5.1 Initial Start-up
- After installation, ensure all connections are secure and there are no leaks.
- Open a faucet in your system to allow water to flow through the pump.
- Connect the pump to the power supply. The pump will automatically detect water flow and begin operation, boosting the pressure.
- Allow the pump to run for a few minutes to purge any air from the system.
5.2 Automatic Functionality
- When you open a water tap or appliance, the pump's intelligent flow sensor will detect the water movement and automatically start, providing boosted water pressure.
- When you close the water tap or appliance, the pump will detect the cessation of water flow and automatically shut down.
6. Maintenance
Regular maintenance helps ensure the long-term reliability and efficiency of your pump.
- Periodic Inspection: Regularly check the pump and connections for any signs of leaks, corrosion, or damage.
- Cleaning: Keep the exterior of the pump clean and free from dust and debris. Do not use harsh chemicals for cleaning.
- Winterization (if applicable): If the pump is installed in an area subject to freezing temperatures, ensure it is properly drained or protected to prevent damage from freezing water.
- Professional Check: Consider an annual check-up by a qualified technician to ensure all components are functioning correctly.
