How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Check the label on your pump head. It should say Grundfos, Type UPS 15-50 AC AO (or AC A0) and P/N 59965502.
- Look for the Fagor logo with the code MU1021400 on the same label.
- Check the marked data: 230 V ~, 50 Hz, 2 µF and three power ratings of 45, 70, and 100 W.
- Check the rating plate of your boiler. It should be a Fagor FEE-20/2N or a Fagor FE-20E/2B.
- Do not consider it equivalent to another UPS 15-50 from Grundfos with a different code, such as 59525600. Always compare the codes.
- Any questions? Send us a photo of your pump's label and the boiler's PCB from the Contact section, or call 911 17 77 77.
