How do you bleed new style grundfos pumps?

[Stratf01]

Just wondering how these new style pumps can be bled if there's no longer a big bleed screw in middle?

Any comments on this hugely appreciated.

Thank you

Grundfos advise running the pump at "full speed" (which is the default setting, CC3) for 10 minutes, I certainly would not recommend this, especially in a OV system, if I was installing a new pump (only) I would just leave the outlet pipe loosely connected and open the pump inlet valve to vent any air, then retighten, remember the recommended venting is for the pump only.
I have a Wilo Yonos Pico circ pump and there is a 10 min venting facility whereby the pump speeds up and slows down automatically for this 10 minute period, I didn't use it when I installed mine.

Thanks so much for the advice

Really appreciate it
