How to check if reference 0020047180 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Look for the model SDZ-2/DC E-V and the code 0020047180 on your pump's label.
2. If your pump has 0020075439, 0020111412, 0020247049, or 0020016182, also compare the model SDZ-2/DC E-V and the 612116: these are codes to be confirmed.
3. Check that its label indicates 230 V, 50 Hz, and 27 W.
4. If your boiler is an Isomax F35 H-MOD, Isotwin F30 H-MOD 35, or Isofast 21 Condens F30-B/1 or F35-B/1, this pump has already been confirmed. For another model, call 911 17 77 77 or send us a photo of the label and the PCB.
