Multiport valve and Intelliflo priming speeds

I have a question regarding switching my multiport valve to different settings and then having to re-prime my Intelliflo VSP. I can't change the multiport settings while the pump is running but the pump primes at 3450.

How do I change the settings without blowing my plumbing or filter apart? Do people limit the prime speed or do you just let it prime at full blast or some other method?
