Setup, Compatibility & Care
Setup
- Preparation: Turn off the power to the existing pump and close the isolation valves.
- Removal: Disconnect the old pump, noting the wiring and pipe connections.
- Installation: Install the UPS3, ensuring proper alignment and tight seals. Use the installer plug for easy wiring.
- Configuration: Select the appropriate control mode based on your heating system's needs.
- Commissioning: Open the isolation valves and turn on the power, checking for leaks and proper operation.
Compatibility
The Grundfos UPS3 15-50/65 is compatible with domestic heating systems up to 30kW. It replaces many older Grundfos models and can be used in new and existing systems. Verify compatibility using the GO Replace app.
Care
- Regular Inspections: Check for leaks or unusual noises periodically.
- Cleaning: Use a damp cloth to clean the exterior. Do not use harsh chemicals.
- Deblocking: If the pump blocks, use the servicing screw to access and clear the pump shaft.
- Professional Servicing: For any major issues or repairs, contact a qualified HVAC technician.
